How long can the hazard lights be left on when parked?

[SanKevin]

Parking hazard lights can be left on for over ten hours, as the car battery will automatically recharge when the engine is running. Situations requiring the use of hazard lights: 1. Driving in foggy conditions—due to poor visibility, drivers should turn on both hazard lights and fog lights to alert passing vehicles and provide illumination; 2. In case of a breakdown or traffic accident on the road, hazard lights should be activated to warn other vehicles of potential hazards; 3. When towing a disabled vehicle, both the towing vehicle and the towed vehicle should turn on hazard warning lights to indicate their non-standard operating condition. The purpose of hazard lights is to alert other drivers in unexpected situations. Even when parked on the roadside, hazard lights should be turned on to prevent rear-end collisions.
