It's the Law

Alcohol and Drugs


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.

The following conditions determine if you are boating under the influence.

  • 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.
