What is the appropriate action to take when driving in heavy rain?

When driving in heavy rain, reducing your speed and increasing the following distance is crucial for maintaining control and safety on the road. Rain can decrease visibility and create slippery conditions, increasing the stopping distance needed to react to hazards. By slowing down, you can better navigate potential dangers such as pools of water or other vehicles that may behave unexpectedly on wet surfaces. Increasing the following distance allows more time to react to sudden stops or maneuvers by other drivers, minimizing the risk of collisions.

The focus on speed reduction is particularly important because driving too fast in rainy conditions can lead to hydroplaning, where the tires lose contact with the road due to water buildup. By adhering to a slower pace, you're more likely to maintain traction and control over the vehicle. Furthermore, this practice helps create a safer driving environment for everyone on the road.
