Slippery When Wet Signs are MUTCD Compliant (MUTCD W8-5) and alert road-users to less traction in wet conditions. Slippery When Wet Signs are useful devices to help display official regulations and provide mandatory information to drivers and pedestrians on both private and public roadways.

Option
The Slippery When Wet (W8-5) sign may be used to warn of unexpected slippery conditions. Supplemental plaques with legends such as ICE, WHEN WET, STEEL DECK, or EXCESS OIL may be used with the W8-5 sign to indicate the reason that the slippery conditions might be present.
Guidance
When used, Surface Condition signs should be placed in advance of the beginning of the affected section, and additional signs should be placed at appropriate intervals along the road where the condition exists.
