Massachusetts CDL Practice Test
Free practice questions for the Massachusetts commercial driver license written exams — general knowledge, air brakes, combination vehicles, and every endorsement.
The Massachusetts Registry of Motor Vehicles (RMV) is responsible for driver licensing, vehicle registration, and motor vehicle inspection throughout the Commonwealth. Massachusetts has modernized its licensing system with the myRMV online portal, allowing residents to complete more than 60 transactions from home without visiting an office. The state's Class D learner's permit program begins at age 16 and includes a structured 25-question written knowledge test that candidates must complete within 25 minutes. Massachusetts emphasizes safe driving through its comprehensive testing of traffic laws, Junior Operator Law (JOL) requirements, impaired driving consequences, and pedestrian/bicycle safety. The RMV operates service centers statewide and has invested in technology to streamline the licensing process. Whether you're a teenager obtaining your first permit or an adult resident, Massachusetts provides clear pathways to licensing with extensive study materials and online resources available through the official RMV website.
About this section of the Massachusetts test
Massachusetts' commercial driver license program requires a written knowledge test covering cargo safety, vehicle inspections, air brakes (if applicable), and combination vehicles. The test consists of 50 questions, and you must score at least 80% to pass. Applicants must first obtain a Commercial Learner's Permit (CLP) and hold it for at least 14 days before taking the road skills test. Massachusetts offers CDL tests in English, Spanish, and Portuguese. All CDL endorsements (hazmat, tanker, double/triple trailers, passenger) require passing additional exams specific to those vehicle types.
