Missouri is a critical state for freight moving east-west along I-70 and I-44. Whether you are in St. Louis, Kansas City, or Springfield, the demand for drivers is high.
Getting licensed here is a two-step dance between the Department of Revenue (DOR) and the Missouri State Highway Patrol. This 2026 guide explains how it works.
1. The Missouri Two-Agency System
This confuses most new drivers.
- DOR (License Offices): This is where you pay fees, take your Written Exams, and pick up your actual license.
- Highway Patrol (Troop Headquarters): This is where you take your Road Skills Test. You cannot take the road test at a regular license office. You must schedule an appointment with the Highway Patrol CDL division.
2. Missouri CDL Fees (2026)
Missouri fees are among the lowest in the nation.
| Item | Cost | Valid For |
|---|---|---|
| Commercial Learner's Permit (CLP) | $7.50 | 1 Year (Non-renewable) |
| CDL License (3 Years) | $22.50 | 3 Years |
| CDL License (6 Years) | $45.00 | 6 Years |
| Written Test Fee | $2.50 | Per attempt |
3. Medical Certification (Form 5800)
You must submit a copy of your Medical Examiner’s Certificate to the DOR.
- Submission: You can email it to
dlmedcert@dor.mo.gov(Fastest method). - Status: If your status changes to “Not Certified” (expired medical), your CDL privileges are removed immediately.
