The most effective thing you can do to reduce your risk of being injured or killed in a traffic crash is to:

  1. Wear your seat belt. ✓
  2. Limit your driving to weekdays.
  3. Stay in the right lane on multilane highways.
  4. Limit your driving to hours between 3:00 p.m. and 6:00 p.m.

Answer: A. Wear your seat belt.

Wear your seat belt every time you are in a vehicle.

Why this is the answer

The handbook says safety belts save lives and that you are far more likely to be killed in a crash if you are not wearing one. It also explains that a belt keeps you from being ejected, from being thrown against the steering wheel or other people, and behind the wheel so you can control the vehicle. Wearing both the lap and shoulder belt correctly every time is the safety action the passage supports for reducing crash injury or death risk.

Why the other answers are wrong

Remember it

Think belt first: lap across hips, shoulder across chest, every trip.
