Must-know rules

Massachusetts has no separate truck speed limit that I could confirm, but it has a strict 5-minute idling rule, a ban on all hazmat cargo and cargo tankers in the Boston tunnels, and low tunnel clearances (12'6" at Sumner and Callahan). Fuel-tax filing runs through the state Department of Revenue, and Turnpike miles are treated differently for IFTA. I could not confirm winter chain or traction rules, weigh station rules, or whether the state has a weight-distance tax, so those are left out.

• Must knowHazmat and tankers in Boston tunnels

  All hazardous cargo and cargo tankers are prohibited from the Boston Tunnels (the underground highway system). MassDOT also lists restricted and prescribed non-radioactive hazmat routes for Metro-Boston. Check its route designation page before you route a load.

• Must knowIdling limit

  Idling longer than five minutes while stopped is against state law (M.G.L. c. 90, s. 16A) and the MassDEP rule (310 CMR 7.11). MassDEP says the law lists three exemptions. The MassDEP FAQ covers when idling counts as necessary.

Fees and DOT requirements

Massachusetts CDL fees are low: $75 for a 5-year Class A or Class B license. Heavy-truck registration is priced by registered gross weight, which you choose yourself. The official fee schedule I could access did not show the commercial per-1,000-lb rates, so I left the registration dollar amounts null. Intrastate carriers must display a USDOT number if their vehicles are 10,001 lb or more. I found no state operating authority for general-freight for-hire carriers, though household-goods and pass

Class B CDL

$75 for 5 years (about $15 a year)
Commercial learner's permit application: $30 (permitsmash.com, a secondary source citing the RMV fee schedule). CDL road test: $35, payable online (mass.gov). Each endorsement: $10 if added with the permit application, $30 if added after the permit is issued (mass.gov). The $30 general knowledge tes Source

Class A CDL

$75 for 5 years (about $15 a year)
The permit, road test and endorsement fees are the same as for Class B. A Class A road test also requires the concurrent endorsement tests (mass.gov road test page). Upgrading from Class B to Class A requires ELDT. The fee for the Class A road test is $35. Source

How registration is figured

Commercial and trailer fees are determined by weight. The fee is based on the 'registered gross weight', which is the vehicle weight plus the maximum load the owner intends to carry at one time. The registrant chooses this weight, and operating above it is a violation (official RMV Schedule of Fees)
I did not compute dollar amounts because the official schedule text I retrieved did not state the commercial rates or how fractions of 1,000 lb are handled. It is also unclear how a tractor and its trailer are charged separately. Secondary sources mention a $300 five-year semi-trailer registration, which I could not verify officially. Check the commercial section of the RMV Schedule of Fees. For i Source

Intrastate operating authority

Not required for intrastate carriers.
The only source I found saying general for-hire freight needs no state authority is J.J. Keller's compliance summary, dated January 2024. It is not an official state source, and I could not find a Massachusetts statute or agency page stating this directly. Treat it as medium confidence. The same source says household-goods carriers must file proof of insurance with the DPU, with a $10,000 cargo li Source Non-government source

State DOT requirements

• Must knowIntrastate USDOT number

  Under 540 CMR 2.22, intrastate vehicles with a GVWR or GCWR of 10,001 lb or more must have a USDOT number and display it. The same applies to any vehicle carrying placardable hazmat and to vehicles designed for more than 15 passengers. The number is free from FMCSA, and violations can bring fines or out-of-service orders.
