What Does Double Flash Mean?
2 Answers
Double flash refers to the hazard warning lights. When you see the car in front turning on the double flash, it means the vehicle is in a non-operational condition, whether due to a breakdown or being stopped in a traffic accident while waiting for the police. This is to alert the vehicles behind that there is a stopped car ahead to avoid collisions. Traffic regulations state: In case of a breakdown or accident on the highway, the hazard warning lights must be turned on, and at night, the width marker lights and tail lights should also be activated simultaneously. When the light switch is turned to the first position, the small lights that illuminate at the front and rear are the width marker lights, indicating the vehicle's width to alert oncoming and following vehicles. Double flash lights are emergency lights; once activated, both small lights flash simultaneously to warn passing vehicles to be cautious. Double flash lights are used in situations like foggy or heavy rain conditions, vehicle breakdowns, or other emergencies.
The hazard warning lights, commonly known as 'double flashers,' are the emergency lights on our vehicles where all turn signals flash simultaneously. I call them 'life-saving lights,' as I've encountered several emergencies during my 30+ years of driving. For instance, when experiencing a sudden tire blowout or engine stall on the highway, I immediately press the hazard light button to alert following vehicles to slow down and avoid a collision. This practice is explicitly mandated in Chinese traffic regulations: if a vehicle breaks down and cannot move, the hazard lights must be activated. Avoid using them casually; reserve them only for emergency stops, accident scenes, or extremely poor visibility (e.g., heavy fog). Operation is simple—locate the red triangle button near the steering wheel and press it. Hazard lights not only enhance safety but also help prevent rear-end collisions. I recommend checking if the lights function properly before driving to avoid failure in critical moments. Cultivating this good habit ensures a more secure journey.
