What is the placement distance for the triangular warning sign?

[MacKendra]

According to regulations: On regular roads, in the event of a vehicle breakdown or traffic accident, the triangular warning sign should be placed 50 to 100 meters behind the vehicle. On highways, the warning sign must be placed at least 150 meters behind the vehicle, and this distance should be increased to 200 meters during rainy or foggy weather. Below is an introduction to the placement of the triangular warning sign: 1. In case of an accident on a curve, the triangular warning sign should be placed at the entrance of the curve; 2. If a vehicle breaks down on a slope and cannot be moved, the warning sign should be placed at the top or bottom of the slope.
