In foggy weather, how should we use lights when driving?
Should fog lights be turned on on foggy days or double flash?
Regarding whether double-flashing or fog lights should be turned on in foggy days, the most controversial issue is that many people think that double-flashing will be more conspicuous than fog lights. Is this the case?
Actually it is not. The double flash just looks "conspicuous", but the actual effect cannot be compared with the fog light at all.
Double flashing lights have not been specially designed like fog lights. The light emitted is irregular scattering like tail lights, not regular radial. Secondly, the brightness of double flashing lights is far less than that of fog lights.
At the same distance, black cars with fog lights are obviously more prominent than white cars with double flash lights. Therefore, the light source and brightness of fog lamps are more suitable for low visibility weather than double flashing.
It 's better to open double flashes than not open?
The full name of the double flash is "danger alarm flash", as the name implies, it is a signal light used to signal other vehicles to slow down or stop in an emergency. If it is turned on during normal driving, the following vehicle will not be able to judge the intent of the preceding vehicle, and it is not known whether the preceding vehicle is stationary or driving. When the vehicle is really in danger and needs to stop the vehicle in time, the rear vehicle may have an accident before stopping.
What is the situation where double flashing is allowed in traffic regulations?
We often say that it is exercised according to regulations. This is undoubted. But the reality is that sometimes our understanding of traffic regulations is also biased. The domestic traffic regulations stipulate that the premise of double flashes in rainy and foggy days is "highway".
It is normal to turn on as many light warnings as possible due to poor visibility on the expressway. But many riders "appropriate" this traffic regulation to urban roads, which is not appropriate.
