Washington CDL Class B to A Upgrade Study Material

Class B to Class A Upgrade for Washington CDL Applicants

Washington's Port of Seattle and aerospace manufacturing create strong CDL demand across the Pacific Northwest. With port and intermodal freight, aerospace manufacturing, agriculture and produce driving much of the freight in Washington, the Class B to Class A Upgrade material below is the part of the Washington CDL that those employers screen for first.

The Washington Class B to A upgrade: Combination Vehicles and Air Brakes knowledge tests at Washington Department of Licensing, then a Class A skills test. Since February 2022, ELDT theory and behind-the-wheel training must also be logged with an FMCSA-registered provider before Washington Department of Licensing will schedule the test.

Where Washington drivers use this

• Lumber and forest products: dump trucks, mixers, and flatbed tractors on construction routes
• Almost every Class A and Class B vehicle in Washington; skip this test and your CDL carries an L restriction
• Port and intermodal freight: container drayage between the ports and inland rail yards
• Agriculture and produce: refrigerated (reefer) loads of produce and food moving to distribution centers and out of state
• Port and intermodal freight: container drayage between the ports, rail ramps, and warehouses

Most Washington CDL work runs the I-5, I-90, I-82 corridors and the Olympia 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 Washington Department of Licensing. See the Washington CDL classes and Washington endorsements pages for the full licensing picture.
