Wisconsin's Boating While Intoxicated (BWI) Laws and Penalties

Wisconsin law prohibits operating a motorboat while intoxicated by drugs or alcohol. A person can be convicted of boating while intoxicated (BWI) for operating a motorboat while:

• impaired by drugs, alcohol, or a combination of the two to "a degree which renders him or her incapable of safe motorboat operation"
• having a blood alcohol concentration (BAC) of .08% or greater (.04% for commercial boaters), or
• having a "detectable amount" of a controlled substance in the blood.

In other words, a BWI can be based on the amount of drugs or alcohol in the boater's system or actual impairment from drugs or alcohol.

BWI Penalties

The consequences of a Wisconsin BWI depend on the facts of the case. But generally, BWI penalties are:

• First offense. A first-offense BWI generally carries $150 to $300 in fines.
• Second offense. Where a BWI offender has had one prior BWI conviction within the past five years, the second BWI carries five days to six months in jail and $300 to $1,000 in fines.
• Third offense. Where a BWI offender has had two prior BWI convictions within the past five years, the third BWI carries 30 days to one year in jail and $600 to $2,000 in fines.
• BWI involving injury. If a BWI offender "causes injury" to another person while boating under the influence, the offense carries 30 days to one year in jail and $300 to $2,000 in fines.

Judges must order all BWI offenders to be assessed for and comply with recommended substance abuse treatment. And anyone convicted of a BWI must complete a state-approved boating safety program.
