What hazard is indicated by the Slippery When Wet sign?

The hazard indicated by the Slippery When Wet sign primarily informs drivers that the road surface may be slippery when wet conditions prevail. This is particularly important because rain, snow, or other sources of moisture can reduce tire traction, increasing the likelihood of losing control of the vehicle. When drivers see this sign, they should be aware of the potential for skidding and decrease their speed to maintain control.

While other options may seem related, they do not directly address the specific risk associated with a wet road. For example, though icy conditions can contribute to a loss of control, the Slippery When Wet sign is broader and applicable to any wet surface, not just icy. The sign does not provide information about the date of road inspection or specifically indicate construction work, making those options irrelevant in this context. Thus, the emphasis on vehicle control highlights the sign's purpose to alert drivers to adjust their driving behavior appropriately when encountering wet conditions.
