New Hampshire CDL Endorsements
Endorsements are add-ons to your New Hampshire CDL that authorize specific vehicle types or cargo. Each requires a separate knowledge test, taken through New Hampshire Division of Motor Vehicles, and the endorsement codes are federal, so a New Hampshire endorsement is recognized in every state. With electronics and manufacturing, granite and construction materials, tourism and resort supply shaping New Hampshire freight, the examples under each endorsement show where that endorsement pays off locally.
Not all endorsements apply to every CDL class. Use the CDL Selector to find what you need.
