Hazard lights should be used when pulling over to alert other vehicles in case of emergencies. The functions of hazard lights include: 1. Alerting other vehicles in case of breakdowns or accidents; 2. Preventing rear-end collisions when parked on the roadside. Situations requiring hazard light usage: 1. Vehicle breakdown or traffic accident on the road; 2. Parking on the roadside; 3. Driving in foggy conditions; 4. Both the towing vehicle and the towed vehicle should activate hazard lights when towing a disabled vehicle; 5. Temporary parking on the roadway; 6. Visibility less than 100 meters; 7. Transporting critically ill patients; 8. Reversing or making U-turns in complex road sections.









I've been driving for over a decade, and turning on hazard lights when pulling over is absolutely essential. It effectively alerts vehicles behind you that you're temporarily stopped, preventing rear-end collisions. Especially on highways or during rush hour, drivers behind can spot the flashing lights from a distance and slow down more easily. I've personally witnessed cars pulled over without hazard lights getting hit because the following vehicles didn't notice in time. Moreover, during rain, fog, or at night when visibility is poor, using hazard lights becomes even more critical, significantly improving safety. Developing this habit is simple, takes mere seconds, but greatly reduces risks. Remember, driving isn't just about you—it concerns the safety of everyone on the road.

As a novice driver, my instructor emphasized the importance of turning on hazard lights when pulling over. It's like adding a safety shield to your car, making other vehicles notice your parking in advance and reducing accidents. Especially on busy urban roads with heavy traffic, failing to use hazard lights can easily lead to being overlooked by fast-moving cars, even causing minor collisions. Every time I park by the roadside, I turn on the hazard lights first—it gives me peace of mind. Traffic rules also encourage this practice, as it not only protects yourself but also maintains overall road order. I believe new drivers should develop this habit from the start, making it an instinctive reaction over time.

Turning on the hazard lights is common sense when parking on the roadside, and I definitely think it's necessary. It immediately alerts other drivers that you're temporarily stopped, which is simple and effective. I usually drive to and from work, often pulling over to wait for someone or pick up something, and I always turn on the hazard lights, especially at night or during rainy days when visibility is poor. Safety comes first—if you don't use them, others might mistake your car as still moving, and if another vehicle comes speeding by, it could be disastrous. Since making this a habit, I've never had any minor collisions. The extra layer of protection is well worth it.

For the safety of my family, I always turn on the hazard lights when pulling over. This habit helps prevent accidents to the greatest extent, as it allows vehicles behind to react in advance. Once, when my child was sick, I hurriedly pulled over to buy medicine but forgot to turn on the hazard lights. As a result, a large truck almost sideswiped us, giving me a cold sweat. Since then, I remind myself every time, especially on highways or near schools where the risks are higher. Don't cut corners on safety details—turning on the hazard lights takes no time but can protect the people and things that matter most.

From a driving safety perspective, turning on hazard lights is mandatory when pulling over. Based on my research of numerous cases, it can reduce rear-end collision probability by up to 30%, potentially saving lives in critical moments. For instance, activating hazard lights during emergency stops or traffic congestion effectively alerts following vehicles to decelerate promptly. Failure to do so may lead to misjudgment by trailing vehicles, potentially causing chain collisions. Relevant traffic regulations also endorse this practice, and making it a habit can enhance overall driving etiquette. Remember, safety is the foundation of every parking maneuver.
