Driving with fog lights on in foggy weather works because the light from fog lights penetrates better, making it more likely that other drivers will notice your vehicle.

ANSWER · A

When driving in foggy weather, both front and rear fog lights should be turned on. In very heavy fog, hazard warning flashers should also be turned on. The main purpose of turning on the fog lights and hazard warning flashers is to allow other drivers to see you better and to avoid rear-end collisions and sideswipes.
