You’ll need a Class A Commercial Driver’s License (CDL) to operate combination vehicles in Kansas. This license can be obtained by passing several theory and skills exams. Your knowledge of commercial driving theory will be evaluated through 50 multiple-choice questions on the official general knowledge exam. A minimum score of 80% is required to pass, leaving little room for error. Our Free Kansas CDL Permit Practice Test can help you prepare in advance. Train with this intuitive tool for several weeks and watch your knowledge and confidence gradually improve.
The second theory exam will evaluate your understanding of coupling mechanics, air braking systems in combination vehicles, pre-trip inspections specific to combination vehicles, and emergency situations. The official combination vehicles knowledge test consists of 20 questions based on Section 6 (Combination Vehicles) of the official Kansas Commercial Driver’s License Manual (Kansas CDL Handbook 2025). Our Free Kansas CDL Combination Practice Test is the solution to your study needs.
