Am I reading this wrong or did you attempt a right turn without stopping at a red light? If so, I'd say that not stopping rather than hesitating was your mistake.

I don't mean to be judgmental here, but that would be my suggestion for future safety. Yellow lights freak me out because I know there are drivers who will come flying up to make a right turn before it turns red. Consequently, I generally stop at yellow lights too.


Edit: I just re-read it. It sounds like I misunderstood before and that you hesitated before braking rather than hesitating before turning. In that case, this sounds like a standard right hook where the driver simply failed to yield. I would assign 100% of the blame to the driver in that case, even while acknowledging that we as cyclists need to watch out for ourselves and do what we can to avoid these things.
