What Minnesota Law Says About BUI

Minnesota Statute 169A.20 makes it illegal to operate or be in physical control of a motorboat on any waters or boundary waters of the state while impaired. “Motorboat” is defined broadly: any watercraft propelled by machinery, including boats with detachable trolling motors. If the engine can move the vessel, the statute applies.

Physical control is the element that catches many people off guard. You can be charged with BUI for sitting at the controls of a boat even if the engine is off, as long as the boat isn’t anchored, beached, or secured to a dock. The charge is sometimes called BUI and sometimes BWI; both refer to the same offense under Minnesota law.

The legal limit is a blood alcohol concentration (BAC) of .08 or higher, measured at the time of operation or within two hours of it. Impairment by controlled substances, including marijuana, methamphetamine, cocaine, and certain prescription medications, can also support a BUI charge independent of any BAC reading.

BUI Penalties Under Minnesota’s Four-Degree Framework

Minnesota structures BUI as an enhanceable offense, meaning prior convictions increase the severity of the charge. The four-degree framework mirrors the DWI structure exactly, and prior DWI convictions count toward BUI enhancement and vice versa.

• Fourth-Degree BUI (first offense, no aggravating factors): misdemeanor; up to 90 days in jail and a fine of up to $1,000.
• Third-Degree BUI (one aggravating factor, or refusal to submit to chemical testing): gross misdemeanor; up to 1 year in jail and a fine of up to $3,000.
• Second-Degree BUI (two or more aggravating factors, or refusal plus one aggravating factor): gross misdemeanor; up to 1 year in jail and a fine of up to $3,000.
• First-Degree BUI (three or more prior DWI or BWI convictions within the past 10 years, or a prior felony DWI or BWI): felony; up to 7 years in prison and a fine of up to $14,000.

Administrative consequences extend well beyond criminal penalties. A BUI conviction can trigger boating privilege suspension for a minimum of 90 days during boating season, driver’s license revocation depending on your prior record, and revocation of ATV and snowmobile operating privileges. Boat forfeiture is a separate civil proceeding: upon a qualifying BUI arrest, law enforcement can seize the vessel, and the owner has 60 days to file a challenge or risk permanent loss of the boat.

Aggravating Factors That Raise the Stakes

Under Minnesota law, three circumstances qualify as aggravating factors: a prior DWI or BWI conviction within the past 10 years, a BAC of .16 or higher, and having a child under age 16 on board at the time of the offense. A single aggravating factor is enough to elevate a first-time BUI from a misdemeanor to a gross misdemeanor. Refusing chemical testing doesn’t count as an aggravating factor in the same way, but it operates as an independent circumstance that can increase the degree of the charge on its own.

One detail specific to boating: open containers of alcohol are legal on a Minnesota boat, unlike in a motor vehicle. Visible alcohol consumption can still prompt a BUI investigation, and the open container rule won’t protect against a charge once an officer determines impairment. DNR officers and local law enforcement maintain heightened enforcement presence on Memorial Day, Fourth of July, and Labor Day weekends. Probable cause standards for stopping a boat also differ from vehicle stops; an officer may approach for a perceived safety concern without the same level of articulable suspicion required on a highway.

Defense Strategies in BUI Cases

We examine every BUI case from the initial water stop through the chemical testing procedure. On-water enforcement creates procedural and evidentiary challenges that don’t arise in standard DWI cases, and those challenges are worth scrutinizing carefully.

Field Sobriety Tests on the Water

Field sobriety tests administered on a boat are inherently unreliable. The instability of a vessel makes the walk-and-turn and one-legged stand impractical, and those results can be challenged. Alternative tests sometimes used on the water, including the horizontal gaze nystagmus test, finger-to-nose test, and reverse alphabet test, are each subject to their own legal scrutiny. The two-hour window for chemical testing applies to BUI as it does to DWI, but logistical delays on the water can make compliance harder for the state to establish.

Other Issues We Scrutinize in Every Case

Beyond field testing, several additional issues can affect the strength of the state’s case:

• Lawfulness of the initial stop: Whether the officer had sufficient basis to approach and investigate can be a contested issue.
• Physical control: When multiple passengers were present, whether any particular person was actually in control of the boat is a factual question and a potential defense.
• Breath-testing equipment: Minnesota uses the DataMaster DMT for evidentiary breath testing; calibration and proper operation are requirements that can be challenged.
• Substance-based impairment claims: When the state alleges impairment by a controlled substance rather than alcohol, it must prove actual impairment, not merely the presence of a substance.

Our decades of familiarity with Ramsey County District Court, where St. Paul BUI cases are heard, informs how we read the strength of the state’s case and how we approach prosecutors. That local knowledge shapes our strategy in every case we take on.
