How can you improve visibility during heavy rain?

Using your windshield wipers and slowing down is the best way to improve visibility during heavy rain. Windshield wipers help clear water from your view, allowing for better sight of the road and surrounding vehicles. When rain is heavy, the road becomes slick and hazardous, and a reduced speed allows for greater control of the vehicle and the ability to react to sudden changes or obstacles.

Driving at a high speed would actually reduce visibility and increase the risk of losing control. Turning off your headlights is dangerous as it diminishes your visibility and makes your vehicle less visible to others. Opening your windows is not practical in heavy rain and does nothing to enhance visibility. Thus, using windshield wipers and slowing down strikes the right balance between maintaining control and ensuring visibility in poor weather conditions.
