In Utah, evidence that an operator of a vessel is boating under the influence includes having a blood alcohol concentration (BAC) of 0.08% or higher, which is the legal limit. Additionally, observable signs such as impaired motor skills, slurred speech, or erratic navigation can indicate impairment. Officers may also consider the vessel's operation and any accidents or incidents that arise as a result of the operator's condition. Overall, a combination of BAC levels and behavioral observations may lead to a boating under the influence charge.
