Which best describes the role of blind spots during alley docking?

• A. They play no significant role.
• B. Obstructions obscured by blind spots should be warned to the driver/operator.
• C. They are eliminated by mirrors alone.
• D. They only matter during daylight.

Answer: (B)

Blind spots are areas around the apparatus that the driver cannot see directly from the cab, especially during tight alley docking where the vehicle is close to walls, curbs, or other equipment. Because obstructions can be hidden from the driver's view, the safest approach is to have a spotter or crew member who can observe those hidden areas and warn the driver as soon as an obstacle enters the path. This communication lets the driver adjust position or stop in time, preventing contact or injury. Mirrors and other visibility aids help but do not eliminate blind spots on their own, and these hazards exist regardless of lighting, so constant, clear guidance from the spotter is essential for safe docking.
