Kansas CDL Endorsements and Requirements

4 min read

Operating a commercial motor vehicle (CMV) in Kansas requires more than just a standard driver’s license. The Kansas Commercial Driver’s License (CDL) comes with specific endorsements and regulatory requirements designed to ensure safety and compliance with federal and state laws.

CDL Classes in Kansas

Kansas issues CDLs in three classes based on vehicle weight and configuration:

  • Class A: Required to operate any combination of vehicles with a Gross Combination Weight Rating (GCWR) of 26,001 pounds or more, provided the vehicle being towed is over 10,000 pounds.
  • Class B: For any single vehicle with a GVWR of 26,001 pounds or more, or towing a vehicle not exceeding 10,000 pounds.
  • Class C: Covers vehicles that do not meet the criteria for Class A or B but are designed to transport 16 or more passengers (including the driver) or hazardous materials.

Mandatory CDL Requirements

To qualify for a Kansas CDL, applicants must:

  • Be at least 18 years old for intrastate driving or 21 for interstate commerce and hazardous materials.
  • Possess a valid Kansas non-commercial driver's license.
  • Provide proof of lawful presence in the U.S.
  • Submit a current Department of Transportation (DOT) medical certificate.
  • Pass a written knowledge test and a skills (road) test for the appropriate vehicle class.

Each endorsement requires additional written tests and, in some cases, a driving test.

Kansas CDL Knowledge and Skills Tests

All applicants must pass the appropriate knowledge test for their CDL class and any endorsements. After passing the written exams, applicants must schedule and pass a skills test which includes:

  • Pre-trip vehicle inspection
  • Basic control skills test
  • Road test

Training is strongly recommended, and the state provides access to various Kansas CDL Training Programs and Schools.

Intrastate vs. Interstate Requirements

  • Intrastate drivers (within Kansas only) must be at least 18 years old.
  • Interstate drivers (crossing state lines or transporting certain types of cargo) must be at least 21 and meet Federal Motor Carrier Safety Administration (FMCSA) standards.

Self-Certification and Medical Requirements

All CDL holders must self-certify to one of four categories regarding the type of driving they perform and must maintain a valid medical certificate if required. Failure to maintain current medical certification can result in CDL disqualification.

Hazardous Materials Endorsement (H Endorsement)

The Hazmat endorsement involves additional layers of security:

  • Passing the Hazmat knowledge test
  • Completing a TSA security threat assessment
  • Fingerprinting and background checks

Refer to the Transportation Security Administration (TSA) for step-by-step application instructions.

Renewal and Downgrades

CDLs must be renewed every 4 years in Kansas. Renewal requires passing vision tests and submitting a current DOT medical certificate. Read more about Renewing Your Kansas CDL for timelines and documentation.

Failure to meet ongoing qualifications (like medical updates or address changes) can result in license downgrades or suspension. Be sure to promptly Update Your Address with the Kansas DMV if you move.
