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

Reducing speed and increasing following distance during heavy rain is the best practice for driving because wet road surfaces can significantly decrease traction, making it easier to lose control of the vehicle. Slower speeds allow for better handling and more time to react to unexpected situations, such as sudden stops or obstacles. By increasing following distance, you create a buffer zone that gives you additional time to brake safely if the vehicle in front of you slows down or stops. This helps prevent collisions and enhances overall safety on slippery roads.

In contrast, increasing speed to stay ahead of traffic can be dangerous, as it reduces your control and reaction time. Using high beams during rain can further impair visibility because the light reflects off the water droplets, creating glare. Driving as you normally would ignores the special hazards that come with wet conditions, increasing the likelihood of accidents. Thus, the appropriate response to heavy rain is to drive more cautiously by reducing speed and increasing the distance between vehicles.
