Massachusetts CDL Practice Test and Test Prep (2026)
Massachusetts gives CDL tests through Massachusetts Registry of Motor Vehicles (RMV). Here is what you will be tested on, which of our practice quizzes match each test, and what the skills test involves in Massachusetts.
Knowledge tests for a Massachusetts permit
- General Knowledge (50 questions, 40 to pass; all applicants) — practice General Knowledge (60 questions)
- Combination Vehicles (Class A) — practice Combination Vehicles (30 questions)
- Air Brakes (if your vehicle has them) — practice Air Brakes (40 questions)
- Any endorsement tests you need (P, S, H, N, T)
Permit minimum age: 18 (in-state driving) or 21 (interstate). Holding period before the skills test: 14 days. Permit validity: 180 days.
Massachusetts endorsement tests and practice
- Hazmat (H) practice
Massachusetts notes for this endorsement
Massachusetts is NOT a TSA self-managed state. The hazmat written exam requires a TSA Security Threat Assessment plus (for first-timers) hazmat ELDT; fingerprinting/background check is done through the federal TSA program via IdentoGO (call 855-347-8371 or visit a TSA enrollment center). Results can take 60+ days, and the endorsement isn't auto-renewed — you re-clear TSA and re-pass the exam at each renewal.
- Tanker (N) practice
Massachusetts notes for this endorsement
Tank; written exam only.
- Passenger (P) practice
Massachusetts notes for this endorsement
Passenger; written exam plus a road test in a vehicle seating 16+.
- School bus (S) practice
Massachusetts notes for this endorsement
School bus; written exam plus a road test. Note Massachusetts also has separate state credentials — a 7D School Pupil Transport Certificate and a School Bus Certificate — with their own medical standards; depending on the vehicle you may need one of these in addition to the CDL 'S' endorsement.
- Doubles/triples (T) practice
Massachusetts notes for this endorsement
Double/triple trailers; written exam only, Class A only, and not required to obtain Class A.
The Massachusetts skills test
Components: Pre-trip vehicle inspection, Basic vehicle control, On-road driving test.
Test vehicle: You must bring a vehicle representing the class you're applying for — valid registration, current inspection sticker, GVWR documentation, no hazmat/unstable loads (a P vehicle must seat 16+). A sponsor must accompany you: at least 21, holding a valid U.S. CDL with proper endorsements for at least a year, and a current DOT medical card if required.
Where and how to book: Massachusetts commercial road tests are conducted by the State Police, not third-party testers. You schedule only by calling (857) 368-7381, a line monitored by the State Police. No more than six CDL skills tests are allowed in any 12-month period.
Waits and retests: Tests are scheduled solely through the State Police phone line; the RMV publishes a list of Class A/B/C testing sites but no official wait times.
Practice the inspection part with our pre-trip inspection guide. Research dated 2026-07-20; confirm testing details with Massachusetts.
