In Utah, what is the legal blood alcohol concentration (BAC) limit at which an adult non-commercial driver is considered driving under the influence (DUI)?
The answer
Answer: D. Utah law establishes a statutory blood alcohol concentration (BAC) limit of 0.05 percent for non-commercial drivers aged 21 and older, which is the strictest standard in the United States. Operating a motor vehicle with a BAC of 0.05 percent or higher constitutes driving under the influence.
