Which security feature uses sturdy vertical posts to prevent vehicle intrusion along perimeters?

• A. Lighting
• B. Access control vestibule
• C. Bollards
• D. Industrial camouflage

Answer: (C)

This item tests how to physically block vehicles from crossing a facility’s boundary. Sturdy vertical posts called bollards are designed exactly for this purpose: they form a hard barrier that stops or redirects a vehicle, protecting people and critical assets at the perimeter. They can be fixed for continuous protection or crash-rated to withstand higher-velocity impacts, and some systems use retractable bollards to allow authorized vehicle access when needed. Lighting helps visibility but does not prevent a vehicle from entering. An access control vestibule manages pedestrian entry, not vehicle intrusion. Industrial camouflage focuses on concealment rather than creating a physical barrier against vehicles.
