What should you do if you experience heavy rain while driving?

Decreasing your speed when experiencing heavy rain is essential for maintaining safety on the road. Rain reduces visibility and can cause the road surface to be slick, increasing the risk of losing traction. By reducing speed, you give yourself more time to react to unforeseen obstacles or changes in traffic conditions.

Additionally, slower speeds help prevent hydroplaning, which occurs when a vehicle rides on top of a layer of water instead of the road. This situation can lead to a complete loss of control. Reducing speed also allows water to disperse more effectively under the tires, maintaining better contact with the road surface.

In heavy rain, it's generally advisable to drive at a speed that is safe for the current conditions, which may be significantly lower than the posted speed limit.
