Matters needing attention in safe driving in foggy days

The visibility is low in foggy days, so driving on the road is prone to traffic accidents. Drivers should pay attention to four "no's" to remind you to drive safely: 1, turn on the fog light, not the high beam; 2. Control the speed not to overspeed; 3. Drive in the middle, don't lean on the side of the road, and avoid pressing the line; 4. Don't wipe while walking.
