Is it wrong to flash twice in foggy weather?

When encountering foggy days in daily driving, many drivers habitually turn on the double flash, thinking that it is safer. However, some people think that fog lights should be turned on in foggy days, instead of double flashing. In fact, in my opinion, the influence of not turning on fog lights before foggy days is not particularly great. The most important thing is to turn on rear fog lights and double flashes.

Why does the front fog light have little effect?

Because the danger of fog lies in affecting the sight distance, there is no light to increase the sight distance of the driver at this time. Some people say that fog lights have better penetration, but that's just running by yourself. How far can you see or how far can you see?

I'm afraid we can only solve the sight distance problem by high-tech means. For example, some cars have infrared cameras, which image through infrared light emitted by objects, so the influence of fog can be minimized.

The rear fog lamp can improve visibility and indicate its position.

The rear fog lamp has high brightness and strong penetration. Some drivers turn on fog lights on foggy nights, and the lights are dazzling from a distance. This is the most important function of the rear fog lamp: to show its position, so that the rear vehicles can find themselves as early as possible and keep a safe distance. Therefore, it is very necessary to turn on the fog lights in foggy days.

According to the requirements of national standards for automobile lighting configuration, domestic cars should be equipped with at least one rear fog lamp, while the front fog lamp is not mandatory.

Double flash

I have to say that the utilization rate of double flash should be the highest in the country. Temporary parking on the roadside, towing, rainy and foggy days, even some drivers will turn on the double flash to remind them to get behind, and some drivers will use the double flash to communicate with other drivers. It can be said that various functions have been invented, and I think these usages are really impeccable.

However, some people think that double flashing can only be used when the car breaks down and has to stop at the side of the road. The reason is simple: according to foreign regulations, only when the car breaks down on the side of the road can you drive a double flash. If you drive at will, other vehicles will mistakenly think that you are in a stopped state, which will cause danger. I don't agree with this view, so I looked through the user manual. As a result, Toyota's user manual really means this.

But I think the description in Toyota's user manual is too general, so I looked through Volkswagen's user manual and found a wealth of contents, especially that it pointed out that "the local regulations on the use of flashing alarm devices must be observed". In other words, people don't insist that double flashing can only be used for emergency parking.

So do you want to turn on a double flash in foggy days? I think it is necessary.

First of all, I checked the Road Traffic Safety Law, which clearly stated the use of double flashing. So friends who are afraid of being fined for driving a double flash can rest assured.

Then I want to talk about the benefits of double flashing in foggy days.

Because the fog reaches a certain level, the driver can find a way to ensure that he doesn't hit the guardrail, so it's Amitabha. At this time, the driver is surrounded by white, and it is easy for the driver to get lost. Because people can keep balance and identify the direction, the important reason is that there are enough reference objects in the field of vision. In the case of heavy fog, there are few references, and the brain can only use limited clues to help you establish a sense of orientation, and the accuracy of this sense of orientation will become worse and worse with the movement of vehicles. At this time, the brain will become particularly insensitive to relatively static things. At this time, even if you can see the light of the fog lamp in front in theory, you can't actually detect it at the first time.

The function of double flashing is fully manifested at this time: because it will flash, when the brain and your eyes try their best to search for any useful image in the vast white fog, the flashing light in front must be the sun in the dark, which will attract your attention at the first time.

Drivers who have experienced heavy fog should feel this way. Many times, it is not the fog lights that attract your attention, but the double flashing. Chances are, you can't help saying, "I'll go, so here's the way."

I often run at high speed and have experienced a lot of fog, which is completely invisible to the hood. Can't see the guardrail, can't see the marking, can't see the direction of the road. I have to rely on navigation to guide me to the exit of the expressway. When you encounter this fog on the highway, you will not stop walking, and that kind of fear is still terrible to think of. In that case, you can see flashing double flashing lights, and you can't feel that kind of security without experiencing it.

In addition, the double flash is also a light for drivers to communicate. I don't know if you have this feeling: in foggy weather or rainy and snowy weather, cars are driving slowly with double flashes, controlling speed and keeping formation. No one cut in line or honked the horn. At this time, the double flash is like a communication link between all cars. Everyone tacitly responded to the bad weather, but they gained a sense of security.

The function of anything is not static. There is an idiom in Chinese called "Make the best use of everything", which I think is vividly reflected in China people, and so is the double flash.
