Which of the following is a safe practice when driving in rain?

Maintaining a safe following distance while driving in rain is crucial for safety. Wet roads can significantly reduce traction, making it easier for vehicles to lose control. By increasing the distance between your vehicle and the one in front of you, you provide yourself with a longer reaction time. This is especially important because stopping distances are longer on wet surfaces due to reduced friction. A greater following distance helps to ensure that if the car in front of you suddenly slows or stops, you have ample space to react safely.

In rainy conditions, other practices, such as excessively increasing your speed, using high beams, or turning off windshield wipers, can lead to dangerous situations, such as reduced visibility or the risk of losing control of your vehicle. Thus, maintaining a safe following distance is a prudent and effective strategy for safe driving in the rain.
