Kernrechtsfrage
Whether the lane change during overtaking constituted simple or gross violation of traffic rules under Art. 90 SVG.
Extrahierter Entscheid
The conduct amounted to a gross violation because he ignored important traffic rules in a seriously dangerous way and acted with at least unconscious gross negligence.
Extrahierte Begründung
He changed lanes abruptly without properly checking the overtaking lane. The police vehicle was clearly perceivable, and he should have deferred the maneuver. The omission reflected a serious lack of care and disregard for others' safety.
