Wyoming DUI License Suspension: How Long and What to Expect

The Suspension Length Depends on What Triggered It

A first-offense DUI in Wyoming carries different administrative suspension periods depending on your chemical test result:

• BAC 0.08% to 0.14%: 90-day administrative suspension
• BAC 0.15% or higher: 90-day suspension with mandatory ignition interlock
• Chemical test refusal: 6-month administrative suspension
• Under 21, BAC 0.02% or higher: Administrative suspension under the implied consent youth provisions

These suspensions come from WYDOT, not the court. The criminal court can also order a separate suspension as part of sentencing, but Wyoming law credits time already served under the administrative suspension — so you won't serve both periods back to back.

When the Suspension Actually Starts

The timeline depends on whether you filed a hearing request within the 20-day window:

If you filed a hearing request: The suspension is stayed until the Office of Administrative Hearings (OAH) rules. The OAH must hold the hearing within 45 days of receiving the request. If the hearing officer upholds the suspension, it starts from the date of the ruling.

If you didn't file: The suspension begins automatically on day 31 after the notice date (typically the arrest date) — the day after your temporary driving permit expires.

What You Can and Can't Do During Suspension

Driving on a suspended license in Wyoming is a separate misdemeanor carrying 7 days to 6 months in mandatory jail time. There's no leniency for "I didn't know" or "I had to get to work."

But Wyoming offers two restricted driving options for eligible first-time offenders:

Probationary (hardship) license — Available if your BAC was between 0.08% and 0.14% (no test refusal). Restricts driving to essential travel: work, school, medical appointments, and court appearances. Requirements include SR-22 insurance, a substance abuse assessment, and fees totaling about $70 ($15 record review + $55 issuance).

Ignition Interlock Restricted License (IIRL) — Required for BAC of 0.15% or higher, or if you refused testing. Allows unrestricted driving as long as every vehicle you operate has a certified interlock device installed. Refusal drivers must serve a 45-day hard suspension before they can even apply. Costs include a $100 WYDOT administrative fee, $50 reinstatement fee, plus device installation ($70–$150) and monthly lease ($70–$150).

The Criminal Court's Role in Suspension

Beyond the administrative suspension, the circuit court judge can impose a license suspension as part of a criminal sentence. Wyoming law credits time already served under the administrative suspension toward the court-ordered suspension, so the periods do not necessarily stack.

If you receive a deferred prosecution under W.S. § 7-13-301 and successfully complete probation, the criminal charge gets dismissed — but this has no effect on the administrative suspension. WYDOT's licensing record is independent of the court's disposition.

Avoiding a Suspension Entirely

The only way to prevent the administrative suspension is to file a hearing request within 20 days and win at the OAH hearing. Success requires showing that the officer lacked reasonable suspicion for the stop, lacked probable cause for the arrest, or failed to follow proper testing procedures.

These hearings are technical and fact-specific. Many people handle them without an attorney, but having one can make a difference if the evidence involves calibration records or procedural violations.
