- On most rural interstate freeways in Washington, what is the maximum posted speed limit for passenger vehicles?
Correct answer: 70 mph
Washington sets a maximum of 70 mph for passenger cars on certain rural interstate freeways. Heavy trucks (GVWR over 10,000 lbs) are capped at 60 mph. The posted limit always controls.
- In Washington, what is the default maximum speed limit on a state highway where no other speed is posted?
Correct answer: 60 mph
Under RCW 46.61.400, absent a posted limit the maximum on Washington state highways is 60 mph. County roads default to 50 mph and city/town streets to 25 mph.
- Unless otherwise posted, what is the maximum speed limit on city and town streets in Washington?
Correct answer: 25 mph
Washington's basic rule (RCW 46.61.400) sets the default speed limit on city and town streets at 25 mph. Always obey lower posted limits in residential and business districts.
- What is the speed limit in a Washington school zone when the warning lights are flashing or children are present?
Correct answer: 20 mph
Washington law sets a 20 mph limit in marked school zones during the posted times or when children are present. Fines in school zones are doubled.
- What is the legal blood alcohol concentration (BAC) limit for a driver age 21 or older in Washington?
- 0.08 percent
- 0.05 percent
- 0.10 percent
- 0.02 percent
Correct answer: 0.08 percent

- What is the BAC limit for a driver operating a commercial motor vehicle (CDL) in Washington?
- 0.04 percent
- 0.08 percent
- 0.02 percent
- 0.10 percent
Correct answer: 0.04 percent
Under RCW 46.25.110, a commercial driver is over the limit at a BAC of 0.04 percent, half the limit for non-commercial drivers.
- After a DUI conviction in Washington, what device is the driver generally required to install before driving?
- An ignition interlock device
- A dashboard camera
- A speed limiter
- A GPS tracker
Correct answer: An ignition interlock device
Washington requires an ignition interlock device (IID) for DUI convictions (RCW 46.20.720). The driver must blow a clean breath sample before the vehicle will start.
- For a first-time ignition interlock restriction in Washington, the device must generally remain installed for at least how long?
- One year
- 30 days
- Six months
- Ten years
Correct answer: One year
Under RCW 46.20.720, a first interlock restriction lasts one year, five years for a second, and ten years for a third. Removal also requires four months of compliance with no violations.
- Under Washington's E-DUI law, what may an officer do if they see a driver simply holding a cell phone?
- Pull the driver over, because handheld use is a primary offense
- Nothing, unless the driver commits another violation first
- Issue only a written warning
- Cite the driver only if they were texting
Correct answer: Pull the driver over, because handheld use is a primary offense
Washington's 2017 E-DUI (Driving Under the Influence of Electronics) law makes holding a personal electronic device a primary offense. An officer can stop you just for holding the device while driving.
- Under Washington's E-DUI law, when may you legally hold and use a handheld cell phone while in the driver's seat?
- Never while driving, including while stopped at a red light or in traffic
- Whenever the vehicle is stopped at a red light
- While stopped in slow or stalled traffic
- Any time, as long as you are not moving
Correct answer: Never while driving, including while stopped at a red light or in traffic
Washington's E-DUI law bars holding a personal electronic device while driving, including when stopped at a light or in traffic. Hands-free use is limited to a single touch or swipe.
- What is the fine for a first E-DUI (distracted driving) ticket in Washington?
Correct answer: $136
A first E-DUI ticket in Washington costs $136. A second offense within five years rises to $234, and the violation is reported to insurers.
- Under Washington's Move Over law, what must you do when approaching a stopped emergency vehicle, tow truck, or work vehicle with flashing lights?
- Move over a lane if safe, or slow down if you cannot change lanes
- Maintain your speed and stay in your lane
- Come to a complete stop in the travel lane
- Speed up to clear the area quickly
Correct answer: Move over a lane if safe, or slow down if you cannot change lanes
Washington's Move Over law (RCW 46.61.212) requires drivers to vacate the lane next to a stopped emergency, tow, or assistance vehicle with lights on, or to slow to a reasonable speed if changing lanes is not possible.
- In Washington, when must a child ride in a rear-facing car seat?
- Until the child is at least 2 years old
- Until the child is at least 6 months old
- Until the child is at least 1 year old
- Until the child weighs 40 pounds
Correct answer: Until the child is at least 2 years old
Under RCW 46.61.687, children must ride rear-facing until they are at least 2 years old, unless a doctor documents a medical reason to do otherwise.
- In Washington, children who have outgrown a rear-facing seat must ride in a harnessed car seat until at least what age?
Correct answer: Age 4
Washington law requires a forward-facing car seat with a harness for children from age 2 until at least age 4, until they outgrow the seat's height or weight limits.
- In Washington, a child age 4 or older must use a booster seat until they reach what height?
- 4 feet 9 inches tall
- 4 feet 0 inches tall
- 5 feet 0 inches tall
- 4 feet 5 inches tall
Correct answer: 4 feet 9 inches tall
Under RCW 46.61.687, children 4 and older must ride in a booster seat until they are 4 feet 9 inches tall, so the adult seat belt fits correctly.
- Under Washington law, where must children under age 13 ride when practical?
- In the back seat
- In the front passenger seat
- In any seat with an airbag
- On an adult's lap
Correct answer: In the back seat
Washington's child restraint law requires children under 13 to ride in the back seat whenever it is practical to do so, away from front passenger airbags.
- Is the seat belt law for adults in Washington a primary or secondary offense?
- Primary, an officer can stop you solely for not buckling up
- Secondary, you can only be cited after another violation
- It applies only to front-seat passengers
- It is not enforced for drivers over 18
Correct answer: Primary, an officer can stop you solely for not buckling up
Under RCW 46.61.688, seat belt use is a primary offense in Washington. An officer may stop and cite you for an unbuckled occupant even if no other violation occurred.
- In Washington, who in the vehicle is required to wear a seat belt?
- The driver and every passenger age 16 and older (younger riders need proper restraints)
- Only the driver
- Only front-seat occupants
- Only occupants under age 18
Correct answer: The driver and every passenger age 16 and older (younger riders need proper restraints)
RCW 46.61.688 requires the driver and all passengers 16 and older to wear a seat belt. Passengers under 16 must be in a belt or an appropriate child restraint.
- What is the minimum age to apply for an instruction permit in Washington?
- 15 years old (and enrolled in driver education)
- 14 years old
- 16 years old
- 18 years old
Correct answer: 15 years old (and enrolled in driver education)
In Washington a teen may get an instruction permit at 15 if enrolled in a driver education course, or at 15 and a half without one. A licensed driver with at least five years of driving experience must supervise.
- During what hours may a Washington intermediate (teen) license holder NOT drive without a qualifying supervising driver?
- Between 1 a.m. and 5 a.m.
- Between 10 p.m. and 6 a.m.
- Between midnight and 4 a.m.
- Between 11 p.m. and 5 a.m.
Correct answer: Between 1 a.m. and 5 a.m.
Washington's intermediate license imposes a curfew from 1 a.m. to 5 a.m. unless the teen is supervised by a licensed driver age 25 or older, or driving for work or agriculture.
- For the first 6 months, which passengers may a Washington intermediate license holder carry?
- Only immediate family members; no other passengers under 20
- Up to three friends under 20
- Any number of passengers
- Only one passenger of any age
Correct answer: Only immediate family members; no other passengers under 20
For the first six months, a Washington intermediate licensee may not carry passengers under 20 who are not immediate family. Restrictions ease after six months but never allow more than three.
- After the first 6 months, how many non-family passengers under age 20 may a Washington intermediate license holder carry?
- No more than three
- No more than one
- Unlimited
- No more than five
Correct answer: No more than three
After six months on the intermediate license, a Washington teen may carry no more than three passengers under 20 who are not immediate family.
- How long do the passenger and nighttime restrictions on a Washington intermediate license last?
- Until age 18 or one year of violation-free driving, whichever comes first
- Exactly 90 days
- Until the driver turns 21
- They never expire
Correct answer: Until age 18 or one year of violation-free driving, whichever comes first
Washington's intermediate license restrictions end when the driver turns 18 or after one year of safe, ticket-free driving, whichever happens first.
- When entering a roundabout in Washington, who has the right-of-way?
- Traffic already circulating inside the roundabout
- The driver entering from the right
- The larger vehicle
- Whichever driver arrives first
Correct answer: Traffic already circulating inside the roundabout
Washington roundabouts move counterclockwise. Drivers entering must yield to traffic already in the circle, look left for a gap, then enter and exit at their street.
- What direction does traffic flow in a Washington roundabout?
- Counterclockwise
- Clockwise
- Either direction, depending on the exit
- Whichever way avoids other cars
Correct answer: Counterclockwise
In Washington, all vehicles travel counterclockwise around the center island of a roundabout. Stay in your lane and use your right signal as you approach your exit.
- In Washington, when must you turn on your headlights in relation to your windshield wipers?
- Whenever your wipers are running due to rain, snow, or fog
- Only after dark
- Headlights and wipers are never linked by law
- Only when wipers are on their fastest setting
Correct answer: Whenever your wipers are running due to rain, snow, or fog
Washington law (RCW 46.37.020) requires headlights any time windshield wipers are in continuous use because of weather, in addition to from a half hour after sunset to a half hour before sunrise.
- In Washington, you must use your headlights from a half hour after sunset until when?
- A half hour before sunrise
- Exactly sunrise
- One hour after sunrise
- Noon
Correct answer: A half hour before sunrise
Washington requires lighted headlights from a half hour after sunset to a half hour before sunrise, and whenever visibility drops below 1,000 feet.
- A Washington driver should follow the rule of using a safe following distance commonly described as what?
- At least a 3 to 4 second gap behind the vehicle ahead
- Exactly one car length per trip
- 10 feet regardless of speed
- Whatever feels comfortable
Correct answer: At least a 3 to 4 second gap behind the vehicle ahead
The Washington Driver Guide recommends a minimum 3 to 4 second following distance, increasing it in rain, fog, or other poor conditions to maintain a safe space cushion.
- What is the best defensive-driving practice for managing your space on a Washington roadway?
- Aim high in steering and keep a space cushion on all sides of your vehicle
- Stare at the car directly in front of you
- Drive as close to other cars as possible
- Ignore mirrors once you are in your lane
Correct answer: Aim high in steering and keep a space cushion on all sides of your vehicle
The Washington Driver Guide teaches drivers to look well ahead (aim high), scan, and keep a cushion of space around the vehicle so there is room to react to hazards.
- At a four-way stop in Washington, who proceeds first when two vehicles arrive at the same time?
- The driver on the right goes first
- The driver on the left goes first
- The faster vehicle goes first
- The larger vehicle goes first
Correct answer: The driver on the right goes first
Washington right-of-way rules say that when two vehicles reach a four-way stop at the same time, the driver on the left yields to the driver on the right.
- When you approach a stopped school bus with red lights flashing on a two-lane Washington road, what must you do?
- Stop in both directions until the lights stop flashing and the bus moves
- Slow to 20 mph and pass carefully
- Pass on the left if no children are visible
- Only stop if you are behind the bus
Correct answer: Stop in both directions until the lights stop flashing and the bus moves
On an undivided road in Washington, traffic in both directions must stop for a school bus with flashing red lights and an extended stop arm until the lights are off.
- On a multi-lane road in Washington, when must oncoming traffic stop for a school bus loading children?
- When the road has fewer than three marked lanes (no median or barrier)
- Always, on any number of lanes
- Never, on any multi-lane road
- Only when a crossing guard is present
Correct answer: When the road has fewer than three marked lanes (no median or barrier)
In Washington, oncoming drivers do not have to stop for a school bus when the roadway has three or more marked lanes, or is divided by a median or barrier. Traffic behind the bus always stops.
- When you encounter an emergency vehicle with its siren and lights on in Washington, what must you do?
- Pull over to the right edge of the road and stop until it passes
- Speed up to stay ahead of it
- Stop immediately in your current lane
- Continue at the same speed
Correct answer: Pull over to the right edge of the road and stop until it passes
Washington law requires drivers to yield to an emergency vehicle using lights and siren by pulling to the right edge of the road and stopping until it has passed.
- In Washington, when sharing the road with a bicyclist, how much room should a driver give when passing?
- At least 3 feet of clearance
- At least 1 foot of clearance
- No specific distance is required
- At least 10 feet of clearance
Correct answer: At least 3 feet of clearance
Washington law (RCW 46.61.110) requires drivers to give bicyclists at least 3 feet of clearance when passing, more at higher speeds, and to wait for a safe gap.
- What does a solid yellow center line on your side of a two-lane Washington road mean?
- You may not pass or cross it to overtake another vehicle
- You may pass freely whenever clear
- It marks the edge of the roadway
- It indicates a one-way street
Correct answer: You may not pass or cross it to overtake another vehicle
A solid yellow line on your side means passing is prohibited. A broken yellow line on your side allows passing when it is safe and clear.
- In Washington, what does a flashing red traffic signal require you to do?
- Stop completely, then proceed when safe (treat it like a stop sign)
- Slow down but do not stop
- Stop and wait for the light to turn green
- Proceed without stopping if no cars are present
Correct answer: Stop completely, then proceed when safe (treat it like a stop sign)
A flashing red light is treated like a stop sign: come to a full stop, yield to traffic and pedestrians, then proceed when it is safe.
- In Washington, what does a flashing yellow arrow on a left-turn signal mean?
- You may turn left after yielding to oncoming traffic and pedestrians
- Left turns are prohibited
- You have a protected left turn with no yielding required
- You must stop and wait for a green arrow
Correct answer: You may turn left after yielding to oncoming traffic and pedestrians
A flashing yellow left-turn arrow means left turns are permitted but you must yield to oncoming traffic and pedestrians before turning.
- What is the shape and meaning of a regulatory YIELD sign in Washington?
- A downward-pointing triangle; slow down and give the right-of-way to other traffic
- An octagon; come to a full stop every time
- A diamond; warns of a hazard ahead
- A rectangle; provides general information
Correct answer: A downward-pointing triangle; slow down and give the right-of-way to other traffic
A yield sign is a downward-pointing triangle. Drivers must slow, be ready to stop, and give the right-of-way to traffic and pedestrians before merging or crossing.
- In Washington, what color and shape are warning signs that alert you to hazards such as curves or merging traffic?
- Yellow diamond-shaped signs
- Red octagonal signs
- Green rectangular signs
- Blue circular signs
Correct answer: Yellow diamond-shaped signs
Warning signs in Washington are yellow diamonds. They alert drivers to upcoming conditions such as curves, intersections, merges, or pedestrian crossings.
- What does a white rectangular regulatory sign in Washington generally tell you?
- A traffic law or rule you must obey, such as a speed limit or one-way restriction
- A recreation or tourist destination
- A scenic point of interest
- A warning of an upcoming hazard
Correct answer: A traffic law or rule you must obey, such as a speed limit or one-way restriction
White rectangular signs are regulatory signs that state laws you must follow, such as speed limits, lane use, or turn restrictions.
- On a Washington freeway, what color are the signs showing exits, distances, and route guidance?
Correct answer: Green
Green signs provide guidance information such as directions, distances, and exits. Orange signs indicate construction or maintenance zones.
- What do orange signs and cones indicate on a Washington roadway?
- A construction, maintenance, or work zone ahead
- A school zone
- A scenic route
- A no-parking area
Correct answer: A construction, maintenance, or work zone ahead
Orange signs, cones, and barrels mark work zones in Washington. Slow down, watch for workers, and obey reduced speed limits; fines are increased in work zones.
- In Washington, what must a driver do at a marked or unmarked crosswalk when a pedestrian is crossing?
- Stop and yield the right-of-way to the pedestrian
- Honk to warn the pedestrian to hurry
- Proceed if the pedestrian is not yet in your lane
- Slow down only if a signal is present
Correct answer: Stop and yield the right-of-way to the pedestrian
Washington law (RCW 46.61.235) requires drivers to stop and yield to pedestrians at any marked or unmarked crosswalk, including intersections without painted lines.
- When driving in fog on a Washington highway, which lights should you use?
- Low-beam headlights
- High-beam headlights
- Parking lights only
- Hazard flashers while moving
Correct answer: Low-beam headlights
In fog, use low-beam headlights. High beams reflect off the fog and reduce visibility. Slow down and increase your following distance in low-visibility conditions.
- A posted school-zone speed limit applies 'when children are present.' During a school holiday with no children anywhere near the school, how does this affect your obligation?
- The reduced limit still applies at all hours regardless of children
- The reduced limit may not apply when no children are present, but you should slow if there is any doubt
- You may always exceed the regular road limit in a school zone
- School-zone limits never depend on whether children are present
Correct answer: The reduced limit may not apply when no children are present, but you should slow if there is any doubt
The reduced limit may not apply when no children are present, but you should slow if there is any doubt. A 'when children are present' restriction ties the lower limit to the actual presence of children, yet a cautious driver slows whenever it is uncertain. You may never exceed the normal road limit, and many zones do depend on children being present.
- You are driving the posted 30 mph speed on a street that enters a school zone where flashing yellow beacons have just begun operating. What must you do?
- Continue at 30 mph because you were already at the road limit
- Stop completely at the first beacon
- Slow to the lower school-zone limit indicated by the flashing beacons
- Speed up to pass through the zone faster
Correct answer: Slow to the lower school-zone limit indicated by the flashing beacons
You must slow to the lower school-zone limit indicated by the flashing beacons. Flashing beacons activate the reduced school-zone speed, so the normal road limit no longer applies while they operate. You are not required to stop at the beacons, and speeding through the zone is both unsafe and unlawful.
- A driver under 21 is stopped and a breath test shows a blood alcohol concentration of 0.01 percent. Under zero-tolerance laws, how is this treated?
- It is legal because it is well under the 0.08 adult limit
- It is legal because only a 0.05 reading matters for young drivers
- It is a violation because zero-tolerance laws prohibit nearly any measurable alcohol for under-21 drivers
- It is treated the same as an adult driver at 0.08
Correct answer: It is a violation because zero-tolerance laws prohibit nearly any measurable alcohol for under-21 drivers
It is a violation because zero-tolerance laws prohibit nearly any measurable alcohol for under-21 drivers. These laws set the limit at essentially zero, so a reading such as 0.01 percent can result in penalties even though it is far below the 0.08 adult standard. The under-21 driver is not judged by the adult limit.
- Two seconds after the car ahead of you passes a roadside mailbox, you reach that same mailbox while driving in clear, dry weather. What does this tell you about your following distance?
- It is too short, because at least three seconds should pass before you reach the marker
- It is exactly right, because two seconds is the recommended cushion
- It is too long, and you should move closer
- It is acceptable as long as you are below the speed limit
Correct answer: It is too short, because at least three seconds should pass before you reach the marker
Your following distance is too short, because at least three seconds should pass before you reach the marker. Reaching the mailbox in only two seconds means you are inside the three-second minimum taught for good, dry conditions and would not have enough time to react if the car ahead stopped suddenly. Two seconds is below the standard, the gap is not too long, and staying under the speed limit does not make a short gap safe.
- Why does the three-second following rule use a count of seconds rather than a fixed number of feet or car lengths?
- Because seconds are easier to convert into miles per hour
- Because a time-based gap automatically adjusts the actual distance as your speed changes
- Because car lengths are illegal to use as a measurement
- Because feet cannot be estimated while the vehicle is moving
Correct answer: Because a time-based gap automatically adjusts the actual distance as your speed changes
The rule uses seconds because a time-based gap automatically adjusts the actual distance as your speed changes. A fixed footage that is safe at low speed becomes far too small at highway speed, but counting seconds keeps the cushion proportional to how fast you are traveling. Seconds are not chosen for unit conversion, car lengths are not illegal, and feet can be roughly estimated; the real advantage is automatic scaling with speed.
- Compared with driving on a clear, dry day, how should you adjust your following distance when the road is covered in snow or ice?
- Keep the same gap, because following distance does not depend on the road surface
- Shorten the gap so other drivers cannot cut in front of you
- Lengthen the gap well beyond the normal minimum to allow for much longer stopping distances
- Eliminate the gap and rely entirely on your brakes
Correct answer: Lengthen the gap well beyond the normal minimum to allow for much longer stopping distances
You should lengthen the gap well beyond the normal minimum to allow for much longer stopping distances. Snow and ice greatly reduce tire traction, so a vehicle needs far more room to stop, and the usual three-second cushion is no longer enough. Keeping the same gap ignores the lost traction, shortening it is dangerous, and relying only on brakes on a slick surface invites a skid.
- When you stop behind another vehicle at a red light or in traffic, roughly how much space should you leave so you have room to maneuver if needed?
- Just enough that your bumper nearly touches the vehicle ahead
- At least three full car lengths in all situations
- No space, so following vehicles cannot squeeze in
- Enough to see the rear tires of the vehicle ahead touching the pavement
Correct answer: Enough to see the rear tires of the vehicle ahead touching the pavement
You should leave enough space to see the rear tires of the vehicle ahead touching the pavement. That guideline keeps a usable cushion when stopped, letting you steer around the vehicle if it stalls or if you must avoid being pushed into it from behind. Nearly touching bumpers leaves no room, a rigid three car lengths is impractical when stopped, and leaving no space removes your escape route.
- When are mirror-only checks not enough, so you must also turn your head to look directly at the area beside your vehicle?
- Only when parallel parking on a hill
- Only when driving in heavy fog
- When backing straight out of a driveway in a quiet area
- When merging onto a freeway or moving over for a lane change
Correct answer: When merging onto a freeway or moving over for a lane change
You must turn your head to look beside your vehicle when merging onto a freeway or moving over for a lane change. These sideways movements can put you into a lane where another vehicle sits in the area your mirrors cannot show, so a direct over-the-shoulder look is required. Parallel parking on a hill, heavy fog, and backing straight out of a quiet driveway are not the situations the blind-spot head check is specifically meant to cover before merging.
- Why can a properly adjusted set of mirrors still leave a blind spot beside your car?
- Because mirrors only work when the headlights are on
- Because the glass in side mirrors curves the wrong way
- Because mirrors cannot cover the area to the side and slightly behind where a whole vehicle can hide
- Because mirrors stop reflecting at highway speeds
Correct answer: Because mirrors cannot cover the area to the side and slightly behind where a whole vehicle can hide
Even well-adjusted mirrors leave a blind spot because they cannot cover the area to the side and slightly behind your car where a whole vehicle can hide. The angles the rearview and side mirrors capture simply do not include those zones, which is why an over-the-shoulder glance is needed. Mirrors work in daylight without headlights, the glass curve actually widens the view, and mirrors keep reflecting at any speed.
- Driving on a slick road, you feel the rear of your car start to slide sideways. Besides steering where you want to go, what should you do with the brake and accelerator?
- Avoid hard braking and ease your foot off the accelerator
- Press the brake firmly and floor the accelerator at the same time
- Pump the brake rapidly while accelerating
- Hold the accelerator steady and ignore the slide
Correct answer: Avoid hard braking and ease your foot off the accelerator
You should avoid hard braking and ease your foot off the accelerator. Lifting off the gas lets the drive wheels regain traction, and staying off the brakes prevents the wheels from locking, both of which help you steer out of the slide. Flooring the gas, braking hard, or holding the accelerator steady all keep the tires from regaining the grip needed to recover.
- A driver going too fast on a wet curve suddenly jerks the steering wheel and stabs the brakes, sending the car into a skid. Which combination of mistakes most directly caused the skid?
- Driving with the headlights on and the radio playing
- Excessive speed combined with abrupt steering and braking inputs
- Keeping both hands on the wheel and looking far ahead
- Using the turn signal before entering the curve
Correct answer: Excessive speed combined with abrupt steering and braking inputs
Excessive speed combined with abrupt steering and braking inputs most directly caused the skid. Sudden, forceful actions overwhelm the limited grip available on a wet curve, breaking the tires loose, and too much speed leaves no traction in reserve. Headlights and radio, proper hand position with eyes ahead, and signaling do not cause a skid; the abrupt inputs at high speed do.
- At higher speeds on a wet road, why does hydroplaning become more likely than at lower speeds?
- Because the tires spin too slowly to throw off water
- Because higher speed cools the tires and reduces grip
- Because the faster a tire moves, the less time it has to push water out of the way, so it rides up onto the water
- Because the engine pulls water up under the car
Correct answer: Because the faster a tire moves, the less time it has to push water out of the way, so it rides up onto the water
Hydroplaning becomes more likely at higher speeds because the faster a tire moves, the less time it has to push water out of the way, so it rides up onto the water. Below a certain speed the tread can channel water aside, but as speed climbs the water cannot escape fast enough and lifts the tire off the pavement. The tires are spinning faster, not slower, and engine action and tire temperature are not what cause hydroplaning.
- Which vehicle is most at risk of hydroplaning when driving fast through standing water on the road?
- A vehicle with worn, balding tires that have little tread
- A vehicle with brand-new tires and deep tread
- A vehicle traveling well below the speed limit
- A heavy vehicle moving slowly through a puddle
Correct answer: A vehicle with worn, balding tires that have little tread
A vehicle with worn, balding tires that have little tread is most at risk of hydroplaning. Tread grooves channel water away from the contact patch, so tires with little tread cannot move the water and ride up onto it much more easily. Deep new tread resists hydroplaning, and driving slowly gives any tire time to disperse water, lowering the risk rather than raising it.
- You are following a school bus that begins to slow and activates flashing amber (yellow) lights before it comes to a stop. What does this signal tell you to do?
- Pass the bus immediately while it is still moving slowly
- Maintain your speed because amber lights apply only to oncoming traffic
- Sound your horn to encourage the bus to keep moving
- Prepare to stop because the bus is about to halt and switch on its red lights
Correct answer: Prepare to stop because the bus is about to halt and switch on its red lights
Preparing to stop because the bus is about to halt and switch on its red lights is correct. Flashing amber lights are a warning that the bus is preparing to stop to load or unload children, so following drivers should slow and get ready to come to a full stop when the red lights begin flashing. Passing, holding your speed, or honking ignores the warning and risks not being able to stop in time.
- On a two-lane road you have stopped for a school bus displaying flashing red lights and an extended stop arm, and a child who got off the bus is now crossing in front of it. The red lights stop flashing and the stop arm folds back in, but the child is still in the roadway. What should you do?
- Begin driving as soon as the red lights turn off, regardless of the child
- Accelerate past on the left because the bus has finished loading
- Remain stopped until the child has finished crossing and is safely off the road
- Edge forward slowly to encourage the child to hurry across
Correct answer: Remain stopped until the child has finished crossing and is safely off the road
Remaining stopped until the child has finished crossing and is safely off the road is correct. Even after a bus turns off its signals, you must continue to yield to pedestrians, and children near a bus are unpredictable, so you wait until the roadway is clear. Driving forward, passing, or creeping toward the child endangers the pedestrian regardless of the bus signal status.
- A motorcyclist riding ahead of you is positioned toward the left side of the lane rather than the center. How should you interpret the amount of following space the motorcycle needs?
- A motorcycle stops faster than a car, so you can follow more closely than usual
- Allow a greater following distance, because a motorcycle can stop quickly or be upset by road hazards a car would ignore
- Tailgate closely so the rider knows you intend to pass
- Treat the lane as shared and drive alongside the motorcycle in the same lane
Correct answer: Allow a greater following distance, because a motorcycle can stop quickly or be upset by road hazards a car would ignore
Allowing a greater following distance is correct, because a motorcycle can stop in a short distance or be thrown off balance by potholes, gravel, or debris that would not affect a car, and it may also slow without brake lights by downshifting. Following too closely, tailgating, or sharing the lane leaves no room to react if the rider brakes or swerves suddenly.
- You are stopped at a red light and a motorcycle is stopped in the lane directly ahead of you. When the light turns green, what is the best practice for sharing that lane space?
- Pull up beside the motorcycle so two vehicles occupy the single lane
- Move forward in the same lane next to the rider to save space
- Give the motorcyclist the full lane and follow at a safe distance rather than crowding the rider
- Edge close behind so the rider feels pressured to move quickly
Correct answer: Give the motorcyclist the full lane and follow at a safe distance rather than crowding the rider
Giving the motorcyclist the full lane and following at a safe distance is correct. A motorcycle is entitled to the entire width of a traffic lane, and the rider may need that space to maneuver around hazards or maintain balance, so you should never share the lane or crowd the rider. Pulling alongside or tailgating removes the rider's room to react and is unsafe.
- While driving on a highway you see a sign reading 'Road Work Ahead' followed by a 'Fines Double in Work Zones' sign, even though no workers are currently visible. How does the work-zone speed limit apply?
- It applies only when workers are actually present in the zone
- It applies the entire time you are in the marked work zone, whether or not workers are visible
- It applies only on weekdays during normal business hours
- It is optional until you reach the equipment in the zone
Correct answer: It applies the entire time you are in the marked work zone, whether or not workers are visible
Applying the entire time you are in the marked work zone, whether or not workers are visible, is correct. Posted work-zone speed limits are in effect for the full length of the zone from the first sign, and increased fines apply throughout, because hazards such as uneven pavement, narrowed lanes, and equipment exist even when no crew is in sight. Waiting until you see workers or treating the limit as optional is both unsafe and illegal.
- You are approaching a highway work zone where a flagger is standing in the road holding a STOP/SLOW paddle that is turned to the SLOW side. What are you required to do?
- Ignore the flagger and follow only the posted signs
- Come to a complete stop and wait until the flagger leaves the roadway
- Speed up to clear the area before the paddle is turned to STOP
- Obey the flagger and reduce your speed, treating the flagger's directions as you would a traffic signal
Correct answer: Obey the flagger and reduce your speed, treating the flagger's directions as you would a traffic signal
Obeying the flagger and reducing your speed, treating the flagger's directions as you would a traffic signal, is correct. In a work zone a flagger's instructions carry the force of law and override conflicting signs or signals, so a SLOW paddle means proceed at reduced speed with caution. Ignoring the flagger, stopping unnecessarily, or speeding up disregards lawful traffic control and endangers the crew.
- In wet or rainy weather, why do motorcyclists need extra consideration from the drivers around them?
- Motorcycles are unaffected by rain because of their narrow tires
- Slippery surfaces and reduced traction affect a two-wheeled motorcycle more, so drivers should allow more room and avoid sudden moves near them
- Motorcycles must leave the road entirely whenever it rains
- Rain improves a motorcycle's grip, so no extra caution is needed
Correct answer: Slippery surfaces and reduced traction affect a two-wheeled motorcycle more, so drivers should allow more room and avoid sudden moves near them
Slippery surfaces and reduced traction affecting a two-wheeled motorcycle more, so drivers should allow more room and avoid sudden moves near them, is correct. A motorcycle relies on only two contact patches for balance and braking, so rain, painted lines, and metal surfaces make it far easier to skid than a four-wheeled vehicle. Drivers should give riders extra space and avoid abrupt braking or lane changes that could force a rider into a slick surface.
- Interstate highway route shields are shaped like a shield with a particular color scheme. What colors appear on a standard Interstate route marker?
- Black and yellow
- Red, white, and blue
- Green and white
- Orange and black
Correct answer: Red, white, and blue
Red, white, and blue is correct. The Interstate route shield uses a blue background with a red top band and white route numerals, distinguishing it from other route markers.
- A U.S. route number is shown inside a sign shaped like a rounded shield in black and white. How does a U.S. route marker differ in color from an Interstate marker?

- Both markers use the same red, white, and blue colors
- The U.S. route marker is green while the Interstate marker is brown
- The U.S. route marker is orange while the Interstate marker is yellow
Correct answer: The U.S. route marker is black and white while the Interstate marker is red, white, and blue
The U.S. route marker is black and white while the Interstate marker is red, white, and blue is correct. U.S. highway shields use black numerals on a white shield, unlike the colored Interstate shield.
- A small marker showing a single rising number, such as 'MILE 142,' is posted at regular intervals along a highway shoulder. What is the purpose of these mile markers?
- They tell you the speed limit for that stretch of road
- They mark the number of lanes ahead
- They indicate how many exits remain on the route
- They show distance along the highway and help locate your position for emergencies
Correct answer: They show distance along the highway and help locate your position for emergencies
They show distance along the highway and help locate your position for emergencies is correct. Mileposts count distance from a fixed point and let drivers report a precise location to emergency services.
- An exit on a freeway is labeled 'EXIT 142' on a green guide sign, and the next exit is 'EXIT 145.' What does this numbering system most commonly tell a driver?
- Exit 145 is exactly three exits past Exit 142
- The numbers are random and carry no distance meaning
- The next exit is three blocks away
- The exit number corresponds to the nearest milepost, so the next exit is about three miles away
Correct answer: The exit number corresponds to the nearest milepost, so the next exit is about three miles away
The exit number corresponds to the nearest milepost, so the next exit is about three miles away is correct. Most freeways use mileage-based exit numbering, so the gap between exit numbers approximates the distance in miles.
- A green guide sign over a freeway lane has a small yellow 'EXIT ONLY' panel attached at its bottom. What does that yellow tab tell a driver?
- The lane is the fastest way to continue straight on the freeway
- Only trucks may use the lane
- The lane beneath the sign leaves the freeway and does not continue as a through lane
- The lane is closed for construction
Correct answer: The lane beneath the sign leaves the freeway and does not continue as a through lane
The lane beneath the sign leaves the freeway and does not continue as a through lane is correct. A yellow EXIT ONLY panel warns that the lane will be forced off at the exit, so a driver wishing to continue must move over.

- At a railroad crossing the crossbuck sign has a small additional sign below it reading '3 TRACKS.' What does this number plate tell a driver?
- Trains pass exactly three times each day
- There are three separate sets of railroad tracks at the crossing
- The crossing is three miles ahead
- Drivers may cross only three vehicles at a time
Correct answer: There are three separate sets of railroad tracks at the crossing
Three separate sets of tracks is correct. The number plate beneath a crossbuck states how many tracks make up the crossing, alerting drivers that more than one train could approach on different tracks. It does not count daily trains, give a distance, or limit how many vehicles may cross.
- A rectangular sign mounted high over a freeway lane shows a downward arrow pointing directly at that lane along with a route number or destination. What does this overhead lane sign tell a driver?
- The lane is closed and must be exited immediately
- Drivers in that lane must come to a complete stop
- The lane beneath the arrow leads to the indicated route or destination
- Passing is prohibited in the lane below
Correct answer: The lane beneath the arrow leads to the indicated route or destination
The lane beneath the arrow leads to the indicated route is correct. Overhead guide signs use a downward arrow over a specific lane to show that staying in that lane will take the driver to the route or destination named. The arrow does not signal a closed lane, a stop, or a passing restriction.
- Driving along a highway you feel and hear a sudden continuous vibration and rumbling as your tires cross a series of grooves cut into the shoulder edge. What is the purpose of these rumble strips?
- To mark a legal passing zone
- To indicate the start of a school zone
- To show where vehicles may make a U-turn
- To alert a driver, through noise and vibration, that the vehicle is drifting off the travel lane
Correct answer: To alert a driver, through noise and vibration, that the vehicle is drifting off the travel lane
Alerting a driver that the vehicle is drifting off the lane is correct. Rumble strips are grooves placed along edges or centerlines that create noise and vibration to warn an inattentive or drowsy driver to steer back into the lane. They do not mark passing zones, school zones, or U-turn locations.
- A driver who scans the traffic scene by glancing well down the road, then back to the near area, and frequently to the mirrors is practicing which defensive-driving habit?
- Keeping the eyes moving rather than fixing on one point
- Driving with only peripheral vision
- Staring at the lane line for guidance
- Watching only the bumper of the car ahead
Correct answer: Keeping the eyes moving rather than fixing on one point
Keeping the eyes moving rather than fixing on one point is the habit being described. Continuously shifting your gaze far ahead, to the near road, and to the mirrors lets you spot hazards early and avoid the tunnel vision that comes from staring at a single object.
- On a multilane road, the lane that generally gives a defensive driver the most space cushion and escape options is best described as the one where you can do what?
- Stay boxed in tightly between two vehicles for protection
- Match the exact position of the car beside you
- Keep open space on at least one side so you have somewhere to go
- Always remain in the far-left lane regardless of traffic
Correct answer: Keep open space on at least one side so you have somewhere to go
Keeping open space on at least one side so you have somewhere to go is correct. A defensive driver positions the vehicle so that an escape path stays available, avoiding being trapped between vehicles where there is no room to react.
- You are approaching a green traffic light that has been green for a long time as you near it. What defensive label describes this signal and how should you treat it?
- A fresh green that will definitely stay green
- A stale green that may change soon, so be ready to stop
- A protected signal that removes any need to slow
- A malfunctioning light you should drive through quickly
Correct answer: A stale green that may change soon, so be ready to stop
A stale green that may change soon, so be ready to stop, is the correct interpretation. A light that has been green a while is likely to turn yellow as you arrive, so a defensive driver eases off the gas and prepares to stop rather than racing through.
- When two cars reach a four-way stop at the same time and are side by side, defensive practice says you should generally do what to avoid a conflict?
- Insist on going first because you stopped harder
- Both proceed at once to clear the intersection faster
- Honk continuously until the other driver backs up
- Yield to the vehicle on your right and make eye contact before proceeding
Correct answer: Yield to the vehicle on your right and make eye contact before proceeding
Yielding to the vehicle on your right and making eye contact before proceeding is correct. At a four-way stop, the driver on the right has the right-of-way when arrivals are simultaneous, and confirming the other driver's intent prevents a collision.
- A defensive driver who notices a ball roll into the street from between parked cars should most reasonably anticipate what?
- Nothing further, since a ball is harmless
- That speeding up will clear the area before anyone appears
- A child may run out after it, so slow down and cover the brake
- That the parked cars will block any pedestrian
Correct answer: A child may run out after it, so slow down and cover the brake
Anticipating that a child may run out after it, so slowing down and covering the brake, is the defensive response. A ball entering the roadway is a classic warning that a child could follow into your path, so reducing speed and readiness to brake are essential.
- Driving downhill on a long, steep grade, the safest way to control your speed without overheating the brakes is to do what?
- Hold the brake pedal down firmly the entire way down
- Shift to a lower gear and let engine braking help slow the vehicle
- Shift into neutral and coast to save fuel
- Pump the accelerator to keep momentum steady
Correct answer: Shift to a lower gear and let engine braking help slow the vehicle
Shifting to a lower gear and letting engine braking help slow the vehicle is correct. On a long downgrade, riding the brakes can cause them to overheat and fade, while a lower gear uses engine resistance to control speed safely.
- While merging onto a freeway from an on-ramp, the defensive goal during acceleration is to do what before you reach the end of the ramp?
- Stop at the end of the ramp and wait for a complete opening
- Match the speed of freeway traffic and merge into a gap
- Enter the freeway well below traffic speed
- Force traffic in the through lane to brake for you
Correct answer: Match the speed of freeway traffic and merge into a gap
Matching the speed of freeway traffic and merging into a gap is correct. Using the acceleration lane to reach traffic speed lets you blend smoothly, whereas stopping or entering too slowly creates a dangerous speed difference with vehicles already on the freeway.
- When you must drive past a bicyclist sharing the road, defensive practice and many state laws call for you to do what?
- Pass as closely as possible to save time
- Honk to make the cyclist move onto the sidewalk
- Leave at least three feet of clearance and pass only when safe
- Speed up sharply right next to the cyclist
Correct answer: Leave at least three feet of clearance and pass only when safe
Leaving at least three feet of clearance and passing only when safe is correct. A wide buffer protects the cyclist from your vehicle's draft and from being struck if they swerve, and many states require roughly three feet when passing.
- A defensive driver approaching a railroad crossing with flashing red lights and a lowered gate should do what?
- Stop and wait until the lights stop and the gate fully rises
- Drive around the gate if no train is visible
- Proceed slowly because the gate is only a suggestion
- Stop on the tracks to get a better view
Correct answer: Stop and wait until the lights stop and the gate fully rises
Stopping and waiting until the lights stop and the gate fully rises is correct. Flashing lights and a lowered gate mean a train is approaching, and going around the gate is both illegal and deadly because a second train may follow.
- Why does a defensive driver leave extra space behind a motorcycle compared with following another car?
- Motorcycles can stop quickly and are easy to overlook, so more reaction space is needed
- Motorcycles always travel slower than cars
- Motorcycles cannot use their brakes
- The law forbids following any motorcycle
Correct answer: Motorcycles can stop quickly and are easy to overlook, so more reaction space is needed
The reason is that motorcycles can stop quickly and are easy to overlook, so more reaction space is needed. A motorcycle's short stopping distance and small visual profile mean a tailgating driver may not react in time, making a larger cushion important.
- When a traffic signal is completely dark because of a power outage, a defensive driver should treat the intersection as if it has what?
- Stop signs in all directions
- A permanent green for the main road
- No rules until power returns
- A flashing green for everyone
Correct answer: Stop signs in all directions
Treating it as if it has stop signs in all directions is correct. When signals go dark, drivers in every direction must stop and then proceed in turn, just as at a four-way stop, which keeps the intersection orderly and safe.
- On a road with a center two-way left-turn lane marked with yellow lines and turn arrows on both sides, a defensive driver should use that lane only to do what?
- Pass slower traffic on the left
- Drive in it for long distances to avoid congestion
- Make a U-turn at any point regardless of traffic
- Prepare for or complete a left turn, not to travel along it
Correct answer: Prepare for or complete a left turn, not to travel along it
Using it only to prepare for or complete a left turn, not to travel along it, is correct. The shared center turn lane is for entering and exiting left turns; driving along it or using it to pass invites a head-on conflict with someone turning from the opposite direction.
