Yes, we can help you find evidence of this "obedience to obey" charge (it does exist) and what exactly it means to be cited for it.
The reason you were unable to find section 3111 (9) in the Pennsylvania Vehicle Code is that it does not exist, however the 9 we bet is really the letter A written unclearly by the law enforcement officer. Section 3111 (a) not only exists, but is exactly what your citation for "obedience to obey" would fall under.
Pennsylvania Vehicle Code 3111 is titled obedience to traffic control devices and in subsection (a) it basically says that unless otherwise directed by a uniformed police officer, "the driver of any vehicle shall obey the instructions of any applicable official traffic-control device." Traffic control devices in Pennsylvania can mean a speed limit sign, stop sign, yield sign, etc.
We have heard from others that have been cited under this part of Pennsylvania law and it appears to be a "catch all" for cops when they want to give you a break. By giving you a ticket under 3111 (a) they still cite you for a violating a traffic law, but without you getting points assessed.
So say the offense you were caught for was speeding 10 mph over the limit, if you were given a speeding ticket for it, you would get 2 points on your driving record. Instead if you were cited under 3111 (a) for the speeding offense, you would receive zero points.
If you pay the fine for this ticket you will still be convicted of a moving violation that will go on your driving record, but without it being assigned as a specific offense (speeding ticket, running a red light, etc.) it may be enough for your car insurance company to not raise your car insurance rates.
