Warning, Construction & Information SignsStandalone practice
Rain starts to fall after several dry weeks. You see a yellow diamond sign that shows a car with two wavy tire tracks behind it. How should you drive in this area?
Correct answer: Slow down, and brake, steer and speed up gently.
Why
The Slippery When Wet sign marks pavement that becomes unusually slick when it is wet. The first rain after a dry period is a special risk, because the water mixes with oil and dirt on the road. On wet roads, slow down and brake earlier and more gently, because the tires can hydroplane and you need more distance to stop.
