I have two stop lights on my ride just outside of my office, one at the start of a busy overpass and one at the end. If I'm at the front, and the way is clear(On/off ramps from an interstate), I'll run the red just to not get stuck at the front of the huge pack of cars that builds up behind me.

There are 8 stop signs on my route, one that I always stop for. The others I slow way down and frequently stop as they're almost blind in one direction or another. I tend to slow down at all the stop signs, even when I don't have the stop in that direction. I've seen a lot of people blow through them(residential areas). I'd have gotten creamed if I hadn't slowed down on more than one occasion.
