Key legal question
Whether the speeding constituted a grave traffic offense under Art. 90 no. 2 LCR
Extracted holding
The 30 km/h excess outside a locality was at the threshold; considering the concrete circumstances, the grave-offense qualification was not established.
Extracted reasoning
The court reaffirmed the fixed-speeding jurisprudence but held that the cantonal court could consider concrete factors where the threshold is borderline; no danger was caused and the measured speed had been assessed without safety deduction.
