A DUI follows you long after the suspension ends. Utah adds years of alcohol-restricted status, often requires an ignition interlock device (IID), and can impound, or even take, the vehicle.

Know the rule

After action on your license for an alcohol-related offense, you're placed on alcohol-restricted status for 2, 3, 5, or 10 years, depending on the number and type of offenses. Automobile homicide or felony DUI brings lifetime status.

Handbook p. 62 ↗

Alcohol-restricted status begins with a revocation or suspension for:

  • DUI, alcohol-related reckless driving, or impaired driving
  • Automobile homicide or a per se arrest
  • Refusing a chemical test
  • Driving with alcohol while alcohol-restricted
  • Driving without an IID while IID-restricted
Handbook p. 62 ↗

Know the rule

After reinstatement you keep full privileges, but driving with any measurable alcohol during the restricted period means a one-year revocation.

Ignition interlock (IID) restriction

Ignition interlock (IID) restriction
OffenseIID required for
First DUI (21 or older at arrest)18 months
First DUI, under 21 at arrest3 years
2nd+ DUI, impaired, alcohol reckless, or refusal2 years
Felony DUI3 years
Automobile homicide10 years
Handbook p. 63 ↗

Know the rule

An IID-restricted driver's privilege is suspended until an IID is installed and the reinstatement fee paid. Removing the IID before the period ends re-suspends the privilege.

Handbook p. 63 ↗

Know the rule

Driving without a required IID: the vehicle may be impounded, and a conviction brings a one-year revocation plus an extra two-year IID restriction.

60 days

How often the IID must be monitored; each missed check or attempt to start with alcohol adds another 60 days

Handbook p. 63 ↗

Know the rule

After a DUI arrest the officer may impound the vehicle or motorboat. The DMV notifies the owner, who pays towing, storage, and administrative fees for release. An unclaimed vehicle is sold, and the court may order the arrested person to pay.

Handbook p. 63 ↗

Know the rule

A repeat offender convicted of DUI, drugs in the body, or automobile homicide, with a prior felony-level offense after May 1, 2009, may have the vehicle forfeited and sold.

Handbook p. 64 ↗

Interdicted person

A DUI offender a court bars from buying alcohol (required after an extreme DUI). Their license or ID carries a red 'NO ALCOHOL SALE' banner.

Handbook p. 4 ↗

Put it into practice

A 20-year-old convicted of a first DUI must drive only vehicles with an IID for 3 years, not 18 months, because he was under 21 when arrested. If he misses a 60-day monitoring check, the requirement grows by 60 days.
