Under USMS 9.21(D)(4), what feature must vehicles used to transport prisoners have?

• A. A security screen (cage).
• B. No special feature required.
• C. Two separate locking compartments for guards.
• D. Rearview cameras only.

Answer: (A)

Safety in prisoner transport hinges on a solid barrier that keeps prisoners contained and separated from the driver. USMS policy 9.21(D)(4) requires vehicles used to transport prisoners to have a security screen, or cage, between the prisoner area and the occupant area. This physical barrier prevents prisoners from reaching into the cab, helps deter escape attempts, and protects officers during stops and disturbances while still allowing visibility and control of the interior. While features like rearview cameras can aid awareness, they do not provide the essential confinement that the security screen delivers.
