Observation, Speed & SpaceStandalone practice
A steady rain has made the road wet. Compared with a dry road, how should you set your following distance?
A follows B on a two-way road in steady rain. The pavement is wet.
Correct answer: Make the gap larger, because wet pavement can more than double your stopping distance.
Why
The two-second gap in the handbook is a minimum for good conditions at 40 mph or less. When the road is slippery or you cannot see well, use a larger gap and a lower speed. In heavy rain, many cars can start to hydroplane at 35 to 55 mph, so slowing down also helps the tires stay in contact with the road.
