While you’re driving in fog, it becomes necessary to use front fog lights. What should you remember?

Only use them on dual carriageways

Switch them off when visibility improves

It’s illegal to use your fog lights in conditions other than when visibility is seriously reduced; that is, less than 100 metres (328 feet). Fog lights are very bright and, if you use them when visibility has improved, you could dazzle other drivers.
