Review all 16 questions with answers
  1. Before a trip, the brake pedal sinks to the floor and braking feels wrong. What should you do?

    Correct answer: Have the brakes checked before driving the vehicle.

    A suspected brake fault needs professional attention. Do not start a journey relying on brakes that are not working properly.

  2. What is a useful way to confirm that your brake lights, turn signals and other exterior lights work?

    Correct answer: Check their operation from outside the vehicle.

    Exterior observation confirms the actual lamps operate. A dashboard indicator alone does not check all the lights other road users depend on.

  3. The wipers leave large uncleared streaks during rain because the blades are worn. What maintenance is needed?

    Correct answer: Replace the blades that no longer clear the windshield.

    Wipers must clear the windshield well enough for safe visibility. Replace ineffective blades rather than waiting for total failure.

  4. You discover damage to the windshield. What does the handbook recommend?

    Correct answer: Have the damaged glass repaired or replaced.

    Damaged glass can be more vulnerable when struck or in a collision. Arrange an appropriate repair or replacement.

  5. Headlights produce strong glare through a film on the inside of your windshield. What should you do before the next drive?

    Correct answer: Clean both sides of the glass to restore clear visibility.

    A film on the inside also interferes with seeing. Keep the inside and outside of the windshield clean.

  6. Why should the heater and defroster be kept in working order?

    Correct answer: They help keep windows clear of fog and ice.

    A functioning defroster helps maintain visibility. It does not replace clearing exterior snow or checking the other windows.

  7. How can worn or bald tires affect your driving, especially on wet pavement?

    Correct answer: They can increase stopping distance and reduce control.

    Worn tires make stopping and turning more difficult, particularly in wet conditions, and can increase hydroplaning risk.

  8. Your car has its specified tire size. Where should you find the recommended inflation pressure?

    Correct answer: The vehicle's tire placard or owner's manual.

    Use the vehicle manufacturer's specification, not the tire's sidewall maximum.

  9. For a routine cold-tire pressure check, what does NHTSA mean by cold?

    Correct answer: The car has not been driven for at least three hours.

    Driving warms tires and changes pressure. A cold reading uses tires rested for at least three hours.

  10. Your vehicle carries a spare tire that has not been used. How should it be maintained?

    Correct answer: Include it in periodic pressure and condition checks.

    An unused spare still needs checking and maintenance so it is usable when needed. Follow its applicable pressure instructions.

  11. The steering becomes difficult to turn or fails to respond when you first move the wheel. What is the appropriate response?

    Correct answer: Have the steering checked by a mechanic.

    Faulty steering can prevent you from controlling the vehicle's direction. Have the cause checked rather than driving with an unresolved fault.

  12. In a car with a keyed steering lock, why must you avoid turning the ignition to LOCK while the vehicle is moving?

    Correct answer: It can lock the steering and cause loss of control.

    The LOCK position can engage the steering lock. Do not use it while the vehicle is in motion.

  13. Your car continues bouncing after a bump and feels harder to control. What should be checked?

    Correct answer: The shocks and other suspension components.

    Continued bouncing or poor control can indicate suspension trouble. Have a mechanic assess the system.

  14. You want to open the radiator to check coolant after driving. What is the safe approach?

    Correct answer: Wait until it is cool and follow the owner's instructions.

    Do not open a hot radiator. Let the system cool and follow the vehicle's instructions for checking coolant safely.

  15. A loose bottle is on the driver's floor before a trip. Why should you remove it?

    Correct answer: It could roll under a pedal and interfere with control.

    Keep the pedal area free of loose objects. Also secure items that could strike someone in a sudden stop or crash.

  16. What should guide routine maintenance for the particular vehicle you drive?

    Correct answer: The recommendations in that vehicle's owner's manual.

    Follow the manufacturer's maintenance recommendations. A vehicle in good working condition gives you more control and reduces avoidable breakdown risk.
