Weather, Visibility & EmergenciesStandalone practice
Rain starts to fall on a hot summer afternoon after a long dry spell. Why should you take extra care during the first few minutes?
Correct answer: Oil from the hot asphalt mixes with rain and makes the road slick until it washes away.
Why
Rain, snow, and sleet all reduce the grip of your tires, so slow down at the first sign of any of them. On a wet road, the manual suggests driving about 10 mph slower than usual. Brake, steer, and speed up gently until you know how much grip the road has.
