Utah DUI Laws: Penalties, the 0.05 Limit, and Your Rights
Utah has the strictest drunk driving threshold in the country, and the penalties for violating it are serious. Whether you want to understand the law or you were hurt by an impaired driver, here is a plain-English look at Utah DUI laws and what they mean for injury victims.
In Utah, you can be charged with DUI at a blood alcohol concentration of 0.05 percent, the lowest limit in the nation. A first offense is generally a Class B misdemeanor carrying mandatory jail time or community service, fines, and a license suspension. If a drunk driver injures you, that same conduct can also support a civil injury claim for your damages.
Utah’s 0.05 legal limit
Since December 2018, Utah has set its per se DUI limit at 0.05 percent blood alcohol concentration for most adult drivers, lower than the 0.08 standard used in most other states. Commercial drivers face a stricter 0.04 limit, and drivers under 21 are held to a not-a-drop standard. Importantly, you can be charged even below 0.05 if an officer concludes you were too impaired to safely operate a vehicle, including impairment from drugs or prescription medication.
Penalties for a Utah DUI
Utah penalties escalate quickly with repeat offenses and with any injury or death involved. The table below summarizes the general framework, though exact consequences depend on the facts and a judge’s discretion.
| Offense | Classification | Typical consequences |
|---|---|---|
| First offense | Class B misdemeanor | Minimum 48 hours jail or community service, fines, roughly 120-day license suspension, and an ignition interlock requirement |
| Second offense (within 10 years) | Class B misdemeanor | Longer mandatory jail or community service, higher fines, and a longer suspension |
| Third offense (within 10 years) | Third-degree felony | Substantially harsher penalties, including possible prison time |
| DUI causing serious injury or death | Felony | Enhanced criminal charges plus potential civil liability to victims |
A first-offense fine typically starts around $700 before Utah’s statutory surcharges, which can push the real cost significantly higher once fees are added. Drivers also face increased insurance costs and the expense of an ignition interlock device.
Key point. A DUI conviction is a criminal matter handled by the state, but it does not compensate the people the drunk driver hurt. If you were injured, you have a separate right to bring a civil claim for your medical bills, lost wages, and pain and suffering, and a criminal conviction can be powerful evidence in that claim.
Your rights if a drunk driver hurt you
- You can pursue the at-fault driver. Impaired driving is strong evidence of negligence in a civil injury case.
- You may recover full damages. Beyond Utah’s no-fault PIP coverage, serious injuries can open the door to claims for pain, suffering, and long-term losses.
- Punitive damages may apply. Utah law allows punitive damages in cases involving reckless conduct such as drunk driving, on top of your actual losses.
- A criminal case does not limit your claim. You can pursue a civil claim regardless of what happens in the driver’s criminal case.
