What is the role of protective barriers in vehicle control?

• A. To physically prevent unauthorized vehicle access, channel traffic, and provide time for verification and response.
• B. To block pedestrian access only.
• C. To prevent air traffic.
• D. To block all entry permanently.

Answer: (A)

Protective barriers in vehicle control are meant to physically stop or slow vehicles approaching a restricted area, channel them along a safe path, and buy time for verification and response by security personnel. By using elements like bollards, crash-rated barriers, and gates, you create a controlled corridor that prevents unauthorized vehicle access while guiding legitimate traffic toward screening points. This reduces risk to people and critical assets and gives responders a moment to verify credentials and react to potential threats. The other options don’t fit because one focuses only on pedestrians, another targets air traffic, and permanently blocking all entry would ignore the need for controlled, authorized access.
