Utah's DUI laws are the most restrictive in the United States — with a blood alcohol content limit of 0.05%, mandatory minimum sentences, and an aggressive administrative license suspension process. Whether you have been charged or simply want to understand your rights, this page provides a comprehensive overview of Utah DUI law and what you can expect if charged.
The 0.05% BAC Standard
Effective December 2018, Utah lowered its DUI threshold to 0.05% BAC — the lowest in the country. A 150-pound person can exceed this limit after just one drink. Drivers can also be charged with DUI regardless of BAC if they are impaired by drugs (including prescription medications) or a combination of drugs and alcohol.
Criminal Penalties
A first-offense DUI in Utah is a Class B misdemeanor carrying up to 48 hours mandatory jail (or 48 hours of community service), fines up to $1,000, and a suspended sentence with probation. A second offense within 10 years is a Class A misdemeanor. A third offense within 10 years is a third-degree felony.
Per Se DUI vs. Impairment DUI
Utah has two types of DUI: "per se" DUI (where BAC alone establishes guilt, without proof of actual impairment) and "impairment" DUI (where the prosecution must prove the driver was impaired regardless of BAC). Most DUI charges in Utah are charged under the per se standard.
Frequently Asked Questions
Can I be charged with DUI for prescription drugs?
Yes. Utah law prohibits driving under the influence of any substance — including legally prescribed medications — that impairs the ability to safely operate a vehicle. If your prescription medication affects your driving, you can be charged with DUI even with a valid prescription.
