What should I do when driving a motor vehicle in foggy or foggy weather with low visibility?

In this case, fog lights are usually turned on when driving at high speed, so you should drive slowly into the nearest service area and wait for the fog to disperse. You can't stop on the highway, you can only walk slowly until you are safe. If you stop driving, it will easily lead to a serial collision. In short, turn on the fog lights, turn on the double flash, and slow down to about 20 miles until the fog clears.
