Hi X

I think more than illegal to turn right on a red light (unless a rt turn light is there to give permission) it's a matter of yielding.  

11th is horrific right now w/the construction going on.  The other day I was westbound about a .25 mile from Taco Bell  and a HUGE SUV must have gotten frustrated and pulled out of our waiting, stalled lane into the eastbound lane (luckily no cars, lol) and after 1-2 minutes driving on the wrong side of the street pulled into the driveway of the Taco Bell, cut thru the parking lot and out towards 18th.   

You're correct about not entering an intersection if you can't clear it before light changes.  However, many folks on 11th.........stay in the rt lane even though there are plenty signs saying closed ahead.  So these who want to cut in.....hang on the side.  Traffic was moving slow, I entered the intersection and a car merged in leaving me stuck in intersection.  Boy was THAT stressful.
