Key legal question
Whether the conduct constituted a severe traffic violation under Art. 16c SVG rather than a medium violation.
Extracted holding
The driver seriously endangered others by driving too fast for snowy conditions and losing control of the vehicle; the violation was severe.
Extracted reasoning
The speed remained far too high for the snow-covered road, creating an increased abstract danger for other motorists. The driver acted at least grossly negligently, given the obvious risk and his inadequate speed reduction and braking response.
