How to adjust the high beam and low beam when driving?

Lighting is one of the important parts of automobile.

In ensuring the driver's safe driving

Play an irreplaceable role

Especially at night and in bad weather.

Its special function is becoming more and more obvious.

So how to use lighting correctly?

Corn, let me take you to know.

How to turn on the low beam or high beam?

Many people may find it incredible, but I don't know whether to turn on the high beam or not. But in reality, there are indeed some car owners who don't know that they turned on the high beam when driving.

In fact, it is easy to tell whether there is a high beam. Although the signs of high beam and low beam are very similar, there are still great differences. As shown in the above figure, the straight line on the left is the sign of high beam, and the icon on the right of diagonal line is the sign of low beam (some models will not have instrument indication when the low beam is turned on).

Why do you want to turn on and off the low beam when you meet at night?

Because the high beam angle is too high, it is easy to shake the eyes of the opposite car and the surrounding pedestrians, which affects their sight, thus bringing great safety hazards to driving. In addition, turning on the high beam while driving is also an impolite driving behavior, which is easy to cause dissatisfaction among other car owners.

The low beam lamp shines downward, and there is a very obvious cut-off line between 12- 18m in front of the vehicle (as shown in the figure). In the area 30-40m behind the cut-off line of light and shade, the objects with bright colors in this area can be distinguished by using the ground reflection light source, while the objects with dark colors still on the road are not easy to be detected. So be extra careful when driving at night.

When do I need to switch the low beam?

When the driver is driving, he needs to change the high beam into the low beam immediately if he meets the following conditions:

First, a car came across;

The second is to be close to the car in the same direction in front;

Third, when the road lighting is sufficient;

The fourth is when entering a busy street.

How to switch between low beam and high beam?

The change-over switch between high beam and low beam is usually on the left side of the steering wheel. As shown in the figure, when the switch is turned to the low beam position, the far and near beam lights flash when the pull rod is pushed inward, and the high beam lights are always on when it is pushed outward directly (some special models will be slightly different).

When do you need to use headlights?

1, when the line of sight is bad

Car headlights's biggest function is lighting, and you should turn on the headlights at night or in the case of low vision such as rain and fog. However, it should be noted that when there is a traffic meeting in foggy weather, please don't turn on the high beam.

2. When information needs to be transmitted (there is no legal provision, but it is established by convention):

Car headlights is not only used for lighting, but also serves as a language for communication between drivers. "The correct use of signal language can avoid some traffic accidents and play the role of" reminder "and" warning ".

High beam is very useful.

But abuse can easily lead to accidents.

1. The strong light of the high beam can cause instant blindness.

The luminous intensity of high beam is much higher than that of low beam.

Will make the driver and rider of the opposite vehicle

Pedestrian, etc. Blinded by bright light in an instant.

How dangerous is it?

Give me a chestnut.

2. The high beam will narrow the field of vision of the driver of the opposite vehicle.

The halo produced by the high beam will occupy a large part of people's vision and narrow the field of vision of the driver of the opposite vehicle. Experiments show that the high beam can "cover" people and things within 5 meters around. If someone is in this range, it is difficult to see the opposite vehicle clearly.

It's Murder!

3. Abuse of high beam can easily lead to "road rage"

If a grumpy driver is illuminated by the high beam of the opposite vehicle when overtaking, he may "answer blows with blows" and shine back at the other side with the high beam, leading to irrational and dangerous driving behavior.

4. Using the high beam when following the car will affect the driver in front.

When the high beam is used to follow the car at close range, a large area of anti-halo ring will appear in the rearview mirror of the front car, which makes the driver in front dazzled and it is difficult to observe the surrounding traffic environment.

thus it can be seen that

How dangerous is it to abuse high beam?

Ignoring this detail is fatal.

therefore

How to use the high beam?

When can't I use the high beam?

Driving at night, in the city road with good lighting conditions, it is forbidden to use high beam.

In principle, when crossing with motor vehicles, non-motor vehicles and pedestrians on roads without street lights and poor lighting, low beam lights should be used at a distance of 150 meters from oncoming vehicles or pedestrians.

At night, when there are no street lamps, poor lighting or low visibility such as fog, rain, snow and sand dust, the rear car can't use the high beam when driving near the car.

In case of fog, rainstorm, dust and other low visibility weather, high beam cannot be used. At this time, if the high beam is used, it is easy to form diffuse reflection, which seriously affects the driver's sight.

You can't use high beam when driving in expressway service area and toll station at night.

When should I use the high beam?

When driving on suburban roads and highways with no street lights and poor lighting at night, you can use high beam lights.

In some special circumstances, the low beam and the low beam can be used alternately to signal. For example, when overtaking at night, the left turn signal should be turned on in advance, and the low beam or horn should be used alternately; When passing through sharp bends, slopes, arch bridges, crosswalks or intersections without traffic lights at night, you should alternately use far and near lights to signal.

If you use the high beam for oncoming vehicles, you should first pay attention to whether you have turned on the high beam unintentionally, and at the same time, you can change the far and near beams to remind each other. If the other party ignores the reminder, move the line of sight to the right, slow down and drive to the right, and be careful to meet the car;

If the road ahead is a crossroads or a road with complicated road conditions, you should pull over and wait for the coming car to pass. If the rear car turns on the high beam, you can use the anti-glare rearview mirror, or you can lightly step on the brakes to remind the rear car.
