In 2017, the Road Traffic Management Standardization Technical Committee of the Ministry of Public Security of the People's Republic of my country promulgated the national standard "Technical Conditions for Safety of Motor Vehicle Operation", requiring new vehicles to be equipped with a reflective vest from 2018. Afterward, the reflective vest will be the same as the motor vehicle warning triangle as an essential item for the car.
The main purpose of the promulgation of this regulation is to wear a reflective vest when a car breaks down at night, dusk, rain, and fog, or other unexpected situations when the visibility is relatively low. If the driver wants to get out of the car for vehicle inspection, etc., the driver can wear a reflective vest to improve The visibility of the driver at night to prevent secondary accidents.
Related experiments have also shown that in a dim environment, the visibility of people wearing black clothing is very low at 10 meters away, and those wearing red clothing and reflective clothing are clearly visible; at 20 meters away, black clothing is completely invisible. The visibility of the experimenter in red clothing is low; the reflective clothing is visible; 30 meters away, under the reflection of the car lights, only the reflective strips are still clearly visible.
Such an experiment can clearly reflect that reflective vests can effectively improve people’s visibility in dim environments and can alert other vehicle drivers to people in front of them. You can slow down in time. Use reflective vests to set up a warning sign to give People add a security guarantee.
