Utah DUI Types and Penalties: A Complete Reference

← Back to Blog

Utah has one of the most comprehensive DUI statutory frameworks in the country, with multiple offense types carrying distinct consequences. This reference covers every category of DUI-related charge under Utah law — from the standard DUI to automobile homicide — with the applicable statute, offense level, minimum penalties, and license consequences for each.

The Penalty Chart

Key Distinctions Explained

Standard DUI vs. Impaired Driving

A standard DUI under § 41-6a-502 requires proof that the driver had a BAC of 0.05 or above, or that the driver was impaired to the degree that they could not safely operate the vehicle. Impaired driving under § 41-6a-502.5 is a lesser offense that captures driving impaired to any degree — meaning even slight impairment is sufficient. Impaired driving is commonly offered as a plea reduction. It carries no mandatory minimum jail, no mandatory minimum fine, and no mandatory license suspension, though courts retain discretion on all of these.

Metabolite DUI

Utah Code § 41-6a-517 creates an offense for operating a vehicle with any measurable controlled substance or metabolite in the body. No impairment is required. A person can be charged under this statute days or weeks after last using a substance, simply because the metabolite remains detectable. The statute applies to prescription medications as well as illegal drugs. This is one of the more aggressive provisions in Utah's DUI framework and is worth challenging on the specific facts of each case.

Automobile Homicide

Utah Code § 76-5-207 makes automobile homicide a second degree felony in every category. Subsection (2)(a) covers operating a vehicle in a negligent or criminally negligent manner while impaired or with a BAC of 0.05 or greater. Subsection (2)(b) covers operating in a criminally negligent manner with any measurable controlled substance. Under § 76-5-207(3)(a), the penalty is imprisonment of not less than five nor more than fifteen years. Under § 76-5-207(7), the court may impose three to fifteen years if it details on the record why a shorter sentence is in the interest of justice. The distinction between simple negligence and criminal negligence matters for the (2)(a) versus (2)(b) charging path and for sentencing argument, even though the statutory range is the same.

The Expungement Bar

A DUI conviction — including a conviction for the metabolite offense under § 41-6a-517 — is not expungeable in Utah. Utah Code § 77-40a-102 specifically excludes DUI offenses from expungement eligibility. An impaired driving conviction under § 41-6a-502.5 may be expungeable after the applicable waiting period. This distinction is one of the most consequential differences between a DUI conviction and a reduced plea, and it matters for employment, professional licensing, and housing for the rest of your life.

DUI Causing Bodily Injury or Serious Bodily Injury

Utah Code § 76-5-102.1, titled "Negligently operating a vehicle resulting in injury," is the statute that applies when a DUI driver causes bodily injury to another. The elements under § 76-5-102.1(2) are operating a vehicle in a negligent manner causing bodily injury while either at or above a 0.05 blood or breath alcohol concentration or while under the influence of alcohol or drugs, or operating in a criminally negligent manner causing bodily injury while having any measurable amount of a controlled substance in the body.

The base offense is a class A misdemeanor under § 76-5-102.1(3)(a)(i). It elevates to a third degree felony under § 76-5-102.1(3)(a)(ii) when the driver has two or more DUI-related prior convictions as defined in § 41-6a-501(2)(a) within 10 years of the current offense, under § 76-5-102.1(3)(a)(iii) when the driver has any prior felony DUI-related conviction at any time (no lookback limit for felony priors), or under § 76-5-102.1(3)(a)(iv) when the bodily injury meets the statutory "serious bodily injury" threshold. "Serious bodily injury" is defined in § 41-6a-501(1)(i) as bodily injury that creates or causes serious permanent disfigurement, protracted loss or impairment of the function of any bodily member or organ, or a substantial risk of death.

Under § 76-5-102.1(3)(b), the statute creates a separate offense for each victim suffering bodily injury, regardless of whether the injuries arise from the same episode of driving. A single incident can therefore produce multiple counts.

Boating and Off-Highway Vehicle DUIs

Many people do not realize that operating a boat or an ATV while under the influence in Utah is the same criminal offense as driving a car under the influence. Utah Code § 41-6a-501(1)(l) defines "vehicle" and "motor vehicle" for purposes of the DUI statutes to expressly include a motorboat as defined in § 73-18-2 and an off-highway vehicle as defined in § 41-22-2. The result is that § 41-6a-502 and the sentencing schedule in § 41-6a-505 apply to motorboat and OHV operation the same way they apply to a car. A first offense is a class B misdemeanor, a second offense within ten years is a class A misdemeanor, and a third or subsequent within ten years is a third degree felony. Because § 76-5-102.1 also borrows the § 41-6a-501 vehicle definition, a serious-injury crash on a boat or an ATV under the influence is charged under § 76-5-102.1 the same way it would be charged after a car crash.

Aggravating Factors That Increase Penalties

Several factors operate as statutory enhancements or as practical penalty multipliers on top of the base offense level. Recognizing which apply to a given case is one of the first jobs of the defense.

BAC of 0.16 or higher (Extreme DUI)

Utah Code § 41-6a-505(1) creates a separate enhanced first-offense penalty when there is admissible evidence of a blood or breath alcohol concentration of 0.16 or higher. Even on a first offense the court must impose either a minimum 5-day jail sentence or a minimum 2-day jail sentence plus at least 30 consecutive days of home confinement with electronic monitoring. Under § 41-6a-505(13), a conviction with admissible BAC of 0.16 or higher also obligates the court to order treatment plus one or more of the following — an ignition interlock system under § 41-6a-518, an ankle-attached continuous transdermal alcohol monitor, or home confinement through electronic monitoring — unless the court describes on the record why those orders are not appropriate.

Minor passenger

The presence of a passenger under sixteen years of age elevates the offense from a class B misdemeanor to a class A misdemeanor under the table above. § 41-6a-505 also creates a separate offense for each child passenger under 16 in the vehicle at the time of the offense.

Refusal of the chemical test

Refusing the post-arrest chemical test is not itself a separate criminal charge under § 41-6a-502, but a refusal under § 41-6a-520.1 is itself a "prior conviction" for enhancement purposes under § 41-6a-501(2)(a)(ix), and refusal triggers a longer administrative license suspension at the Driver License Division. The interaction between refusal and the criminal case is covered in detail on the DLD hearing and booking pages of this site.

Prior felony DUI

The 10-year lookback in § 41-6a-505 and § 76-5-102.1 applies to misdemeanor DUI priors. Under § 41-6a-505 and § 76-5-102.1(3)(a)(iii), a prior felony DUI or felony automobile-homicide conviction is treated as an enhancing prior at any time after the prior conviction, without a 10-year limit. A new DUI committed at any time after any prior felony DUI-related conviction is therefore itself a third degree felony. This is the most consequential criminal-history factor in a DUI case.

Long-Term Collateral Consequences

Statutory minimum jail and fines understate the long-term cost of a DUI conviction. The collateral effects can outlast the underlying sentence by years.

Ignition Interlock Device

Ignition interlock devices are governed by § 41-6a-518 and the broader sentencing requirements in § 41-6a-505. The court is required to order an interlock as a condition of probation in most DUI sentences, and an interlock is required as a condition of license reinstatement in most cases involving a conviction or a refusal. The interlock period varies with offense number, BAC, and other statutory factors. The driver pays for installation, monthly monitoring, and removal. Driving any vehicle without a required interlock is a separate offense.

Alcohol-restricted driver

Under § 41-6a-529, a person convicted of a misdemeanor DUI under § 41-6a-502, a conviction for negligently operating a vehicle resulting in injury under § 76-5-102.1, alcohol-related reckless driving under § 41-6a-512, or impaired driving under § 41-6a-502.5 is an "alcohol restricted driver" for two years from the date of the conviction. Longer periods apply to felony DUIs and to certain second offenses. Under § 41-6a-530, an alcohol-restricted driver may not operate any vehicle with any measurable alcohol in the body, which is a separate offense from a per-se DUI.

Professional licensing

Utah's Division of Occupational and Professional Licensing reviews convictions separately from the criminal court. A DUI conviction can affect licensure in healthcare, law, real estate, education, commercial transportation, security, and any field requiring a background check. The conviction's non-expungeability magnifies this exposure.

Travel and immigration

A DUI conviction can affect admissibility to Canada under Canadian immigration law and can affect immigration status, visa applications, and naturalization eligibility for non-citizens. The specific consequences are determined by federal immigration authorities and by the destination country, not by Utah law, but the underlying Utah conviction is the trigger.

Insurance

Auto insurance premiums rise significantly after a DUI conviction and the higher rates typically run for multiple policy years. Some insurers will not renew at all. SR-22 financial responsibility filings are often required as a condition of license reinstatement.
