Question juridique clé
Whether X.'s conduct constituted a serious traffic violation under Art. 90 No. 2 SVG/LCR
Solution extraite
The excess speed of 21 km/h outside built-up areas did not, by itself, amount to a serious violation; the facts did not show a grossly inappropriate speed under the road or traffic conditions.
Motifs extraits
The canton relied on speed and loss of control, but the proven facts did not establish adverse weather, poor road conditions, limited visibility, or other circumstances making the conduct objectively grave. The maneuver was only linked to an excess speed insufficient for the threshold of a grave case.
