Why is it dangerous to leave rear fog lights on when they're not needed?

They can be confused with brake lights
Correct answer

DVSA explanation

If you don't switch off rear fog lights when the fog has lifted, drivers behind may find it difficult to see your brake lights. This can be a particular problem on wet roads and on motorways. If you leave your rear fog lights on at night, drivers behind are likely to be dazzled and this could put you both at risk.
