What are the hazard warning lights on a car?

Hazard warning lights on a car are warning lights and hazard signal lights, which are the same type of light, referred to as hazard warning flashers. The hazard warning flasher is controlled by a button located in the middle of the front row, marked with a red triangle symbol, commonly known as the hazard lights or emergency flashers. It is a signal light used to alert other vehicles and pedestrians that the car is experiencing a special situation. Situations for using hazard warning lights on a car include: 1. When the vehicle malfunctions; 2. Breakdown on the highway; 3. When towing a faulty vehicle; 4. Sudden heavy rain while driving; 5. Transporting critically ill patients; 6. Emergency malfunction while driving; 7. Temporary parking on the road.
It saved my life last time driving on the highway in the rain! The hazard lights are actually that red triangle button on the dashboard—press it and all four turn signals will flash simultaneously. These are emergency signal lights: turn them on when your vehicle breaks down to warn cars behind to steer clear, or in heavy rain or thick fog when you can't see the road clearly. They must also be activated when towing, both on the towing and towed vehicles. But don’t press them randomly during regular traffic jams—cars behind won’t know if you’re stalled or just braking, which could actually cause a rear-end collision. Once when I had a flat tire on the highway, I set up the warning triangle and immediately turned on the hazard lights. A truck far behind changed lanes early—this thing is truly a lifesaver.
My dad, who has been driving for over thirty years, always mentions this. The hazard warning lights, commonly known as double flashers, have a control switch near the steering wheel with a prominent red triangle symbol. They share the same bulbs as regular turn signals, but when activated, all four corner lights flash at a high frequency simultaneously. The key point is the usage scenarios: you must turn them on when temporarily parked, in case of sudden breakdowns, or during extreme weather with visibility below 100 meters. Last time when I was driving my kid to school in heavy fog, I turned on the hazard lights, reduced speed to 30, and the vehicles behind kept a much longer distance, which greatly increased the sense of safety. Remember not to misuse them in non-emergency situations—using hazard lights while illegally parked will still get you a ticket.
