Class B CDL for Oklahoma CDL Applicants

Oklahoma's energy sector drives strong demand for tanker and HazMat-endorsed operators across the oil patch. With oil and gas field services, agriculture and cattle, aerospace logistics driving much of the freight in Oklahoma, the Class B CDL material below is the part of the Oklahoma CDL that those employers screen for first.

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

Where Oklahoma drivers use this

  • Oil and gas field services: nearly every oilfield truck runs air brakes
  • Agriculture and cattle: livestock and reefer tractors on air brakes
  • Aerospace logistics: the heavy-haul tractors and straight trucks on aerospace plant routes
  • Wind energy equipment: heavy-haul tractors on wind projects
  • Oil and gas field services: water trucks, vacuum trucks, and single-unit haulers on well sites and plants

Most Oklahoma CDL work runs the I-35, I-40, I-44 corridors and the Oklahoma City area, so the examples in the practice questions lean on the vehicles and loads you will see there.

Testing, appointments, and fees are handled by Oklahoma Service Oklahoma. See the Oklahoma CDL classes and Oklahoma endorsements pages for the full licensing picture.
