• Anyone who operates or attempts to operate a vessel is deemed to have given consent to an alcohol and/or drug test.
• Wisconsin law states that a person is considered to be operating a vessel under the influence of alcohol or drugs if he or she:
  • Has a blood or breath alcohol concentration of 0.08% or greater or…
  • Is under the influence of any controlled substance or any other drug, or any combination of alcohol, controlled substance, or drugs that renders that person incapable of operating safely.
