How many meters should the warning triangle be placed from the accident vehicle?

On highways, during the day, it should be placed at least 150 meters behind the vehicle, and at night, at least 250 meters behind. On regular roads, during the day, it should be placed at least 50 meters behind the vehicle, and at night, at least 150 meters behind. The purpose and precautions for placing the warning triangle are as follows: Purpose: The warning triangle, also known as a caution sign, is used when a vehicle breaks down on the road. Placing it at the appropriate distance behind the vehicle alerts approaching drivers that there is a stopped vehicle ahead, prompting them to slow down and pass safely. Alternatively, placing debris or branches between the vehicle and the warning triangle can prevent drivers from bypassing the sign and causing a rear-end collision. Precautions: The warning triangle should not be placed to the side or rear of the vehicle. In the event of an accident, no other items should be used as a substitute for the warning triangle. It should not be held by hand. Even if the warning triangle is placed, the vehicle's hazard lights must be turned on. After use, the warning triangle should be promptly retrieved and stored in its original place for quick access next time. 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 an accident on the road, obstructing traffic and making it difficult to move, the hazard warning lights must be turned on, and a warning sign should be placed 50 to 100 meters behind the vehicle. At night, the position lights and rear lights should also be turned on.
The distance to place the warning triangle from the accident vehicle is truly a critical safety issue. Having driven for many years and encountered several minor accidents, I always insist on placing it about 150 meters away on highways due to the high speeds – giving following vehicles enough time to react. On regular city roads, 50 meters is sufficient to ensure other drivers can spot it from afar. Never place it too close, as this significantly increases the risk of secondary collisions, especially in poor visibility conditions, where extending it to 80-100 meters is safer. Also, consider the lane position – place it slightly outward on the roadside without blocking your own safe standing area. Ultimately, this is about protecting yourself and others; there’s no room for carelessness.
Hey, I deal with this issue often, so let me tell you how to estimate it: After an accident on regular roads, I usually place the warning triangle 50 meters away. To be precise, that's about 60 steps, with each step calculated at 0.8 meters. On highways, you need to place it further, around 150 meters, which requires counting more steps for accuracy. Remember to check the recommendations on the warning triangle's packaging in your car—some brands have clear markings. Don't rely solely on visual estimation; it's easy to make mistakes, especially on curves or slopes where you should add extra distance. Safety first! Once you get into the habit, your driving mindset becomes much more stable.
From my understanding, the placement of warning triangles is regulated by law: on highways, they must be placed 150 meters away after an accident, which is a Chinese standard designed to ensure sufficient buffer space to prevent rear-end collisions. On regular roads, this distance can be reduced to 50 meters. There's scientific reasoning behind these rules, determined by visibility and traffic density. In practice, it's recommended to carry a measuring tape or use a mobile app to measure the distance accurately, rather than relying on estimation, as violating these regulations increases safety risks. The key is to adjust flexibly based on road conditions.
