The main reason for slowing down when driving a motor vehicle in rainy weather is to avoid accidents caused by slippery roads and poor visibility. Here are some precautions for driving in the rain: 1. Pay attention to controlling your speed and maintaining a safe distance from other vehicles. Avoid reckless lane changes to prevent accidents due to slippery roads and poor visibility. In the event of a traffic accident, move the vehicle to a location that does not obstruct traffic as quickly as possible for quick resolution to avoid leaving potential safety hazards. 2. Drive courteously and lawfully. When encountering traffic congestion, wait patiently in line, yield to others, and follow the instructions of traffic police. 3. Before traveling in rainy weather, check traffic conditions and weather information in advance. Pay attention to traffic prompts on outdoor information displays during your trip, choose the best route, and avoid waterlogged or congested sections.
In my years of sharing automotive knowledge, the primary reason for slowing down in rainy weather remains the insufficient tire grip caused by wet roads. When rainwater covers the road surface, friction is significantly reduced, increasing braking distance by over 40%. Especially at high speeds, water accumulation areas can easily lead to hydroplaning, causing the vehicle to lose control as if floating. To prevent accidents, driving at a reduced speed is a crucial step. I also recommend regularly checking tire tread depth and pressure, as these directly affect drainage performance. Reducing speed allows more reaction time to deal with pedestrians or obstacles—safety is always the core principle of driving.
Over the years of driving, I personally experienced the danger of nearly skidding off the road due to excessive speed in the rain. Since then, I never rush in rainy conditions. The essence of slowing down lies in reduced visibility and slippery roads—raindrops on the windshield obscure the actions of the car ahead, and water accumulation extends braking distance, increasing the risk of rear-end collisions even at slightly closer distances. I’ve developed the habit of slowing down early, turning on fog lights to enhance visibility, protecting both myself and others. This is wisdom gained from experience—safe driving is far more important than saving a few minutes.
