Is placing a warning sign at 150 meters practical?
1 Answers
Placing a warning sign at 150 meters is a regulatory requirement. Here is an introduction to warning signs: 1. Overview: A warning sign is a standard emergency equipment on vehicles, typically triangular in shape, hence also known as a triangular warning sign, used in special circumstances. 2. Requirements: Warning signs must strictly comply with the "Road Traffic Safety Law," made of plastic reflective materials as passive reflectors. 3. Principle: The principle is that when a driver encounters a sudden traffic accident on the road, the reflective properties of the warning sign are used to alert other vehicles to avoid, thereby preventing secondary accidents.
