Vermont CDL Endorsements
Endorsements are add-ons to your Vermont CDL that authorize specific vehicle types or cargo. Each requires a separate knowledge test, taken through Vermont Department of Motor Vehicles, and the endorsement codes are federal, so a Vermont endorsement is recognized in every state. With dairy and agriculture, maple and specialty food logistics, granite and stone shaping Vermont 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.
