Delaware CDL Endorsements
Endorsements are add-ons to your Delaware CDL that authorize specific vehicle types or cargo. Each requires a separate knowledge test, taken through Delaware Division of Motor Vehicles, and the endorsement codes are federal, so a Delaware endorsement is recognized in every state. With chemical and pharmaceutical manufacturing, port and container freight, food distribution shaping Delaware 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.
