Updated for March 2025

How much do you know about emergency ramps? Or the number of seconds it takes a tractor trailer to clear a set of train tracks? If the answer is you aren’t very sure, you’ll need to get to studying the official Nevada Commercial Driver’s manual if you want to pass the relatively tricky General Knowledge exam. The test is 50 multiple-choice questions with a strict 1 hour time limitation. If you get more than 10 of those questions wrong (or less than an 80%) you fail the test and have to return another day. That means the whole process of waiting at the DMV all over again. If you want to make sure you have the knowledge you need to succeed the first time, we suggest taking our CDL General Knowledge practice tests. Our tests show you the format of the questions and in many cases the exact concepts that the exam at the DMV will cover. And with hints and score tracking, our practice tests are designed to make sure you have everything down pat before you go. However, knowledge is not the only thing you need to bring to the Nevada DMV. In addition, you’ll need some paperwork, before they even show you the test. First they will expect to see proof that you are physically qualified to drive a commercial vehicle. This comes in the form of a Medical Examiner’s Certificate (also known as a DOT Card). In order to obtain one you must visit a licensed medical examiner listed on the Federal Motor Carrier Safety Administration (FMCSA) National Registry. In addition, you need a valid current driver’s license as well as a proof of residency or citizenship like a birth certificate or social security card. With all that together, and what you learned taking the practice exams you’ll be confident to get your CDL the first time out.

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.
