What should drivers do during heavy rain to ensure safety?

During heavy rain, drivers should prioritize safety by reducing speed and increasing their following distance. Reduced visibility and slick road conditions significantly affect vehicle handling and stopping distances. By slowing down, drivers can better react to sudden changes, such as hydroplaning or the unexpected stops of vehicles ahead. Increasing following distance provides ample space to respond to potential hazards and allows additional time to brake safely without losing control of the vehicle.

Turning on high beams, as suggested in one of the options, can actually reduce visibility in rain due to the reflection of light off the water droplets. Changing lanes frequently can lead to erratic driving, making it challenging to predict vehicle movements, while driving in the center of the lane may not account for water accumulation, which often collects in the lanes. Therefore, adjusting speed and maintaining a safe distance are essential practices for navigating heavy rain conditions safely.
