When the car breaks down, the warning triangle should be placed 150 meters away in the direction of oncoming traffic. Below is an introduction about the warning sign: 1. Introduction: The warning sign is a standard emergency equipment on cars, usually in the shape of a triangle, hence also known as a triangular warning sign. 2. Requirements: The warning sign must strictly comply with the "Road Traffic Safety Law" and be made of plastic reflective material as a passive reflector. 3. Principle: The principle is that when a driver encounters an unexpected traffic accident on the road, the reflective properties of the warning sign are used to alert other vehicles to avoid, thereby preventing secondary accidents.

The key to placing a triangle warning sign during a vehicle breakdown is ensuring safety alerts. On highways, I recommend placing the triangle sign at least 150 meters behind the vehicle, preferably in the middle of a straight section, avoiding curves or downhill areas where it might be hard for approaching drivers to see, which could lead to accidents. On city roads, placing it 50 meters away is sufficient, but always position it on the shoulder or sidewalk for stability. When placing it, don’t forget to turn on your hazard lights to increase visibility, and walk facing away from traffic, staying close to the edge for safety. After setting up the triangle sign, check that the reflective side faces oncoming traffic to enhance light reflection. Proper placement helps prevent rear-end collisions, protecting both you and others.

When placing a warning triangle after a car incident, I usually decide based on road conditions. On highways, place it over 100 meters behind the car, and on urban streets, about 50 meters away. Remember to choose a straight section of the road, not a curve, so the light reflects brightly. Be cautious of traffic when placing it, walk quickly along the roadside to set it up steadily. Always pair the triangle with hazard lights for maximum effectiveness. Once, I almost got hit in the rain because I placed it too close—now I always remind new drivers not to cut corners. Replace old triangles promptly to ensure good reflectivity. A few simple steps can make a big difference in safety.

Place the vehicle warning triangle farther away. On highways, place it 100 to 200 meters behind the vehicle; in urban areas, place it 50 meters away. Choose a flat, straight section of road to set it up, avoiding curves. After placing it, stand safely on the side. Avoid placing the triangle too close, as it can be dangerous. Use hazard lights in conjunction with the triangle.
