The most recognizable form, these feature three rotating arms.

At its core, a turnstile is a form of gate which allows one person to pass at a time. It is designed to enforce a "one person, one credential" rule, ensuring that only authorized individuals can enter a specific area and that "tailgating" (an unauthorized person following an authorized person closely behind) is prevented.

By the early 1900s, New York City’s subway system adopted them. The iconic waist-high, three-arm "tripod" turnstile became a global symbol of urban transit. Its design is deceptively brilliant: the arms are spaced so that even if someone tries to squeeze through, the next arm swings just in time to block them—unless they break the law (or the mechanism).
