Which entry term describes an exterior entry point for vehicles or personnel where one door must close before the other opens?

• A. Sally Port
• B. Security Vestibule
• C. Gateway
• D. Port of Entry

Answer: (A)

The key idea is a controlled entry point that uses two interlocking doors so that one must close before the other can open, creating a secure checkpoint outside the main area. This setup is known as a sally port. It functions as a staging area for vehicles or personnel entering a secure facility, allowing observation, searches, and verification before access is granted inward. A security vestibule can involve two doors, but it’s typically an interior or between-space entry rather than an exterior vehicle entry point. Gateway is a general term for an entrance, and a port of entry is a broad border-crossing term, not the specific jail security feature described.
