A bus has a mirror (19) attached to a support arm (11) by a joint (23), positioned above the safety zone (18) extending up from the ground. A swivel axis (24) extends horizontally and transverse to the direction of travel (10). The mirror can swivel from the operating position, in which is located at least partially in the safety zone, into a deflected position in which it is completely out of the safety zone. |
