Based on official Wisconsin exam questions

Free Wisconsin CDL Permit Practice Test: General Knowledge 2025

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

In the great state of Wisconsin, the most important economic sectors are agriculture (including butter, milk, and cheese), manufacturing (including paper products and processed foods), and tourism, all of which have created a demand for commercial drivers. Major commercial routes include Interstates 43, 90, and 94; U.S. Route 41; and State Highway 29. On I-43 and I-94, traffic congestion near major cities is a frequent problem. Furthermore, winter driving conditions on Wisconsin’s roads can be difficult and treacherous; heavy snowfall and icy road surfaces can make some minor roads nearly impassible.

You have a number of requirements you must meet before you may obtain a Commercial Driver’s License (CDL), which will allow you to legally drive commercially. Most importantly, you must become proficient at commercial driving to pass the official skills test. To practice commercial driving (under supervision), you must obtain a Commercial Learner’s Permit (CLP). The requirements for a CLP you must meet include submitting to a physical examination and passing the official General Knowledge test on commercial driving theory.

You have likely been advised to study the official Wisconsin Commercial Driver’s License Manual (Wisconsin CDL Handbook 2025). The manual does contain all the information on which you’ll be tested. However, many aspiring drivers have found it difficult to absorb and retain much of the information in the manual. If you’re having the same problem, we can help you with some additional study tools.

This free Wisconsin CDL permit practice test you’re about to take will evaluate your understanding of certain commercial driving topics. It’s based on the official CDL manual, just like the official knowledge test. And it’s up to date as of October, 2025. The 50 multiple-choice questions on this practice test will assess your understanding of such topics as driving maneuvers, cargo management, emergency preparedness, and pre-trip inspections. Unlike the official test, however, this practice test comes with an automated assistant that can give you various kinds of help, including hints to gently guide you to the correct answer and an explanation of the correct answer. Plus, there’s no time limit. Take all the time you need to learn the material. If you’re not sure how to answer a question, put the practice test aside momentarily while you try to look up the correct answer in the CDL manual. You’ll learn far more by researching the correct answer to the question than by guessing it.

I did not even look at the DMV manual.
I followed the program and retook my incorrect questions. I got 100% on my haz mat test at the DMV. Amazing prep program! I would totally recommend this to anyone!

Got my cdl and tanker endorsement last year and wanted to.
I got my cdl and tanker endorsement last year and wanted to get my hazmat endorsement also but the school I went to charged 500 dollars for a day and a half for hazmat training I looked for other alternatives and found this website 100 dollars for 30 days and it definitely paid off it less than 15 mins if that to pass the test and get my hazmat endorsement I highly recommend this program.
N
I took hazmat and tanker finished both….
I took hazmat and tanker finished both in about 5 minutes with 100% on both. every question on both tests were in the practice test!
CW
Simple to navigate and understand.
All the questions and answers to not only the general questions but endorsements to pass for your CDL license. This course actually saved me hundreds of dollars which was I was going to be charged for, for the 1st week of CDL training.

Tested for CDL hazmat endorsement.
I signed up to renew my CDL hazmat endorsement. Today, I've taken my test, and passed the 1st time with flying colors! Thank you very much for the material! I couldn't have done it without this and all of the work you put into this program!
SI
Love this testing platform.
I studied for 2 days and passed my cdl test with flying colors! Trustpilot even said I only had a 50% chance of passing my test. The tests helped a lot! I would recommend to anyone going it alone in this process.
MH
Passed on the first try.
I needed to upgrade my class A CDL to include a Tanker/Hazmat endorsement. I looked at a couple of other companies, but this was the most reasonable. The website was user friendly and I passed on my first try! I also was able to ask a couple of questions online and got responses and my questions answered. It was a good overall experience.
R
Thanks to this site.
When I first went to DMV to take My CDL General knowledge I failed miserably. Didn’t think Id ever had a shot at passsing it. Luckily I came across this website via a google search and signed up within a couple of days I built the confidence to go retake the test and I only got 1 wrong. Trust the process of studying for the test with this website and you’ll have no problem passsing. Well worth the $$$.
RB
Very Very UP TO Date AND Accurate.
Same questions on the exam! Studied 3 days before the exam and passed all 3 CDL tests in under 10 min! This is hands down the best website to study from and definitely worth the price!

The best product out there for CDL students.
I've used Driving-Tests a couple times now when studying for CDL GK written test and also for getting endorsements. Bottom line it's the best product I've seen, through and through. And I've sampled an array of different study guides, practice tests, cliffnotes and different apps to get prepared for CDL written testing at the DMV. None come close. Driving-Tests is just so comprehensive. The have videos, ELDT, tons of practice questions, summaries, AI chat in case you get stuck on a topic or question, challenge bank feature to hone in on questions you got wrong, the algorithm explains why your answer was right/wrong, and perhaps best of all, their customer service team is absolutely a pleasure to work with. Just drop them an email and they'll be back at you in minutes. If only the DMV staff were this helpful, attentive, and competent. I have had nothing but success using Driving-Tests to prepare for written testing at the DMV. It's so simple. Read the CDL manual for your state. Take the Driving-Tests practice tests. Watch their ELDT training. Feel of confidence as you crush the written test. It's not cheap, but it's

These practice tests prepared me and….
These practice tests prepared me and gave me the confidance to pass the CDL general knowledge and air brakes tests. If i could give them more than 5 stars, i would!
CS
A product that comes from heaven..
So far I don't have any complaint about this product. I am training for a CDL license and I find the knowledge in this product to be Very useful. I read the CDL book for my state and it was hard for me to remember everything and to grasp some concepts. But with that product, for every question, they not only provide the right answer, but they also mention in what section of the CDL book (for your respective state) that the answer is coming from. This product also have simulations for all CDL exams, be it the "General Knowlodge" test or any other "CDL endorsment" that you may want to pursue. This product keeps track of your progress for the different tests. It also gives you, based of well (or how poorly) you perform in a test, the percentage of your readiness for that test. To me that feature in this product is very valuable because, with CDL licensing, I am in a new territory. It is very helpful to me to know my level of readiness as I getting prepared to take the CDL exam.

10/10 recommend.
This has really helped me alot. About 6 months ago I used it to study for my CDL exams just a few days before I took them and I passed on my first try. They are up to date with everything needed to pass exams. I used it again last week for my endorsements and i passed. They are really helpful. 10/10 recommend.
AF
Only studied for 3 days.
Studied three days and passed my GK and Hazmat on the first try. Follow their action plan / tips and you will pass. Highly recommend! Update. couple days later I also passed my tanker, air breaks, doubles & triples, and combination vehicle test. Got my permit with endorsements.
