Key legal question
Whether the municipality is entitled to appeal traffic measures on a cantonal road.
Extracted holding
No. Because the measures concern a cantonal road and are outside municipal autonomy, the municipality lacks standing to challenge them.
Extracted reasoning
Traffic measures on cantonal roads are ordered by the cantonal police department under delegated cantonal competence; the municipality has no autonomous competence or transferred task in this area, and mere input or suggestions to the canton do not create a right of appeal.
