> You can't legally enter an intersection (advance past the stopping line if present) until you are clear to perform your transit of the intersection.

Yeah, I've seen tickets written for this in Emeryville, CA for cars that entered on green and weren't going to clear the intersection in the next ten minutes. (I don't know if the intersection is still that bad.) Bicycle cop, because there was no way they'd get a car in there.

> Left on red is never legal

I recall that this was legal in Michigan, where I grew up, but it either had to be onto or off of a one way street. I could never remember which, so I didn't try it.

But I did see someone make a left on red on market street in SF from the rightmost lane, which is very illegal.
