Where is the Slippery When Wet Sign Commonly Found?
The slippery when wet road sign is placed in areas prone to hazardous conditions. Some common locations include:
1. Bridges and Overpasses
- Bridges and overpasses freeze faster than regular roads since they have air circulation underneath, making them more slippery in cold weather.

- Roads with sharp curves require caution, especially when wet, as tires can lose grip, increasing the risk of skidding.
3. Roads with Poor Drainage

3. Roads with Poor Drainage
- Areas where water accumulates easily create dangerous driving conditions and hydroplaning risks.
4. Shaded Areas
- Roads under trees or tunnels may stay damp longer, making them slippery even when other parts of the road are dry.
5. High-Traffic Intersections
- These areas experience frequent stopping and starting, which can lead to slick road conditions during rain.
