When driving on the highway in rainy weather, you should turn on the headlights and fog lights. When visibility is less than 100 meters, you should also turn on the hazard warning lights (double flashing lights). Relevant information is as follows: 1. Wheels: The road surface is slippery on rainy days, and the car tires may experience hydroplaning. If the speed is too fast at this time, it may lead to brake failure or require a longer distance to stop the car. Therefore, the first thing to do when it rains is to reduce the speed. Rear fog lights should only be turned on when the rain is extremely heavy because the red tail lights themselves have excellent penetration power, and ordinary heavy rain cannot block their light. Rear fog lights are very bright and are designed to penetrate thick fog. Using them in ordinary rainy weather may dazzle the vehicles behind, and if the visibility of the drivers behind is affected, our own safety cannot be guaranteed. 2. Hazard warning lights: "Double flashing lights" are hazard warning lights, which every car has. The switch is two overlapping triangles. The misuse of double flashing lights is quite common in China, but they should only be used in very dangerous situations, such as when there is an accident ahead or when you need to temporarily stop on the main road. Generally, we should not use them during normal driving. Misusing double flashing lights may send wrong signals to surrounding vehicles, leading to dangerous situations.
I've been driving for many years, and choosing the right lights when driving on the highway in the rain is particularly important. I always turn on the low beams because rain scatters the light—using high beams makes it harder to see ahead and can easily dazzle oncoming drivers, which is very dangerous. If the rain is especially heavy or there's thick fog, I also turn on the front and rear fog lights. These lights have strong penetration and help the cars behind me see me clearly. Once, I didn’t turn on the fog lights while driving on the highway in the rain, and the car behind almost rear-ended me. Since then, I’ve been extra careful. Oh, and don’t forget to check if the window defogger and wipers are working properly to avoid blurred vision. Remember, turning on the lights isn’t just about helping you see the road—it’s more about making sure others can see you and reducing the risk of accidents. Safety first—if everyone drives this way, there will be fewer problems.
