I'm pretty sure Colorado law says a cyclist can proceed through a red light after stopping, if it is safe and clear to do so. I know Idaho, Tennessee, and Mississippi have laws specifically stating so. Likewise a Stop sign can be treated as a Yield sign if it is safe and clear to proceed.

Of course that doesn't help you if you're trying to go straight across or turn left onto a busy road, with no other cars on your side of the intersection.
