What is what appears on a warning sign that tells you the road is slippery when wet?

A warning sign that indicates the road is slippery when wet typically features a symbol of a car skidding or losing control on a slick surface. The sign may also include the words "SLIPPERY WHEN WET" in bold, capitalized letters to alert drivers of the potential hazard.

These signs are usually placed in areas where the road surface is prone to becoming slippery during rain, snow, or ice, such as on bridges, sharp curves, or areas with high humidity. The warning is meant to caution drivers to reduce their speed, increase following distance, and drive with extra care to avoid losing control of their vehicle on the slick surface.

It's important for drivers to take these warnings seriously and adjust their driving behavior accordingly to prevent accidents and ensure their safety on the road.
