In such a heavy rainstorm, all the cars on the road are flashing. Is it safer or less safe?
When encountering rainy days, how to use lights correctly, today I will talk about it according to the situation.
In most cases, there is no need to turn on double flash
First of all, on ordinary rainy days, it does not need to use double flash.
The more formal scientific name of double flash is called "danger alarm flasher".
This light is mainly used to alert other cars when encountering malfunctions, accidents, or dangers. In fact, it functions a bit like a warning triangle.
If it's not raining heavily, just a little bit, and you're on the other side of the road, it's hard to tell whether the car in front is driving normally or if it's malfunctioning and has stopped there.
If there is a broken down car or a car in an accident, parked in the middle with double flashers on, it will make people think that he is driving normally with double flashers on a rainy day, and he will hit him with a "bang", and he will not be able to brake. Stayed.
According to the paper test data, the stopping distance from 100km/h on rainy days is 119.4 meters. For comparison, the stopping distance of most current family cars from 100km/h is about 40 meters on dry ground. The braking distance in rainy days more than doubled.
Moreover, using double flashes indiscriminately may increase the probability of secondary accidents.
Since the double flasher and the turn signal have the same light source, once the double flasher is turned on, some cars are not designed to give priority to the turn signal.
When you change lanes, both lights are flashing. Who knows whether you are turning to the left or to the right? It is very likely that you will misjudge and cause a traffic accident.
Interested friends can try it on their own car. When the double flashers are turned on first, you can then turn on the turn signal. Will it give priority to the turn signal? You are welcome to share and discuss it with everyone in the comment area.
In these situations, double flashing is required
When encountering a relatively heavy rainstorm, it depends on the situation. The traffic regulations do recommend turning on the double flashers.
Article 81 of the "Implementation Regulations of the Road Traffic Safety Law of the People's Republic of China" stipulates:
When a motor vehicle is driving on a highway and encounters weather conditions with low visibility such as fog, rain, snow, sand, dust, hail, etc., and the visibility is less than 100 meters, it is necessary to turn on the fog lights, low beam lights, position lights, For front and rear position lights and hazard warning flashers, the vehicle speed must not exceed 40km/h, and a distance of more than 50 meters from the vehicle ahead in the same lane must be maintained.
Think about it, one car is only 4 or 5 meters, the distance of 10 cars.
If the visibility is less than 50 meters, the vehicle speed cannot exceed 20km/h, and the vehicle must exit the highway as soon as possible.
To put it bluntly, it is only recommended to turn on the double flash in particularly heavy rain, snow and fog weather.
For example, our friends encountered this rainy day two days ago. The visibility was only about 50 meters. Without double flashing, it was basically impossible to see the car in front, and the speed could not be too fast.
Turn on double flash, no problem, continue 120, it won't work.
It is more recommended to turn on the fog lights
In fact, on rainy days, regardless of heavy rain or light rain, the fog lights can still be turned on.
Or the provisions in Article 81 of the "Regulations on the Implementation of the Traffic Safety Law of the People's Republic of China":
When encountering rainy days on this highway, as long as the visibility is less than 200 meters, you need to turn on the fog lights.
And the double flashes just mentioned when the high-speed visibility is less than 100 meters must also be used with fog lights.
It can also be seen that fog lights are actually more eye-catching, more reasonable and safer than double flashing.
There is also test data. Under the same rainy conditions test, when the double flashers are turned on, the longest distance for the vehicle in front to be recognized by the vehicle behind is about 138-183 meters; and when the fog lights are turned on, the distance to be recognized is more than 147-200 meters. .
This 200 meters is limited by the detection equipment. In human terms, even if it is 200 meters further away, it is actually possible to see it.
The sooner you see it, the sooner you can respond, which is safer for everyone.
What should I do if the front fender cannot be scraped clean?
So using lights correctly is to allow others to see us better and see us.
We ourselves also need to be better able to see others clearly. Some friends’ car windshields are completely mushy and cannot be wiped clean no matter how hard they are wiped. It is also very dangerous in heavy rain. What's the use of flashing lights and fog lights over there.
Then why can't the front fender be wiped clean? Is it a wiper problem or a front windshield problem? Or is there something wrong with me?
What should I do if I want to check it myself? How to solve problems?
These are all done for you, it’s not as difficult as you think.
