What is the maximum speed you are allowed to drive a bus in non-regular traffic outside built-up areas (not an autobahn or clearway for motor vehicles only)?

In Germany, buses in non-regular traffic (like chartered or tourist buses) outside built-up areas are generally allowed to drive at a maximum speed of 80 km/h. This speed limit is set for safety reasons because buses are large vehicles that require more distance to stop and are less maneuverable than smaller vehicles. It applies on regular roads outside towns, not on the autobahn or special motor vehicle roads, where different speed limits may apply. Knowing this rule helps ensure the safety of passengers and other road users.
