How far should the warning triangle be placed on expressways?

[MacHaven]

Conventional roads: 50 to 100 meters away, Expressways: 150 meters away. Introduction to warning triangles: The accurate name for the triangular warning sign is the motor vehicle warning triangle. The automotive warning triangle is a passive reflector made of plastic reflective material. Functions: When a driver encounters an unexpected breakdown requiring parking for repairs or an accident on the road, upon noticing a warning triangle ahead, they need to go through a process of discovery, clearly seeing the warning signal ahead, taking measures to brake, slow down, and yield. Utilizing the reflective properties of the warning triangle can alert other vehicles to take evasive action, thereby preventing secondary accidents.

On expressways, I personally think placing the warning triangle at least 150 meters away is the safest. Due to the high speeds on highways, drivers behind need sufficient reaction time. If placed too close, they might not have enough time to slow down before a collision. I remember once seeing an accident on the highway where the warning triangle was placed only 50 meters away, resulting in a secondary collision. When placing the triangle, choose a spot with good visibility, set it up firmly to prevent it from being blown over by the wind. It's best to first turn on the hazard lights to warn following vehicles, then start walking from behind the car to estimate the distance—an average adult step is about 0.7 meters, so 200 steps would roughly be the right distance. In poor weather conditions like fog, placing it 200 meters away is even safer. After all, safety comes first. Always check before each trip to ensure the warning triangle is in the car as a backup—this small item can be a lifesaver in critical moments.

I have extensive driving experience. When placing warning triangles on expressways, I usually set them 150 meters away. On highways, the minimum recommended distance is 150 meters because at 100 km/h, the braking distance can exceed 100 meters. Measuring the distance is simple - I often use my phone's GPS or count steps: starting from the rear of the vehicle, about 200 steps will get you there. Before placing the triangle, ensure safety by parking in the emergency lane with hazard lights on, then quickly position the triangle. Don't dawdle when placing it - expressway traffic moves fast, so efficiency is key. Remember to wear a reflective vest for visibility, and position the triangle directly facing the lane so approaching drivers can see it from afar. In bad weather, increase the distance appropriately - don't cut corners and risk disaster.

The standard distance for placing a warning triangle on an expressway is approximately 150 meters. This regulation is designed to reduce the risk of secondary accidents, as vehicles travel at high speeds on expressways, and 150 meters provides sufficient buffer time for following vehicles. When placing the triangle, first park the vehicle safely, turn on the hazard lights, then walk 150 meters from the rear of the vehicle to position the triangle. Important notes: Ensure the triangle is placed straight and not tilted, as this could affect visibility; it's best to place it outside the guardrail for personal safety. In heavy traffic, the distance can be slightly reduced but should not be less than 100 meters. Paying attention to these small details can prevent major problems.
