Driving tractor-trailers or other combination vehicles in Kansas requires earning a Class A Commercial Driver’s License (CDL). To qualify, you must pass the Combination Vehicles Knowledge Test and meet other state and federal requirements before taking your CDL skills exam. According to the Kansas DMV, you cannot take the CDL skills test until you complete Entry-Level Driver Training (ELDT) with an FMCSA-approved training provider listed on the Training Provider Registry and pass the CDL General Knowledge Test to obtain a Commercial Learner’s Permit (CLP). Once you’ve held your CLP for a minimum of 14 days, you can take the Skills Test.
The Kansas Combination Vehicles Knowledge Test requires a minimum passing score of 80% and consists of 20 multiple-choice questions. Topics include safe operation of combination vehicles, air-brake systems in tractor-trailers, proper coupling and uncoupling procedures, preventing skids and jackknives, and inspection requirements. If you fail the test, you must wait one business day and pay a retest fee for each additional attempt. Our experts have put together a series of valuable practice tests to help ensure you pass the official test on your first attempt!
Our Kansas CDL Combination Practice Tests are based on the format and content of the official exam, offering feedback in real time (versus all at once at the end of the assessment!). The practice tests are based on the latest Kansas CDL Manual (Kansas CDL Handbook 2025).

Kansas’s 141,000 miles of highways are made up primarily of I-70, I-35, and U.S. Highway 54. Major Kansas employers hiring Class A drivers to haul freight along these roads include Dillons Supply Chain, FedEx Freight, Koch Industries, Tyson Foods, UPS, and Walmart. Tons of opportunities await you once you’re licensed!
Most combination tractors use air brakes, so you’ll also need to pass the Air Brakes Knowledge Test to avoid a restriction on your CDL. You can prepare with our Kansas Air Brakes Practice Test. Consider studying for optional endorsements as well, such as Tanker (N), Hazardous Materials (H), and Doubles/Triples (T), to further expand your career potential.
