How to use high beam correctly?

Use of high beam: Only when there is no other lighting equipment on the road and there is no vehicle on the opposite side can the high beam be used. The high beam is very bright. Abuse of high beam will seriously interfere with the other party's line of sight and even cause traffic accidents. Therefore, the high beam should be used correctly. The extended information is as follows: 1. On the road without central isolation facilities or centerline, high beam cannot be used within 0/50m from oncoming vehicles/kloc-. 2. When there is no central isolation facility or a narrow bridge or narrow road without a center line meets a non-motor vehicle, the high beam cannot be used. You can't use the high beam when you pass the intersection controlled by traffic lights. 4. At night, when there are no street lights, poor lighting or low visibility such as fog, rain, snow and dust, the rear car driving in the same direction cannot use the high beam when driving close to the front car. 5. When overtaking at night, you should alternately use the far and near lights to remind the car ahead. 6. It is not advisable to use high beam in well-lit urban areas.
