How should you change your following distance when the road is wet?

Leave more space than on dry roads.

  1. Keep the same gap as on dry roads
  2. Leave more space than on dry roads ✔
  3. Follow closer to see their taillights

Why: Wet roads mean less grip and longer stops, so slow down and add space. Tennessee's manual says at least four seconds in bad weather. Check your state's number.

Huh, didn't know that: Roads can be most slippery when rain first starts, before oil and dust wash away.

The dad joke
Why do cars hate rainy days? The puddles always throw them off course!
