This free California DMV study guide teaches everything the tests on the written driver knowledge test, organized into the four content areas the exam draws from. Every fact here comes straight from the official .[1]
The written test is multiple choice and the passing standard is 80%. Drivers under 18 answer 46 questions and must get at least 38 correct; adults applying for an original license answer 36 questions, and renewing drivers answer the first 18 when a test is required.[6]It’s interactive, not a wall of text: every content area ends in a built-in checkpoint quiz, with hover-able glossary terms, worked scenarios, and concept questions throughout.
Studying for another state too? The road-safety basics carry over to our Texas DPS driving study guide, but the laws, limits, and point rules below are California-specific. Read this guide area by area, test yourself at each checkpoint, then round out your free prep with our practice questions and flashcards.

California uses different test forms by applicant type. A passing score is 80% — 38 of 46 for teens, about 29 of 36 for adults.
- Under 18 — provisional applicant (DL 5T)46 questions. You must answer at least 38 correctly (about 83%) to pass.
- Original adult license (DL 5)36 questions. A first-time adult applicant answers all 36; you must get about 80% correct.
- License renewal (DL 5)Renewing drivers answer only the first 18 of the 36 questions when a knowledge test is required.
- Three attemptsYou get three tries to pass the knowledge test on one application before you must reapply and pay again.

There is no penalty for guessing on the written test — answer every question. You have three attempts on one application.
The four content areas below mirror how the test is weighted. The biggest single area is Rules of the Road & Right-of-Way, followed by Signs, Signals & Markings — together more than two-thirds of the questions — so master those first:
Shares are based on the California knowledge-test blueprint and shift slightly between test forms.[6] This guide teaches all four areas as four study modules.
1 · Traffic Signs, Signals & Pavement Markings
About a third of the test. California uses standard sign shapes and colors, traffic-signal rules, and pavement markings to control the flow of traffic. Knowing them on sight is the fastest way to bank points.[5]
Sign Shapes & Colors
You can often read a California sign by its shape alone. An octagon is always a STOP; a triangle pointing down is YIELD; a pennant on the left warns no passing; a diamond warns of a hazard ahead.
| Shape / color | Meaning |
|---|---|
| Octagon (red) | STOP — come to a complete stop behind the limit line |
| Downward triangle (red/white) | YIELD — slow and give the right-of-way |
| Diamond (yellow/black) | Warning of a hazard or change ahead |
| Pennant (yellow) | No-passing zone (on the left side of the road) |
| Rectangle (white) | Regulatory — a law you must obey (speed limit, turns) |
| Orange diamond | Construction or maintenance zone ahead |
Traffic Signals & Arrows
A means stop like a STOP sign; a means slow down and proceed with caution. A steady yellow light means the signal is about to turn red — stop if you can do so safely. A red arrow means stop and stay stopped until a green light or arrow appears.
Pavement Markings & Curb Colors
separate traffic moving in opposite directions; white lines separate lanes moving the same way. A solid line means do not cross to pass; a broken line means passing is allowed when safe. You must stop behind the at a signal or stop sign. California’s five curb colors are heavily tested:
| Curb color | What you may do |
|---|---|
| Red | No stopping, standing, or parking |
| White | Stop only long enough to pick up or drop off passengers or mail |
| Green | Park for a limited time (shown on a sign or stenciled on the curb) |
| Yellow | Stop only to load/unload freight or passengers, within the posted time |
| Blue | Parking for a disabled person with a placard or plate only |
Checkpoint · Area 1 · Signs, Signals & Markings
Question 1 of 10
What does a RED curb mean in California?
2 · Rules of the Road & Right-of-Way
The largest area — roughly 17 of 46 questions.Right-of-way, speed limits, turns, lane use, and California’s licensing rules. Remember that is something you give, not take.[2]
Right-of-Way & Crosswalks
At a four-way stop, the first driver to stop goes first; if two arrive together, the driver on the right goes first. You must always yield to pedestrians in any , marked or unmarked, and never pass a vehicle stopped at a crosswalk.
At a four-way stop, the driver who arrives first goes first. If two arrive at the same time, the driver on the right (Car B) has the right-of-way. Always yield to pedestrians in any crosswalk, marked or not.
Speed Limits & the Basic Speed Law
California’s means you may never drive faster than is safe for conditions, whatever the sign says. Know the when none is posted:
| Location | Speed limit |
|---|---|
| Business or residential district | 25 mph |
| Near a school while children are present | 25 mph (or as posted) |
| Alleys | 15 mph |
| Blind intersections and blind railroad crossings | 15 mph |
| Two-lane undivided highway | 55 mph |
| Most freeways | 65 mph (70 mph where posted) |
Turns, Lanes & U-Turns
Signal at least 100 feet before a turn. You may make a U-turn across a single set of double yellow lines into a driveway or at an intersection where it is not prohibited, but never across a divided highway’s island or where a “No U-Turn” sign is posted. Enter and exit a carpool (HOV) lane only at the broken-line opening.
Licensing & Provisional Rules
A teen gets an at 15½, then a at 16 after driver education, training, and 50 hours of supervised practice. The first 12 months carry passenger and nighttime restrictions:
Source: California DMV. These graduated-licensing rules apply to drivers under 18.
Checkpoint · Area 2 · Rules of the Road & Right-of-Way
Question 1 of 10
Unless otherwise posted, what is the speed limit in a California business or residential district?
3 · Safe & Defensive Driving Practices
About 9 of 46 questions.Managing space, handling alcohol and drug laws, and avoiding distraction. This area is where California’s DUI limits and point system show up.[3]
Following Distance & Space
Keep a safe gap with the : when the vehicle ahead passes a fixed point, you should not reach it for at least three seconds. Add seconds in rain, fog, or darkness, when towing, or when someone tailgates you. Scan well ahead and keep an “out” — an escape path — at all times.
Alcohol, Drugs & the Point System
It is illegal to drive at a of 0.08% or higher (0.04% commercial, 0.01% under 21 under the ). By driving you give to a chemical test; refusing one suspends your license automatically.
Under California’s Zero Tolerance Law, a driver under 21 with a BAC of 0.01% or higher loses their driving privilege for one year. Refusing a chemical test carries its own automatic suspension.
Violations and at-fault collisions add points to your record under California’s . Reach the threshold and the DMV can suspend your license:
Hit any of these and the DMV can declare you a negligent operator (Vehicle Code §12810.5) — usually a one-year probation with a six-month suspension. Most violations add 1 point; a DUI, hit-and-run, or reckless driving adds 2 points.
Distraction & Cell Phones
Under California’s , adults may use a phone only hands-free and may not hold it; drivers under 18 may not use any wireless device except to call for emergency help. Texting is illegal for all drivers. Eating, grooming, and loud passengers are distractions the handbook warns against.
Checkpoint · Area 3 · Safe & Defensive Driving
Question 1 of 10
Under California's Basic Speed Law, how fast may you legally drive?
4 · Sharing the Road & Special Driving Situations
About 5 of 46 questions. Bicyclists, pedestrians, motorcycles, large trucks, emergency vehicles, and special conditions like fog, freeways, and railroad crossings.[2]
Bicyclists, Pedestrians & Motorcycles
California’s requires at least three feet of space when passing a bicyclist. Bicyclists may use a full lane and have the same rights as drivers.
Give motorcycles a full lane and extra space — they stop quickly and are easy to miss in a blind spot. Yield to pedestrians everywhere, and watch for the visually impaired using a white cane or a guide dog, who always have the right-of-way.
Emergency Vehicles & the Move Over Law
When an emergency vehicle approaches with a siren or flashing lights, pull to the right edge and stop until it passes; clear an intersection first if you are in one. California’s separately requires you to change lanes away from a stopped emergency, tow, or Caltrans vehicle, or slow down if you cannot move over.
Weather, Freeways & Railroad Crossings
In rain or fog, slow down, increase your following distance, and use low-beam headlights (high beams reflect off fog). California requires headlights on when weather requires wipers.
At a railroad crossing, never start across until you can clear it completely, and never drive around a lowered gate; watch for a second train. Merge onto a freeway at the speed of traffic using the acceleration lane.
Checkpoint · Area 4 · Sharing the Road & Special Situations
Question 1 of 10
In California, when passing a school bus, streetcar, or trolley that is stopped to load or unload passengers (where permitted), what is the maximum speed you may pass at?

California DMV Glossary
Quick definitions for the terms you’ll see most across the California written test:
- BAC
- Blood-alcohol concentration. It is illegal to drive at 0.08% or higher if 21+, 0.04% or higher in a commercial vehicle, and 0.01% or higher if under 21.
- Basic Speed Law
- California's rule that you may never drive faster than is safe for current conditions, no matter the posted limit. In rain, fog, or traffic, the safe speed can be well below the sign.
- Blind intersection
- An intersection with no stop signs or signals where your view is blocked. The speed limit is 15 mph unless otherwise posted.
- California Driver's Handbook
- The official study source for the California written knowledge test, published by the California DMV. Every test question is drawn from it.
- Crosswalk
- The part of a roadway set aside for pedestrians to cross. Every intersection has one, marked or not, and drivers must yield to pedestrians in it.
- DMV
- The California Department of Motor Vehicles, the state agency that licenses drivers, registers vehicles, and administers the written and drive tests.
- FasTrak / carpool (HOV) lane
- A lane reserved for high-occupancy vehicles during posted hours; entering or exiting only at the dashed (broken) line, not the double solid lines.
- Flashing red signal
- A signal that means the same as a STOP sign: stop completely, yield, and go only when safe.
- Flashing yellow signal
- A signal meaning slow down and proceed with caution; you need not stop, but watch for cross traffic.
- Hands-free law
- California's rule that adults may use a phone only in hands-free mode (no holding), and drivers under 18 may not use any wireless device except for emergencies.
- Implied consent
- By driving in California you automatically agree to take a chemical test (breath or blood) if lawfully arrested for DUI. Refusing brings an automatic license suspension.
- Instruction permit
- The learner's permit a teen gets at 15½ after passing the written test; it allows supervised practice driving with a licensed adult 25 or older.
- Limit line
- The wide white line painted across a lane at an intersection. You must stop behind it — not on or past it — at a stop sign or red light.
- Maximum speed limit
- Unless otherwise posted, 65 mph on most freeways (70 where posted), 55 mph on two-lane undivided highways, 25 mph in business/residential districts and near schools, and 15 mph in alleys and at blind intersections.
- Move Over law
- The requirement to move over a lane, or slow to a safe speed, when approaching a stopped emergency, tow, or Caltrans vehicle showing flashing lights.
- Negligent operator
- A driver who reaches 4 points in 12 months, 6 in 24 months, or 8 in 36 months (Vehicle Code §12810.5). The DMV can suspend or revoke a negligent operator's license.
- Point system
- California's record of at-fault collisions and violations. Most add 1 point; a DUI, hit-and-run, or reckless driving adds 2 points. Points trigger negligent-operator action.
- Provisional license
- The license issued to drivers under 18. For the first 12 months it restricts late-night driving and passengers under 20 unless a qualifying adult is present.
- Right-of-way
- The privilege of proceeding first at an intersection or crossing. In California, right-of-way is something you give, not take — you yield it to prevent a collision.
- Roundabout
- A circular intersection where traffic flows counterclockwise. Yield to traffic already in the circle and to pedestrians, then enter when there is a gap.
- Solid yellow line
- A pavement line separating traffic moving in opposite directions. A solid yellow line means do not cross to pass; a broken yellow line means passing is allowed when safe.
- Three-feet law
- California's requirement to leave at least three feet of space when passing a bicyclist traveling in the same direction.
- Three-second rule
- A way to measure safe following distance: you should be at least three seconds behind the vehicle ahead — more in poor conditions, at night, or when towing.
- Zero Tolerance Law
- California's rule making it illegal for a driver under 21 to drive with a BAC of 0.01% or higher, resulting in a one-year license suspension.

California DMV Study Guide FAQ
It depends on the applicant. Drivers under 18 take a 46-question test and must answer at least 38 correctly (about 83%). Adults applying for an original license take a 36-question test, and renewing drivers answer the first 18 of those questions when a test is required. The passing standard is 80%.
You need 80% correct. On the 46-question teen test that means 38 of 46 right; on the 36-question adult test it is about 29 of 36. There is no penalty for guessing, so answer every question. You get three attempts on one application before you must reapply.
The Basic Speed Law says you may never drive faster than is safe for current conditions, regardless of the posted limit. In rain, fog, heavy traffic, or near pedestrians the safe speed may be far below the sign — and you can be ticketed for driving the limit when it is unsafe. Unless posted otherwise, the limit is 25 mph in business and residential areas and 15 mph at blind intersections.
It is illegal to drive with a blood-alcohol concentration of 0.08% or higher if you are 21 or older, 0.04% or higher in a commercial vehicle, and 0.01% or higher if you are under 21 (the Zero Tolerance Law). By driving in California you give implied consent to a chemical test; refusing one brings an automatic license suspension.
The DMV adds points for at-fault collisions and violations — usually one point, but two for a DUI, hit-and-run, or reckless driving. You are presumed a negligent operator at 4 points in 12 months, 6 in 24 months, or 8 in 36 months (Vehicle Code §12810.5), which can lead to a probation and a six-month suspension. Most one-point violations stay on your record about 36 months.
For drivers under 18, the first 12 months of a provisional license bar driving between 11 p.m. and 5 a.m. and carrying passengers under 20, unless a parent/guardian or a California-licensed driver age 25 or older rides along. Medical, school, and employment exceptions require a signed note. Before the license you need a permit, driver education and training, and 50 hours of supervised practice.
California's three-feet law requires you to leave at least three feet of space between your vehicle and a bicyclist when passing in the same direction. If three feet is not possible, slow down and wait until you can pass safely with that clearance. Bicyclists have the same rights and responsibilities as drivers.
When you approach a stopped emergency vehicle, tow truck, or Caltrans vehicle displaying flashing amber or red-and-blue lights, you must move over a lane if you can do so safely, or slow to a safe speed. It protects the people working at the roadside on freeways and local roads alike.
Work through the four content areas in order — signs and signals, rules of the road and right-of-way, safe and defensive driving, and sharing the road. Take the checkpoint quiz after each module to find gaps, then drill them with our free practice test and flashcards, and review flagged sections before test day.
