From the steeply-graded hilly regions, like Jacob’s Ladder near the Mass Pike, to the coastal areas, you’ll find a good mix of rural and urban (very urban…Boston urban!) driving in Massachusetts. You must be considering adding the Hazardous Materials (Hazmat) endorsement to your Commercial Driver’s License (CDL) or you wouldn’t be here. What a fabulous way to add marketability and a potential increase in earnings to your career! If you don’t have the Hazmat endorsement, you are not allowed to transport materials that the U.S. government has deemed hazardous. That’s an entire class of opportunities you’ll be locked out of! Once you have the endorsement, the materials you can transport range from explosives and certain types of fuel to industrial chemicals, radioactive materials and infectious substances. But don’t stress: the endorsement process makes ensuring your safety and the people and environment in your driving area of the utmost importance.
The minimum age for the Hazmat endorsement in the Bay State is 21. To add this endorsement, you’ll need to pass a Transportation Security Administration (TSA) fingerprinting and background check and the RMV knowledge test. The knowledge test covers federal regulations, substance handling, and a host of other topics and is made up of 30 questions. It must be passed with a score of at least 80% (24 out of 30 answers must be correct) (Massachusetts CDL Handbook 2026).

In Massachusetts, there are lots of industries that require a Hazmat endorsement, including chemicals used in manufacturing, gasoline, propane, pesticides, and materials associated with the state’s large pharmaceutical and healthcare industries. Companies like Boston Scientific (Marlborough), General Electric (Boston), and Thermo Fisher Scientific (Waltham) are just a few of the ones that require this endorsement. Sounds pretty lucrative, right? Maybe a bit daunting? Let’s un-daunt it for you!
