229. Pluie
La pluie peut réduire la visibilité, l’adhérence des pneus et la maîtrise du véhicule tout en augmentant les distances d’arrêt. L’eau sur la chaussée peut également provoquer de l’aquaplaning, lorsque les pneus perdent le contact avec la route. Les conducteurs doivent réduire leur vitesse, augmenter la distance de sécurité, éviter les mouvements brusques de direction ou de freinage et utiliser les feux appropriés lorsque la visibilité est réduite. Une prudence particulière est nécessaire sous une forte pluie et lorsque l’eau s’accumule dans les traces de roues ou sur des routes mal drainées.
Do you have to reduce your speed in rain in Belgium?
Yes. Belgian traffic rules require drivers to adapt their speed to the weather conditions, visibility, road condition and traffic situation. Drivers must also maintain a sufficient safety distance and be able to stop before a foreseeable obstacle.
When must rear fog lights be used in heavy rain in Belgium?
Under the current Belgian traffic rules, rear fog lights must be used in heavy rain when the vehicle is equipped with them. They may not be used in other circumstances unless another permitted condition, such as sufficiently dense fog or snowfall, applies.
May front fog lights be used in heavy rain in Belgium?
Yes. Under the current rules, front fog lights may be used during heavy rain. They may replace the dipped or main-beam headlights or be used together with them.
Do you have to use normal vehicle lights when rain reduces visibility in Belgium?
Yes. The prescribed vehicle lights must be used whenever it is no longer possible to see clearly for approximately 200 metres, including when heavy rain reduces visibility.
What should you do if there is standing water on the road in Belgium?
Reduce your speed and avoid sudden steering or braking. Belgian rules require drivers to adapt their driving to the weather and road conditions, which includes water on the road and an increased risk of aquaplaning.
Will the fog-light rules for heavy rain change under Belgium’s new Road Code?
Yes. Under the new Code of the Public Road, rear and front fog lights are linked to heavy precipitation that reduces visibility to less than approximately 100 metres. This differs from the current rule, which specifically permits or requires fog-light use in heavy rain without that same visibility threshold.
