Would the municipality be liable if someone was injured during a snowmobile race or derby it sponsored or arranged?
No, unless the injury was caused by the
municipality's negligence. Wis. Stat. sec. 350.04(3)(a). A municipality
must post a notice to that effect in a conspicuous place, readily
accessible to all contestants and spectators, and must assist in
locating and identifying persons responsible for injuries that may
occur. Wis. Stat. sec. 350.04(3)(b).
