Michigan law prohibits anyone from boating while under the influence of alcohol or drugs. It is also unlawful for the owner of a motorboat to allow anyone else to operate their motorboat if that person is under the influence of alcohol or drugs.
If your blood alcohol content is 0.08% or greater by weight of alcohol as determined by a breath, blood, or urine test, you are considered to be under the influence of alcohol.
Michigan law establishes the following penalties.
- People arrested for boating under the influence are guilty of a misdemeanor. Upon a third conviction within 10 years, a person will be guilty of a felony.
- If a person boating under the influence causes great bodily injury or death of another person, he or she will be guilty of a felony.
By operating a motorboat on Michigan waters, you have consented to be tested for alcohol or drugs if arrested by a law enforcement official.
