KY CDL General Knowledge Exam Simulator 2025

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

To get your Commercial Driver’s License (CDL) in Kentucky, you must first obtain a Commercial Learner’s Permit (CLP). This process involves passing a vision exam and the 50-question CDL General Knowledge (permit) test, submitting the required documents, and paying the license fees. You must also submit a current medical certificate unless you will be engaged only in so-called “excepted commerce.” To comply with FMCSA regulations, the KSP requires all aspiring commercial drivers to complete Entry-Level Driver Training (ELDT) from a registered provider before scheduling and taking the CDL skills test. The General Knowledge exam will test your knowledge of the various aspects of commercial driving described in the official Kentucky commercial driver license manual (Kentucky CDL Handbook 2025). To pass, you must score 80% or higher before the timer ends.

Understanding how to control your vehicle and handle emergencies will not only help you pass the exam but also keep you and other road users safe. Our Kentucky CDL General Knowledge Exam Simulator can help you become a safe and responsible commercial driver. As you begin your learning phase, you should use this tool on a daily basis. Keep track of your scores and see them naturally improve over time. All 50 questions have multiple answer choices, but only one is correct. If you make too many mistakes, the test ends immediately, and you’ll have to start over.

Since you benefit from unlimited attempts, you can take the test as often as you need. However, we recommend checking your Challenge Bank™ occasionally, as it contains detailed explanations and useful feedback that can help you learn from your mistakes. With the voiceover feature, you can study even in distracting environments. Once activated, an artificial voice will read the questions and answer choices aloud, making it easier for you to pay attention and focus on the simulator.

The journey to obtaining a CDL may seem long at first, but any goal is within your reach. With preparation and determination, you can master commercial driving theory within a few weeks and ace the official CDL General Knowledge exam on your first attempt.

Came across driving-tests.
I came across driving-tests.org, and their process and the way they had you do the studying and the tests made the world of difference for, like, both feeling confident and then, you know, the material, but also, like, being able to discern in the question, like, what they're actually after, and finding the best possible answer. Coming to the test today after using this versus the first two times, I felt way more confident, and I think I only missed, like, three questions or four questions on all three tests that I had to take today. So I highly recommend this anyone trying to get their CDL.

Everything went fine the study guide was right on and i took test and past just like that!
A
Excellent.
Well, wasn't the first time I used driving-tests.org to prepare to write driving test exam. I used in KY to take my CDL and HME written exams and passed both excellent. This was the reason I returned driving-tests.org to prepare for GA HME endorsement. I followed driving-tests.org recommendations and went through all practice tests and was 100% ready. The written exam on 8/31/2022 was a breeze. It took me less than 10 minutes to finish. I could have obtained a 100% score but due to my own carelessness / mind laziness / arrogance, I got one question wrong. I will always recommend driving-tests.org to people. Thank you driving-tests.org!

I'm in the process of getting Hazmat….
I'm in the process of getting Hazmat and Motorcycle endorsements on my license. I obviously had many choices but I felt like this was my best option. I'm using the site and website, both seem to be slightly different as to what they offer. Look carefully and if you're going to choose just one, I would probably go with website, as it has a course (video) that can be completed and results sent to DMV. I Really Appreciate That FEATURE!
JD
Very thorough.
Well written tests with hints and answers which bring an understanding that sinks in so that you remember. Very thorough videos that are packed with all the info you can stand. A learning path is laid out for you so that as you progress you can sense a mastery of the CDL profession.

The #1 Driving Test Website In The Country!
Driving-tests.org is the best driving test website in the country why? Because everything on this website is explained in full detail and I love the fact that everything is in order. Unlike the very confusing drivers manuals in each state with driving-tests.org everything is in order again especially with the membership. The air brakes test, the General Knowledge Test, the combination vehicle test, and Etc is in order. The driver's manual is very confusing to have all the answers scattered out through the entire book which is ridiculous and it makes it harder for the person that studying any drivers test to pass and the DMV knows that.
MR
Awesome App.
I studied the manual and felt prepared to pass the CDL exam. I took it on 1/10/19 and failed it twice. I was discouraged but started to research online for test applications. I ran into The Driving Test app and gave it a chance. I studied the test examples for over 9 hours. Went to DMV late afternoon on 1/11/19 to retake the test and passed it on the first try. the site is simply amazing!
