When does a driving permit class D or D1 lapse?

A driving permit of class D or D1, which allows you to drive passenger buses, lapses if its period of validity is not renewed in time. In Germany, these classes are valid for five years and must be actively renewed by presenting a medical certificate and an eye test. Not driving a bus for one year or ending employment as a bus driver does not cause the permit to lapse, as the permit’s validity only depends on timely renewal, not on employment status or active driving. Always make sure to renew the permit before it expires to keep it valid.
