161. 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.

When may front fog lights be used in Belgium?

Front fog lights may only be used during fog, snowfall or heavy rain. They may not be used simply because it is dark or because the driver wants additional illumination.

Can front fog lights replace dipped beam in Belgium?

Yes. When their use is permitted because of fog, snowfall or heavy rain, front fog lights may replace dipped beam or high beam, or they may be used together with those lights.

Is there a minimum visibility distance for using front fog lights in Belgium?

No specific visibility-distance threshold applies to front fog lights under the current rule. Their use depends on the presence of fog, snowfall or heavy rain. The 100-metre visibility threshold applies to rear fog lights in fog or snow, not to front fog lights.
