Classes
CDL classes available in Hawaii
Hawaii follows the federal CDL class structure. Class A generally covers combination vehicles such as tractor-trailers. Class B covers heavy single vehicles such as straight trucks and many buses. Class C applies when the vehicle does not meet Class A or B weight thresholds but carries placarded hazardous materials or enough passengers to require a CDL.
Endorsements can still change what you must test for. Passenger, school bus, tanker, hazmat, air brakes, and combination-vehicle work may require extra knowledge tests or restrictions to be removed.
