Which barrier type is designed to stop active vehicle threats at access control points?

• A. Temporary Barriers
• B. Fencing
• C. Vehicle Barriers
• D. Concentric Circle

Answer: (C)

Active vehicle threats require barriers that can stop a vehicle in motion at the point where access is controlled. Vehicle barriers are built and tested to withstand and halt car or truck impacts, usually rated for crashworthiness, so they can block a vehicle from breaching the control point. They come in forms like crash-rated gates, rising bollards, and wedge barriers, all specifically designed to stop or redirect a vehicle before it can cause harm or intrusion. Other options don’t provide that level of crash resistance at an access point: fencing mainly serves as a perimeter barrier but isn’t guaranteed to stop a determined vehicle; temporary barriers are not designed for sustained high-threat protection; concentric circle is a planning concept for layered defense, not a single barrier type.
