ExploreAbout this exam
The Kansas CDL Combination credential is the Class A commercial driving qualification for drivers who operate a tractor-trailer or other combination vehicle with a gross combination weight rating of 26,001 pounds or more, as set by the Kansas Department of Revenue Division of Vehicles. It is aimed at people entering trucking, farm and heavy-haul operations, and at drivers adding a combination rating to an existing Kansas CDL. To earn it you pass a knowledge test built on general CDL knowledge and combination-vehicle material - coupling and uncoupling, inspection, air brakes, weight distribution, turning and braking behavior, and safe following distances - and then a skills (road) test in a representative combination vehicle. Preparation means studying the Kansas Commercial Driver's License Handbook, drilling combination-vehicle coupling and inspection procedures until they are automatic, and practicing the pre-trip inspection aloud. Kansas also requires medical certification through the National Registry of Certified Medical Examiners; since 6/2/2025 the state no longer manually enters medical examiner's certificates, so confirm your examiner submits electronically before test day.

What you'll study
About Kansas CDL Combination preparation
What tests make up the Kansas CDL Combination exam?
Two parts: a multiple-choice knowledge test covering general CDL knowledge plus combination-vehicle material, and a skills (road) test in a combination vehicle representative of the class you want. You must pass the knowledge test before scheduling skills testing, and the skills portion includes a pre-trip inspection and basic control maneuvers.
How long does the skills test take?
Kansas states a CMV skills test can take from one hour to one and one half hours depending on conditions. Because schedules vary with business conditions, call the CDL testing facility in advance to confirm availability, and expect the examiner to need the full window.
Do I need an appointment for the skills test?
Yes. Kansas says scheduling is necessary to ensure a CDL examiner is available to administer the test. Contact a CDL testing office directly rather than showing up, and ask about current testing schedules, since they vary by location and business conditions.
What weight requires a Kansas CDL?
A CDL is required for any single vehicle with a gross vehicle weight of 26,001 pounds or more, or a combination vehicle with a gross combination weight rating of 26,001 pounds or more. The combination rating applies to tractor-trailers and similar rigs at or above that threshold.
How hard is the combination knowledge test?
It is not trick-based, but it is detail-heavy. Coupling and uncoupling order, glad-hand and electrical connection checks, trailer brake tests, and off-tracking in turns are common stumbling points. Memorize the sequences in the Kansas CDL Handbook and you will handle most items confidently.
What is the most common reason people fail the skills test?
Incomplete or out-of-order pre-trip inspections, missed trailer air-line and electrical connections, and poor backing or offset maneuvers. Kansas examiners also monitor tests for quality control, so narrate your inspection clearly and do not skip steps to save time.
What should I study first?
Start with general CDL knowledge, then move to combination-vehicle chapters: inspection, coupling and uncoupling, air brakes, and safe driving. Practice the pre-trip inspection out loud on a real rig before scheduling, because it is the highest-volume section of the skills test.
Is there anything special about medical certification in Kansas?
Yes. Effective 6/2/2025, Kansas no longer manually enters your medical examiner's certificate; information must come electronically from the National Registry of Certified Medical Examiners. Confirm your examiner is registered and submits electronically, or your CDL issuance may be delayed.
Can I retake the test if I fail?
Kansas publishes retake rules through its CDL FAQ and testing offices rather than in a single stated figure, so confirm current waiting periods and fees with the Division of Vehicles or your testing facility before rescheduling. Plan your first attempt carefully to avoid the delay.
