What is the key characteristic of alley dock backing?

• A. Backing into a space alongside a dock
• B. Backing straight down an alley
• C. Backing while turning into a space that is 90 degrees to the truck
• D. None of the above

Answer: (C)

Alley dock backing centers on entering a dock space that is at a right angle to the truck’s approach. The trailer must be backed into a space that’s perpendicular to the truck, often requiring the driver to steer through a turning maneuver so the trailer swings into the dock opening from the side. This perpendicular entry is what defines alley docking and makes it distinct from backing straight into a dock or backing straight down an alley. So the key idea is: you’re backing into a space that is 90 degrees to the truck, not parallel to it or straight ahead.
