In Germany the 60 km&#x2F;h is not required in terms of minimum speed. It is required in terms, that the vehicle is capable of driving that speed.<p>My Hanomag A-L 28 is a maximum speed in the papers of 78 km&#x2F;h. As such I am allowed on the Autobahn, even that I am driving only 50 km&#x2F;h or sometimes 40 km&#x2F;h on a hill. Because each hill does slow down a Hanomag considerably.
