Of course, I always stop when I see a cop, that's elementary; I will stop for a red, and if traffic is nonexistent (nothing going to trip a signal), I will roll it from that stop. Stop signs, I usually treat as a yield, just like most drivers do. Also, if I'm in a dedicated turn lane, my bike alone won't flip the switch, so I'll roll it when the straight lanes go green, and just yield to oncoming.

Tickets? You have to just about ASSAULT someone with a fender to get a ticket, or be speeding 20+ over in town; the PD around here holds pretty tight to the "no blood no foul" philosophy. I think I've seen 2 cars pulled over this whole year so far.
