Idaho CDL Class A Practice Test 2025

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

Updated for December 2025, this Idaho General Knowledge practice test contains another 93 questions based on the official CDL (Commercial Driver’s License) manual. You can use this test to prepare for the General Knowledge portion of the ID CDL exam. These questions are multiple-choice, with three possible answers for each question. Only one of those answers is correct. If you’re not sure about the correct answer, you can use the hint provided for each question. Each hint points you to the correct answer without giving away the correct answer itself. This should allow you to make an informed decision about the correct answer, even if you don’t actually know it. There is no time limit for completing this practice test. Every time you answer a question, you’ll get immediate feedback with a detailed explanation, so you won’t need to wait until the end of the test to know the correct answers.

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!
