Hello, every morning and every evening you can watch the same picture on the A3 between Oberhausen and Cologne. On the left lane the cars crawl each other into the exhaust – the middle lane is almost free – on the right some trucks and a few cars. Now it is common that the traffic flow collapses the full left lane and almost comes to a standstill, while 2 lanes further on the right loosely continues with 90-100 km/h. As far as I know, is allowed to pass right, w the speed is not higher than 80 km/h and the difference in speed of the two adjacent lanes is not greater than 20 km/h. What if there is an almost empty middle lane between the almost standing queue on the left and the moving vehicles on the right? Does this still count as “right overtaking”? Do the vehicles on the right have to brake almost to the stand or up to a speed X, in order not to be regarded as right overtaking? But I’ve never seen it before.
