During heavy rain, what is the best practice for driving?

Reducing speed and increasing following distance during heavy rain is the best practice for safe driving in these conditions. When roads are wet, traction can be significantly decreased, leading to a higher risk of skidding or hydroplaning. Lowering your speed gives you more time to react to any sudden changes or obstacles, as well as allowing your tires to maintain better contact with the road surface.

Increasing your following distance is equally important; it provides extra time and space to stop if the vehicle in front of you suddenly brakes. In wet conditions, stopping distances are longer, so having a greater buffer can help prevent rear-end collisions. Overall, this approach enhances safety for you and other road users during inclement weather.
