What lights must be turned on when driving in foggy weather?

[ValerieLee]

When driving in foggy weather, the following lights need to be turned on: 1. In heavy fog, you should turn on your position lights and headlights. If your vehicle is equipped with fog lights, both front and rear fog lights should be activated, as fog lights have strong penetration and can help other vehicles identify your car more easily. 2. In addition to turning on the fog lights, you should also activate the hazard warning lights (double flashing lights), as the flashing can serve as a warning. Just remember to switch them off when making turns. Below are some precautions regarding the use of fog lights: Fog lights are brighter than regular vehicle lights and have strong scattering effects, so they should not be turned on when not needed. Otherwise, they may interfere with the vision of other drivers, especially those of oncoming vehicles, and in severe cases, could lead to accidents.
