How drunk does someone have to be before they can be charged with a DUI?

In Utah, it is illegal to operate a vehicle while “impaired” by the effects of alcohol or drugs. Under Utah’s “Implied Consent” law, you automatically give your consent to take a breathalyzer test if an officer suspects you of driving while under the influence (DUI).
