First Offense DUI/DWUI in Wyoming

Conviction of a first DUI (sometimes referred to as Driving While Under the Influence -- DWUI) in Wyoming will result in criminal and administrative penalties.

Administrative Penalties

First offense DUI/DWUI arrests require mandatory administrative license suspension of at least ninety (90) days. Treatment or substance abuse assessment is not a prerequisite towards reinstatement of license for first offense DUI cases in Wyoming.

If a driver’s blood alcohol content (BAC ) is higher than .15 in a first offense arrest, the driver may be subject to six (6) months of mandatory ignition interlock device following reinstatement of license. Drivers with BAC lower than .15 may still be subject to ignition interlock device mandates, pending the case-specific nature of their case, but Wyoming criminal statutes do not mandate interlock device use for first offenders

Plea Options

Wyoming does not prohibit reduction of DUI charges to lesser criminal offenses. Likewise, defendants in DUI cases are free to work towards outright dismissal of the charges, as well as negotiate favorable plea bargain deals with prosecutors. All of these activities should be done only in light of the case-specific nature of each DUI case, alongside the representation and insight of a Wyoming DUI lawyer.
