You are driving when it begins to rain. You should:

  1. Drive faster than surrounding traffic.
  2. Drive at the maximum posted speed limit.
  3. Slow down. ✓
  4. Drive closely behind the vehicle in front of you.

Answer: C. Slow down.

When it starts to rain, you should slow down.

Why this is the answer

The handbook says to slow down and leave more following distance when the road is wet. It explains that even a small amount of rain makes roads slippery, which makes the car harder to control. Slowing down helps you keep complete control of the situation. That is why slowing down is the right response once rain begins, rather than holding the maximum speed or crowding the car ahead.

Why the other answers are wrong

Remember it

Think of rain as a signal to back off the gas and drop back from the car ahead, not to keep pace.
