    When you take and pass the CDL test and you have your license a whole new world of career options will open up to you. Suddenly you will find that it is much easier to get a job and you can demand a higher salary or hourly wage. Of course, you can’t just walk down to your local motor vehicle department; you actually have to take the CDL general knowledge test. For many, this is very intimidating and they allow for the test to stand between them and a career that they love.

    Understand the Test

    CDL general knowledge test is one of several parts of the test that you made need to take for licensing for any job that you aspire to have. For instance, if you want to drive a class A, B or C vehicle you need to take both the general knowledge and the transporting cargo test parts. If there is a chance that you will be driving a vehicle with air brakes, you also need to take the air brakes section of the test. If you do not take this part of the test you may limit your ability to drive many different types of vehicles.

    If you would like to drive combination vehicles you will also want to consider taking the combination vehicle portion of the test. As you can see, you really need to plan ahead so you know what to expect. Of course, you should start with the general knowledge area and expand out from there. While it can be overwhelming to think of how many areas of knowledge you need to ascertain, starting with the general knowledge test will give you the confidence you need to do well in other areas of CDL testing.

    Preparing for the Test: Handy Resources

    There is a lot of information that you will need to learn, if you don’t already know it, to pass the CDL general knowledge test. It is important to review information as much as possible until you know it well. A great way to get an idea of what you need to know is by buying or printing the commercial driver’s manual for your area. This will allow you to get an in depth view of the knowledge.

    You may want to call your local motor vehicle department and see if they have any additional information that you can use to learn what you need to pass the test and be a safe driver. Many times they offer free or low cost study guides that aim to educate you in the most comprehensive manner.

    Visit your library or your local book store. There is usually a wealth of information that can be found in these books. Not only will you get overviews of the tests, you can also take a look at sample tests and learn tricks for remembering certain things. The more information you are able to find and the more dedicated you are to learning it, the better you are going to do on the test.

    The internet can become your best friend when you are preparing for the test. If you spend any time searching the internet you will find that there are many websites that will give you tips on passing the test. Some will offer the information up for free and others will require you to pay a small sum for the information. You will need to pick and choose but when combined with traditional study methods, they can help you be very well prepared for the test.

    Practice Tests

    Taking the CDL general knowledge test comes with a lot of pressure for many people. With the pressure comes nerves and when most people are nervous they don’t test as well as they would otherwise. To get an idea not only of your knowledge but how well you will test with nerves, you should take practice tests. If you don’t do well on one of the practice tests, look over the questions that you missed and study these areas closely.

    The benefit of the practice tests is that they allow you to see where you need the most help. Continue taking the practice tests once a week and continue studying until you are able to pass the test with ease. This practice will also allow you to see that you really do know what you need to know to pass the test. This will boost your confidence so that when you take the real test you won’t be nearly as nervous, which will help you do well.

    There are many online CDL general knowledge tests for you to take advantage of. You should check with your motor vehicle department as well, because many offer a free practice test so you can get an idea of the types of questions that you will be asked. It will also allow you see how much you know.

    What You Need to Know

    Of course, everyone would like to know 100% of what is on the CDL general knowledge test. Everyone would like to get a perfect score and yet a lot of people do not. What you need to know to do your job well every day, every time is all of the information. What you need to know to pass the test amounts to 80%. In most areas you need to answer at least 80% of the questions in this section of the test correctly to pass.

    Again, this is where the practice tests will come in handy. When you do the practice tests you should actually ensure that you know more than 80%. The reason for this is that the practice tests are only a sampling of what will be on the real test. This is why it is a good idea to take several practice CDL general knowledge tests so you get an accurate idea of what will be covered.

    CDL General Knowledge Test Tips

    1. Go in with the thought that you will pass the test instead of assuming you will not.

    2. Find out how often you can take the test in the event that you do not pass the first time.

    3. Do not bring your cell phone into the test with you. If you do, make sure that the phone is off. If your cell phone rings or you pick it up, the test will be terminated.

    4. Read the question three times before you answer.

    5. Go with your gut when you choose your answer. If you are unsure, choose the best possible answer and move on.

    6. If you finish the test in plenty of time, be sure that you go back and check all of your answers.

    7. Don’t rush. Don’t be afraid to use up all of the allotted time to take the test. The more thorough you are with every question the more likely you are to do well.

    8. While thorough is good, don’t over think or second guess yourself.

    9. Listen to instructions before beginning so you do not disqualify yourself.

    10. If you get stressed, stop and take a deep breathe and continue.

    If you are on a mobile phone with a browser that does not support flash (such as the iPhone), it won’t work.


    laurie October 8, 2012 at 3:16 pm

    this practice test is the best one out there!!


    Carl October 10, 2012 at 10:40 am

    This test is the best. I took the 50 question test 4-5 times the day before and I passed with 48 out of 50. BIG KUDO’s


    Dwayne October 31, 2012 at 1:36 pm

    Very very helpful


    Bill November 24, 2012 at 11:55 am

    This is a great format- best one I’ve seen online. But- Will these answers be the same for every state. I need to pass the Nebraska test.


    Samuel Barradas November 25, 2012 at 1:49 am

    All states are testing the same information based on national guidelines. If you can reliably pass the tests on here, you can pass them in your state.


    Roger Heath November 25, 2012 at 8:56 am

    This test was very helpful, now I know I need to study more before taking the real test. Thank you.


    kay November 27, 2012 at 11:59 pm

    this test is a life saver better then any test on the market wish it had passenger and school bus ;)


    Sean December 6, 2012 at 12:07 am

    This is the best practice test exam out there for free. Is this test designed to be harder than the actual test? I find this practice exam harder than the exams found in most CDL books which is great. Being over prepared is the best way to go.


    John Clark December 10, 2012 at 2:06 pm

    Excellent test…best one on the web. I will definately be studying this more.


    Kenneth Reed December 17, 2012 at 11:15 pm

    This is the best practice test that I’ve come across and it is designed to help you get through the test with a better understanding of what you are doing as far as getting ready for the CDL test.


    gary ohler December 30, 2012 at 8:20 am

    This s the best prep out there, it doesn’t get any better than this.


    Danny January 2, 2013 at 8:48 am

    I ran across your site wile looking for some sample test questions for a HAZMAT endorsement for one of our drivers. Let me say that your site is great. It is a wonderful training tool and I will use it from now on to refresh drivers as well. Thanks–and keep up the good work.


    freddy Navarro January 4, 2013 at 10:10 am

    It is good so I recommended to everyone who want to pass the test


    quincy January 4, 2013 at 6:29 pm

    very tricky the test itself will get you ready and confident


    Patrick Wilson January 14, 2013 at 9:17 pm

    Awesome example questions. But it won’t load on smart phones. Would be even more helpful if I could study on the go. But still thanks for supplying us with the sample questions at all, very helpful! Thanks!


    Deb January 15, 2013 at 6:10 am

    This really helps a person pass the test, is a great study guide, AND “prepares” the nerves for taking the DMV CDL test. Thank you!!!


    JEFF HANSEN January 23, 2013 at 11:14 am

    I would like to know if you have, or will have a practice test for school bus drivers. Class B with P and S endorcements?


    Debbie August 13, 2013 at 8:20 am

    I studied these test to take my CDL class B license. You will be asked the questions you see on this site for school bus drivers. It was very very helpful to me. I spent 3 weeks studying and testing and could not pass the test. I studied the questions on this site and passed the General Knowledge test w/a 90!! You can find the other test just by typing in the name of the other test required for bus drivers in the search bar and will be able to find them. Took all my test and passed w/80’s and 90’s this site especially helped me pass my test. Preparing now to take my drivers test and be ready in 2 weeks to start driving a bus for my school district.


    Demetrius January 26, 2013 at 6:42 pm

    Thanks to this test I pass the written test in only two weeks of study and practices test!!! I recommend you study everyday for at an least an hour and take the practices test at least once a day and you shouldn’t have any problem taking the real test


    Mo January 28, 2013 at 6:04 pm

    Rod February 13, 2013 at 6:58 am

    The test are awesome, I have been out of trucking for 5 year’s and it had been over 20 year’s ago I took my CDL test. These test helped me get back up to speed so I could pass the CDL with ease.


    ed February 22, 2013 at 12:14 pm

    Best free test ive took online by far. Good job guys


    steven March 9, 2013 at 11:40 am

    hey guys i ve been studying the answers online like about 65 questions on the general knowledge test. but im unsure if its the same test or question i will be asked here in New York. Does anyone know anything about this? i dont want to go to the test and fail stupidly for thinking it was the same test i studied online… anyone knows?


    Samuel Barradas March 9, 2013 at 12:09 pm

    The way questions are worded won’t be exactly identical, but all the states follow the federal requirements for CDL testing, so the knowledge you need is the same for every state. If you can reliably pass the full practice test, you’ll have no problem with the real thing.


    Miguel Ramos March 14, 2013 at 10:53 am

    I used this website to take my general knowledge test, air breaks, and combo CDL Test. When i tell you that this site is the best practice test site. It really is! If you take 4-5 Tests a day, along with reading the CDL book from the DMV. There should be no reason you Fail. Thank you so much for these free practice test. It has made it so i can move forward at my job and become full time. ( $26/hr). Thank You!


    Miguel Ramos March 14, 2013 at 10:54 am

    And for those wondering what state i took the test in. Long Island, New York :)


    Doctor March 17, 2013 at 4:30 pm

    I just wanted to give everyone fair warning that some of the questions on this general knowledge test are slightly different from state to state. Example of this would be the question about when to test the parking break. In Ohio, where I am currently attending CDL school, section 2 of the manual, the general knowledge section, says to test the break while vehicle is moving slowly. Section 5, air brakes, says that you do it while the vehicle is parked. The book for Kentucky where I live and will be getting my license states in both sections that the vehicle should be parked when testing the parking break. Just make sure you study for your state and if you come up with two different answers follow the state’s book. You can always clarify with the testing station as well prior to going for the test. Good Luck!!!!!


    E. La Porte March 21, 2013 at 8:49 pm

    Thanks for posting this user friendly practice test. It is really helpful and although the questions won’t be the same it really helps with critical thinking, applying the process of elimination and test taking (something some of us haven’t done for years) as well as getting my confidence up. Nice work.


    Levi April 6, 2013 at 3:48 am

    I can’t thank you guys for putting these practice tests up!!!! They saved me. I took them until I was consistently passing with 96-98%, then marched into the licensing office and passed first time just breezing right through them.

    I only have one suggestion. On the 10 questions practice quizzes, instead of simply giving the correct answer, it would be super helpful to explain WHY it is the correct answer. I noticed that there was one or maybe two that did this.

    Thanks again! You saved me countless hours!


    robert May 27, 2013 at 3:59 pm

    helps so much, keep taking it untill u areonly missing 1 or 2 ?? the test change every time so u get a good feel of wht ur going to get


    JT May 28, 2013 at 10:40 am

    Do drivers need to carry a copy of the long form physical along with their card?


    Ohioman June 6, 2013 at 12:29 pm

    These questions really helped. Doing as many questions as I could and some reference to the drivers manual for CDL this helped ALOT, thank you.


    Gaylord Fleming July 1, 2013 at 4:56 pm
