Here we have a T-intersection with the stop sign in the wrong place. This is a single road with a service road branching off on a sharp corner. However, the road is treated like it’s intersecting itself; If you’re heading westbound, you stop. If you’re heading eastbound, you don’t. If you’re a service vehicle leaving the gated and rarely used service road, you also stop. So eastbound traffic always has the right-of-way, creating a sort of shield for westbound traffic. The only time it’s necessary to stop is if a service vehicle is leaving the service road, heading west, and there are no eastbound cars coming. I’m no infrastructure expert, but I believe that kind of extremely specific circumstance calls for a yield sign more than anything.
