In Arizona, the application process for a Commercial Driver’s License (CDL) begins with gathering the necessary documents, passing a medical examination, and paying the application fees. All candidates must possess a valid Arizona driver’s license and have at least one year of driving experience. Before taking the CDL skills test, applicants must obtain a Commercial Learner’s Permit (CLP) by passing the official CDL permit test. To add specific endorsements to your CDL, you will need to take additional written tests for those endorsements. Although they are optional for obtaining the CLP, you can take them to expand your career opportunities.
The CDL general knowledge test consists of 50 multiple-choice questions based on the official Arizona commercial driver license manual (Arizona CDL Handbook 2025). The CLP is valid for 12 months, and you must wait at least 14 days before taking the CDL skills test. Entry-Level Driver Training (ELDT) from a provider listed in FMCSA’s Training Provider Registry (TPR) is also mandatory.
Simulate the official testing experience on your device with our Arizona CDL General Knowledge Exam Simulator. This intuitive tool has been designed to help students overcome test anxiety by familiarizing themselves with the content and format of the official exam. All 50 questions have multiple answer choices, but only one is correct. Think as long as you want before you select an answer. There is no countdown to pressure you, as we have omitted any timer from our simulator. With unlimited attempts and browser-based access, you can train anytime from anywhere in the world. If you find yourself in a distracting environment, we recommend using headphones and activating the voice-over feature. This function uses an artificial voice to read the questions and answer choices aloud, which can significantly increase your focus.
Please remember that this simulator will not provide any feedback. If you make too many mistakes, the test ends immediately. Before you begin a new session, visit your Challenge Bank, which contains the questions you got wrong with detailed explanations that help you learn from your mistakes. Start today and train with this tool for several weeks. When you consistently get passing scores, it is a strong indication that you’re ready for the official exam.
