"Impeding movement of traffic prohibited. --Except when reduced speed is necessary for safe operation or in compliance with law, no person shall drive a motor vehicle at such a slow speed as to impede the normal and reasonable movement of traffic." -- https://codes.findlaw.com/pa/title-75-pacsa-vehicles/pa-csa-sect-75-3364.html -- Completely up to the attending officer's interpretation and discretion. Happens all the time. That also goes for going 50 on a 65mph two lane and backing up traffic behind you. Human nature as it is, those motorists will put themselves and others at risk by attempting to get around you in inappropriate places. That's reality. I don't know of a single one of these cases where the state lost.
50 MPH in a 70 MPH zone is NOT hardy: "Impeding movement of traffic". Some may get annoyed, but moving at 50 MPH is clearly MOVING and far from"lmpeding"!
