On wet roads, how much should you reduce your speed?

Reducing your speed by one-third on wet roads is a critical safety measure. Wet conditions can significantly affect vehicle handling and stopping distances. When roads are wet, traction between the tires and the surface decreases. This reduction in grip means that vehicles require more time to respond to steering, acceleration, and braking inputs.

Reducing your speed by one-third helps to compensate for the risk of hydroplaning and allows more time to react to unexpected circumstances that can occur in slippery conditions. This reduction also increases your ability to maintain control of the vehicle and decreases stopping distances, making it a prudent choice for maintaining safety for both yourself and others on the road.
