Are hazard warning flashers and double flashers the same?

[Colin]

Hazard warning flashers and double flashers are the same. Their function is to serve as signal lights to alert vehicles and pedestrians that this vehicle is experiencing special circumstances. Their location is the red triangular button on the central control panel inside the vehicle. Situations requiring the use of hazard warning flashers: 1. When a breakdown or traffic accident occurs on the road; 2. When parking on the roadside; 3. When driving in foggy weather; 4. When towing a faulty motor vehicle, both the towing vehicle and the faulty vehicle should turn on the hazard warning flashers; 5. When temporarily stopping on the driving road; 6. When visibility is less than 100m; 7. When transporting critically ill patients; 8. When the vehicle is reversing or making a U-turn on complex road sections.
