I went out this morning and saw this:
Winter is the season when fog occurs most frequently. The temperature is low in winter, and water vapor in the air condenses to form fog.
Driving in foggy weather with low visibility and unclear sight
Driving friends, please pay attention.
At this time, you need to turn on the "fog lights"
What are fog lights
Car fog lights are installed on the front and rear of the car and are used to illuminate the road and provide safety warnings when driving in rainy and foggy weather, improving the visibility of the driver and surrounding traffic participants.
In low visibility conditions, the visibility of a vehicle is an important indicator for determining vehicle safety.
In layman's terms, in rainy and foggy weather, fog lights illuminate brighter and farther, making your car more likely to be noticed by other drivers, thereby avoiding a crash.
Anti-fog lights are divided into front fog lights and rear fog lights. The front fog lights are generally bright yellow, and the rear fog lights are red. Because anti-fog lights have high brightness and strong penetration, they will not cause diffuse reflection due to fog, so correct use can effectively prevent accidents. In foggy weather, front and rear fog lights are usually used together.
Front fog lights
On the left are three diagonal lines, crossed by a curved line, and on the right is a semi-oval shape.
Rear fog lamps
On the left is a semi-elliptical figure, on the right are three horizontal lines crossed by a curved line.
According to a survey by Chang'an University, although fog lights have the best penetration effect, in actual situations, the opening rate of fog lights is the lowest.
This shows that many car owners know the importance of fog lights in theory, but do not use them in practice.
When do the fog lights turn on?
According to Article 81 of the "Regulations for the Implementation of the Road Traffic Safety Law": When visibility is less than 200 meters in rainy and foggy days, motor vehicles should turn on their fog lights.
Under normal weather, turning on fog lights will interfere with the vision of other vehicles.
In good visibility conditions, fog lights can become very glaring.
Therefore, traffic regulations in many countries clearly stipulate that vehicles are prohibited from turning on fog lights when visibility is good.
How to turn on the fog lights?
For most models currently on sale, the fog light switch is located behind or on the left side of the steering wheel, and there will be obvious signs.
There are two main styles of fog light switches, push-button type and knob type. Different car manufacturers will have their own customary ways to turn on fog lights.
1. Push-button switch
It is more common on American brands such as General Motors and Ford.
It is characterized by easy operation and the corresponding functions can be realized with just one click.
2. Knob switch
Knob-type fog light switches are also divided into two styles:
One is integrated on the left shift lever (turn signal lever), which is common in self-owned brand and Japanese brand models;
The other is independently set in the left area of the center console in the form of a knob. Volkswagen models are typical representatives of this type of fog light switch.
