Do I have to turn on the low beam when driving at high speed?

Do I have to turn on the low beam when driving at high speed? There are two kinds of isolation belts in the middle of the expressway. One is the grid type, which consists of hoods arranged at equal distances, and its characteristic is that it does not interfere with the horizontal field of vision. The field of vision also blocks the vertical light; The other is the green belt type, which generally places green plants in the middle of the road to block the light.

It can also beautify. Expressway is different from ordinary highway. For the sake of beauty and neatness, ordinary road plans should be as straight as possible. However, expressways may be limited by the environment or specially designed. There is basically no straight line extension. The road conditions are good, and the vehicle is controlled to turn or go up and down the slope.

Due to the maintenance or configuration of movable intersections on expressways, there is usually a short section without guardrails. In this case, in order not to affect the oncoming traffic, it is necessary to temporarily turn off the high beam. Although some sections have isolation belts, traffic lights will continue to pass, such as the upper and lower sections, which should be used in a civilized way at this time.

Ideally, in the traffic flow, the front car turns on the high beam and the rear car turns on the low beam, so that the road conditions can be seen in tandem without affecting the driver's line of sight. But as we all know, the quality of drivers in China is uneven, so it is difficult to have such an ideal situation.

During driving, it usually takes 2 seconds from finding road obstacles to preparing for braking, and then effectively slowing down the car; The reaction speed of driving during the day will be faster, but driving at night will generally be slower, and the actual standards are basically the same. The maximum speed limit of national and provincial roads is 80km/h, and the traveling distance per second is 22.22m.. ..

Fortunately, the effective braking distance will be shorter at low speed, and a safe distance of more than 80 meters is enough. Of course, the high beam is also used for lighting, so how can we use the high beam without affecting the car in front? The traffic of national highway, provincial highway and expressway must turn on the high beam.

On the road without lighting, the judgment criteria of road direction angle, height limit and road sign recognition are all judged by the reflection of road sign lights; Therefore, only the high beam is used. To effectively identify, this is the value of highlights. Driving on the highway is generally faster, and it is more dangerous if the driver is affected by the high beam.

So try to use the low beam and turn on the high beam when necessary, such as when looking at traffic signs and intersections. On national or provincial roads, high beam should be used when conditions permit, because there are motor vehicles, pedestrians and non-motor vehicles on the road, and the road surface may be in poor condition and need good lighting.

Although our country is comprehensively rectifying the behavior of turning on the lights, I haven't heard of any illegal warnings about turning on the lights illegally on expressways. However, for the sake of safety, try to use lights reasonably. When I see the distance between the taillights in front of me, I always use the low beam, because the front car is in front, so I can be sure that there is no problem on the road, but remember one thing.

The light brake light of the car is on, so you should brake lightly, just in case. Turn on the high beam when there is no car, or when you need to look at the road ahead. When there is a lot of traffic, Nana sauce hopes that everyone will not turn on the high beam at this time. It is really unfriendly to the driver in front. It will affect others' judgment on road conditions and cause safety hazards and dangers to themselves and others.

Do not turn on the high beam in bad weather, fog or heavy rain to avoid Tindal effect. Be sure to turn on the fog lights and danger warning lights at this time. It is also common that many drivers forget to turn off the high beam on the expressway. There is no timely change from rural highway to expressway.
