What is an Active Vehicle Barrier (AVB)?

• A. Physically impedes threat vehicles; most effective measure to stop gate runner.
• B. A digital security system
• C. A decorative fence
• D. An audible alarm

Answer: (A)

An Active Vehicle Barrier is a device designed to physically stop a vehicle at a secured entry. It operates as an active defense: sensors detect a vehicle and the barrier engages automatically, creating a hard, crash-rated obstruction that halts the vehicle in its tracks. This immediate, tangible stopping power is what makes it the most effective way to counter a gate runner, since it prevents the vehicle from breaching the gate rather than just signaling or delaying it. Digital security systems manage access logic, surveillance, and alerts but don’t by themselves stop a vehicle. A decorative fence offers little resistance to a fast, heavy vehicle, and an audible alarm only warns; it doesn’t physically prevent entry.
