When temporarily parking a vehicle in rainy weather, the hazard warning lights (also known as emergency flashers) should be activated. The relevant explanations are as follows: 1. Regulations on the use of hazard warning lights: Hazard warning lights, formally referred to as emergency flashers, are generally used when the vehicle experiences a malfunction, is in a dangerous situation, or needs to make a temporary stop on a main road. According to requirements, motor vehicles should only turn on the hazard warning flashers when driving in foggy conditions. 2. Relevant regulations: Article 58 of the "Regulations for the Implementation of the Road Traffic Safety Law of the People's Republic of China" stipulates: When driving at night without streetlights, under poor lighting conditions, or in low visibility conditions such as fog, rain, snow, dust, or hail, motor vehicles should turn on headlights, position lights, and tail lights. However, high beams should not be used when a following vehicle is driving close to the vehicle in front in the same direction. Motor vehicles driving in foggy conditions should turn on fog lights and hazard warning flashers.

I've been driving for twenty years and encountered countless situations where I had to pull over in the rain. Each time, I immediately turn on the hazard warning lights, commonly known as the double flashers, making both left and right turn signals blink simultaneously. Why do this? In rainy conditions with poor visibility, when parked on the roadside or emergency lane, other drivers might not see your car clearly. Activating the double flashers sends a warning light from afar, preventing rear-end collisions. I remember once during a heavy downpour on the highway, I paused for a minute without turning on the lights and was nearly hit by a truck—it was absolutely terrifying. Since then, I've made it a habit: never cutting corners when parking in the rain, always choosing a safe spot away from curves or waterlogged areas, ensuring safety comes first. Additionally, if the car breaks down, you can turn on the small lights or headlights along with the double flashers, but the double flashers remain the core protective tool.

During driving lessons, my instructor repeatedly emphasized activating hazard lights when parking in the rain. Now I follow this practice immediately whenever encountering such conditions. The reason is straightforward: rain reduces visibility, and the flashing hazard lights serve as a conspicuous warning to following vehicles, preventing potential collisions. As a novice, I've practiced parking in rainy conditions multiple times and clearly felt more at ease with the lights on. This isn't superstition but practical necessity – wet roads and reduced speed make other drivers prone to distraction. I also learned that hazard lights should only be used when stationary, such as while waiting or during breakdowns, not while driving to avoid confusing signals. Developing this habit has significantly improved my driving safety, along with regularly checking light functionality to prevent last-minute malfunctions from causing trouble.

From a safety perspective, using hazard warning lights, commonly known as double flashes, when parking in the rain can significantly improve vehicle visibility. Rain absorbs light, making the environment dim, and the yellow strobe of double flashes has strong penetration through rain and fog, helping distant drivers identify the parking position. Personally, I recommend also turning on small auxiliary lights to avoid relying solely on a single light source. The key is to ensure that the battery and lights are intact, with regular maintenance of the circuit to prevent moisture-induced short circuits. This practice originates from traffic regulations, reducing the risk of accidents by more than 50%, especially on highways where even brief parking poses a hazard. Simple steps can prevent major disasters.
