This is a bad assumption to have. Just because a gate is closed, it 
doesn't mean your not allowed access.

barrier=gate means it's a gate & nothing else. It could be open/closed & 
all sorts of traffic could legitimately have access.

Tag what you see on the ground. If you don't know, don't tag it.
