What does the car hazard warning light mean?

[StCecilia]

Car hazard warning lights (the triangular red button with an exclamation mark) are signal lights used to alert other vehicles and pedestrians that the car is experiencing special circumstances. When a vehicle breaks down on the road and cannot be moved to a safe area in time, the hazard warning lights should be activated immediately to alert passing vehicles and pedestrians for safety and to call for help. Situations that require turning on the hazard lights include: vehicle breakdown, breakdown on the highway, towing a faulty vehicle, sudden heavy rain while driving, transporting critically ill patients, emergency breakdown while driving, temporary parking on the road, vehicle accidents, and when performing special tasks.
