Which statement best describes the purpose of the AVB in security?

• A. It physically impedes threat vehicles; most effective measure to stop gate runner
• B. It is a visual deterrent with no physical impact
• C. It is used only for decorative purposes
• D. It randomly triggers alarms

Answer: (A)

Anti-vehicle barriers are designed to physically stop vehicles that threaten a secured perimeter. The best choice describes the AVB as a device that impedes threat vehicles and is the most effective way to stop a gate runner because its primary role is to provide a substantial physical obstruction that prevents a vehicle from breaching the gate or protected area. Visual deterrents, decorative use, or random alarms do not deliver the same level of protection, since they either don’t stop a vehicle or are functions of other systems, not the barrier itself. In practice, AVBs sit as a critical element in a layered security approach, engineered to withstand crashes and reliably interrupt vehicle access at gateways.
