DUI in Utah
State-specific overview · Criminal Law
Utah enforces a strict 0.05% BAC threshold for drivers 21+, the lowest in the nation, with zero tolerance for underage drivers.
How Utah treats DUI
Utah Code § 41-6a-502 sets the legal limit at 0.05% BAC for drivers age 21 and older, significantly lower than the federal standard. Drivers under 21 face DUI charges at any detectable BAC level (zero tolerance). Utah also mandates substance abuse assessment and treatment for most DUI offenders, and first convictions typically include jail time, fines, and license suspension.
The general definition of DUI
Driving under the influence of alcohol or drugs, a serious criminal offense.
DUI stands for Driving Under the Influence and means operating a vehicle while impaired by alcohol, drugs, or both. You can be charged with DUI even if your blood alcohol level is below the legal limit if your driving is noticeably impaired. Penalties vary by jurisdiction and whether it's a first or repeat offense, but typically include fines, license suspension, jail time, and mandatory alcohol education programs. A DUI conviction has lasting effects on insurance rates, employment, and your driving record.
