View All PlansDriving combination vehicles requires advanced driving skills and thorough knowledge. To begin your trucking career, you must get a Class A CDL (Commercial Driver’s License). Before obtaining a CDL, applicants must be at least 18 to get a CLP (Commercial Learner’s Permit). However, driving professionally across state lines, transporting passengers, and carrying hazardous materials are only allowed for commercial drivers aged 21 and older.
Before you can get a CLP, you must pass the official general knowledge exam. Your knowledge of commercial driving regulations, emergency procedures, and pre-trip inspections will be evaluated through 50 multiple-choice questions. A minimum score of 80% is required to pass, leaving little room for error. Our Free Maine CDL Permit Practice Test can help you master general commercial driving theory and achieve a passing score on your first attempt.
The official combination vehicles knowledge exam is the second written test you must pass. It consists of 20 questions based on Section 6 (Combination Vehicles) of the official Commercial Driver License Manual (Maine CDL Handbook 2025). This Maine CDL Combination Vehicles Practice Test is an efficient educational resource that can help you master this subject through active learning. You get unlimited attempts and nonstop access to train with this tool as often as you wish, giving you the flexibility you’ve been looking for.
We have recently updated this practice test for December 2025. You will always practice with the latest version, which accurately includes the most recent updates brought by DMV rules or state law. However, you should always refer to the official DMV website for the latest information.
Since your knowledge can only be improved gradually, you should avoid rushing. Many of our practice tests are untimed, including this one. Carefully consider each answer choice before you select one. Additionally, you can ask “Officer Frank,” your AI-powered assistant, for hints, real-life examples, and helpful insight.
The most determined students adopt a smarter approach in their learning phase. With our practice tests, you’re preparing for your theory exams while also building a strong foundation for your dream career.
