All states have laws against boating under the influence (BUI), which make it a crime to operate a boat or watercraft on a public waterway while under the influence of alcohol or drugs.
In Utah, operating a boat or watercraft under the influence of alcohol or drugs is illegal, similar to driving a vehicle while impaired. The state's BUI (Boating Under the Influence) laws are outlined in Utah Code Section 76-9-702. The law states that an individual may not operate or be in actual physical control of a boat if they have a blood or breath alcohol concentration of .08 grams or greater, which is the same legal limit for driving a vehicle. Additionally, it is also a crime to operate a boat if one is under the influence of alcohol, drugs, or a combination of both to a degree that renders the person incapable of safely operating the boat. Penalties for BUI in Utah can include fines, jail time, community service, and mandatory educational classes on the dangers of alcohol and drugs. The state may also suspend or revoke boating privileges. Enforcement is typically carried out by the Utah Division of State Parks and Recreation and other law enforcement agencies.
