Slippery road ahead
A red triangle with a skidding car silhouette warns that the road ahead may be unusually slippery. Causes vary: spilled diesel, wet leaves, polished concrete, frost in shaded sections, or a section that frequently floods. Reduce speed, increase your following distance, and avoid heavy braking or sudden steering inputs.
