When is a road most slippery during a rain shower?

  1. After one hour of heavy rain
  2. Just after the rain stops
  3. Just after the rain starts
  4. When the rain has cleaned the road
Show answer

Correct answer: Just after the rain starts

When rain starts, oil and dirt rise to the road surface and mix with water. Tires grip the road least at this time. Slow down in the first minutes.
