Warning, Construction & Information SignsStandalone practice
You drive on a highway and pass this yellow diamond sign. It shows a car with two wavy tire tracks behind it. What does the sign warn you about?
Correct answer: The road can become slippery when it is wet
Why
The sign marks a place where the surface loses grip in wet weather. When the road is wet, slow down, leave more space, and brake and steer gently, because a sudden move can start a skid. Washington law requires a speed that fits the conditions, and that can be below the posted limit.
