Background
At present, abusing high beam is bad traffic habit and road killer which are difficult to be radically treated. Data statistics show that the traffic accident rate at night is 1.5 times higher than that at daytime, and more than 60% of major traffic death accidents occur at night. The data related to police also show that 30-40% of traffic accidents at night are caused by abusing high beam and are in a rising trend. In one hundred degrees, when a search is performed using "high beam abuse" as a keyword, more than 70 pieces of content are involved in the high beam abuse. Therefore, abuse of high beam lamps becomes one of the important hidden dangers of causing road traffic accidents.
The phenomenon of high beam abuse generally exists in the world, but the consequences caused by different population structures, quantity, city scale and driving habits are different, the United states is taken as an example, people have developed good vehicle using methods and habits due to long-term vehicle using history of the people, high beam disorderly use only accounts for a very small part of the whole traffic violation, and when a police intercepts a motor vehicle, the more serious violation is usually found and evidence is obtained by adopting a recording and video mode.
The "road traffic safety law" of china makes clear rules for several situations where high beam lamps cannot be used during night driving, and high beam lamps cannot be used in the following situations:
1. when a vehicle meets a road without a central isolation facility or a central line, the high beam cannot be used within 150 meters from the vehicle coming in the opposite direction;
2. the high beam cannot be used when a narrow bridge or a narrow road without a central line or a non-motor vehicle meets the vehicle;
3. the high beam lamp cannot be used when the vehicle turns through the intersection controlled by the traffic signal;
4. when the motor vehicle runs under the conditions of no street lamp, poor illumination or low visibility in the presence of fog, rain, snow, sand dust and the like at night, and when a rear vehicle and a front vehicle which run in the same direction run in a short distance, the high beam lamp cannot be used;
5. when overtaking at night, the high beam and the low beam are used alternately to remind the front vehicle;
6. the high beam lamp is not suitable for urban areas with better illumination.
