The alley dock skill simulates backing an apparatus from a street into a restricted space at what angle?

• A. 45 degrees
• B. 90 degrees
• C. 120 degrees
• D. 180 degrees

Answer: (B)

Backing into a restricted space like an alley dock is best simulated with a perpendicular approach to the street. The right-angle entry gives you the clearest line of sight to the dock opening and curb, while the rear of the apparatus can swing into the space with a manageable arc. This orientation minimizes the amount of rear swing needed and helps you control the truck as you slide into the confined area. If you approached at a shallower angle, the back-in path would require a longer swing and reduce visibility, making it harder to judge clearance. If you came in at a steeper angle, the rear would swing more aggressively and increase the risk of striking the curb or obstacles. Backing straight in along the street (a 180-degree line) wouldn’t simulate entering a tight side space from the street at all.
