One of the rules of defensive driving is:

  1. Look straight ahead as you drive
  2. Stay alert and keep your eyes moving ✓
  3. Expect that other drivers will make up for your errors
  4. Be confident that you can avoid danger at the last minute

Answer: B. Stay alert and keep your eyes moving

One rule of defensive driving is to stay alert and keep your eyes moving.

Why this is the answer

The handbook's defensive driving chapter says traffic conditions change continuously, so you should always scan the road ahead and not fix your attention only on the road or the vehicle in front. It tells you to keep your eyes moving, watch what happens at the sides of the road, and check your mirrors every few seconds. That matches staying alert with moving eyes. The same passage also warns against assuming other drivers will act correctly, which is the opposite of expecting others to cover for your mistakes.

Why the other answers are wrong

Remember it

Think of your eyes as a searchlight that keeps sweeping: road ahead, sides, mirrors, repeat.
