The so-called special weather refers to bad weather such as rain, snow and fog. The so-called special vehicle refers to vehicles with professional purposes such as mixer truck, truck crane, obstacle removal truck and dirt suction truck. How to use the lights in case of special weather?

一般遇到特殊天气时灯光使用过多的是双闪灯和雾灯，这两种灯光该如何使用？

In general, double flashing lights and fog lights are used too much in special weather. How should these two lights be used?

双闪灯又被叫做危险报警灯，它主要是在车辆出现故障、执行紧急任务或者是非常差的天气时使用的，使用双闪灯的主要目的就是告诉其他车辆我方车辆正处于紧急状态，要注意避让。

Double flashing lights, also known as hazard warning lights, are mainly used in case of vehicle failure, emergency tasks or very bad weather. The main purpose of using double flashing lights is to tell other vehicles that our vehicle is in a state of emergency and pay attention to avoidance.

雾灯：雾灯的主要特点是穿透力非常强，而且不会因为雾气产生漫反射反应，所以雾灯不仅能够提醒其他车辆注意我方的车辆，而且还能扩大我们在雾天行车的视野。

Fog lamp: the main feature of the fog lamp is that it has very strong penetration and will not produce diffuse reflection reaction due to fog. Therefore, the fog lamp can not only remind other vehicles to pay attention to our vehicles, but also expand our driving vision in foggy days.

在恶劣天气的灯光使用，在道路行驶中也是有规定的：

The use of lights in bad weather is also regulated during road driving:

1. 如果能见度低于200米，那就需要打开雾灯、近光灯、示廓灯和前后位灯，而且车速不能超过60km/h，同时还要与前车的车距保持在100米以上。

1. If the visibility is less than 200m, it is necessary to turn on the fog lights, low beam lights, position lights and front and rear position lights, and the speed shall not exceed 60km / h. at the same time, the distance from the front vehicle shall be kept at more than 100m.

2. 如果能见度低于100米，同样要开启雾灯、近光灯、示廓灯、前后位灯，还要开启双闪灯，车辆行驶速度不能超过40km/h，跟前车的车距要保持在50米以上的距离。

2. If the visibility is less than 100m, turn on the fog lights, low beam lights, clearance lights, front and rear position lights, as well as the double flashing lights. The driving speed of the vehicle shall not exceed 40km / h, and the distance from the vehicle in front shall be maintained at a distance of more than 50m.

3. 当能见度低于50米时，同样要打开雾灯、示廓灯、近光灯、前后位灯、双闪灯，此时车速需要控制在20km/h以内，而且要尽快从临近的出口驶出高速公路。

3. When the visibility is less than 50m, turn on the fog lights, clearance lights, low beam lights, front and rear position lights and double flashing lights. At this time, the speed needs to be controlled within 20km / h, and drive out of the expressway from the adjacent exit as soon as possible.

违规使用灯光也是要被罚款的，有些地方查的不严，不被罚款，但是各位车友不要存在侥幸心理，毕竟小心驾车行驶是才是道。

Illegal use of lights will also be fined. In some places, the investigation is not strict and will not be fined. However, motorists should not take chances. After all, driving carefully is the king.
