What is the distance for placing warning signs on ordinary roads?

[DanielaMarie]

On ordinary roads during the day, the warning triangle should be placed 50 meters behind the vehicle, and at night, it should be placed 150 meters behind the vehicle. Here are the details: 1. Ordinary roads: During the day, place the warning triangle 50 meters behind the vehicle; at night, place it 150 meters behind the vehicle. 2. Highways: On highways during the day, place the warning triangle 150 meters behind the vehicle; at night, place it 250 meters behind the vehicle. 3. Triangle placement: The warning sign is to alert that there is a faulty vehicle in the current lane, so the triangle must be placed in the lane where your vehicle is experiencing trouble—do not place it randomly. If a vehicle breaks down on a curve, the warning triangle should be placed before the curve to alert incoming vehicles to avoid the faulty car.
