Wyoming DUI CDL Consequences: What Commercial Drivers Face

A first-offense DUI hits harder when you hold a Commercial Driver's License. While non-CDL drivers in Wyoming can apply for a probationary license or ignition interlock restricted license to keep driving during their suspension, commercial drivers get no such option. The consequences are career-altering, and they kick in whether the arrest happened in your personal vehicle or behind the wheel of a semi.

The Mandatory 1-Year CDL Disqualification

Under Wyoming Statute § 31-7-305, a first-offense DUI or chemical test refusal triggers an absolute 1-year disqualification of your CDL privileges. This is a federal standard that Wyoming enforces without exception.

The disqualification applies regardless of the circumstances:

• Arrested in your personal car: The CDL disqualification still applies. Wyoming law does not distinguish between commercial and personal vehicle DUI arrests when imposing CDL consequences.
• BAC of 0.04% or higher in a commercial vehicle: Commercial drivers face a lower threshold that can trigger the administrative CDL consequences, even though the standard adult threshold is 0.08%.
• Chemical test refusal: Refusing the post-arrest evidentiary test at the station triggers the same 1-year CDL disqualification, on top of the 6-month administrative license suspension.

There is no probationary CDL, no restricted commercial driving permit, and no interlock option that allows you to operate a commercial motor vehicle during the disqualification period.

Deferred Prosecution Does Not Protect Your CDL

Many first-offense DUI defendants in Wyoming pursue deferred prosecution under W.S. § 7-13-301, which can ultimately dismiss the criminal charge and prevent a permanent conviction on your record. For non-CDL holders, this is a powerful tool.

For CDL holders, the administrative CDL disqualification still applies even if you successfully complete deferred prosecution. The criminal court and WYDOT's administrative track operate independently. A criminal dismissal does not undo the administrative consequence to your commercial driving privileges.

What This Means for Your Career

The practical fallout of a 1-year CDL disqualification in Wyoming is severe:

• Employment disruption: You cannot perform commercial driving that requires an active CDL during the disqualification. Whether your employer can retain you in another role depends on the employer and its insurance requirements.
• Reporting obligations: Ask your employer or a CDL attorney which reporting duties apply to your arrest, conviction, license suspension, or disqualification. Do not assume that the arrest date alone starts a 30-day employer-notice deadline.
• Future employment: Even after reinstatement, the DUI will appear on your driving record within Wyoming's 10-year lookback window, making it harder to pass carrier background checks.

After the Disqualification: Getting Your CDL Back

Once the 1-year period ends, reinstatement is not automatic. You will need to:

1. Complete all criminal court requirements (fines, assessment, treatment programs, probation conditions)
2. Satisfy the administrative suspension requirements (which may include SR-22 insurance filing for 3 years)
3. Pay the $50 WYDOT reinstatement fee
4. Verify that your SR-22 filing is current and on file with WYDOT
5. Confirm with WYDOT whether any CDL renewal or testing step applies before you resume commercial driving

Protecting Your Next Steps

The 20-day deadline to request an administrative hearing with WYDOT applies to CDL holders the same as everyone else. Filing that hearing request buys you time by staying the suspension while the hearing is scheduled, though it does not affect the separate CDL disqualification.
