From a legal standpoint, no it's not ok to ever run a red light, you have the same rules as cars have, obey those rules or get a ticket just like a car would. Not to mention from a safety standpoint, cyclists have run red lights thinking they had the clear then got hit by a car they somehow missed and was discharged from earth.

You can turn right on a red as long as you stop first, this is true with cars too.

Regardless if someone thinks it should be legal it's not and until it is you must obey the law or face certain penalties if you're caught. Depending on the city the cops may not care what you do, in Indiana the cops don't care, they figure if you get hit and permanently injured or killed that's on you.

But you do what you want, I obey the signs just like I do in a car...I do have a weakness for speeding in the car but if I get a ticket it's on me, of course I did once get a ticket for speeding on my bicycle! The only time I run a stop sign on my bike is out in the country where I have a long clear view of the road, but even then I will slow to about 10 mph and check over my shoulder for cops!
