Identify one safe driving practice when it rains.

Reducing speed and increasing following distance is a crucial safe driving practice when it rains because wet road conditions can significantly affect vehicle handling and braking distances. Rain creates a slippery surface, which reduces tire traction, making it essential for drivers to decrease their speed. This reduction provides better control of the vehicle and allows more reaction time to unexpected situations, such as sudden stops or slippery patches.

Additionally, increasing following distance gives drivers a greater buffer zone. This extra space is vital when roads are wet, as vehicles require more distance to come to a complete stop safely. It also helps to ensure that in the event of hydroplaning or skidding, the driver has room to regain control without colliding with another vehicle.

In contrast, increasing speed in rainy conditions compromises safety, as it increases stopping time and decreases control. Using high beam headlights can create glare in rainy conditions and is generally discouraged, while continuing at normal speed neglects the fact that wet conditions require adjustments for safety.
