Most Missed Questions on the California DMV Test
California has one of the hardest written tests in the country — and most first-timers miss questions on the same twelve topics. Not because the material is obscure, but because the handbook's specific numbers and distances get confused with rules from other states or outdated YouTube videos. Below is each trap, the correct handbook answer, and the number or rule to remember.
1. Parking on Hills — Wheel Direction
You are parking facing uphill next to a curb. Which way do you turn your front wheels?
A. Toward the curb (right)
B. Away from the curb (left, toward the center of the road)
C. Straight ahead
Why it's missed: The rule feels backwards. Uphill + curb = wheels away from curb. Then let the vehicle roll back gently so the tire rests against the curb. If brakes fail, the curb stops the roll. Downhill + curb = wheels toward the curb. No curb either direction = wheels toward the shoulder (right).
2. Signal Distance Before a Turn
How far before a turn must you signal?
A. 50 feet
B. At least 100 feet
C. 200 feet
Why it's missed: Different states use different signal distances. California's rule is at least 100 feet before a turn. On a freeway, signal at least five seconds before a lane change (roughly 400 feet at 55 mph).
3. Dimming High-Beam Headlights
How close to an oncoming vehicle must you dim your high-beam headlights?
A. Within 200 feet
B. Within 500 feet of an oncoming vehicle; within 300 feet of a vehicle you are following
C. Within 1,000 feet of any other vehicle
Why it's missed: Two different numbers — one for oncoming, one for following. Oncoming = 500 feet. Following = 300 feet. The 1,000-foot figure relates to when to use headlights (when it's too dark to see that far).
4. Under-21 BAC Limit
If you are under 21, what is the maximum legal blood alcohol concentration (BAC)?
A. 0.08%
B. 0.05%
C. Anything at or above 0.01% is illegal
Why it's missed: California's zero-tolerance limit under 21 is 0.01%, not 0.02% like most states. The same 0.01% limit also applies at any age if you are on DUI probation. Commercial drivers and drivers-for-hire: 0.04%.
5. Distance From a Fire Hydrant
You may not park within how many feet of a fire hydrant?
A. 10 feet
B. 15 feet
C. 25 feet
Why it's missed: Tempting to guess 10 or 20. California's rule is 15 feet from a fire hydrant or fire station driveway. Same 15-foot minimum applies to a crosswalk where a curb extension is present. For a regular crosswalk without a curb extension, it's 20 feet.
6. Following Distance Near an Emergency Vehicle
You may not follow a fire engine, ambulance, or other emergency vehicle with its siren or lights on within how many feet?
A. 100 feet
B. 200 feet
C. 300 feet
Why it's missed: The 300-foot rule is specific to active emergency vehicles. Driving to the scene of a fire, collision, or disaster can also be an arrestable offense because you're interfering with emergency personnel.
7. School Zone Speed Limit
The speed limit near a school while children are present is:
A. 25 mph within 500 feet of the school; some zones are 15 mph
B. 15 mph at all school zones
C. Whatever the posted limit is
Why it's missed: The default school-zone limit in California is 25 mph within 500 feet of a school while children are outside or crossing. Some zones post 15 mph. Watch for the 5-sided warning sign indicating a school is nearby.
8. Insurance Minimums (Updated)
What are California's minimum liability insurance coverage amounts?
A. 15 / 30 / 5
B. 30 / 60 / 15 ($30,000 single / $60,000 multiple / $15,000 property)
C. 25 / 50 / 10
Why it's missed: Most practice sites still list the old 15/30/5 minimums. California's current handbook (Rev. 6/2025) requires coverage of $30,000 single death/injury, $60,000 multiple persons, $15,000 property damage.
9. Passing a Bicyclist
When you cannot change lanes to pass a bicyclist, how much space must you leave between your vehicle and the bicyclist?
A. One foot
B. At least three feet
C. As long as there's enough room
Why it's missed: California's Three Feet for Safety rule is strict: at least three feet of clearance. If you can't give three feet, you may not pass until you can.
10. Safety Zone Passing Speed
When a bus, streetcar, or trolley is stopped at a safety zone or traffic light, you may pass at no more than:
A. 5 mph
B. 10 mph
C. 15 mph
Why it's missed: A rule people forget because safety zones are rare outside urban areas. 10 mph max when passing a stopped bus, streetcar, or trolley at a marked safety zone.
11. Address Change Deadline
How many days do you have to notify the DMV of a new address after you move?
A. 30 days
B. 14 days
C. 10 days
Why it's missed: California gives you 10 days. Separately, new California residents have 20 days to register an out-of-state vehicle after establishing residency or getting a job in the state.
12. Stopping for a Stalled Vehicle on Railroad Tracks
Your vehicle stalls on railroad tracks with a train approaching and warning lights flashing. What should you do?
A. Try to restart the vehicle
B. Immediately exit the vehicle and run away diagonally, in the direction the train is coming from
C. Stay in the vehicle with your seatbelt on
Why it's missed: The diagonal-toward-the-train direction is counterintuitive but correct — it keeps you clear of the debris field when the train strikes your vehicle. Run diagonally, toward the oncoming train, then call 911.
Why These Twelve?
These topics show up repeatedly in test-taker reports because each one has a specific number or specific direction that differs from drivers' intuition or from the rules in other states. The California handbook is unusually precise about these distances — they are not approximations. On the test, the distractors are usually numbers that sound plausible (10 feet vs 15 feet, 100 feet vs 300 feet). If you memorize the exact figure from the handbook, you'll beat every version of these trap questions.
