1. A driver has a 14-year-old passenger riding without a seat belt. What is the legal consequence for the driver?
- No ticket, since only adults must buckle up
- A ticket applies only if the vehicle lacks a rear seat
- A ticket applies only if the passenger is under 8
- The driver can be ticketed for the unbelted passenger
Answer: D — The driver can be ticketed for the unbelted passenger
Any unbelted passenger under 16 can result in a ticket for the driver, regardless of the passenger's exact age below that threshold.
2. A passenger tucks the shoulder strap under their arm because it feels more comfortable that way. What is wrong with this?
- The strap must be worn across the shoulder and chest, not under the arm or behind the back
- Nothing, tucking it under the arm is an approved way to wear it
- The strap should instead be worn behind the back for comfort
- The lap belt, not the shoulder strap, needs adjusting in this case
Answer: A — The strap must be worn across the shoulder and chest, not under the arm or behind the back
The shoulder harness has to cross the shoulder and chest with little slack; wearing it under the arm defeats its protection.
3. A pregnant driver is positioning her lap belt before driving. Where should it sit?
- As low as possible under the abdomen
- Snug across the widest part of the belly
- Loosely across the hips to leave room for the bump
- Diagonally, replacing the shoulder strap entirely
Answer: A — As low as possible under the abdomen
For a pregnant driver, the lap belt should sit as low as possible under the abdomen, not across the belly.
4. A parent is buckling in their 18-month-old child, who weighs 22 pounds and is 2 feet 9 inches tall, for a drive in a car that has a passenger air bag. Where must the child ride?
- In the front seat, in a forward-facing restraint
- In the front seat, in a rear-facing restraint, since air bags add protection
- In a rear seat, using a booster with the standard safety belt
- In a rear-facing restraint, never in the front seat of a vehicle with an air bag
Answer: D — In a rear-facing restraint, never in the front seat of a vehicle with an air bag
A child under 2, under 40 pounds and under 3 feet 4 inches needs a rear-facing restraint and must never be placed in a front seat with an air bag.
5. A family driving with three children ages 4, 5, and 7, each requiring a child restraint, has a car with only two rear seating positions available. Where can the third child legally ride?
- In the front seat, without any restraint, since there is no room in back
- The car cannot be driven until a larger vehicle is found
- In the front seat, in an approved restraint, since every rear seat is already occupied by a child 7 or younger
- On an adult passenger's lap in the rear seat
Answer: C — In the front seat, in an approved restraint, since every rear seat is already occupied by a child 7 or younger
A child under 8 may ride in front in an approved restraint when every rear seat is already taken by children 7 or younger.
6. A short driver wants to sit as close to the steering wheel as possible for better pedal reach, but still needs to stay a safe distance from the air bag. What is the minimum distance from the air bag cover to the breastbone, measured from the center of the wheel?
- 6 inches
- 12 inches
- 8 inches
- 10 inches
Answer: D — 10 inches
Drivers should sit at least 10 inches from the air bag cover while still being able to control the car.
7. A child is seated directly next to a side air bag position. What risk does this create?
- No added risk if the child is properly belted
- Serious or fatal injury
- Risk only if the child is under age 2
- Minor bruising only, similar to any air bag deployment
Answer: B — Serious or fatal injury
A child seated next to a side air bag risks serious or fatal injury.
8. A parent needs to leave their 5-year-old alone in a parked car briefly. What is required to do this legally?
- Cracking a window is sufficient without any supervision
- Supervision by someone at least 12 years old
- Supervision by someone at least 10 years old
- It's illegal regardless of supervision for children 6 or younger
Answer: B — Supervision by someone at least 12 years old
Leaving a child six or younger alone in a vehicle is illegal unless a person at least 12 years old is supervising.
9. The posted speed limit on a highway is 65 mph, but dense fog cuts visibility to about 100 feet. What speed does the law require?
- 45 mph, the minimum safe highway speed
- 55 mph, the reduced-visibility limit
- Whatever speed is safe for the current conditions, even if well under 65 mph
- 65 mph, since that is the posted limit
Answer: C — Whatever speed is safe for the current conditions, even if well under 65 mph
The Basic Speed Law requires driving no faster than is safe for current conditions, regardless of the posted limit.
10. A driver is towing a trailer on a two-lane undivided highway with no posted speed limit signs. What is the maximum legal speed?
- 60 mph
- 55 mph
- 50 mph
- 65 mph
Answer: B — 55 mph
The maximum is 55 mph on a two-lane undivided highway and for vehicles towing trailers.
11. A driver spots an oncoming car and, at the same time, a bicyclist ahead on the right, with no room to safely pass both at once. What should the driver do?
- Speed up to clear the bicyclist before the oncoming car arrives
- Slow down and let the oncoming car pass first, then move left to give the bicyclist at least three feet
- Swerve left immediately to give the bicyclist three feet, ignoring the oncoming car
- Stop completely in the lane until both hazards clear
Answer: B — Slow down and let the oncoming car pass first, then move left to give the bicyclist at least three feet
Hazards should be taken one at a time: let the oncoming car pass, then move left to give the bicyclist at least three feet.
12. A front tire blows out while a driver is on the freeway. What is the correct response?
- Accelerate slightly to maintain stability
- Brake hard immediately to slow down before losing control
- Hold the wheel firmly, gradually ease off the accelerator, and correct the steering
- Snap your foot off the gas pedal right away
Answer: C — Hold the wheel firmly, gradually ease off the accelerator, and correct the steering
Sudden braking or snapping off the gas can cost control; the correct response is to hold the wheel, gradually release the accelerator, and steer to stabilize.
13. The right-side wheels of a car drop off the edge of the pavement onto the shoulder. What should the driver do?
- Accelerate to regain traction before steering back
- Yank the wheel sharply back onto the pavement right away
- Grip the wheel firmly, ease off the gas, brake gently, and steer back carefully
- Brake hard immediately, then steer back
Answer: C — Grip the wheel firmly, ease off the gas, brake gently, and steer back carefully
Yanking the wheel can throw the car into oncoming traffic; the safe method is to ease off the gas, brake gently, and steer back carefully.
14. During a long drive in extreme heat, the temperature gauge starts climbing. Which action helps prevent the engine from overheating?
- Use the defroster to increase airflow
- Increase speed to boost air cooling

- Right shoulder, exiting from the right side, away from traffic
- Right shoulder, exiting from the left side toward oncoming lanes
- Center median, exiting from either side
- Left shoulder, exiting from the left side
Answer: A — Right shoulder, exiting from the right side, away from traffic
A disabled vehicle should pull to the right shoulder, with occupants exiting on the right side away from traffic.
16. During commute hours, the CHP Freeway Service Patrol helps a stalled driver, but the car still won't start. Where do they tow it?
- Free to a CHP-approved location
- They do not offer towing, only roadside repairs
- To the driver's home
- To a private repair shop of the driver's choice
Answer: A — Free to a CHP-approved location
If the car won't start, the Freeway Service Patrol tows it free to a CHP-approved location, not to a private shop or home.
17. A car stalls on railroad tracks, and the crossing lights start flashing with a train approaching. What should the occupants do first?
- Try to push the car off the tracks before running
- Get out and run diagonally away from the tracks, toward the direction the train is coming from
- Stay in the car with seat belts on and call 911
- Get out and run straight away from the tracks in the direction the car is facing
Answer: B — Get out and run diagonally away from the tracks, toward the direction the train is coming from
With a train coming and lights flashing, occupants should get out at once and run diagonally away from the tracks toward the direction the train is coming from, then call 911.
18. An adult driver has a phone mounted hands-free on the dashboard. Which use of it while driving is permitted?

20. A driver starts the car inside a closed garage to let it warm up before leaving. What danger does this create?
- A buildup of odorless carbon monoxide gas
- A risk of the battery draining prematurely
- No added danger as long as the garage door will open before driving off
- A strong burning smell that signals the danger
Answer: A — A buildup of odorless carbon monoxide gas
Every gas engine produces carbon monoxide, a deadly odorless gas, so a car should never be started in a closed garage.
21. During a long drive, a driver begins to feel unusually tired, dizzy, and nauseated with a headache and ringing ears, without an obvious cause. What should the driver do?
- Open all the windows and keep driving at highway speed
- Ignore it, since these are normal signs of a long drive
- Have the exhaust system checked
- Turn up the air conditioning and continue
