Updated for March 2025

The required General Knowledge test for the Maryland Commercial Driver’s License is not a gimme. It’s 50 relatively high level, multiple-choice, questions that are more than just common knowledge. You only have an hour to take the test and need to get over 40 right (an 80%) to pass. Fail and you’ll have to come back to the MVA (and take a number and wait in line) another day. That’s why you’ll want to study the concepts pretty closely to make sure you have all the details down. That means getting the official Maryland commercial driver’s manual and giving it a good read and then taking some practice tests until you are confident you can successfully pass the exam in person. Our practice exams have questions that look and feel like the real thing, and with our hint system and score tracking it’s easy to see where you need to focus your studying efforts. But the test isn’t the only hurdle to your CDL — before they even let you take the exam, you need to get your paperwork in order. There are three main elements you’ll need for the Maryland DMV. First you need a valid current driver’s license and proof of citizenship or permanent legal residency. For this last one, a green card, social security card, or birth certificate are best. But you also need proof that you are physically qualified to drive a commercial vehicle. For this the Maryland MVA asks that you present a Medical Examiner’s Certificate. Also known as a DOT card, the certificate can be obtained only from a licensed medical examiner as listed on the Federal Motor Carrier Safety Administration (FMCSA) National Registry. The certificate is usually good for two years, unless you have a condition that needs monitoring, like high blood pressure. Once you have all that together, along with everything you’ve prepared mentally, you should be all set for success. Start preparing today by studying our CDL General Knowledge Exam Simulator!

At Driving-Tests.org, we understand the importance of reliable and accurate practice tests to help you prepare for your DMV exam. That's why we've developed a meticulous process to create and continually update our practice questions, ensuring they reflect the most current driving laws and regulations.

Here's an inside look at how we maintain the highest quality in our practice tests.

Content Creation and Verification Process

Alignment with Official Manuals:
Every question we develop is based on the most recent version of each state's official driving manual. Our team regularly monitors each state DMV's website for the latest updates to ensure our practice tests are always aligned with the most current information.
Community Feedback Integration:
We leverage feedback from our vast community of users to understand which topics are most frequently tested. This helps us focus on the areas that are most relevant and beneficial for your preparation.
Expert Content Creation:
Our in-house editor, Steven, who has extensive experience in driver education, crafts each question with precision. He conducts a thorough review of each question against the official manuals to ensure accuracy.
Rigorous Review Process:
Once Steven has finalized a set of questions, our team conducts a joint review session. This second level of scrutiny involves content accuracy, proofreading, and fact-checking to eliminate any errors.
User Feedback Mechanism:
After a question goes live on our site, we keep the lines of communication open. Each question features a feedback button, inviting users to report any issues or errors. This continuous feedback loop allows us to address and rectify any concerns promptly.
Responsive Updates:
In line with our commitment to accuracy, we quickly update our practice questions to reflect any changes in the DMV manuals. Additionally, we update the free electronic copy of the state's driver's license manuals on our site, typically within a few days after the DMV publishes them.

Our thorough quality control process ensures that you have access to practice tests that are as accurate and up-to-date as possible. We believe in the power of well-prepared drivers and are dedicated to providing you with the best study tools to help you succeed on your DMV exam.
