You’re driving in fog that’s starting to clear. When should you switch off your high-intensity rear fog lights?

Explanation: Switch off your fog lights when fog starts to clear and visibility improves to more than 100 metres (328 feet). Don't leave your fog lights on when the fog has cleared, because they can cause unnecessary glare or distraction for other drivers.
