A second DUI in Utah is a Class A misdemeanor with a minimum 10 days in jail, a 2-year driver license revocation, fines exceeding $2,500, and a mandatory ignition interlock device for 3 years. The 10-year lookback period under Utah Code 41-6a-503 means any prior DUI within the past decade triggers these enhanced penalties.

Key Takeaways
- A second DUI in Utah is a Class A misdemeanor, the highest level of misdemeanor, with up to 1 year in jail.
- Minimum jail time is 10 days, and the court cannot suspend this requirement.
- Driver license revocation lasts 2 years, with no restricted driving privileges for the first year.
- The 10-year lookback period determines whether a prior DUI counts for enhancement.
- Mandatory IID requirement extends to 3 years, with strict compliance monitoring.
A second DUI in Utah carries significantly harsher penalties than a first offense. The state treats repeat offenders with escalating consequences designed to deter further impaired driving. If you have a prior DUI on your record from within the last 10 years, a new arrest will be prosecuted under the enhanced second-offense statute regardless of how much time has passed between the two incidents.
Utah Code 41-6a-503 governs the penalties for second and subsequent DUI convictions. The classification jumps from a Class B misdemeanor for a first offense to a Class A misdemeanor for a second offense. This upgrade brings higher fines, longer jail sentences, and more severe license consequences. In some circumstances involving injury or death, a second DUI can be charged as a felony.

A key difference between Utah’s approach and many other states is that Utah does not offer a “plea down” option for DUI charges in most circumstances. You cannot typically plead a second DUI to a lesser charge such as reckless driving or impaired driving to avoid the mandatory minimums. The Utah Legislature has restricted plea bargaining in DUI cases to ensure that mandatory penalties apply.
What Are the Criminal Penalties for a Second DUI in Utah?
The criminal penalties for a second DUI are substantially more severe than a first offense. The jail minimum increases fivefold, and the fine structure escalates accordingly.
Under Utah Code 41-6a-503(2), a second DUI conviction within 10 years carries:
- Jail: Minimum 10 days, maximum 1 year
- Fine: Minimum $1,500, maximum $2,500, plus surcharges
- License revocation: 2 years (not suspension, but revocation)
- Ignition interlock: Mandatory for 3 years
- Substance abuse evaluation and treatment completion
- Probation: Up to 3 years with intensive supervision
Unlike a first offense where 48 hours of jail can sometimes be substituted with treatment, the 10-day minimum for a second DUI is mandatory and cannot be suspended. This means you will serve jail time regardless of mitigating circumstances.
| Penalty | First DUI | Second DUI |
|---|---|---|
| Misdemeanor class | Class B | Class A |
| Minimum jail | 48 hours | 10 days |
| Maximum jail | 6 months | 1 year |
| Base fine minimum | $700 | $1,500 |
| License action | 120-day suspension | 2-year revocation |
| IID duration | 18 months | 3 years |
How Does the 10-Year Lookback Period Work for a Second DUI?
The 10-year lookback period, codified in Utah Code 41-6a-503, determines whether your current DUI counts as a first or second offense. The court looks back 10 years from the date of the current offense to see if you have any prior DUI convictions.
For purposes of the lookback, the following priors count:
- Any prior Utah DUI conviction under Utah Code 41-6a-502
- Any alcohol-related reckless driving conviction in Utah
- Any DUI conviction from another state
- Any DUI conviction from federal or military court
- Any impaired driving conviction that would constitute DUI in Utah
If your prior conviction is older than 10 years, it does not trigger the enhanced second-offense penalties. However, the court may still consider the older prior as a factor in sentencing within the first-offense range, potentially leading to a harsher sentence within the statutory limits.
The 10-year period runs from the date of the prior offense, not the date of conviction. This means if you were arrested for a first DUI 11 years ago but convicted 10 years and 6 months ago, the lookback is measured from the original offense date, which may fall outside the window.
What Are the Total Costs and Fines for a Second DUI?
The base fine for a second DUI is $1,500. After mandatory surcharges and fees, the court-imposed total approaches $2,500 or more. Utah law adds a 35 percent surcharge, a $115 DUI assessment fee, and court costs ranging from $200 to $400.
Beyond court costs, a second DUI carries substantial additional expenses:
- Ignition interlock for 3 years: $2,500 to $5,400 in total rental and monitoring fees
- DUI school and substance abuse treatment: $500 to $1,000
- License reinstatement fee: $275 to $325 after revocation period
- SR-22 insurance filing: $25 to $50 monthly surcharge on top of increased premiums
- Auto insurance increases: Often 200 to 300 percent increase for 5 years
- Attorney fees: $2,500 to $10,000 depending on case complexity
Total out-of-pocket costs for a second DUI in Utah typically fall between $8,000 and $20,000 when all expenses including insurance increases are factored in over time.
How Long Is License Revocation for a Second DUI?
A second DUI triggers a 2-year driver license revocation. This is different from a suspension. A revocation means your driving privilege is terminated and must be reinstated after the revocation period ends. You cannot simply wait out the time and pay a fee; the DLD must affirmatively reinstate your license.
The Utah Driver License Division administers the revocation. Unlike a first-offense suspension where a restricted license may be available after 30 days, no restricted driving privileges are available during the first year of a second-offense revocation. After the first year, you may qualify for a restricted license that allows driving only for employment, medical care, and substance abuse treatment.
To obtain a restricted license after the first year, you must:
- Install an ignition interlock device
- File an SR-22 certificate
- Complete substance abuse treatment
- Pay all reinstatement fees
- Maintain proof of compliance with court orders
The restricted license is not automatic. You must apply and demonstrate compliance with all conditions. Any violation of the restricted license terms can result in cancellation and a return to full revocation.
What Is the Ignition Interlock Requirement for a Second DUI?
Utah Code 41-6a-518 requires an ignition interlock device for 3 years following a second DUI conviction. The requirement is significantly longer than the 18-month requirement for a first offense.
The IID must be installed on every vehicle you own or drive regularly. The device manufacturers set the threshold, typically requiring a breath sample below 0.025 BAC before the vehicle starts. Random rolling retests during driving prevent tampering.
Compliance is monitored through regular data downloads. Any violations reported to the court can result in extended interlock requirements or additional penalties. Common violations include:
- Failed breath tests above 0.025 BAC
- Missed rolling retests
- Tampering or attempted bypass of the device
- Failure to calibrate on schedule
The Utah Department of Public Safety maintains a list of approved IID vendors. You are responsible for all installation, monthly rental, calibration, and removal fees.
Can a Second DUI Be a Felony in Utah?
While a standard second DUI is a Class A misdemeanor, certain aggravating factors can elevate the charge to a felony. Utah Code 41-6a-503(4) provides that a third DUI within 10 years is a third-degree felony, but a second DUI can also become a felony in specific circumstances.
A second DUI may be charged as a felony if:
- The incident involved serious bodily injury or death of another person
- The driver had a passenger under 16 years old in the vehicle
- The driver was driving on a suspended or revoked license at the time
- The BAC was 0.16 or higher
A felony DUI conviction carries prison time in a state correctional facility rather than jail in a county facility. Felony consequences also include permanent loss of firearm rights, ineligibility for certain professional licenses, and deportation consequences for non-citizens.
Frequently Asked Questions
Does a second DUI require jail time in Utah?
Yes. Utah law mandates a minimum of 10 days in jail for a second DUI. The court cannot suspend this requirement. Unlike a first offense, treatment cannot substitute for the jail time.
How far back does Utah look for prior DUIs?
Utah uses a 10-year lookback period measured from the date of the current offense. Any prior DUI conviction within that window counts for purposes of enhanced penalties under Utah Code 41-6a-503.
Can I get a restricted license after a second DUI?
Not during the first year of revocation. After 12 months, you may apply for a restricted license that permits driving for work, medical care, and treatment. You must install an IID and file an SR-22 to qualify.
Will a second DUI show up on a background check?
Yes. A second DUI is a Class A misdemeanor conviction that appears permanently on criminal background checks. Utah law generally does not permit expungement of DUI convictions.
What happens if I refuse a chemical test on a second DUI?
Refusing chemical testing on a second offense triggers a 2-year license revocation under Utah Code 41-6a-520. The court may also use the refusal as evidence of consciousness of guilt in the criminal case.
Can a second DUI be reduced to reckless driving in Utah?
In most Utah courts, plea bargaining a DUI to reckless driving is prohibited by statute. Utah Code 41-6a-502.5 restricts the reduction of DUI charges in nearly all circumstances, especially for repeat offenders.
Does a second DUI affect my auto insurance?
Yes, significantly. Most insurers consider a second DUI a high-risk indicator. Premiums may increase by 200 to 300 percent. Many insurance companies will non-renew your policy, requiring you to find coverage through a high-risk insurer. An SR-22 filing is mandatory.
How long does the IID stay on after a second DUI?
The mandatory IID requirement for a second DUI is 3 years from the date of conviction. The court may extend the period if compliance issues occur during the monitoring period.
A second DUI in Utah carries escalating consequences that affect every aspect of your life from your freedom and finances to your driving privileges and employment prospects.
