Missouri CDL Practice Test 2026: DOR Fees & Highway Patrol Testing
Don't just read the guide. Test yourself with the actual questions likely to appear on your CDL test.
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.
4. MO Practice Questions
Consistent with federal law, Missouri sets the DUI limit for CDL holders at 0.04%, which is half the limit for regular drivers.
