This article covers Colorado's boating under the influence (BUI) laws and the penalties you'll face for a BUI conviction.

Colorado's Boating Under the Influence (BUI) Law

Colorado law prohibits operating or being in actual physical control of a vessel while under the influence of drugs or alcohol.

Colorado's BUI Law Applies to Motorized and Non-Motorized Boats

For purposes of Colorado's BUI law, the term "vessel" includes "every description of watercraft used or capable of being used as a means of transportation of persons and property on the water, other than single-chambered air-inflated devices or seaplanes."

This broad definition covers almost all types of watercraft, regardless of whether powered by a motor.

The Standard of Impairment for Colorado's BUI Law

A person can be convicted of boating under the influence for operating a vessel while:

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

Colorado's Boating Under the Influence (BUI) Penalties

The consequences of a Colorado BUI generally depend on whether the offender has prior BUI convictions. First and repeat-offense BUIs are misdemeanors with the following penalties:

  • First offense. A first BUI carries five days to one year in jail, up to 96 hours of community service, and a maximum of two years of probation, and the court can impose $200 to $1,000 in fines. The court also must order the offender not to operate a vessel for three months.
  • Repeat offense. Where a BUI offender has at least one prior BUI that occurred within five years of the current violation, the repeat offense will carry 60 days to one year in jail, 60 to 120 hours of community service, up to two years of probation, and the court can impose $500 to $5,000 in fines. The court also must order the offender not to operate a vessel for one year.

Judges have the option of suspending all or part of a jail sentence if the offender completes a drug and alcohol education or treatment program and agrees to stay alcohol-free for one year. For a first offense, a judge can suspend the whole sentence. But on a repeat offense, a judge can suspend only 55 days of the 60-day minimum sentence.
