What Utah law requires
Utah's ignition interlock, SR-22, and reinstatement rules are set by the statute and agency rules cited below. The values in the tables on this page are taken from those sources and are not interpretations of how they apply to any particular case.
Primary source: Utah Code § 41-6a-518
Ignition interlock requirement
| Item | Utah rule |
|---|---|
| IID on first offense | Required |
| Minimum IID period, first offense | 18 months |
| Minimum IID period, repeat offense | 2 years (second offense within 10 years of a prior conviction, § 41-6a-518.2(2)(b)(ii)); 3 years for a felony DUI; 4 years for automobile homicide |
Two overlapping provisions. Utah Code § 41-6a-518(2)(a): unless the court determines and states on the record that an interlock is not necessary for community safety and in the best interest of justice, the court shall require that any person convicted under § 41-6a-502 and granted probation drive only a vehicle with a certified ignition interlock during probation. Independently, § 41-6a-518.2(1)(b)(ii)(A) and (2)(b)(i) make any person convicted under § 41-6a-502 an 'interlock restricted driver' for 18 months from proof of installation and reinstatement (three years if under 21 per DLD). § 41-6a-518(2)(e) excludes convictions that do not involve alcohol, and § 41-6a-518.2(8) allows the Division to remove the restriction if the offense did not involve alcohol.

SR-22 requirement
An SR-22 is a certificate an insurer files with the state to confirm that a driver carries the liability coverage the state requires. Some states use an FR-44 or a different form for alcohol-related offenses; where Utah does, the sources below say so.
| SR-22 filing required after a DUI | No |
|---|---|
| Filing period | Not applicable |
No DUI-specific SR-22 requirement was found on official sources. The Utah Driver License Division's SR22 page lists the circumstances that require an SR-22 filing — a conviction for driving without insurance, an uninsured vehicle involved in an accident, a court order for damages from an uninsured accident, and Driving Privilege Card holders — and does not list DUI; the DLD DUI, IID and reinstatement pages likewise do not mention an SR-22 for DUI. When an SR-22 is required, Utah Code § 41-12a-411 and DLD state it is maintained for three years.
What the source says (5)
- SR-22 filing required after a DUI
“In the State of Utah, a conviction for driving without insurance or without proof of insurance mandates the suspension of the driver's license and requires the provision of an SR22 filing to the Driver License Division (DLD).”
- SR-22 requirement
“Other circumstances necessitating an SR22 include: If a vehicle registered under your name is uninsured and is involved in an accident. A court order for damages resulting from an uninsured accident.”
- sr22Note_duration
“shall maintain that proof with the department for a period of three years from the date the filing of proof was last requested”
- sr22Note_duration_dld
“The requirement for an SR22 typically extends for a period of three years from the date of conviction.”
- sr22Note_dpc
“Failure to provide satisfactory proof of owner's or operator's security if you possess a Driving Privilege Card (DPC).”

Exemptions and special cases
Four questions readers ask once an interlock is ordered — motorcycles, employer vehicles, medical inability to give a breath sample, and reduced-cost programs — answered as Utah's interlock program page or statute states them.
| Question | Utah rule |
|---|---|
| Motorcycles | A device may be installed on a motorcycle The Driver License Division states that an interlock-restricted driver must not drive any vehicle, including motorcycles, without an ignition interlock device installed. Neither Utah Code § 41-6a-518 nor § 41-6a-518.2 mentions motorcycles; DLD does not list a motorcycle-specific certified device. What the source says“When a driver is ignition interlock restricted, they must not drive any vehicle, including motorcycles, without an ignition interlock device installed.” |
| Employer-owned vehicle | Exempt with conditions Utah Code § 41-6a-518(7): a probationer required in the course and scope of employment to operate a vehicle owned by the employer may drive it without a system only if the vehicle is used in the course and scope of employment, the employer has been notified that the employee is restricted, and the employee carries 'employer verification' while driving. Employer verification (§ 41-6a-518(1)(b)) is written verification that the employer knows the employee is interlock restricted, the vehicle is not made available for personal use, the business is not wholly or partly owned or controlled by the employee, the employer's auto insurer is aware, and the employee has been added to the employer's policy. No exemption applies to an employer vehicle made available for personal use, and a vehicle owned by a business the probationer owns or controls does not qualify. § 41-6a-518.2(6)-(7) makes the same facts an affirmative defense to the class B misdemeanor of driving without a system. DLD lists an 'Ignition Interlock Employment Exemption Affidavit' as a reinstatement document for a restricted driver who does not own a vehicle and will not operate a vehicle owned by another individual. What the source says“If a probationer is required in the course and scope of employment to operate a motor vehicle owned by the probationer's employer, the probationer may operate that motor vehicle without installation of an ignition interlock system only if:” |
| Unable to provide a breath sample | Available Utah Code § 41-6a-518.2(9): an individual with an interlock restriction who has a medical condition that prohibits providing a deep lung breath sample may petition the Driver License Division for removal of the restriction, supported by physician documentation describing the condition; if the division establishes the inability, it may remove the restriction. DLD describes this as the IID Medical Exemption: provide medical documents, have the information reviewed by the medical advisory board, then meet all reinstatement requirements including fees; a driver approved for the medical exemption is not eligible for DUI Early Reinstatement. What the source says“An individual with an ignition interlock restriction may petition the division for removal of the restriction if the individual has a medical condition that prohibits the individual from providing a deep lung breath sample.” |
| Reduced-cost / indigent program | Available Statutory court indigency waiver, not a named program. Under Utah Code § 41-6a-518(6) the probationer pays the reasonable costs of leasing/buying, installing, maintaining and monitoring the system, but may not be excluded from the section for inability to pay if the probationer files an affidavit of indigency under § 78A-2-302 and the court finds the probationer indigent; in lieu of waiving the entire cost the court may order partial or installment payments; the ignition interlock provider covers the cost of court-ordered waivers. The DLD IID page does not mention reduced fees. What the source says“In lieu of waiver of the entire amount of the cost, the court may direct the probationer to make partial or installment payments of costs when appropriate. (d) The ignition interlock provider shall cover the costs of waivers by the court under this Subsection (6).” |
| Removal where the offense did not involve alcohol | Utah Code § 41-6a-518.2(8): an individual may petition the division for removal of the restriction if the offense did not involve alcohol; the division may remove the restriction if it establishes that fact. What the source says“An individual with an ignition interlock restriction may petition the division for removal of the restriction if the individual's offense did not involve alcohol.” |
| Non-resident verification | DLD lists, as a reinstatement alternative for a person who is not a Utah resident, paying the reinstatement fee and verifying no vehicle is owned in Utah through electronic verification of licensure (or pending licensure) in the state of residence. What the source says“Payment of a reinstatement fee and, if you are not a resident of Utah, verify you do not own a vehicle in Utah by electronic verification that you are licensed in another state of residence, or you are in the process of obtaining a license in your state of residence.” |
| Early device removal | If the IID is removed before the restriction period ends, the license is re-suspended until a device is installed and an additional reinstatement fee is paid. What the source says“If the IID is removed prior to the ending date of the ignition interlock restriction period, the license will be re-suspended until an IID is installed and an additional reinstatement fee is paid.” |
