Do I have to turn on the double flashing lights and fog lights at the same time when driving in a rainstorm?

You can turn on fog lights, because fog lights have strong penetration, but don't turn on double flashes, because double flashes are turned on when the car breaks down, which is prone to accidents in rainy days.

It is extremely important to turn on the low beam or the front fog light when there is heavy rainfall or even heavy rain. It is particularly important to emphasize that the low beam should be turned on instead of the high beam, because if the high beam is turned on at this time, the visibility of the driver will be extremely low due to heavy rainfall, and the sight of the owner will be blurred at this time. It is better to turn on the fog lamp at this time, because the fog lamp itself has stronger penetration ability.

Speaking of heavy rain, the road conditions are basically unclear at this time. It is important to turn on the front and rear fog lights and low beam lights, because the brightness and penetration of the rear fog lights are excellent, and the lighting effect is also excellent. Only by turning on these lights can the vehicles in front and behind be prompted.

In the application of vehicle traffic lights, double flashing lights are mainly used to remind drivers to pay attention to safety, or double flashing lights indicate that the car is out of order, and vehicles that need to pass should pay attention to driving safety. The most important function of double flashing lights comes from this; Low beam lights or fog lights also have their own functional areas. Low beam lamps are mainly used for prompting and lighting, and fog lamps are more convenient to use in foggy days.

Although there is no express stipulation in the traffic law that the double flashing lights of dangerous signals cannot be used in rainstorm weather, according to the daily car use habits, it is necessary to turn on the double flashing lights less, because the low beam lights and fog lights of cars are basically enough in rainstorm weather, which will not cause "misunderstanding" of signal transmission to other vehicles. Suppose that when a car with double flashing lights changes lanes, it is difficult for the car behind or in front to judge the light signal, which may easily cause safety hazards.
