When driving in the rain, the driving resistance decreases. Resistance is the force generated by friction, which is determined by the coefficient of friction and the vehicle's own mass. During rainy conditions, the water on the road acts as a lubricant between the tires and the road surface, reducing the coefficient of friction, thereby decreasing driving resistance. Precautions for driving in the rain: 1. Control your speed: Since driving resistance decreases in the rain, driving too fast can easily cause skidding. Therefore, speed should be kept between 40-60 km/h, and you should drive slowly and cautiously. 2. Maintain distance: The braking distance on wet roads is three times that of normal roads. Keep a distance of 10-20 meters between vehicles and always monitor the distance to the cars in front and behind, increasing the safety margin. 3. Turn on the wipers promptly: Use your wipers to maintain good visibility in the rain. Additionally, turn on your low beams, fog lights, and marker lights, and be mindful of pedestrians, slowing down as needed.
