IV.A. Some circumstances when you have no other choice include: a stalled vehicle in front of you, having to get out of a stall, turnarounds on your route.
IV.B. A rear engine transit has a blind spot of five car lengths. A front engine transit with a door in the rear still has a blind spot of 12-15 feet.
IV.C. Distribute Handout #2, Backing the Bus. Have participants follow along as you review it. Be sure to indicate where your procedures may differ, e.g., you may require that the lookout be outside the bus.
IV.C.5. This procedure is for unplanned turnarounds. If a turnaround is part of a route package and done regularly, you may choose to tell people that they don't have to follow this procedure. However, remind them to be alert to unusual or different things that may affect backing safety, e.g., a new mailbox or a moving van.
