When are motorcyclists allowed to use high-intensity rear fog lights?

Explanation: If your motorcycle is fitted with high-intensity rear fog lights, you must only use them when visibility is seriously reduced. That's when you can see no further than 100 metres (328 feet). This rule about high-intensity rear fog lights applies to all motor vehicles.
