The road I was on was backed up to Timbuktu because of this:
We all sat and stared at the schmuck in the van who apparently thought the no left turn sign didn’t apply to him and ended up stranded in the intersection. I was amused watching the construction worker point out the no left turn sign (can’t see it in the picture, but it was huge. And flashy. ) Bet he was nicer than I would have been.
