Maine CDL Practice Test — General Knowledge, Air Brakes & Endorsements (2026)
Maine's commercial driver license program requires passing a written knowledge test with a minimum score of 80% (answering at least 40 questions correctly). Applicants must first obtain a Commercial Learner's Permit (CLP) and hold it for at least two weeks before taking the skills test. The written test is administered electronically at BMV offices throughout Maine. Your CLP is valid for 180 days, during which you can practice driving a commercial motor vehicle with a certified CDL holder (20+ years old, or 22+ for school bus) accompanying you. The test covers commercial motor vehicle operation, safety regulations, traffic laws, federal regulations, and Maine-specific rules.
