Missouri CDL Resources

Here are more resources related to getting your CDL in Missouri:

CDL Permit Testing in Missouri

To get a CDL Learner’s Permit, which you need to have in order to enter attend a trucking school and to undergo CDL testing, you will need to independently study for and pass permit testing (in addition to meeting all eligibility and fitness requirements). To study, you will utilize the Missouri Commercial Driver License Manual, and Missouri CDL practice tests that you can find online or in books. The CDL Manual will cover everything you need to know for testing, but it’s necessary to learn which parts will be emphasized the most and that you need to memorize in order to pass. You might need to use other sources to aid in your understanding of the manual’s contents.

The exam will only be a written test, not a driving test, as you need to obtain the learner’s permit before you can operate a commercial vehicle and be tested on driving skills. In trucking school, the permit will allow you to complete all of the in-vehicle instruction needed to go through the full CDL test. The cost of the Commercial Learner’s Permit for Class A, B, and C is $7.50 (not including other costs for items leading up to obtaining the CLP).

Commercial Learner’s Permit Eligibility Requirements

In the state of Missouri, you must be at least 21 years of age to be eligible to drive commercially intrastate (across state lines) or to haul hazardous materials. Note that a Hazmat endorsement is not possible for the Commercial Learner’s Permit in Missouri. You must be at least 18 to obtain a CDL of any kind.

You must also meet driving record eligibility requirements. Disqualification is possible for the same things as for an active CDL-holder. These include alcohol use, drug use, and serious traffic violations that occurred while you were operating any type of vehicle and in any capacity. You must have a valid regular Missouri driver’s license.

You must also meet medical and physical requirements, and have already been examined by an FMCSA (Federal Motor Carrier Safety Administration) certified medical examiner and obtained a Medical Examiner’s Card. Costs for the exam vary, but it will usually be less than $150 and greater than $35.

Locate a certified medical examiner in your area

After you have obtained your medical card, to begin the process of getting your Commercial Learner’s Permit (CLP), you must contact and visit a Missouri Department of Revenue office.

Find your Department of Revenue office location

You will need to bring the following to the Department of Revenue office. Contact your local office for specific details on any other documents you may need:

  • Missouri regular driver’s license (note that it is not permitted to transfer a Commercial Learner’s Permit from another state to Missouri)
  • Proof of Mississippi residency
  • Proof of a valid Social Security Number
  • Proof of United States citizenship, lawful permanent residency or immigration documents--these can include a U.S. birth certificate; U.S. passport; U.S. certificate of citizenship, naturalization, or birth abroad; or a photocopy of a U.S. birth certificate with a U.S. Military Identification Card or U.S. Military Discharge papers

In addition to your medical examination, the Department of Revenue office will also likely perform its own health screening questionnaire, and will administer a vision test, similar to the process for getting a regular driver’s license. The vision requirement for driver’s licenses is 20/40 acuity. Contact your Department of Revenue office for more information on vision and physical requirements.

Commercial Learner’s Permit Knowledge Tests

You won’t know exactly what is on the Missouri learner’s permit test until you are taking it, so it’s necessary to thoroughly study the CDL Manual.

Missouri Commercial Driver’s License Manual

Common topics that are likely to be on the permit tests include, but are not limited to the following, specifically as they relate to commercial vehicles:

  • Questions specific to your intended CDL Class (A, B, or C)
  • Questions specific to your intended CDL Endorsement (Passenger, Tank, or School Bus); note that for the learner’s permit in Missouri, Hazmat, Hazmat/Tank, and Double and Triple endorsements are not possible
  • Vehicle inspection
  • Vehicle and speed control
  • Shifting gears
  • How to see or anticipate hazards
  • Signaling, communication, and spatial proximity with other drivers
  • Railroad crossings
  • Hazards of distracted and drunk driving
  • Staying alert and physically fit to drive
  • Driving at night
  • Driving in various weather conditions
  • Emergencies on the road and accident procedures
  • Braking
  • Skid control
  • Transporting cargo safely
  • Air brakes

After you have completed the entire CLP process, you must wait 14 days to be eligible to undergo full CDL testing. An education program in the interim is necessary to be able to learn and practice the skills needed for that testing, as well as in-depth training on governmental regulations and being successful in a career and lifestyle in trucking.
