- Three-second following rule
- Stay at least three seconds behind the vehicle ahead; add more in poor conditions.
- How to measure following distance
- Watch the vehicle ahead pass a fixed point, then count 'one-thousand-one, two, three' in seconds.
- Basic speed law
- Always drive at a speed that is reasonable and safe for conditions, even when below the posted limit.
- Posted speed limit
- The maximum legal speed for ideal conditions; you must slow below it when conditions require.
- Braking distance vs. speed
- When you double your speed, braking distance increases about four times.
- Total stopping distance
- Perception distance + reaction distance + braking distance — the full distance to stop after spotting a hazard.
- Reaction (perception-reaction) distance
- The distance traveled while you recognize a hazard and begin to press the brake.
- Following a motorcycle or large truck
- Increase your following distance beyond three seconds; they stop or behave differently than cars.
- Heavy load or trailer
- Increase following distance and slow earlier — the extra weight needs a longer distance to stop.
- Speed in a school zone
- Slow to the reduced limit and watch for children, especially when lights flash or children are present.
- Speed and side vision
- At higher speeds your field of side (peripheral) vision narrows, hiding hazards at the edges.
- Driving too fast for conditions
- You can be cited even under the posted limit if rain, fog, or traffic make your speed unsafe.
- Tailgating
- Following too closely; it removes your time to react and is a leading cause of rear-end crashes.
- Space cushion
- Open space kept on all sides of your vehicle so you have room to see, brake, steer, or escape.
- Sudden braking on standing water
- Avoid it — hard braking can trigger hydroplaning or a skid; ease off the gas instead.
- Worn tire tread and stopping
- Worn tread channels less water and increases hydroplaning and stopping distance on wet roads.
- Stopping distance on wet or icy roads
- It increases sharply; slow down and leave much more following distance.
- Speed entering a curve
- Slow down before the curve; braking while turning can break traction and cause a skid.
- Two-second rule (ideal conditions)
- Some manuals teach a two-second minimum in perfect conditions, but three seconds is the safer standard.
- Why slower is safer on the test
- The cautious, lower-risk choice is almost always the correct permit-test answer.
- Speed and crash severity
- Higher speed means a longer stopping distance and a much more severe crash if you hit something.
- Adjusting speed in heavy traffic
- Match the flow, keep your space cushion, and slow gradually rather than braking suddenly.
- Downhill speed control
- Shift to a lower gear so the engine helps slow you, instead of riding the brakes.
- Minimum following gap on the test
- At least three seconds — increase to four or more in rain, fog, snow, at night, or behind a motorcycle.
- School bus, flashing red lights + stop arm
- Drivers in both directions must stop, except oncoming traffic on a divided highway with a median.
- Painted center line vs. divided highway
- A painted line is not a median; you must still stop for a school bus on most roads.
- Sharing a lane with a motorcycle
- Never — give a motorcycle a full lane and extra following distance; look twice before turning or changing lanes.
- Passing a bicyclist
- Pass with plenty of room — often at least three feet by law — and treat the cyclist as a vehicle.
- Bicyclist's right-turn hand signal
- Right arm extended straight out means the cyclist intends to turn right.
- Bicyclist's left-turn hand signal
- Left arm extended straight out means the cyclist intends to turn left.
- Opening your door in bike traffic
- Check over your shoulder and mirrors for approaching bicyclists before opening the door.
- Large-truck blind spots ('No-Zones')
- If you cannot see the truck driver's mirror, the driver cannot see you; stay out of those areas.
- Large truck turning right
- It may swing left first; never try to squeeze up the right side.
- Slow-moving vehicle emblem
- An orange triangle (often with a flashing yellow light) marks a farm tractor or equipment moving under 25 mph.
- Stopped traffic at a crosswalk ahead
- Also stop — a pedestrian may be hidden in front of the stopped cars.
- Pedestrian at a roundabout crosswalk
- Yield to the pedestrian in the crosswalk on the approach or exit of the roundabout.
- Approaching emergency vehicle
- Pull to the right edge and stop until it passes; clear the intersection first if you are in one.
- Following an emergency vehicle
- Never follow closely or try to 'beat' a responding emergency vehicle through traffic.
- Passing a horse or animal on the road
- Slow down, give wide space, and avoid sudden noises or movements that could spook the animal.
- Sharing the road with pedestrians
- Yield at crosswalks and intersections; pedestrians may be hard to see at night or in bad weather.
- Blind pedestrian (cane or guide dog)
- Always yield the right-of-way; stop and let them cross safely.
- Bus or streetcar loading passengers
- Slow down and be ready to stop; people may step into the road around it.
- Driving in rain (headlights)
- Turn on low-beam headlights — high beams reflect off rain and reduce visibility.
- Driving in fog
- Slow down and use low beams; if it is too dense to see, pull completely off the road and wait.
- Snow at night (best lighting)
- Use low-beam headlights; high beams glare off the falling snow.
- Hydroplaning (what it is)
- Tires ride up on a film of water and lose contact with the road, cutting steering and braking.
- If you begin to hydroplane
- Ease off the accelerator, hold the wheel steady, and do not brake hard until traction returns.
- Preventing a skid on slick roads
- Make all speed, steering, and braking changes gradual and smooth, and slow down.
- Recovering from a skid
- Ease off the gas, do not slam the brakes, and steer in the direction you want the front to go.
- First rain after a dry spell
- Especially slippery — oil and dust on the road mix with water to form a greasy film.
- Icy curve, when to slow
- Slow down before the curve, not during it; braking while turning on ice can break traction.
- Heavy downpour, wipers can't keep up
- Pull off at a safe spot away from traffic and wait for the rain to ease.
- Animal in your lane at night
- Brake firmly while staying in your lane if you cannot stop in time; swerving can cause a worse crash.
- Night driving (overdriving headlights)
- Do not drive so fast that you cannot stop within the distance your headlights light up.
- Glare from oncoming high beams
- Look toward the right edge of your lane and slow down until the vehicle passes.
- Driving in strong wind
- Grip the wheel firmly and be ready for gusts, especially near trucks, bridges, and open areas.
- Brakes get wet after a puddle
- Test and dry them by gently pressing the brake pedal while driving slowly.
- Driving into sun glare
- Use your visor and sunglasses, slow down, and increase following distance.
- Black ice
- A nearly invisible ice layer, common on bridges and shaded spots; slow down and avoid sudden moves.
- Reduced traction (general rule)
- Whenever the road is wet, icy, or snowy, slow down and leave more space — your tires grip less.
- Legal BAC limit (21 and older)
- 0.08% blood alcohol concentration; at or above it, driving is illegal in every state.
- Commercial BAC limit
- 0.04% blood alcohol concentration for commercial drivers.
- Zero-tolerance law (under 21)
- It is illegal for a driver under 21 to drive with essentially any measurable alcohol in their system.
- How fast the body clears alcohol
- About one standard drink per hour — only time lowers your BAC.
- Coffee after drinking
- Does not reduce impairment or BAC; it may make you more awake but still impaired.
- Cold shower after drinking
- Does not lower blood alcohol level or reduce impairment.
- Body weight and BAC
- A lighter person reaches a higher BAC than a heavier person from the same number of drinks.
- Alcohol on an empty stomach
- Speeds how fast alcohol enters the blood, raising BAC faster.
- Implied consent law
- By driving, you agree to a chemical test if lawfully arrested for impaired driving; refusal means automatic suspension.
- Distracted driving (definition)
- Anything that takes your eyes, hands, or mind off driving — texting, phones, eating, or adjusting controls.
- Why texting is the worst distraction
- It takes your eyes, hands, and mind off driving all at once.
- Phone use for permit/teen drivers
- Many states ban all phone use, even hands-free, for permit and intermediate drivers.
- Drowsy driving
- Impairs you much like alcohol; the only real fix is to pull over and rest, not coffee or fresh air.
- Aggressive driving
- Give aggressive drivers room; never engage, retaliate, or make eye contact — let them pass.
- Prescription and over-the-counter drugs
- Can impair driving (drowsiness, slowed reactions); driving impaired by any drug is illegal.
- Marijuana and driving
- Impairs reaction time, judgment, and coordination; driving under its influence is illegal.
- Effects of alcohol on driving
- Slows reaction time, blurs vision, and impairs judgment and coordination.
- Open container law
- It is generally illegal to have an open alcohol container in the passenger area of a vehicle.
- Learner's permit
- The first license a new driver earns and Stage 1 of GDL; you may drive only with a licensed adult in the front seat.
- Graduated Driver Licensing (GDL)
- A staged system every state uses: learner's permit, then provisional/intermediate license, then full license.
- Provisional (intermediate) license
- The stage after the permit; you may drive alone but with limits, often on night driving and young passengers.
- Supervised driving requirement
- Permit holders must log a set number of practice hours with a licensed adult before the road test.
- Permit eligibility age
- Set by each state — commonly somewhere between 14 and 16; some states require driver's ed first.
- Vehicle registration
- The document and plates proving a vehicle is recorded with the state and allowed on public roads.
- Vehicle title
- Proves legal ownership of the vehicle — different from registration, which proves it is road-legal.
- Liability insurance
- Required in most states; it pays for injury and damage you cause to others in a crash.
- Collision coverage
- Pays to repair your own vehicle after a collision, regardless of who is at fault.
- Comprehensive coverage
- Pays for non-collision damage to your vehicle — theft, fire, vandalism, or weather.
- Driver point system
- Most states add demerit points to your record for violations; too many can suspend your license.
- Points expiring
- In most states, points gradually expire or are removed after a set period if you avoid new violations.
- Expired learner's permit
- If it expires before you get a full license, you generally must renew or reapply before driving again.
- License suspension vs. revocation
- Suspension is a temporary loss of driving privileges; revocation cancels the license entirely.
- Driving without a license
- Illegal and penalized; you must carry a valid license (or permit) whenever you drive.
- Driving without insurance
- Illegal in most states and can bring fines, license suspension, and registration loss.
- Failing the permit test
- You may retake it after a waiting period set by your state; fees and the wait vary.
- Carrying your license/permit
- You must have your valid license or permit with you and show it to police on request.
- Seat belt law
- Seat belts are required in nearly every state and are the most effective way to survive a crash.
- Child restraint requirement
- Children must ride in an age- and size-appropriate car seat or booster, usually in the back seat.
- Road (driving) test
- The behind-the-wheel exam after the permit stage; passing it moves you toward a provisional or full license.
- Reporting a crash
- Most states require you to stop, exchange information, help the injured, and report crashes above a damage threshold.
