DE CDL General Knowledge Practice Test 2 2025

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

This second DE General Knowledge practice test contains another set of 50 questions based on the official CDL manual. Just like the first practice test, this one is also designed to prepare you for the General Knowledge portion of your 2025 Commercial Driver’s License exam. There are several answer options, but only one of them is correct. Each question also includes a hint and an explanation. It is recommended that you check each question’s explanation to gain some further insight into the rule being tested. 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. Good luck and drive safely!

Best site For anything with wheels.
Driving-tests.org has been my go to site for all of my CDL test and I have passed the first time. I have used this site for my CDL class A permit, Tanker & Hazmat DMV exams. would not study anywhere else. I also used it to get my motorcycle endorsment.

I was the only one that passed the CDL out of 7 people.
I was the only one that passed the CDL A air brakes, general and combination test today out of 7 people. But I also passed the tanker and Double/triples test.I got 3 wrong. I credit this program to my success. I focused on the tests in the program. I loved the ability to flag 1 that I got right and could be grilled on it again plus having the ones I failed be put aside to do till I got then correct.

A much better way to learn.
Update: Took the exam. Passed the 1st time. 68 of 70 questions correct. This test prep works. I found absorbing the information in the CDL manual difficult. I could memorize the information but I wasn't learning how to apply it. It was like drinking from a fire hose. This format separates the signal from the noise. Now, I much better understand how to use and apply the information for both the CLP test and also as a professional driver. You still have to read the manual. This site helps you to learn what you're reading.

This site is awesome.
I passed my permit test today, flawlessly thanks to this site. I took my time and went through all of the many practice tests that they had and just like that, I have my cdl permit in hand. Thank you so much for this site.

A must to save time and money!
Studied for about 20 hours on my own for about 4 days for the class A CDL permit test. I failed General Knowledge and Air brakes on Monday. Was pretty flustered since I studied for a week. Bought this program on Monday night and took the test again Wednesday morning and passed easily. Was surprised how many of the same worded questions that are on driving-tests.org were on the official dmv test. Looking forward to using this for my endorsements. With Covid 19 and the long wait times. This course is a must if you can't afford or have the time to waste going to the dmv multiple days to retake tests.
