Why is it dangerous to leave rear fog lights switched on after the fog has cleared?

They may be confused with brake lights – If you leave your rear fog lights on when it’s not foggy, the glare they create makes it difficult for drivers behind you to tell if you’re stopping or have just forgotten to switch off your rear fog lights. This is especially problematic on wet roads and highways. If you keep your rear fog lights on at night, drivers behind you may be dazzled, putting them in danger.
