DépassementBelgique
1. Dépassement
Le dépassement consiste à passer devant un autre usager circulant dans la même direction. Il implique normalement de changer de position ou de voie, de dépasser l’usager plus lent puis de revenir à la position appropriée lorsque cela peut être fait en sécurité.
Avant de dépasser, un conducteur doit s’assurer que la visibilité et l’espace sont suffisants, vérifier les rétroviseurs et angles morts, signaler lorsque cela est requis et s’assurer qu’aucun autre usager n’est déjà en train de le dépasser. La manœuvre doit être achevée sans dépasser la limitation de vitesse ni mettre en danger les autres usagers.
On which side must you normally overtake in Belgium?
Overtaking normally takes place on the left. An important exception is when the driver ahead has indicated an intention to turn left or stop on the left side and has moved left to perform that movement; in that situation, overtaking may take place on the right.
What must you check before overtaking in Belgium?
You must make sure that the road is clear far enough ahead, that no driver behind has already started overtaking, that you can return to the right without obstructing others and that the overtaking manoeuvre can be completed in a very short time.
When is overtaking prohibited in Belgium?
Overtaking on the left is prohibited in several situations, including where there is insufficient visibility, at certain intersections and railway crossings, near the crest of a hill or in a bend when visibility is insufficient, and when a vehicle is stopping or approaching an uncontrolled pedestrian or cyclist crossing in circumstances covered by the Road Code.
