Can a municipality block off a street in order to have a snowmobile race?
Yes. A municipality may block off streets
under its jurisdiction to allow special snowmobile events, but may not
block off any state trunk highway or connecting highway or part thereof
for any snowmobile race or derby. The municipality must notify the local
police department and the county sheriff's office at least one week in
advance of the time and place of any snowmobile race or derby which may
result in any street or portion thereof of the county or municipality
being blocked off. Upon receiving such notice, the local police
department shall take such measures as it deems appropriate to protect
persons and property and to regulate traffic in the designated area and
its vicinity on the day of the race or derby. Wis. Stat. sec. 350.04(1).
