How many meters should the warning triangle be placed on the highway?

[KimberlyAnn]

The warning triangle should be set up 50-100 meters behind the vehicle, and the clearance lights and rear position lights should also be turned on at night. Below is relevant information about highway warning triangles: 1. Legal basis: According to Article 60 of the "Regulations for the Implementation of the Road Traffic Safety Law of the People's Republic of China," if a motor vehicle breaks down or is involved in a traffic accident on the road, obstructing traffic and making it difficult to move, the hazard warning lights should be activated as required, and a warning sign should be placed 50 to 100 meters behind the vehicle. At night, the clearance lights and rear position lights should also be turned on simultaneously. 2. Function: When a driver notices a warning triangle ahead, they need to go through a process of detection, clearly seeing the warning signal ahead, taking measures to brake, slow down, and yield. Taking a car traveling at 100 km/h as an example, it usually requires at least 10.8 seconds of reaction time or at least 350 meters of distance. This requires the warning triangle to have strong reflectivity so that the driver can see it immediately.
