Question 6372
When driving on a wet roadway, the stopping distance will be...
- longer than when the roadway is dry.
- shorter than when the roadway is dry.
- the same as when the roadway is dry.
Show answer and explanation
Correct answer: longer than when the roadway is dry.
Stopping distance is the distance you travel while reacting plus the distance you travel while braking. On wet surfaces, tires have less grip and braking distance increases, up to twice as far as on dry surfaces, so the total stopping distance is also longer. That is why you should leave more space between you and the vehicle ahead in rain.
