Which statement correctly describes a characteristic of cantilever/barrier gates?

• A. They pivot on posts
• B. They move along a track
• C. They are supported without contact with the ground
• D. They require underground power feeds

Answer: (C)

Cantilever/barrier gates are designed so the barrier arm is supported without touching the ground. The arm is cantilevered from a post or column and guided by rollers, staying off the surface as it extends or retracts. This arrangement allows a wide, unobstructed opening and reduces wear on the pavement, since there’s no track or ground contact for the arm. While some gates may pivot on posts, sit on tracks, or use underground power feeds, these features are not what define cantilever barriers. The key characteristic is the arm’s support without ground contact.
