Have you always wanted to drive one of those heavy trucks you saw as a kid? Or perhaps the school bus driver inspired you to follow their career path once you grew up. Make your dream career a reality and begin the process of obtaining a Colorado Commercial Driver’s License (CDL) today. Your determination to achieve your professional goals will play a crucial role in this journey, but you must also meet several licensing requirements. To obtain a Commercial Learner’s Permit (CLP), you must obtain a valid DMV Medical Examiner’s Certificate, provide the necessary documentation, pay the license fees, and pass the official CDL General Knowledge (permit) test. This exam consists of 50 questions based on the official Colorado commercial driver license manual (Colorado CDL Handbook 2026). After holding a CLP for at least 14 days and completing Entry-Level Driver Training (ELDT) from a registered training provider, you can schedule and take the CDL skills test.

If you have difficulty understanding the various aspects of commercial driving theory, you should adopt a smarter approach and change your study routine. You cannot become an expert overnight, so we recommend dedicating a few days to understanding the basic concepts and several more weeks to master this subject.

When you’re ready, take our Colorado CDL General Knowledge Exam Simulator to see if you can pass the official exam. This intuitive tool is current for February 2026 and includes the latest updates brought by DMV rules or state law. All 50 questions have multiple answer choices, but only one is correct.
