338. Front fog lights
Front fog lights are low-mounted vehicle lights designed to improve illumination of the road immediately ahead when visibility is reduced by fog, snow or heavy rain. Their beam is generally wide and directed low towards the road surface.
Front fog lights should only be used in the weather conditions permitted by local traffic rules. They are supplementary lights and should not be used unnecessarily in normal visibility.

What are front fog lights used for?
Front fog lights provide additional low-level illumination when fog, snow, heavy rain or similar conditions make it difficult to see the road ahead.
Where are front fog lights located?
They are normally mounted relatively low at the front of the vehicle so that their wide beam illuminates the road surface without projecting as much light directly into fog or precipitation.
Should front fog lights be used in normal weather?
No. Front fog lights should only be used when conditions and local traffic rules permit them. Unnecessary use can create glare or distraction for other road users.
