The majority of the Bureau's accidents occur when backing. The Superbus shall not be backed without the assistance of the Security Deputy when two Deputies are assigned to the Superbus crew. If only a Driver is available, he/she shall secure the assistance of other personnel.
The Security Deputy shall dismount the trailer unit and place him/ herself in a position of visual advantage. He/she will ensure the vehicle has proper clearance to back, and will direct the Driver in the proper manner. It is important therefore, that the Security Deputy always stands where the Driver can see him/her, since the mirrors move on a different axis, than the trailer. It is required that the Security Deputy constantly move his/her position to stay in the view of the cab mounted side mirrors, or in the direct view of the Driver.
Both the Driver and Security Deputy are responsible for compliance with this policy.
