These signs must be removed or covered once the vehicle/load is no longer considered oversize. Additionally, flags are mandatory at the widest points of any oversize load.

Furthermore, headlights and rear lamps of a permitted vehicle must be turned on during movement when accompanied by pilot car(s).
