Why is it dangerous to leave rear fog lights switched on after the fog has cleared?
It may seem like a small inconvenience. But, incorrect light usage can lead to a road traffic collision.
Fog logs may be confused with brake lights, this is why you must switch them off when the fog clears. The glare can make it difficult for other drivers to tell if you’re stopping or just forgot about the fog lights. This is especially true when it is dark, other drivers could be dazzled by the light which puts everyone in danger.
