Is it correct to double flash in foggy days?
When encountering bad weather at high speed, it is best to use fog lights. Because the fog lamp has strong penetrating power and the irradiation distance is150m, the driver's vision will not be limited, and he can observe the road ahead well. In case of downpour or storm, it is best to turn on the front and rear fog lights, so that the penetration of the lights will be stronger and driving will be safer.
Old drivers don't advise people to turn on double flashing lights. The penetration of double flashing lights is poor, which can only reach 100 meter. In bad weather, the double flashing lights have no effect. First, the driver can't see the road ahead clearly. Second, the rear car can't judge the next operation of the vehicle in front, which will increase the chance of traffic accidents.
When people are driving at high speed, they find that the visibility is very low. When it is less than 100 meters, they can turn on the double flash and fog lights at the same time, which is the safest driving mode.

Ten things to pay attention to when driving in foggy weather
1, rational use of lighting. Turn on the fog lights when driving in foggy weather. If the fog is heavy, you should turn on double flashing lights, but you can't turn on the high beam lights.
2. Pay attention to the speed limit. According to the different visibility, turn on the anti-glare low beam lamp, width indicator lamp and tail lamp, appropriately increase the driving distance and reduce the speed.
Don't slam on the brakes. Sudden braking can easily lead to rear-end collision, such as on the expressway, which is more likely to lead to a series of rear-end accidents. If you need to brake, you can lightly step on the continuous brake, which can not only control the speed, but also remind the following car.
4. honk the horn often. Frequent honking can be used as a warning to other vehicles. When you hear the horn of other vehicles, you should honk the horn immediately to remind you of your position.
5. Pay attention to the choice of driving route. If it is one-way three-lane, try to drive in the middle lane; If it is a one-way two-lane road, try to drive in the outer lane.
6. Try to avoid overtaking. The visibility is low in foggy days, which is not conducive to observing the situation of adjacent lanes and opposite cars. You should try to follow the car in front and avoid overtaking.
7, the front windshield defogging. If there is fog on the front windshield, you should turn on the air conditioner or slightly open the window to eliminate or avoid the fog on the glass.
8. Listen to all directions. When driving on the highway, once you hear the sound of a car colliding in front, you should stop at the side of the road quickly and turn on all the lights under the condition of ensuring safety. People in the car will jump over the guardrail and wait by the side of the road. At the same time, set warning signs along the outside of the road at a distance of 150 meters from the rear of the car, and leave the road quickly after completion.
9. Emergency treatment in case of traffic accident. When a traffic accident occurs, safety measures should be taken quickly to protect the scene and report the case in time; Personnel must stay away from vehicles and guardrails to ensure safety; Don't let the vehicles behind you crowd the emergency parking lane, so as not to cause inconvenience to traffic diversion, saving lives and clearing obstacles.
10, stay in the fog, and wait until the line of sight is completely restored before driving. In foggy days, drivers must wait patiently, and can't rush into foggy areas in order to seize time. Because when the fog has just dispersed, the fog along the expressway is often thick and light, so it is difficult to control the speed and it is more prone to traffic accidents.
