California DMV practice test, with the answers explained

Every question below comes from the official California Driver's Handbook (DL 600) — the same document the DMV writes the real test from. Answer one and you get the reason, not just a tick or a cross.

Start here

No sign-up, no timer. Pick an answer and see why it is right.

  1. 1.If you are under 18 and turn 18 before 6 months with a permit, you:

    Why

    The six-month permit holding period applies only while you are under 18. Turning 18 satisfies it. (Handbook, Section 2.)

  2. 2.For a vanpool vehicle carrying 12 people, which license is appropriate with some conditions?

    Why

    A vanpool designed for 10 to 15 people is within Class C, with conditions attached. (dmv.ca.gov/dl — Section 1 of the handbook refers you there for the vehicles a Class C covers.)

  3. 3.If you are under 21 and are found in possession of alcohol as a passenger at a party, what may the court do?

    Why

    Under-21 alcohol offenses do not have to involve a vehicle at all. The court can still order DMV to suspend or delay your license.

  4. 4.If you fail the driving test, how soon can you retake it?

    Why

    There is a waiting period before a retest — minors must wait 14 days, not counting the day of the failure. (Handbook, Section 3.)

  5. 5.What is the DMV’s role if your insurance lapses?

    Why

    Insurers report lapses to DMV directly, and DMV can suspend the vehicle's registration as a result.

  6. 6.Before getting a driver's license in California you must pass:

    Why

    Both tests are required, and both are based on the information in the handbook. (Section 1.)

  7. 7.If your vehicle is hit by a strong gust of wind, having reduced your speed gives you:

    Why

    Reducing speed is about control and reaction time when a gust arrives. (Section 8, High Winds.)

  8. 8.If you are under 18, how long must you hold a permit before taking the driving test?

    Why

    Under 18 you must hold the permit at least six months (or turn 18) before the drive test can be scheduled. (Handbook, Section 2.)

  9. 9.Why should you NOT pump ABS brakes?

    Why

    ABS already pulses the brakes many times a second. Pumping interrupts it and lengthens your stopping distance. (Handbook, Section 8.)

  10. 10.If a police officer suspects you are impaired by drugs, they may:

    Why

    Officers may require a blood or urine test for drugs, even if you already passed a breath test — breath testing does not detect drugs.

  11. 11.During a traffic stop, passengers should:

    Why

    Passengers should stay quiet with their hands in view. Sudden movements from anyone in the car raise the tension of the stop.

  12. 12.A single solid white line marks:

    Why

    Single solid white lines separate lanes travelling the same way. Yellow is what separates opposing directions. (Section 6, Lane Markings.)

What the DMV actually asks of you

How many times can you take the California DMV written test?
Three. The handbook says you are allowed three attempts to pass before you must reapply — which means paying the application fee again and starting over.
How long do you have to wait to retake the DMV written test?
If you are under 18, seven days, not counting the day you failed. The handbook sets that waiting period for minors specifically, so it is worth checking your own case rather than assuming it applies to everyone.
Can you use the handbook during the knowledge test?
No. The handbook is explicit: you are not allowed to use any testing aids during knowledge tests, including a copy of the California Driver's Handbook or a cell phone.
What do you need to get an instruction permit under 18?
You must be at least 15½ years old, complete a driver education program, and have a parent or guardian sign to approve the application and accept financial responsibility. If your parents share joint custody, both must sign.
How long must you hold the permit before the driving test?
At least six months — or until you turn 18. You also have to prove you completed driver education and driver training, and practise for at least 50 hours with a California-licensed driver who is 25 or older. Ten of those hours must be at night.
What format does this practice test use?
The one a first-time adult applicant sits: 36 questions with 6 mistakes allowed, an 83% pass mark. Renewals answer only the first 18, with 3 allowed, and under-18 applicants take a longer form of 46 questions with 8 allowed — all three land on the same ~83% standard. The 1,980 questions in the bank all come from the official handbook, and every one of them explains its answer.

Where signs come in

Signs are where most people lose points, because reading them is a skill rather than a fact to memorize. There are 1044 of them in California, sorted here by the MUTCD series the road itself uses.
