What is allowed on autobahns?

On German autobahns, stopping is only allowed on the hard shoulder in cases of emergency or breakdown. This rule is important for safety and traffic flow, as the hard shoulder is designated as a refuge area and not a regular lane. Driving beside another vehicle in the same lane is not allowed anywhere, including autobahns, because it can cause accidents. Leaving the autobahn on a farm track is generally not permitted, as exits must be official and marked to ensure safety and proper traffic regulation. Remember, the hard shoulder is exclusively for emergencies.
