KY CDL Combination Vehicles Practice Test 4 2025

Perfect for first-time and renewal CDL/CLP applicants, and those adding endorsements.

The official Commercial Driver License Manual (Kentucky CDL Handbook 2025) is the primary study resource for most aspiring commercial drivers in Kentucky. This handbook discusses the various aspects of commercial driving theory in detail, including commercial driving regulations, emergency procedures, the licensing process, and the endorsements you can get on your CDL. You should read the contents of this manual multiple times during your learning phase. However, practice tests offer a systematic approach, which is much more effective than traditional study methods.

Our Kentucky CDL Combination Vehicles Practice Tests closely reflect the content and format of the official combination vehicles knowledge exam. The practice test that you’re about to take is the fourth in this series. All questions have multiple answer choices, but only one is correct. Several helpful features are included in the test settings menu, which you can access by clicking the three dots in the top-right corner of the page.

“Officer Frank” is your personal AI coach. He will be present during your training sessions, ready to provide assistance at your request. If you get stuck on a difficult question, you can ask “Officer Frank” for hints. He will provide you with information that nudges you in the right direction without revealing the correct answer. Additionally, this automated assistant can rephrase questions and provide detailed explanations.

With unlimited attempts and nonstop browser-based access, you can train anytime, anywhere in the world. Whether you prefer to train on your laptop, smartphone, or tablet, you can access this practice test on any compatible device. A stable internet connection is required at all times. If you must interrupt an active practice session, your progress will get automatically saved as long as you’re not using private browsing mode (such as Incognito mode in Google Chrome). When you access the practice test again, you will resume from the last question answered.

Start your training today and create a study routine you can follow consistently. You can use our Free Kentucky CDL Permit Practice Test to study general commercial driving theory. Pair it with the official commercial driver license manual to boost your learning potential. Within a few weeks, you’ll be ready to ace your theory exams on your first attempt.
