How to use lights in the new traffic law subject 1

Low beam lamp: used when driving in urban areas at night. On the one hand, the roads in the city are all illuminated by street lamps, so you don't need a high beam to explore the distant road surface, just look at the road surface in front of the car; On the other hand, the traffic in urban areas is large. If you turn on the high beam, it will not only dazzle other vehicles when passing, but also affect the sight of pedestrians on both sides of the road. In the case of heavy rain, heavy snow and other energy, not only the visibility is very low, but also the braking distance of vehicles will increase a lot, so it is best to turn on the low beam at this time to let other vehicles find themselves at the farthest distance.

High beam: When the high beam is turned on, a striking blue light signal will light up on the dashboard of the car as a reminder. It is more appropriate to use the high beam in the wild or on the road without street lights, but remember to switch back to the low beam when you encounter it, so as not to dazzle the other driver. If there are many vehicles on the road, it is best to switch to low beam mode when approaching the vehicle in front, so as to reduce the interference to the driver in front.

Many drivers like to honk when overtaking in expressway. In fact, because the engine noise and wind noise of vehicles are very loud when the speed is fast, it is difficult to hear the cars in front, especially those trucks. Therefore, when overtaking, it is best to press the horn a few times, move the lamppost up a few times, and use the high beam to remind the car in front.

Turn signal: The most basic function of turn signal is to signal other vehicles and passers-by to turn when the vehicle turns, so as to remind others to pay attention. Sometimes turn signals can also be used as lighting in narrow places, so that drivers can observe obstacles on both sides. When the turn signals on both sides are turned on at the same time, it plays the role of warning and width indication. When you turn left, turn around or pull over on the road without the central isolation belt, you should turn on the turn signal in advance and switch the headlights to the low beam, because if you turn on the high beam and turn on the turn signal, the pedestrians and vehicles on the other side will be dazzled by the headlights, and it is difficult to see the flashing of the turn signal.

Danger warning flash: We often say "double flash" and "double jump light". As a signal, it is mainly used to remind other vehicles and pedestrians that something special has happened in this car. So, under what circumstances do you use double jump lights? First, when there is a fault or traffic accident on the road, and second, when towing a faulty motor vehicle, both the tractor and the towed vehicle should turn on the hazard warning flash. Some friends like to turn on the double jump lights when they encounter meteorological conditions with poor visibility, such as fog, rain, snow, dust and hail, but at this time, the turn signal will lose the function of turning prompt, so it is best to use low beam lights and fog lights in this case, and try not to use double jump lights. If so, be sure to observe the situation before and after changing lanes. In addition, when a motor vehicle is driving on the road, it is not allowed to turn on the hazard warning flash at will.

Fog lamp: It is easy to understand from the name that fog lamp is a light signal used in foggy days. Fog lamps have stronger penetrating power in fog, and it is easier for vehicles or pedestrians to notice in advance. Some friends like to turn on fog lights and high beams when driving in foggy days, thinking that they can see farther, but in fact, this effect is not good. Because the illumination angle of high beam is easy to scatter light, its penetration is the worst in foggy days. At this time, turn on the front and rear fog lights, use the low beam lights, and slow down.

Back-up light: When reversing, there will be a white back-up light at the rear of the car. On the one hand, it can illuminate the roads and obstacles at the rear of the car, reduce the blind spots when reversing, and on the other hand, it is also a reminder to pedestrians behind. The reversing lights are all associated with reverse gear, so there is no need to operate them separately. However, if the reversing lamp fails, it should be repaired in time to avoid the danger of driving at night.
