Stress can affect your driving by:

  1. Lowing your ability to focus on driving. ✓
  2. Decreasing your chances of an accident.
  3. Causing you to fall asleep at the wheel.
  4. Making you more aware of others around you.

Answer: A. Lowing your ability to focus on driving.

Stress lowers your ability to focus on driving.

Why this is the answer

The handbook says safe driving requires you to be fully engaged, with your hands on the wheel, eyes on the road, and mind on driving. It also states that anything affecting your physical or mental condition can impair your ability to drive. Stress is a mental condition, so it works against that full engagement and pulls your attention away from the road instead of keeping your mind on driving.

Why the other answers are wrong

Remember it

Before you drive, ask yourself whether something is keeping your mind on the road or pulling it away. Stress pulls it away.
