Kansas CDL Combination case studies
Kansas CDL Combination · Put your knowledge to work in context.
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. The Kansas CDL Combination case studies are 5 cases and about 2,395 words.
