Hazard lights can be used in the following situations: 1. When the vehicle breaks down and cannot operate normally, requiring towing; 2. When driving in rain, fog, sandstorms, or hail with visibility below 100 meters. Drivers should not use hazard lights unless facing danger or vehicle malfunction. Activating hazard lights means turning on the vehicle's alarm system, which serves to alert other drivers, allowing them to clearly see the trajectory of the vehicle in distress and avoid or reduce accidents. Vehicles specially permitted by traffic police departments can use hazard lights, such as when traffic police often require specific emergency rescue vehicles to turn on hazard lights before activating green wave escort for them.

I think the most common use of hazard lights is when there's a problem with the car. For example, if my car breaks down on the highway and I pull over to the side, I immediately turn on the hazard lights to alert drivers behind me to avoid a rear-end collision—this can be lifesaving. The same applies in severe weather. Last week, I encountered heavy rain where visibility was poor, and everyone slowed down and turned on their hazard lights to warn others, preventing accidents. When towing a trailer at low speeds, like hauling an RV for camping, using hazard lights lets drivers behind know not to crowd in. If you're stopped at an accident scene waiting for help, you should also turn on the hazard lights to warn other vehicles to detour. Legally, it's generally required to use hazard lights when stopped on the highway or moving slowly while towing—otherwise, you might get fined. Don’t misuse them in normal situations; only use them when there’s a real danger. Make it a habit to check that the lights work properly—safety first, as this can prevent many accidents.

As someone who frequently works on cars, I know the key to using hazard lights lies in emergency situations, mainly divided into several scenarios: when the vehicle breaks down and is parked on the roadside, hazard lights must be turned on to activate warning signals and prevent rear-end collisions; in poor weather conditions such as thick fog or heavy snow with low visibility, turning on the lights enhances warning; when towing equipment like a trailer at very low speeds, hazard lights should be used to alert following vehicles to slow down; at accident scenes while waiting for rescue, turning on the lights is a universal safety standard; there are also special circumstances like convoy movements where regulations sometimes require hazard lights, but they should not be misused. I regularly check the light switches, as it's crucial to ensure the electrical system is functioning properly to avoid failure at critical moments. Simply put, it's wise to use hazard lights only in emergencies.

When I first started driving, I was curious about when to use the hazard lights. The instructor taught me several situations: if the car breaks down and is stopped on the road, turn on the lights to avoid accidents; in bad weather like heavy rain or fog when visibility is poor, use them as a warning; when towing heavy loads and moving slowly, use the lights to alert other vehicles; if involved in an accident and stopped waiting for the police, turn on the hazard lights; on the highway, it's mandatory to use them when stopped, otherwise it's a violation. Remember to only turn them on when you need assistance, don't abuse them.
