Get your Massachusetts CDL
Pay the ~$55 CDL fee and you're licensed to drive commercially.
Massachusetts CDL fees come to about $85 total — roughly $30 for the commercial learner's permit (CLP) and $55 for the CDL itself, paid at Massachusetts Registry of Motor Vehicles (RMV). Testing and endorsement fees can add to this, so always confirm current amounts with Massachusetts Registry of Motor Vehicles (RMV).
You need 80% on each CDL knowledge section. Massachusetts uses the same FMCSA-standardized question pool as every other state, so General Knowledge, Air Brakes, Combination Vehicles, and the endorsement tests are federally consistent.
Massachusetts issues a CDL at 18 for driving within the state (intrastate) and 21 for driving across state lines (interstate) or hauling hazardous materials.
At least 14 days. You pass the knowledge test first to earn your CLP, hold it for 14 days while practicing with a licensed CDL holder, then take the behind-the-wheel skills test.
