Missouri CDL Requirements

Missouri CDL Fees and Costs

The Missouri Department of Revenue (DOR) estimates that most first-time CDL applicants with a valid CLP pay approximately $83 total. This breaks down into several components:

Fees may differ depending on the license term length, additional knowledge tests required, or credited fees from previous transactions. For exact costs specific to your situation, contact a Missouri license office directly.

Age Requirements

Missouri follows federal CDL age requirements:

All CDL applicants must have a valid Missouri operator's (Class D) license before applying for a CDL.

Skills Test (Road Test) Requirements

After holding your CLP for at least 14 days, you may schedule the CDL skills test. Missouri uses the updated FMCSA CDL Skills Test Modernization format, effective December 4, 2023.

Skills Test Components

1. Vehicle Inspection (Pre-trip): Demonstrate knowledge of checking all safety-related vehicle components
2. Basic Control Skills: Backing maneuvers and vehicle control exercises (updated under Skills Test Modernization)
3. On-road Driving Test: Operating in traffic, making turns, navigating intersections, and performing lane changes

Testing Providers

Skills tests are conducted by:

• Missouri State Highway Patrol (MSHP): State-administered testing
• Certified Third-Party Testers: Approved driving schools and companies

Important: You must take the skills test in a representative vehicle for your desired class and endorsements. After passing, bring the completed examiner forms to a Missouri license office to finalize your CDL issuance.

Medical Certification Requirements

Missouri enforces federal CDL medical certification rules. Most commercial drivers must obtain a DOT Medical Examiner's Certificate before CLP or CDL issuance.

Who Needs Medical Certification

• Drivers operating in non-excepted interstate commerce
• Drivers operating in non-excepted intrastate commerce

Medical Exam Process

• Exam must be performed by a certified medical examiner listed on the National Registry of Certified Medical Examiners
• You must self-certify your medical status category when applying
• Drivers with physical impairments may need a variance (Skill Performance Evaluation) from MoDOT or FMCSA

Entry-Level Driver Training (ELDT)

Missouri follows federal ELDT requirements. Unless an applicable exemption applies, new CDL applicants must complete an FMCSA-approved ELDT program.

ELDT is Required For:

• First-time Class A CDL
• First-time Class B CDL
• Upgrading from Class B to Class A
• First-time Passenger (P), School Bus (S), or Hazardous Materials (H) endorsements

Training completion is recorded in FMCSA's Training Provider Registry (TPR) and must be verified electronically before skills or HazMat knowledge tests can be scheduled.

Testing Locations and Scheduling

Knowledge Testing and CLP/CDL Issuance

• Conducted at Missouri contract license offices (DOR license offices)
• Bring required identity, lawful status, Social Security, and Missouri residency documents
• Include medical certification if required

Skills Testing

• Schedule through MSHP CDL test sites or approved third-party testers

Active-duty or recently separated military personnel may waive the CDL skills test if they:

School Bus Endorsement

Missouri applies additional evaluation criteria for school bus endorsement applicants per §302.272 RSMo and 12 CSR 10-24.160, beyond standard federal requirements.

Skills Test Modernization

Missouri fully adopted the new FMCSA skills test format effective December 4, 2023, with updated CDL Manual sections to reflect these changes.

Reciprocity and Interstate Recognition

Missouri participates in the federal CDL program, which provides:

• Nationwide recognition of valid CDLs issued by other states
• Interstate information sharing for safety and compliance
• One CDL per driver rule (issued by state of domicile)

Out-of-state CDL holders who establish Missouri residency must transfer their CDL to Missouri as their new state of domicile.
