We were in Austin at a T intersection today. Right turn and left turn lanes. We were in the right lane. This is a new signal that includes pedestrian lights and bicycle lane lights. All lights are red. Left lane has red light. Right lane has red arrow. There is no "no turn on red" sign. No traffic is coming. I tap the horn and the person in front of me points at the red arrow. I just got home from work and scanned through code 544 and didn't see anything about a red right arrow signal. Is my impatient ass wrong in thinking you may turn right on a red arrow if there is not a sign saying otherwise?
