What Are the Utah DUI Laws?

Created by FindLaw's team of attorney writers and editors.

Diving under the influence (DUI), also referred to as driving while intoxicated (DWI) in some states, is a serious offense across the United States. Under Utah's DUI laws, anyone in physical control of a vehicle while having a blood alcohol concentration (BAC) of 0.05% or higher has committed a DUI offense. Utah's DUI statutes also make it illegal to operate a vehicle while under the influence of any drug that prohibits the offender from safely operating a vehicle. The following chart provides a brief overview of Utah's DUI laws.
