Question 1 of 7
  1. 1. You are adjusting the driver's seat in a car with a frontal air bag. What seating position does NHTSA recommend?
  2. 2. Your car is secured in a safe parking place. How can you check that its brake lights actually illuminate?
  3. 3. The wiper blades move but leave broad streaks that interfere with your view. What should you do before driving in rain?
  4. 4. You are loading passengers and heavy luggage for a trip. Which capacity limit should you respect?
  5. 5. Your tire-pressure warning light is off, and the tires look inflated. Does that remove the need for routine pressure checks?
  6. 6. A tire's tread has worn down until it is level with the built-in treadwear bars. What should you do?
  7. 7. A child's thick winter coat prevents the car-seat harness from fitting snugly. What should you do?

  1. You are adjusting the driver's seat in a car with a frontal air bag. What seating position does NHTSA recommend?

    Correct answer: At least 10 inches between your breastbone and the air-bag cover while comfortably reaching the pedals.

    Leave the recommended clearance while keeping proper posture and control of the pedals. An advanced air bag does not remove the need for a safe seating position or a safety belt.

  2. Your car is secured in a safe parking place. How can you check that its brake lights actually illuminate?

    Correct answer: Have a helper press the brake pedal while you observe the rear lights.

    Checking a light requires checking its operation, not just the appearance of its lens. The guide recommends a partner for observing the brake lights when the pedal is pressed.

  3. The wiper blades move but leave broad streaks that interfere with your view. What should you do before driving in rain?

    Correct answer: Replace the ineffective blades and make sure the windshield clears properly.

    Wiper movement alone is not enough. The guide calls for replacement when their condition reduces driving visibility, rather than waiting for a complete mechanical failure.

  4. You are loading passengers and heavy luggage for a trip. Which capacity limit should you respect?

    Correct answer: Both the vehicle's load limit and the tires' load limits.

    A load can fit inside a vehicle while still exceeding its safe capacity. Check the applicable limits rather than using available cabin space as a weight measure.

  5. Your tire-pressure warning light is off, and the tires look inflated. Does that remove the need for routine pressure checks?

    Correct answer: No; use a gauge for regular monthly checks.

    TPMS warns when a tire is significantly underinflated; it does not replace maintenance. Tires can be underinflated without looking flat, so NHTSA recommends monthly gauge checks.

  6. A tire's tread has worn down until it is level with the built-in treadwear bars. What should you do?

    Correct answer: Replace the tire rather than continue using its worn tread.

    The raised wear indicators show that the usable tread has worn down. NHTSA says tires are unsafe and should be replaced at 2/32 inch of tread; extra air cannot replace missing tread.

  7. A child's thick winter coat prevents the car-seat harness from fitting snugly. What should you do?

    Correct answer: Use thin warm layers, secure the harness, then add a blanket over it.

    Bulky coats can interfere with harness fit. NHTSA recommends thin warm layers, with a blanket or coat placed around the child after the harness is properly snug and secured.
