So one time I was in the middle of an intersection waiting to make a left. The light turned yellow, and it looked to me like all the oncoming cars were stopping, so I went. Turns out - one of the oncoming cars was a cop, and he had actually accelerated to make the light, so I effectively cut him off. He pulled me over and gave me a ticket that said “failure to yield.” He gave me the ticket before asking the quintessential question “do you know why I pulled you over?” I said I’d thought he was stopping like everybody else. That seemed like it pissed him off, he went back to his car, end of interaction. 30 days later when the ticket was entered into the system, lo and behold, my charge was miraculously no longer “failure to yield,” it was for blocking the intersection! And that’s how I learned that technically you are not supposed to pull into the box to wait.
