Wyoming requires a 90-day hard suspension before DUI drivers can apply for a probationary license. If you need to drive to work during your suspension, here's what Wyoming DOT requires and what most drivers miss about route documentation and ignition interlock compliance.
When Wyoming allows probationary license applications for work driving
Wyoming requires a 90-day hard suspension before first-offense DUI drivers can apply for a probationary license. The 90-day clock starts on your conviction date, not the date you file your application or complete DUI education.
During those 90 days, no driving is allowed for any purpose. No commute exception, no employer letter override, no hardship provision. Wyoming statute W.S. 31-5-233 makes this mandatory.
Second-offense DUI carries a longer hard suspension before probationary eligibility. Points-based suspensions and uninsured-driving cases do not face a fixed hard period in most instances, but verification through Wyoming Driver Services is necessary before filing.
What Wyoming calls the work-purposes restricted license and what it covers
Wyoming uses the term Probationary License for its restricted-driving program. This is not a temporary permit or a grace period extension. It is a separate license issued after your suspension begins, with specific route and purpose restrictions.
Approved purposes typically include: driving to and from work, driving during work hours if your job requires it, driving to court-ordered DUI education or treatment, driving to medical appointments, and driving to school if you are enrolled. Wyoming Driver Services defines the exact purposes when your probationary license is approved.
Your employer must provide a signed letter verifying your job location, work hours, and whether your job requires driving during work. Most county clerks in Wyoming do not notarize employer letters, but the letter must include the employer's contact information so Driver Services can verify if needed.

Ignition interlock requirement for DUI probationary licenses in Wyoming
All DUI-related probationary licenses in Wyoming require installation of an ignition interlock device (IID) before the probationary license is issued. This is codified at W.S. 31-5-233 and applies to first and subsequent offenses.
You must enroll with a Wyoming DOT-approved IID vendor, have the device installed in the vehicle you will drive, and provide proof of installation to Driver Services before your probationary license application is processed. Wyoming-approved vendors include Smart Start, Intoxalock, and LifeSafer.
Monthly IID costs typically range from $70 to $100, including calibration. Installation fees run $50 to $150. These costs are separate from your probationary license application fee and your SR-22 insurance filing. If you drive a vehicle without an installed IID during your probationary period, your probationary license is revoked immediately and your full suspension period restarts.
SR-22 insurance filing setup required for Wyoming probationary license approval
Wyoming requires an SR-22 filing before Driver Services will approve your probationary license application. The SR-22 is a form your insurance carrier files directly with Wyoming DOT certifying that you carry at least Wyoming's minimum liability coverage: $25,000 per person for bodily injury, $50,000 per accident, and $20,000 for property damage.
You cannot file an SR-22 yourself. Your carrier files it electronically. Wyoming Driver Services receives the filing within 24 to 48 hours in most cases. Do not submit your probationary license application until your SR-22 filing is confirmed active.
If you do not own a vehicle, you need a non-owner SR-22 policy. This covers liability when you drive a borrowed or employer-owned vehicle. Non-owner SR-22 premiums in Wyoming typically range from $40 to $80 per month for drivers with one DUI. Owner SR-22 premiums with one DUI typically range from $140 to $220 per month, depending on your age, county, and vehicle.
How to apply for a Wyoming probationary license and what documentation Driver Services requires
Wyoming probationary license applications are submitted to Wyoming Driver Services in Cheyenne. Applications are not accepted online. You must submit by mail or in person at the Cheyenne headquarters: 5300 Bishop Blvd, Cheyenne, WY 82009.
Required documents: completed probationary license application form (available on the Wyoming DOT website), proof of SR-22 insurance filing, proof of ignition interlock installation, employer verification letter stating your job location and work hours, court order or suspension notice showing your conviction and suspension dates, and payment for the $50 reinstatement fee. Wyoming charges a separate $50 fee per suspension, so drivers with multiple simultaneous suspensions may owe $100 or more.
Processing time is typically 10 to 15 business days after Driver Services receives a complete application packet. Incomplete applications are returned without processing, adding weeks to your timeline. Call Driver Services at 307-777-4800 before mailing to confirm current documentation requirements and fee amounts.
What happens if you drive outside approved routes or hours on a Wyoming probationary license
Your probationary license restricts you to specific purposes: work, DUI education, medical appointments, and any other purpose Driver Services approved in your application. Driving outside those purposes or outside your approved hours is treated as driving under suspension in Wyoming.
First violation of probationary license terms triggers immediate revocation of the probationary license and restart of your full suspension period from the violation date. You also face a separate misdemeanor charge for driving under suspension, which carries up to six months in jail and fines up to $750.
Wyoming law enforcement can verify probationary license restrictions during traffic stops. If you are pulled over for any reason and the officer determines you are outside your approved route or time window, the probationary license is revoked on the spot. There is no grace period and no administrative appeal before revocation takes effect.
What CDL holders need to know about Wyoming probationary licenses and commercial driving
If you hold a Wyoming commercial driver's license (CDL), a probationary license issued for a personal-vehicle DUI does not restore your CDL privileges. Federal law prohibits commercial driving during any suspension period, and probationary licenses are state-level personal-driving exceptions.
You cannot drive commercial vehicles under a probationary license, even if your job requires commercial driving and even if your employer provides a letter. Your CDL remains suspended for the full statutory period regardless of probationary license approval.
After your full suspension period ends and your personal license is reinstated, you must apply separately to reinstate your CDL through Wyoming Driver Services. CDL reinstatement requires proof of SR-22 insurance, completion of any court-ordered DUI treatment, payment of all reinstatement fees, and in most cases a commercial knowledge retest.
