The following, an acquaintance of mine owns a 50s Simsonroller (type Schwalbe). As this one is allowed to drive ABE 60 KMH according to papers, I discuss with him for the following question. Since the MINDEST speed on German motorways is 60 KMH to be able to drive them at all, I think he may use them. His opinion: He may not!. In the case of expressways, we agree, but we both know not if it is true!!. Even police officers, who we interview Maybe we get here a( “Legally safe ” answer/information. Thanks in advance for your “toe” to answer me, and you all a nice Easter-WE. Edelschrauber01.
