According to UL325, what is the maximum speed for residential gates (Class I or II)?

• A. 1 ft per second
• B. 2 ft per second
• C. 0.5 ft per second
• D. 3 ft per second

Answer: (A)

UL325 sets safety limits on how fast power-operated gates can move, to reduce the risk of injury if someone or something is in the way. For residential gates, classified as Class I or II, the standard limits the operating speed to 1 ft per second. That pace—about 0.3 m/s—keeps the gate’s kinetic energy low enough that safety devices can detect an obstruction and stop the gate promptly, protecting people, pets, and vehicles. The 1 ft/s limit is part of broader requirements on stopping distance, force, and braking behavior, all aimed at safer operation in home environments. Faster speeds would increase injury risk and typically wouldn’t meet UL325 safety criteria for residential classes.
