Free Kansas CDL Permit Practice Test: General Knowledge 2025

Welcome to our free Kansas CDL permit practice test! You’ve probably started studying the official Kansas Commercial Driver’s License Manual (Kansas CDL Handbook 2025) to prepare for the official CDL General Knowledge test. By taking this practice test, you’ll absorb the relevant material more easily and become used to taking tests on it. The practice test is based on the official state CDL Study Guide, just like the official knowledge test. It’s up to date as of March, 2025 and has 50 multiple-choice questions. The questions on this practice test will assess your understanding of such topics as cargo management, emergency preparedness, vehicle components, pre-trip inspections, and safe driving techniques. Unlike the official knowledge test, however, this practice test comes with an automated assistant that can help you out with a hint and an explanation of the correct answer for each question.

Passing the official knowledge test is one of the requirements you must meet to become eligible for a Commercial Learner’s Permit (CLP). Holding a CLP will legally enable you to practice commercial driving under the supervision of someone who already holds a Commercial Driver’s License (CDL). To obtain a CDL yourself, you must become good enough at commercial driving that you can pass the official skills test. The skills test will evaluate you on performing basic vehicle maneuvers, a pre-trip inspection, and a road test.

There are three classes of CDLs: Class A is typically for large combination vehicles, such as semi-trucks and tractor-trailers. Class B is typically for single-unit vehicles, such as large buses and straight trucks, including box trucks and most dump trucks. Class C is typically for smaller commercial vehicles that transport hazardous materials or at least 16 occupants (including the driver), such as shuttle buses and small trucks carrying hazardous materials. Decide which class you want, based on the types of vehicles you expect to be driving commercially in your career.

Once you obtain a CDL and all the endorsements you need, you can really begin a career as a commercial driver. Most of the land of Kansas is given over to agriculture (especially wheat), which needs truckers to transport its products, of course. Another major economic sector is aerospace; several large firms manufacture aircraft here. Garmin is also located here. High-tech companies, such as those involved in aerospace, also need truckers to deliver materials and equipment to them.

Major commercial routes in Kansas include Interstate 35, which connects Wichita, El Dorado, and Kansas City; Interstate 70, which passes through several Kansas cities including Topeka, Lawrence, and Kansas City; and U.S. Route 69, which passes through eastern Kansas.
