Snowmobiling While Intoxicated (SWI)
It is illegal to operate a snowmobile while under the influence of alcohol or drugs when you are on any property that is open to the public.
- Wisconsin’s prohibited limit of intoxication is 0.08% blood alcohol concentration. This limit is strictly enforced.
- By operating a snowmobile in an area open to the public, you must provide a breath, blood, or urine sample if requested by a law enforcement officer. If you refuse, you will be charged with an additional violation.
