What should you do when driving on a highway in heavy rain?

When driving on a highway in heavy rain, slowing down to avoid hydroplaning is essential. Hydroplaning occurs when a vehicle's tires lose contact with the road surface due to a layer of water, causing the driver to lose control. By reducing speed, you increase the tire's contact with the road, allowing for better traction and control. Slowing down also gives you more time to react to any hazards or sudden changes in visibility caused by the heavy rain.

In addition to enhancing control, decreasing your speed helps you maintain a safe distance from other vehicles, which is particularly important during inclement weather when stopping distances can be significantly longer. Therefore, adjusting your speed appropriately in such conditions is crucial for your safety and the safety of others on the road.
