Beware!! Green Motion will charge you a L68 admin fee for every traffic violation. Processing probably takes them two minutes. But maybe this is what they are doing instead of waiting on customers. I had to wait a long time. In Bristol, following GPS and traffic will lead you into Bus Lane violations, with no way to escape except by turning around or driving on the wrong side of the street. I was not even aware I was in a Bus Lane until two months later when I got the L68 fee from Green Motion and the L35 fine from the unfriendly city of Bristol. So far, I have received two violations. I hope I do not get more.
