Utah DUI Defense Guide — Charges & Options
DUI basics, court steps, and what happens next
A DUI arrest triggers two separate proceedings that run at the same time. The criminal case decides guilt, penalties, and your record. The administrative case decides whether your license is suspended — often on a much shorter deadline. Missing a step in one track can limit your options in the other, which is why understanding both paths from the start matters.
The two tracks: criminal and administrative
Track 1: Criminal prosecution
The criminal case is a court proceeding where the state must prove DUI beyond a reasonable doubt. Utah's per se BAC limit is 0.05 §41-6a-502, but you can also be charged based on impairment regardless of BAC. A first offense is classified as a Class B misdemeanor; elevated to Class A if bodily injury, wrong-way driving, or passenger under 16.
Track 2: Administrative license action
The administrative action is handled separately from the criminal case. It can result in license suspension even if the criminal case is eventually dismissed. You have a short statutory window applies to request a hearing — confirm the current deadline with a lawyer to request a hearing to contest the suspension.
What triggers enhanced penalties
- Bodily injury
- Passenger under 16 (or under 18 if driver is 21+)
- Wrong-way driving on highway
- Prior felony DUI or automobile homicide conviction
Implied consent and chemical testing
Utah has an Implied consent law: by driving on Utah roads, you have implicitly consented to chemical testing when lawfully arrested for DUI. Refusing the test carries its own consequences: 18-month license revocation (drivers 21 or older); 36 months if the driver had a qualifying prior DUI conviction or license sanction (including a prior refusal) within the preceding 10 years; drivers under 21: until age 21 or two years (36 months with a qualifying prior), whichever is longer. In Utah, refusal to submit to chemical testing is admissible as evidence at trial.
BAC thresholds that matter
| Category | BAC Limit | Consequence | |
|---|---|---|---|
| Standard per se | 0.05 §41-6a-502 | DUI charge without other evidence of impairment | |
| Enhanced penalty | no separately codified enhanced BAC tier — higher BAC is an aggravating factor at sentencing §41-6a-502 | Higher minimum penalties and longer license suspension | |
| Under 21 | 0.00 (any detectable amount) | Zero tolerance violation | |
| Commercial (CDL) | a lower BAC limit applies under a separate licensing statute — confirm the current threshold with a lawyer §49 C.F.R. § 383.51 | CDL disqualification |
Why timing matters most
DUI cases are unusually time-sensitive. The administrative hearing deadline begins running from the date of arrest or notice — not from the first court date. Evidence (dashcam footage, witness recollections, calibration records) can deteriorate. Early attorney involvement can preserve options that disappear with delay.
