When traveling on multi lane roads in Germany with dense traffic it is illegal for vehicles the right to go faster than those left lane?

In Germany, vehicles in the right lane are generally not allowed to exceed the speed of vehicles in the left lane on multi-lane roads. This is because the left lane is designated as the "fast lane" in Germany, and drivers are expected to move to the left lane when driving at faster speeds. If a vehicle in the right lane is driving faster than a vehicle in the left lane, it is possible that the driver could be issued a fine or penalty for obstructing traffic.
