Hi, I pulled off a little bit today, wg. sign 272, turning ban. Discussions with police officers are always bad, especially since only 10 euros, but I can not quite understand it. Downtown Cologne, double-track left turner with traffic lights. The double lanes are led with a structural separation, so a kind of sidewalk in between, next to each other. The prohibition sign stands on a post at the traffic light of the right track. For the left Sur there is also a traffic light. The turning ban then only applies to the separately guided right lane? Unfortunately to the sign also found nothing further, since someone knows something about it?
