Warning, Construction & Information SignsStandalone practice
What hazard is indicated by the car-and-skid-marks warning sign shown?

Correct answer: The surface may be slippery, especially when wet.
Why
Expect reduced traction, particularly when the road is wet. Slow before reaching the hazardous area, allow more following space and avoid sudden braking or steering. The sign does not authorize testing grip with a sharp maneuver.
