Weather, Visibility & EmergenciesStandalone practice
On a hot summer afternoon, rain begins to fall on a road that has been dry for weeks. When is the road likely to be the most slippery?
Correct answer: In the first few minutes, before the rain washes off the oil that the heat drew up
Why
Slow down at the first sign of rain; do not wait for the road to look wet. On a wet road, the manual advises a speed about 10 mph lower than normal. Brake, steer and accelerate gently, and keep more space ahead, because the tires grip less until the oil is washed away.
