Whew.... I just went through Parker in Johnson county not Dallas county. Population 15...
The only thing in there that would be challengeable in those would be all riders must carry I'D. There is nothing in state law requiring it. You would be required to provide name DOB, address whhen detained, just not required to carry I'D, although it is a good idea in case of incapacitating accident. stop sign rule fall under traffic regulation in general and bike specific regulation.
This is what happens when groups blow stop signs with no regard for cars who stop per state law the law applies to both. Cars and bikes.
