,1. Question: It is illegal for a person 21 years of age or older to
drive with a blood alcohol concentration (BAC) that is ______ or
higher.
Answer: 0.08% — Eight-hundredths of one percent
• Expert Rationale: In California, 0.08% is the legal limit for drivers 21 and
older operating a regular passenger vehicle. Driving at or above this limit
significantly impairs motor skills, reaction times, and judgment, drastically
increasing the risk of a collision.
2. Question: You are driving on a freeway posted for 65 mph.
Traffic is heavy and moving at 35 mph. The best speed for your
vehicle is most likely:
Answer: 35 mph
• Expert Rationale: California’s "Basic Speed Law" dictates that you must
never drive faster than is safe for current conditions, regardless of the posted
speed limit. When traffic is heavy and moving at 35 mph, driving faster than the
flow of traffic creates a severe hazard.
3. Question: You must notify law enforcement and file a Report of
Traffic Accident Occurring in California (SR 1) with the DMV
when:
Answer: You have a collision and there is an injury or death
• Expert Rationale: State law requires a driver to submit an SR 1 report to the
DMV within 10 days if anyone is injured or killed in a crash, or if property damage
exceeds $1,000. This is an independent requirement from any report filed with
law enforcement.
4. Question: You must notify the DMV within 5 days if you:
Answer: Sell or transfer your vehicle
2
, • Expert Rationale: When you sell or transfer ownership of a vehicle, you are
legally obligated to notify the DMV within 5 days by submitting a Notice of
Transfer and Release of Liability (NRL). This protects you from liability for any
future traffic violations or accidents involving that vehicle.
5. Question: A pedestrian starts to cross the street after the
"Don't Walk" signal begins to flash. The pedestrian is in the
middle of the street when your signal light changes to green. You
should:
Answer: Wait until the pedestrian crosses the street before proceeding
• Expert Rationale: Pedestrian safety is a paramount responsibility. Even if
your light turns green or the pedestrian entered the crosswalk illegally, you must
yield the right-of-way to ensure they safely finish crossing the street.
6. Question: You exit a freeway on a ramp that curves downhill.
You should:
Answer: Slow to a safe speed before the curve
• Expert Rationale: Braking while actively turning on a downhill curve can
cause your vehicle to skid or lose traction. You should always reduce your speed
in the straightaway before entering the curve to maintain maximum control.
7. Question: A vehicle suddenly "cuts" in front of you creating a
hazard. Which of these actions should you take first?
Answer: Take your foot off the gas
• Expert Rationale: Easing off the accelerator immediately begins to restore a
safe following distance without the danger of slamming on the brakes, which
could cause a rear-end collision from vehicles behind you.

, 8. Question: You are approaching a green traffic light, but traffic
is blocking the intersection. What is the best thing to do?
Answer: Don't enter the intersection until you can get completely across
• Expert Rationale: Under California law, entering an intersection when you do
not have enough space to clear it completely is a traffic violation (often called
"blocking the box"). It prevents cross-traffic from moving when their light changes
to green.
9. Question: A safety zone is a specially marked area for
passengers to get on or off buses or trolleys. You may not drive
through a safety zone:
Answer: At any time or for any reason
• Expert Rationale: Safety zones are specifically designated areas on the
roadway to protect vulnerable pedestrians waiting for or exiting public transit.
Motor vehicles are strictly prohibited from driving through them under any
circumstances.
10. Question: A red arrow pointing to the right or left on a traffic
light means you may:
Answer: Not turn in that direction until the light turns green
• Expert Rationale: Unlike a solid red light (which allows for a turn after a
complete stop if it is safe and legal), a red arrow is an absolute prohibition. You
must remain completely stopped until the light transitions to a green arrow or
green light.
11. Question: Smoking inside a vehicle when a person younger
than 18 years of age is present is:
Answer: Illegal at all times
