Weather, Visibility & EmergenciesStandalone practice
It has not rained for three weeks. As you drive to work, a light drizzle begins. How should this change your driving?
Correct answer: Slow down and take extra care now, because the road is often slickest when rain begins.
Why
Oil, grease and dirt build up on the pavement in dry weather. The first rain loosens them and spreads a slippery film over the road before more rain washes it away. Increase your following distance, and brake, steer and speed up gently until you know how much grip you have.
