Which light should be turned on promptly in case of a vehicle accident?

In the event of an accident, the hazard warning flashers should be activated. Here is relevant information: Hazard Warning Flashers: Hazard warning flashers, commonly referred to as 'double flashers' (a red triangle with an ! symbol button switch, colloquially known as hazard lights or emergency flashers), are signal lights used to alert other vehicles and pedestrians that the vehicle is experiencing a special situation. Brake Signal Lights: Brake signal lights, abbreviated as brake lights, commonly known as stop lamps, are warning lights used to alert following vehicles that the vehicle has applied braking measures. They are installed at the rear of the vehicle, are red in color, and automatically emit red light when the vehicle brakes as the circuit is connected. Given the critical importance of brake lights for vehicle safety, their brightness is significantly higher than that of tail lights, typically more than five times brighter. They can be clearly seen from a distance of over 100 meters during the day.

I remember a few years ago when I was rear-ended while driving, my car suddenly stopped, and I immediately turned on the hazard warning lights. The button is located in the center of the dashboard, marked with a red triangle. Pressing it causes all turn signals to flash simultaneously, creating a strong warning effect. Thankfully, I turned it on at that time, and the car behind noticed it immediately, slowed down, and changed lanes, avoiding a secondary collision. After activating the lights, I also placed a triangular warning sign 50 meters behind the car to ensure more people noticed the hazard. In any vehicle emergency, the first response should always be to turn on these lights—they instantly alert surrounding traffic and reduce collision risks. It’s also important to regularly check if the car’s warning lights are functioning properly, forming good habits just in case.

As someone who frequently deals with cars, I know that hazard warning lights should be activated immediately in case of an accident. Commonly known as the hazard lights or flashers, operating them is straightforward: locate the hazard button on the central control panel near the driver's seat—usually a red triangle or marked with an emergency symbol—and press it to make both front and rear lights flash. The purpose of these lights is to provide rapid warning in emergencies, preventing other vehicles from colliding due to lack of awareness. After turning on the hazard lights, pull over to a safe spot as much as possible, set up the warning triangle, and call for help if necessary—all these actions are centered around ensuring personal safety. Regularly pay attention to the lighting system while driving, and routinely check the button and bulb conditions to ensure they function effectively in unexpected situations.

When I was learning to drive, the instructor repeatedly emphasized that in case of an accident, the hazard warning lights must be turned on immediately. At first, I didn't know which button to press, but later I understood it was the control switch that makes all the car lights flash. The method is to find the flashing light icon button on the center console and press it gently to activate the flashing lights. This is particularly important because it warns vehicles behind to brake or avoid in time, reducing further trouble. Turning on the lights is the first step in the safety procedure, followed by stopping the car to stabilize the situation and seeking help from professionals. New drivers should practice the button positions more to avoid making mistakes in critical moments due to panic.
