Step-by-Step Guide to Getting a CDL in Missouri
Step 1: Determine Your CDL Class and Endorsements
Determining the appropriate Commercial Driver License (CDL) class and necessary endorsements is a crucial first step toward operating commercial vehicles in Missouri. The Missouri Department of Revenue (DOR) provides official guidelines to assist you in making these determinations.
CDL Classes in Missouri
Class A CDL: Required for any combination of vehicles with a Gross Combination Weight Rating (GCWR) of 26,001 pounds or more, provided the Gross Vehicle Weight Rating (GVWR) of the vehicle(s) being towed exceeds 10,000 pounds. Holders of a Class A license may also operate vehicles within Class B and C, with appropriate endorsements.
Class B CDL: Pertains to any single vehicle with a GVWR of 26,001 pounds or more, or any such vehicle towing another vehicle not exceeding 10,000 pounds GVWR. Holders of a Class B license may also operate vehicles within Class C, with appropriate endorsements.
Class C CDL: Applies to any single vehicle or combination of vehicles that does not meet the definitions of Class A or Class B but is designed to transport 16 or more passengers, including the driver, or is placarded for hazardous materials.
CDL Endorsements in Missouri
Depending on your specific driving duties, you may need to obtain one or more endorsements to your CDL:
Hazardous Materials (H) Endorsement: Allows the transportation of hazardous materials requiring placarding. To obtain this endorsement, you must pass the Hazardous Materials knowledge test and complete a Transportation Security Administration (TSA) background check, including fingerprinting.
Tank Vehicle (N) Endorsement: Permits the operation of vehicles designed to transport liquids or gases in bulk tanks.
Passenger (P) Endorsement: Authorizes the operation of vehicles carrying passengers.
Double/Triple Trailers (T) Endorsement: Enables the operation of vehicles pulling double or triple trailers.
School Bus (S) Endorsement: Allows the operation of school buses for transporting pupils to and from school or related functions. Obtaining this endorsement requires passing both the Passenger (P) and School Bus (S) knowledge tests, holding a Commercial Learner’s Permit (CLP) with these endorsements for at least 14 days, and passing a skills test in a school bus of the same vehicle group.
It’s essential to determine the specific CDL class and endorsements applicable to your intended commercial driving activities before proceeding with the CDL application process. This ensures compliance with Missouri regulations and prepares you for the necessary tests and training.
For more detailed information, refer to the Missouri Department of Revenue’s Commercial Driver License Manual and the Missouri DOR website.
Step 2: Obtain a Commercial Learner's Permit (CLP):
Obtaining a Commercial Learner’s Permit (CLP) is a critical step toward securing a Commercial Driver License (CDL) in Missouri. Here’s a structured guide to help you navigate the process:
Eligibility Requirements:
Age: You must be at least 18 years old to apply for a CLP in Missouri.
Driver’s License: Possess a valid Missouri Class F (operator’s) license.
Medical Certification: Comply with CDL Medical Certification requirements by self-certifying your transportation status and, if applicable, submitting a valid Medical Examiner’s Certificate.
Application Process:
Prepare Required Documents:
Proof of Identity and Lawful Status: Provide one of the following:
Valid, unexpired U.S. passport or passport card
Certified U.S. birth certificate
Certificate of Naturalization
Certificate of Citizenship
Valid, unexpired Permanent Resident Card
Valid, unexpired foreign passport with an approved I-94 form
Social Security Number (SSN): Present your Social Security card or a W-2 form displaying your full SSN.
Proof of Missouri Residency: Submit two documents verifying your Missouri residential address, such as utility bills, lease agreements, or bank statements.
Study for Knowledge Tests:
- Review the Missouri Commercial Driver License Manual to prepare for the required knowledge tests.
Pass Required Knowledge Tests:
- Successfully complete written tests covering general commercial vehicle operation and any additional endorsements you seek (e.g., air brakes, passenger transport).
Apply for the CLP:
Visit a Missouri Department of Revenue (DOR) license office to submit your application.
Provide all required documents.
Pay the applicable CLP issuance fee.
Post-Application Steps:
CLP Validity: Your CLP is valid for 360 days and is non-renewable. If it expires, you must retake all required knowledge tests to obtain a new CLP.
Holding Period: You must hold the CLP for a minimum of 14 days before you are eligible to take the CDL skills test.
For comprehensive details and the most current information, refer to the Missouri Department of Revenue’s Commercial Driver License resources.
Step 3: Complete Entry-Level Driver Training (ELDT):
Completing Entry-Level Driver Training (ELDT) is a mandatory step for certain Commercial Driver License (CDL) applicants in Missouri, aligning with federal regulations established by the Federal Motor Carrier Safety Administration (FMCSA). Here’s what you need to know:
Who Needs to Complete ELDT?
As of February 7, 2022, ELDT is required for individuals who are:
Obtaining a Class A or Class B CDL for the first time
Upgrading an existing Class B CDL to a Class A CDL
Obtaining a Passenger (P), School Bus (S), or Hazardous Materials (H) endorsement for the first time
These requirements are not retroactive; individuals who held a CDL or the specified endorsements before this date are exempt from ELDT for those credentials.
ELDT Curriculum Components
The ELDT curriculum comprises two primary components:
Theory Instruction:
Covers essential topics such as basic operation, safe operating procedures, vehicle systems, and reporting malfunctions.
There are no minimum hours required; however, trainees must demonstrate proficiency by scoring at least 80% on assessments.
Behind-the-Wheel (BTW) Training:
Involves practical driving exercises conducted on a range and public roads.
While no specific number of hours is mandated, trainees must demonstrate proficiency in all required skills.
Detailed curriculum requirements are outlined in the FMCSA’s ELDT regulations.
Selecting an ELDT Provider
To comply with ELDT requirements, you must complete training through a provider registered with the FMCSA’s Training Provider Registry (TPR). Missouri mandates that driver education providers conducting commercial vehicle driver training be registered with the FMCSA through the TPR.
Verification of ELDT Completion
Upon completing the training, the provider will electronically submit your certification to the FMCSA. The Missouri Department of Revenue (DOR) will verify your ELDT completion through the federal Commercial Skills Test Information Management System before allowing you to proceed with the CDL skills test or the hazardous materials endorsement knowledge test.
Additional Considerations
No Minimum Training Hours: Missouri does not specify minimum training hours for ELDT; completion is based on demonstrated proficiency.
Exemptions: Individuals who held a valid CDL or the relevant endorsements before February 7, 2022, are exempt from ELDT requirements for those credentials.
For comprehensive information on ELDT requirements and to find registered training providers, consult the FMCSA’s Training Provider Registry and the Missouri Department of Revenue’s official resources.
Step 4: Practice with Your CLP:
After obtaining your Commercial Learner’s Permit (CLP) in Missouri, you are required to practice operating a commercial vehicle to prepare for the CDL skills test. This practice period ensures that you develop the necessary skills to safely operate a Commercial Motor Vehicle (CMV) under real-world conditions.
CLP Driving Rules in Missouri
While holding a CLP, you may only drive a commercial vehicle under the supervision of a qualified CDL holder. The supervising driver must:
- Be at least 21 years old.
- Hold a valid CDL for the same class and type of vehicle.
- Have the necessary endorsements for the vehicle and cargo.
- Remain seated in the front passenger seat at all times while you are driving.
What to Focus on During Practice
During your CLP period, you should focus on mastering the skills required for the CDL skills test, including:
- Performing a pre-trip vehicle inspection to check for safety and mechanical issues.
- Practicing basic vehicle control maneuvers, such as straight-line backing, offset backing, and parallel parking.
- Driving in real-world traffic conditions, including intersections, lane changes, merging onto highways, and following road signs.
Additional Practice Recommendations
- Practice in the same class and type of vehicle that you will use for the CDL skills test.
- If you take your test in a vehicle with automatic transmission or no air brakes, your CDL will have a restriction that may limit the types of vehicles you are legally allowed to drive.
CLP Holding Period
In Missouri, you must hold your CLP for at least 14 days before you are eligible to take the CDL skills test. The CLP is valid for 360 days and cannot be renewed. If your permit expires before you obtain your CDL, you must reapply and retake all required knowledge tests.
For official guidance and CDL training resources, refer to the Missouri Department of Revenue (DOR) or consult an FMCSA-approved training provider.
Step 5: Schedule and Pass the CDL Skills Test:
After holding your Commercial Learner’s Permit (CLP) for at least 14 days and completing any required Entry-Level Driver Training (ELDT), you can schedule your CDL skills test in Missouri. This test evaluates your ability to safely operate a commercial vehicle and is required to obtain your CDL.
How to Schedule Your CDL Skills Test
- The CDL skills test must be taken at a Missouri State Highway Patrol (MSHP) CDL Testing Site or an approved third-party testing location.
- Appointments for testing can be scheduled by contacting a Missouri CDL testing site directly.
- Ensure you have completed ELDT (if required) before scheduling your test.
What to Bring on Test Day
On the day of your CDL skills test, you must bring:
- Your valid Missouri driver’s license.
- Your Commercial Learner’s Permit (CLP).
- Your Medical Examiner’s Certificate (DOT medical card), if required.
- A commercial vehicle that matches the class of CDL you are testing for and is in safe operating condition.
CDL Skills Test Overview
The CDL skills test consists of three parts:
Pre-Trip Vehicle Inspection
- Demonstrate your ability to inspect the vehicle and identify any safety concerns.
- Explain what you are checking and why it is important.
Basic Vehicle Control Test
- Perform controlled maneuvers such as straight-line backing, offset backing, and parallel parking.
- Demonstrate control of the vehicle in a limited space.
On-Road Driving Test
- Drive in real traffic conditions while being evaluated on your ability to safely operate the vehicle.
- Navigate intersections, lane changes, highway driving, turns, and compliance with traffic laws.
Important Reminders
- If you take your CDL skills test in a vehicle with automatic transmission or no air brakes, your CDL will include a restriction limiting the types of vehicles you can operate.
- If you fail any section of the CDL skills test, you may have to reschedule and retake only the failed portion. However, policies may vary by testing site.
After Passing the Skills Test
Once you pass all sections of the CDL skills test, your test results will be submitted to the Missouri Department of Revenue (DOR), and you will become eligible to receive your Commercial Driver’s License (CDL).
For official CDL testing requirements and a list of approved testing sites, visit the Missouri State Highway Patrol (MSHP) CDL Testing Program or the Missouri Department of Revenue (DOR) website.
Step 6: Obtain Your CDL:
Complete the CDL Issuance Process
After successfully passing all three parts of the CDL skills test, your test results will be submitted electronically to the Missouri Department of Revenue (DOR). You must visit a Missouri DOR license office to complete the final steps and receive your Commercial Driver’s License (CDL).
What to Bring to the DOR Office
To obtain your CDL, you must provide:
- Your valid Missouri driver’s license.
- Your Commercial Learner’s Permit (CLP).
- Your Medical Examiner’s Certificate (DOT medical card), if required.
- Payment for CDL issuance fees (fees vary based on CDL class and endorsements).
CDL Issuance and Restrictions
Once your CDL is processed, the Missouri DOR will issue your license, which will include:
- CDL Class (A, B, or C).
- Endorsements (such as Hazmat, Tanker, or Passenger).
- Restrictions, if applicable (such as automatic transmission or no air brakes, based on the vehicle used for testing).
After Receiving Your CDL
CDL holders in Missouri are responsible for:
- Keeping their medical certification current to avoid CDL downgrade.
- Renewing their CDL before it expires (valid for up to 6 years).
- Updating their address or personal information with the DOR when necessary.
- Complying with state and federal regulations to maintain CDL eligibility.
Once issued, your CDL allows you to legally operate commercial vehicles according to your class and endorsements in Missouri and across the U.S. (if eligible for interstate driving). For official requirements and renewal policies, refer to the Missouri Department of Revenue (DOR) website or the Missouri CDL Manual.
Additional Considerations:
Medical Certification Requirements
CDL holders must maintain a valid Medical Examiner’s Certificate (DOT medical card) and provide it to the Missouri Department of Revenue (DOR). CDL holders must also complete a self-certification to declare whether they operate in interstate or intrastate commerce. Failure to maintain a valid medical certification may result in a CDL downgrade or suspension.
Hazardous Materials Endorsement (HME)
If you are applying for or renewing a Hazardous Materials (H) endorsement, you must:
- Pass the Hazmat knowledge test.
- Complete a TSA security threat assessment, which includes fingerprinting and a background check.
- Renew your background check every five years to maintain the endorsement.
Military Skills Test Waiver
Missouri offers a Military Skills Test Waiver Program for eligible service members with recent experience operating military vehicles. If approved, the waiver allows you to skip the CDL skills test, but you must still pass all required knowledge tests.
Driving Record Requirements
CDL holders are held to higher safety standards than regular drivers. Violations such as DUI, reckless driving, or using a commercial vehicle to commit a felony can result in CDL suspension, revocation, or disqualification. Even violations in a personal vehicle may affect CDL status.
CDL Renewal
Missouri CDLs are typically valid for six years. It is the CDL holder’s responsibility to renew their CDL on time and ensure that medical certification, endorsements, and background checks remain valid.
Vehicle Restrictions
If you take your CDL skills test in a vehicle with automatic transmission or without air brakes, corresponding restrictions will be placed on your CDL, limiting the types of vehicles you are allowed to operate.
Notification Requirements
CDL holders in Missouri must notify the DOR of:
- Address changes within 30 days.
- Medical certification updates to avoid CDL downgrade.
- Out-of-state traffic convictions or disqualifying offenses.
By following Missouri CDL regulations and staying compliant with state and federal requirements, CDL holders can maintain their driving privileges and legally operate commercial vehicles within Missouri and across the U.S.
