Delaware CDL Class A Practice Test 2025

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

In Delaware, the official CDL general knowledge exam includes 50 multiple-choice questions based on the official State of Delaware Commercial Driver License Manual (Delaware CDL Handbook 2025). You must score 80% or higher to pass, leaving little room for error. This manual is your main study resource and covers a wide range of topics, including pre-trip inspections, safe driving practices, space management, and cargo handling. The Department of Motor Vehicles (DMV) advises aspiring drivers to read the contents of this manual multiple times during their learning phase.

To ensure you’ll pass the official written knowledge test on your first attempt, you should incorporate our Delaware CDL Class A Practice Test into your study routine. Learn what it takes to become a safe and responsible commercial driver and train with this practice test multiple times a day. You get unlimited attempts and nonstop access to practice as often as your schedule allows.

All missed questions will be automatically added to your personal Challenge Bank™, which includes detailed explanations that help you understand your mistakes. Once you answer those questions correctly, they will be removed from your Challenge Bank. Visit this section occasionally to identify areas that need improvement and understand the reasoning behind the correct answers.

To help you study effectively, we have included a voice-over feature. You can activate it from the test settings menu located in the top-right corner of the page. This function uses an artificial voice to read each question and answer choice aloud, making it easier for you to focus. Use it if you’re studying in busy or distracting environments or if you retain information better by listening.

With a user-friendly interface and several other features, our Delaware CDL Class A Practice Test is the ideal tool to help you master commercial driving theory. Practice daily, track your progress, and gain the confidence you need to pass the official written knowledge test on your first attempt. Your career as a commercial driver in Delaware begins with a learning journey, and we’re here to support you along the way.

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.

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.
