Question juridique clé
Whether the order for a control drive under Art. 29 VZV was lawful.
Solution extraite
No. The observed parking incident did not amount to sufficiently serious driving errors creating genuine doubts about driving competence.
Motifs extraits
A control drive requires conspicuous driving behavior with serious faults. The first backing maneuver was not deemed troubling by the police, and the subsequent forward parking was completed without incident. Positive medical fitness did not preclude review, but it also did not justify a control drive absent grave driving errors.
