230. 霧
霧は視界を大幅に低下させ、速度、距離、他の道路利用者の位置を判断しにくくします。運転者は減速し、車間距離を増やし、他者を眩惑しない適切な灯火を使います。前車だけを目印にせず、視界が突然変化することにも備えます。非常に濃い霧では、安全な場所へ停止することが最善の場合があります。
Do you have to reduce your speed in fog in Belgium?
Yes. Belgian traffic rules require drivers to adapt their speed to visibility, weather, road conditions and traffic. The posted speed limit may therefore be too fast when visibility is reduced by fog.
When must rear fog lights be used in Belgium?
Under the current Belgian rules, rear fog lights must be used when fog reduces visibility to less than approximately 100 metres. They may not be used in other circumstances unless another permitted condition applies.
May front fog lights be used in fog in Belgium?
Yes. Under the current rules, front fog lights may be used in fog. They may replace the dipped or main-beam headlights or be used together with them.
Do normal vehicle lights also have to be used in fog in Belgium?
Yes. The prescribed vehicle lights must be used whenever visibility is sufficiently reduced. Fog lights are additional or alternative lighting under the conditions allowed by the traffic rules.
Will the fog-light rules change under Belgium’s new Road Code?
The basic rule remains similar. Under the new Code of the Public Road, rear fog lights must be used and front fog lights may be used when fog reduces visibility to less than approximately 100 metres. The new code uses the same approximate 100-metre threshold for heavy precipitation as well.
