I heard a similar story from a driver who was traveling with two other drivers in the boonies, I think in Arkansas or Louisiana. A sedan followed them, and he called this guy on the CB and ordered him to pull over. The sedan didn't have any flashing lights or markings, and the driver debated whether or not to pull over, but he eventually did. The driver of the sedan had a uniform on and a very officious manner. He issued him some kind of citation, I don't remember what for. There was some debate on the roadside over the authenticity of the citation and of the officer himself. The driver did some checking later. The situation was a bit murky but he ended up paying the fine. He was never quite sure of the officer's actual title or jurisdiction, but iirc the fine was small and he thought it better to pay than have his license suspended or have a spot on the map he could never go again.
