A company wants to protect the front entrance of its office building after a rash of vehicle-ramming incidents in the area. Which physical security measure would BEST stop a car or truck before it can reach the doorway and injure employees or damage the facility?
Bollards are short, sturdy vertical posts-often steel or concrete-that are anchored into the ground to resist vehicle impact. Crash-rated bollards are specifically designed to prevent ramming attacks by stopping or severely slowing vehicles before they reach a protected area. Cameras, lighting, and badge readers improve observation or access control but do not physically stop a moving vehicle. Fences may slow a vehicle but are typically installed around perimeters rather than directly in front of building entrances and are more easily breached than crash-rated bollards.
