Horizontal sliding or swinging gates that exceed the ______ ft max leaf width limitation are permitted in fences surrounding a stadium.

The correct answer indicates that horizontal sliding or swinging gates in stadium fences can exceed a maximum leaf width limitation of 4 feet. This provision recognizes that certain structures, like stadium fences, may require larger gates to accommodate higher traffic and accessibility needs during events. The 4-foot limit suggests that for practical functionality and safety considerations, these wider gates can facilitate smoother ingress and egress for large crowds, especially in emergency situations where faster evacuations are necessary.

Other options would imply narrower restrictions which might not address the operational demands of a stadium environment. Thus, permitting gates wider than 4 feet allows for better management of large groups of people, ensuring that safety and operational efficiency are upheld while still adhering to building and safety codes.
