Review all 20 questions with answers
  1. You are about to reverse out of a driveway where children have been playing. What should you do before getting in?

    Correct answer: Walk around the car and check its surroundings, including low objects and children.

    A walk-around can reveal a child or small obstacle hidden from the driver's seat. Check before entering, then continue observing the area when you move; an earlier check does not guarantee it stays clear.

  2. Your wipers move normally, but they leave broad streaks across the windshield during a test. What does this tell you?

    Correct answer: Their cleaning performance needs attention before you rely on them in rain.

    The inspection includes whether the blades actually clear the glass, not simply whether they move. Poor wiping can obscure traffic and signs in rain; correct the problem before relying on them.

  3. While setting up the driver's seat, how should you position the head restraint?

    Correct answer: So it supports your head when you lean back.

    The guide directs you to check that the restraint supports the head. Treat its position as part of safe seating preparation, rather than lowering or removing it merely for convenience.

  4. You get into a borrowed car and find its seat position uncomfortable. When should you adjust it?

    Correct answer: Before you begin driving.

    Set the seat before driving so you can use the controls without changing position while moving. Familiarity with the route does not make an on-the-move seat adjustment a safe preparation method.

  5. NHTSA recommends at least how much space between the driver's breastbone and the steering-wheel air bag cover, while still comfortably reaching the pedals?

    Correct answer: 10 inches.

    Keep a minimum 10-inch space from the air bag cover to the breastbone and maintain proper seating posture. Moving back must still allow comfortable pedal reach; the measurement is not from the steering-wheel rim to the abdomen.

    Source: NHTSA; Air Bags; With advanced frontal air bags, do I still need to maintain 10 inches between the air bag cover and my breastbone?; official page read September 22, 2026. ↗

  6. Which arm position does the Louisiana guide recommend while holding the wheel in your normal driving position?

    Correct answer: Elbows slightly bent.

    Slightly bent elbows allow steering without overextending the arms and help reduce fatigue. Set the seat to allow control rather than stretching to reach the wheel.

  7. A passenger has pulled a door almost shut, but it has not latched fully. What should happen before you leave?

    Correct answer: Make sure the doors are fully closed and locked.

    The guide includes closed, locked doors in the pre-driving check. A door that appears nearly closed is not the same as one properly latched; address it before moving.

  8. You are carrying several loose items that will fit in the trunk. What preparation helps reduce their injury risk in a crash?

    Correct answer: Put them in the trunk instead of leaving them loose in the passenger area.

    Unsecured objects can move during a collision. The guide recommends putting loose items in the trunk when possible, rather than leaving them where occupants could be struck.

  9. During a pre-trip check, you find unusual wear in a seat belt and a buckle that does not latch properly. What is the appropriate response?

    Correct answer: Have the defective restraint corrected before relying on that seating position.

    The guide calls for checking belt wear and malfunctioning parts. A restraint that cannot latch properly is not made serviceable by an air bag or an improvised knot.

  10. The turn-signal bulbs operate, but their lenses are covered with mud. What should you do before setting off?

    Correct answer: Clean the lenses so the signals can be seen.

    Pre-driving checks include clean, intact signal and other lamp lenses. Electrical operation alone does not ensure another road user can see a light through accumulated dirt.

  11. You are unfamiliar with the driver-assistance features in a rental car. What is the best way to learn what its particular systems do before driving?

    Correct answer: Read the vehicle's owner's manual and learn the controls and limits.

    NHTSA notes that features and their names differ between vehicles. Learn whether a system warns, intervenes or provides continuous assistance; do not infer its capabilities from a marketing name.

  12. During ordinary forward driving, what safety benefit does the guide associate with hand-to-hand, or push-pull, steering?

    Correct answer: It avoids crossing the hands and arms over the steering-wheel air bag.

    The guide favors this technique for normal forward driving because the arms do not cross over the wheel. It does not remove the need to look ahead, steer smoothly or maintain control.

    Source: Louisiana Class D & E Driver's Guide linked by OMV (cover R08/25; internal revision markers vary); Hand-to-hand steering; printed page 49, physical PDF page 54; reviewed September 22, 2026. ↗

  13. You need a brief reach to operate the windshield-wiper control. What should your other hand do?

    Correct answer: Remain on the steering wheel to maintain control.

    Operating a necessary control may require a temporary one-hand reach. The other hand must continue steering; the guide does not treat this exception as permission to drive routinely without controlling the wheel.

    Source: Louisiana Class D & E Driver's Guide linked by OMV (cover R08/25; internal revision markers vary); One hand steering; printed page 49, physical PDF page 54; reviewed September 22, 2026. ↗

  14. The path is clear and you are moving away from a normal stop. How should you apply the accelerator?

    Correct answer: Progressively, for a smooth increase in speed.

    The guide recommends smooth acceleration, not stomping on the pedal or racing the engine. Gradual control helps you move predictably while maintaining an appropriate speed.

  15. Under normal level-road conditions, the guide suggests stopping far enough behind the car ahead that you can see what?

    Correct answer: The bottom of its tires.

    This is a practical stopped-spacing reference, not a moving following-distance rule. Leave room rather than crowding the rear bumper, and allow more space when conditions require it.

  16. In a vehicle with a conventional keyed ignition and steering lock, why must you avoid turning the key to LOCK while moving?

    Correct answer: The steering can lock and prevent you from controlling direction.

    The guide warns that selecting LOCK while the vehicle is moving can lock its steering. This question concerns that conventional keyed system, not a universal starting or shutdown procedure for every vehicle.

  17. A frontal air bag deployed in a crash. Before the vehicle is driven again, what does NHTSA say must happen to that air bag?

    Correct answer: It must be replaced at an authorized repair center.

    An air bag is a one-deployment device. NHTSA says to replace a used air bag at an authorized repair center before driving again; this does not replace the need to address any other crash damage.

  18. A car has forward collision warning, with no automatic braking intervention specified. What should you expect that warning feature to do?

    Correct answer: Alert you to a possible collision, leaving the driving response to you.

    Forward collision warning alerts the driver; by itself it does not brake or steer to avoid the crash. Do not confuse a warning feature with a separate intervention system.

  19. While reversing, you receive a rear cross-traffic warning even though the backup-camera image looks clear. What is a sensible interpretation?

    Correct answer: Traffic may be approaching outside the camera's displayed view.

    NHTSA explains that rear cross-traffic warnings can concern hazards outside the backup camera's view. A clear display is not proof that the whole area behind and beside the vehicle is clear.

  20. A Level 2 assistance system is steering and adjusting speed. Who must remain attentive and responsible for driving?

    Correct answer: The driver.

    Level 2 can assist with steering and acceleration or braking together, but the driver still monitors and remains responsible. Assistance is not permission to turn attention away from driving.
