View All PlansWelcome to our second California CDL Combination Vehicles Practice Test! This intuitive tool has been designed to closely reflect the content and format of the official combination vehicles exam, helping you build the knowledge needed to achieve a passing score on your first attempt. This practice test features 30 multiple-choice questions based on Section 6 (Combination Vehicles) of the official California Commercial Driver Handbook (California CDL Handbook 2025). A minimum score of 80% is required to pass.
We recommend reading the official commercial driver handbook multiple times during your learning phase. Studying this manual is the first step toward becoming a skilled and knowledgeable commercial driver. Our Free California CDL Permit Practice Test can help you master this subject within a few weeks. Incorporate it into your daily study routine and watch your knowledge naturally improve over time.
Your personal Challenge Bank™ stores all the questions that have been answered incorrectly. This section includes detailed explanations and helpful insights. You should visit it at the end of your study session to identify areas that need improvement and learn from your mistakes. Review each question in your Challenge Bank and pay attention to the detailed explanation provided. Note this feedback in a notebook or notebook app and revisit the material during future training sessions. Once a question is answered correctly, it is automatically removed from your Challenge Bank.
This practice test has been recently updated for December 2025. It includes the latest updates brought by DMV rules or state law. For the most up-to-date information, you should check the official CA DMV website. Since you get unlimited attempts and nonstop access to this tool, there’s no limit to how often you can study.
Commercial driving theory is a complex subject that cannot be learned overnight. Building a successful career in this field is a gradual process that requires patience and steady effort. It’s crucial to dedicate plenty of time to your learning phase. Rather than rushing to master the material quickly, you should focus on making regular progress that will add up to a strong and lasting foundation of knowledge.
