Getting a CDL in Missouri

3 min read

Obtaining a Commercial Driver License (CDL) in Missouri is essential for anyone who plans to operate large commercial vehicles such as tractor-trailers, buses, or tankers. The process is governed by both federal and state-level regulations to ensure that drivers are well-qualified and medically fit for the responsibilities of commercial driving.

Eligibility and Age Requirements

To qualify for a CDL in Missouri, applicants must:

Be at least 18 years old to drive intrastate (within Missouri only)
Be 21 or older to operate interstate or transport hazardous materials
Hold a valid Missouri driver’s license
Possess a clean driving record and be free from disqualifying offenses

You can review additional details on Missouri License Eligibility by Age to ensure you meet the minimum standards.

Steps to Obtain a Missouri CDL

1. Obtain a Commercial Learner’s Permit (CLP)

Before applying for a full CDL, you must first obtain a CLP:

Pass the CDL general knowledge written test
Submit proof of identity, residency, and legal presence
Provide your current driver’s license and Social Security Number
Pass a vision screening

You must hold the CLP for at least 14 days before taking the skills test. Training with a qualified instructor or trucking school during this period is highly recommended.

2. Schedule and Pass CDL Skills Tests

The skills test includes:

Pre-trip vehicle inspection
Basic control skills test
On-road driving test

Each segment is evaluated by a state-certified examiner. You’ll need to provide the appropriate class of vehicle for the test.

Get familiar with the Missouri Driver’s Skills Test Expectations to prepare for this crucial step.

CDL Classes and Endorsements

Missouri offers three CDL classes:

Class A – Combination vehicles (e.g., tractor-trailers)
Class B – Single vehicles over 26,000 pounds (e.g., buses, dump trucks)
Class C – Small vehicles transporting hazardous materials or more than 16 passengers

You may also need endorsements depending on the vehicle type or cargo:

H – Hazardous materials
N – Tank vehicles
P – Passenger transport
S – School bus
T – Double/triple trailers

For school bus drivers, see the Missouri School Bus CDL Endorsement Steps.

Medical Certification Requirements

All Missouri CDL applicants must provide a valid Medical Examiner’s Certificate (Form MCSA-5876) from a certified medical professional listed in the National Registry.

Missouri CDL holders must:

Self-certify the type of driving they perform (interstate or intrastate)
Keep their medical certification current

Review the Missouri CDL Medical Certificate Guide for documentation and submission details.

Renewing and Maintaining Your CDL

Missouri CDLs are typically valid for 3 to 6 years depending on your age and driving status. Renewal involves:

Providing current medical certification
Updating address or personal information, if applicable
Passing required vision screenings or retaking tests (for certain endorsements)
