Weather, Visibility & EmergenciesStandalone practice
It has not rained for a week. Light rain started ten minutes ago. When is the road surface most likely to be slippery?
Correct answer: Now, during about the first half hour of rain
Why
Oil collects on the road in dry weather, and the first rain mixes with it to make a slippery film. When rain starts, slow down, increase your following distance, and do not brake hard or turn suddenly. Avoid ponded water when you can, because it can make the tires hydroplane.
