If I am not completely wrong, then the non-seasonal equipment of the car costs since 1.1.05 about 20 Euro penalty. So with summer tires on snow on the road and stay lying and others hinder will be expensive. Question-1: Does this also apply to trucks, especially if the 2nd wants to pass the 1st lying down and also hangs and if then the 3rd also the standing track passes. Thus happens last (or penultimate) winter in Bavaria with the consequence that the Red Cross hot tea and warm blankets distributed to the bibbing car drivers. Question-2: Can you sue the truck drivers for damages if you stand in traffic with your expensive, but useless winter tires?
