Warning, Construction & Information SignsStandalone practice
Rain starts just as you pass a yellow diamond sign that shows a black car above two wavy tire tracks. Which change to your driving is correct?
Correct answer: Slow down, leave more space ahead, and brake and steer gently.
Why
Water reduces the grip between your tires and the road, and the loss is greater at higher speeds. On wet roads, the manual advises a speed 5 to 10 mph below the posted limit and a following distance of 5 to 6 seconds. Pennsylvania law requires a speed that is safe for the weather and a following distance that suits the road condition, even when you are under the limit.
