Delaware CDL Class B Study Material

Class B CDL for Delaware CDL Applicants

Delaware handles heavy chemical and pharmaceutical freight along the busy I-95 Northeast corridor. With chemical and pharmaceutical manufacturing, port and container freight, food distribution driving much of the freight in Delaware, the Class B CDL material below is the part of the Delaware CDL that those employers screen for first.

Class B in Delaware is General Knowledge plus Air Brakes, followed by a skills test in a straight truck or bus. Because so many Delaware Class B jobs are buses, it also covers the Passenger and School Bus tests.

Where Delaware drivers use this

• Automotive parts: straight-truck parts delivery on local routes
• Transit and school districts: city buses and full-size school buses across Delaware (P and S endorsements)
• Automotive parts: the tractors and straight trucks on every plant route
• Almost every Class A and Class B vehicle in Delaware; skip this test and your CDL carries an L restriction
• Chemical and pharmaceutical manufacturing: local delivery straight trucks and last-mile box trucks

Most Delaware CDL work runs the I-95, I-295 corridors and the Dover area, so the examples in the practice questions lean on the vehicles and loads you will see there.
