Which feature helps control vehicle access to a facility?

• A. Public parking lot signage only
• B. Badges for pedestrians only
• C. Vehicle access control systems
• D. Interior design color

Answer: (C)

Controlling entry for vehicles requires a mechanism that verifies and permits only authorized vehicles to pass a boundary. Vehicle access control systems do exactly this by pairing entry barriers or gates with credentials—such as RFID tags, issued decals, or license plate recognition—and connecting to authentication and logging functions. This setup ensures that a vehicle cannot enter without being recognized or explicitly granted access, and it can trigger alarms or alerts if an unauthorized vehicle approaches. Signage at a public parking lot can guide drivers but it does not enforce access or verify identities. Badges for pedestrians address person-based access, not vehicles. Interior design color has no role in controlling who reaches the facility. Thus, vehicle access control systems are the feature that effectively manages vehicle entry.
