Weather, Visibility & EmergenciesStandalone practice
It has just started to rain after a long dry spell. When is the road likely to be most slippery?
Correct answer: During the first half hour, while water mixes with oil and dust
Why
When rain starts, water lifts oil and dust from the pavement and makes a slippery film. Be most careful during the first half hour, double your following distance to about four seconds, and use low-beam headlights. In heavy rain, slow down to prevent hydroplaning.
