To get a CDL and drive any type of commercial vehicle, you must take and pass the General Knowledge test. You’ll be tested on general trucking knowledge, driving safely and transporting cargo safely, taken from sections 1, 2, and 3 of your state CDL manual. Once again, you MUST pass the official state CDL General Knowledge exam to get your CDL.

You must have a CDL with a Hazmat (Hazardous Materials) Endorsement before you drive any size vehicle that is used in the transport of any material that requires hazardous material placarding or any quantity of a material listed as a select agent or toxin in 42 CFR 93.

To drive a truck or bus with air brakes, you need to know the information in the CDL Air Brakes section of the CDL manual. To pull a trailer with air brakes, you also need to know the information in the Combination Vehicles section. Air brakes use compressed air to make the brakes work. Air brakes are a good and safe way of stopping large and heavy vehicles, but the brakes must be well maintained and used properly.

The Air Brakes CDL Practice Test covers:
Air Brake System Parts, Dual Air Brake SystemsInspecting Air Brakes and Using Air Brakes.

To drive a commercial vehicle AND pull any kind of trailer, you must pass the Combination Vehicles written CDL exam. Combination vehicles are usually heavier, longer, and require more driving skill than single commercial vehicles. This means that drivers of combination vehicles need more knowledge and skill than drivers of single vehicles. You must understand the important safety factors that apply specifically to combination vehicles. Our CDL Combination Vehicles practice tests will prepare you to pass the exam.

Want to haul tankers? A tank vehicles endorsement is required for certain vehicles that transport liquids or gases. Our Tank Vehicles practice tests will prepare you to get this CDL endorsement. The liquid or gas does not have to be a hazardous material. A tanker endorsement is only required if your vehicle needs a Class A or B CDL and you want to haul a liquid or liquid gas in a permanently mounted cargo tank rated at 119 gallons or more or a portable tank rated at 1,000 gallons or more.

To pass the CDL Doubles and Triples written exam, you’ll need to demonstrate understanding about how important safety is when driving with more than one trailer. Drivers must also know how to couple and uncouple correctly, and about inspecting doubles and triples. When pulling 2 or 3 trailers, there are more things that can go wrong, as they are less stable than other commercial vehicles.

We Now Have 3 CDL Testing Modes to Help You Prepare to Pass Your Official DMV Exams!

Our test questions and answers will thoroughly prepare you to Pass EACH U.S. State’s official DMV exams. To get a Class A, Class B, or a Class C CDL or CLP (Commercial Learner’s Permit), you must pass these tests. To use our 3 Testing Mode sytem as a CDL study guide, see How to Pass the Official State CDL Exams. Also see classes of licenses, and CDL endorsements. Truck driving schools across the country are now sending their students to our site to prepare for the official DMV permit tests. That’s because our new testing mode system makes our practice tests a complete CDL course – but without the big cost you’ll find with other online courses!​

Classic Mode

In our original Classic Mode, each test has a series of multiple choice questions that are all on one page. No need to study the guide beforehand, but it'll be helpful to open up your state manual in another tab and have it available, because you'll need it in Practice Mode. Going through the questions in this way will quickly give you an idea where you stand and how much preparation you're likely to need when you move on to Practice Mode. Yes, see how well you do, but try not to stress out about any mistakes at this point.

Practice Mode

In this mode, you get instant correct answers after every question AND a CDL reference. This points you to the exact location in your official state CDL manual so you can immediately see for yourself where the question came from and reread that section if necessary, which cements that information in your head. You'll be confident that each answer is accurate because it's RIGHT THERE in your official state handbook and THAT'S what you're tested on!

Exam Mode

Each Exam Mode practice test is timed and you get your grade and results only after you've finished each test. This is very similar to the official state DMV written exams!

After you've completed each test, check out your free assessment report, which tells you which answers you got correct and incorrect along with each question. As with all of our tests, retake tests as needed. Good Luck!

What Makes Our Tests Better than Other Testing Sites?

Yes, our tests are FREE, but there are many sites out there with free practice tests. The QUALITY of the tests is what matters most! These tests must be accurate, challenging, and up to date (2018) with the latest Federal Guidelines found in your official state handbook. We make sure that they are. Take some practice tests and try us. If you believe you find an error, or something that’s confusing, email us and we will get right back to you. But these tests have been taken millions of times and you can rest assured that they are correct! You’ll get better quality test preparation than you’ll find on other online sites, but with one big bonus… these tests are still FREE.

Do the Official CDL Exams Vary From State To State?

Nope. Regardless of what state you live in, each and every state’s written CDL exam is based on Federal Guidelines taken from the same information. Think about it, do you really believe that the way you drive a big truck changes from one state to the next? Is there a different braking technique on a mountain in Colorado than there is in Alaska? Are Hazmat placards placed in a different location on your trailer depending on what state you’re in? Not so much. Practicing with our CDL tests will prepare you to pass EVERY CDL written exam, in ALL states!

That being said, it’s essential that you read your state CDL manual – instant access here. Your CDL manual has specific information for your state, such as fees, testing locations, phone numbers for your local testing centers, and their hours of testing and service. They may also offer CDL study guides that could further prepare you for the CDL permit exam.

Are These the Same Exact Test Questions I’ll Get on the Official Exams?

Each of our tests are similar, but not necessarily the exact same as the official state permit test you’ll have to take and pass to get your commercial drivers license (CDL). The official state exams change often to prevent passing along of the answers. But by practicing with our tests in conjunction with studying the corresponding sections of your state CDL handbook, you’ll be well on your way to passing the written exams and getting your CDL.
