ID CDL General Knowledge Exam Simulator 2025

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

Have you always dreamed of becoming a truck driver? Perhaps you’re more interested in transporting passengers on a bus. Becoming a commercial driver in Idaho takes time and effort, but turning your dream into reality is achievable with preparation and dedication. Take the first step and begin your learning phase, where you’ll spend several weeks studying the various aspects of commercial driving theory. The DMV publishes the official Idaho commercial driver’s license manual (Idaho CDL Handbook 2025). All 50 questions on the official CDL permit test are based on this resource, which you should read at least once.

Our Idaho CDL General Knowledge Exam Simulator can be a game changer for students who struggle with test anxiety. As exam day approaches, it is completely normal to feel nervous and overwhelmed. Replace this anxiety with confidence by simulating the official exam experience and practicing regularly. This intuitive tool has been designed to closely reflect the content and format of the official exam. The simulator won’t give you hints or other help to answer the questions. However, we have omitted any timer for your convenience. Take as long as you need to answer all 50 multiple-choice questions, and only select an answer when you’re confident in your choice. To pass, you must score at least 80%. If you make too many mistakes, the test ends immediately. Since you get unlimited attempts, you can start a new session right away. However, we recommend checking your Challenge Bank first, as it contains detailed explanations for all the questions you got wrong before.

To simulate the official testing experience as accurately as possible, you should refrain from using other resources while practicing on our simulator. You will not receive any help at the DMV office when you take the official exam, where every mistake will have a significant impact on your chances of passing. While you are still in your learning phase, you can use our other practice tests to strengthen your knowledge and master this subject through repetition. The most determined students always use the most efficient tools available, so you should adopt a smarter approach and use our simulator as the final step before you take the official exam.

Couldn't be happier!
I was a little sceptical when I first learned of this website while searching for some information regarding CDL testing on Google. I downloaded a current PDF drivers manual from the DMV website, and read the information I needed in its entirery. I felt fairly confident by this point already, but after going through all the practice tests and flash cards on the site I could answer the questions without even thinking. I was sure once I got to the DMV to take the actual tests that the questions were going to be flipped around and worded completely different but to my surprise and relief they weren't! I passed the three tests that I had studied for with the help of driving-tests.org flawlessly. I honestly couldn't be happier with my results. Incase you haven't realized by this point, I would definitely recommend this website for your CDL test taking needs. C.

I came into CDL/CLP realm with NO prior experience of the material. Tried it twice, back to back, failed both times. I got this, spent a whole day doing the practice tests, marathons, ect. Took my tested today, passed with a 95%. 10/10 would recommend to anyone! Well if you really invest your time into the material! Thank you for this!
