W8-5 Slippery When Wet Sign

Slippery When Wet

The Slippery When Wet road sign (W8-5) warns of unexpected slippery conditions ahead. The sign is often installed near bridges and overpasses. This is because bridges tend to be more slippery than the rest of the pavement during cold and wet weather conditions. In winter, bridges tend to freeze first and dry out last.

The sign is often mixed up with the Winding Road sign. Make sure you can tell them apart.

Beneath the sign you may see a supplemental plaques with legends such as ICE, WHEN WET, STEEL DECK, or EXCESS OIL. These indicate the reason for the slippery conditions.
