Questione giuridica chiave
Whether the incident of 4 December 2017 constituted a serious traffic violation justifying license withdrawal
Decisione estratta
Yes. Driving while overtired and losing control of the car created a serious abstract danger and amounted to gross negligence; the incident was correctly classified as a serious violation.
Motivazione estratta
An overtired driver is fahrunfähig under traffic law. A serious violation does not require concrete injury to third parties; the near possibility of harm suffices. The driver ignored early fatigue symptoms and continued driving until he nodded off.
