On a wet road, how much gap should you leave from the vehicle in front compared with dry conditions?
Answer and explanation
Correct answer: C. At least double
- Step 1: Wet roads reduce grip and so increase braking distance. Step 2. The Highway Code says to at least double the gap, giving four seconds. Answer: At least double. Why not the others: Keeping the same gap or reducing it leaves you without enough room to stop.
