Vehicle Operator SOP 023: Reliefs


This procedure provides information for bus operators to use the MDT of the CAD/AVL system during service when a relief operator is assigned. This procedure assumes the schedule has been pushed to the on-board CAD/AVL system. The process covers monitoring relief operator status, existing operator log off, and relief operator log on.
