Many people who don't have to turn on the double flash are on paper! Visibility is low in foggy days, and the strong penetration of fog lights can really make us notice the vehicles in front, but pay attention! However, in foggy days, it is difficult for us to judge the speed, distance and even width of the vehicle ahead by fog lights. Often, we only see two yellow lights, and two seconds later, we find that it is actually a turtle-speed truck or even an electric tricycle. When we can see the situation of the vehicle in front, the distance may be less than ten meters!
At this time, the function of double flashing comes, because you don't know the distance of the car in front, and you don't know whether the car in front is driving or stopping. What will you do at this time? Of course it's slow! When the speed drops, the probability of accidents is naturally low; Also, it is sometimes difficult to judge whether the car in front is in the same direction or in the opposite direction in foggy days, especially if the lane is too narrow or curved, and there are many vehicles overtaking and speeding in foggy days. At this time, the warning function of double flashing is more important.
Although the country has regulations on low-speed driving in foggy days, the fact is that even if the visibility is less than 10 meter, there are many people driving at a speed of more than 60, let alone overtaking in foggy days. I estimate that 90% drivers have done it, so just turn on all the lights that can be turned on in foggy days, especially the double flashing! I would rather let you brake suddenly because of my double flashing, and I will also let you slow down within a safe distance from me!
I think China traffic law and driving school examination should focus on the training and legislation of automobile lighting. First of all, automobile lighting can be divided into distance light, danger warning flashlight, fog light, width light, turn signal and so on. Every lamp has its function and division of labor. I often watch the opposite car with high beam and fog lights on at night when the moon is bright and windy. Maybe he doesn't know where the fog lights are on and the light switch is always on, and the dashboard doesn't look at it at all. I can't adjust the low beam. Maybe he didn't even know when he scolded others for turning on the lights and shaking their eyes.
