Utah Ignition Interlock DUI Laws

Information on Utah DUI and Ignition Interlock Laws

Utah DUI laws require that all persons convicted of Driving Under the Influence (DUI) must have an ignition interlock device installed in their vehicle.

Depending on how severe the offense is in Utah, your license will either be suspended (i.e. your driving privileges will be temporarily taken away by the DMV) or revoked (i.e. your license is taken away by the court and you must apply for a new one, including tests)

Your license will be suspended for most DUI offenses, as well as for some reckless or unlawful conduct. For a 2nd or subsequent DUI conviction, manslaughter or negligent homicide while driving, and other serious offenses, your license will be revoked.

Generally, the interlock must be installed for 18 months for a driver over 21, and three years for a driver under 21. Those with prior DUI offenses, a violation related to an already-installed interlock, and those who refuse a chemical test or commit some other violations will be required to use an interlock for three years. Felony DUIs require an interlock for six years, and an automobile homicide will result in a 10-year interlock restriction.

When you are arrested in Utah, your license will be confiscated and replaced with a temporary license that expires in 29 days and your vehicle will likely be impounded. If you are ordered to install an interlock and are caught driving without one, you could be sentenced to jail and face fines of up to $1940, lose your license for one year and receive an interlock restriction for an additional three years.

NOTE: Utah is the only state where the per se limit is less than .08. If you take a breath, blood, or urine test for the presence of alcohol and your blood alcohol concentration (BAC) is .05 or higher, you are presumed to be driving under the influence (DUI).


Every situation and state is unique, please consult with your attorney or your state licensing authority to confirm your requirements and obligations.
