Washington CDL Practice Tests - All Endorsements

The practice tests above are the fastest way to find the gaps in what you know before test day, and the free ones need no login, so you can jump in right now. One thing to get straight first: in Washington you deal with the Department of Licensing, the DOL, not a “DMV.” Getting the agency name right saves you a confused phone call later.

Everything begins with the General Knowledge written test. It runs 50 questions, and you pass at 80%, meaning 40 right out of 50. That threshold is a federal FMCSA standard that holds in all fifty states, not a Washington rule. Clearing it is what gets you a Commercial Learner’s Permit, which is why a Washington CDL practice test aimed at the permit and a CDL general knowledge test cover the exact same ground. And it does not matter which license you are after: Class A, B, and C drivers all take the same written test, with the class settled by your skills test and the truck you drive.

Washington freight shapes the endorsements worth chasing. Container traffic pours through the Ports of Seattle and Tacoma under the Northwest Seaport Alliance, and it moves inland on I-5 and I-90, so Combination Vehicles, Air Brakes, and Doubles/Triples get heavy use. Eastern Washington apples and wheat add agricultural hauling, Boeing work brings oversized aerospace loads, and tanker and HazMat routes run throughout. Because I-90 climbs Snoqualmie and other passes, mountain-grade braking, downhill gear selection, and knowing when to use a runaway ramp are real, honest concerns here. Each endorsement, from Passenger to School Bus, is a separate knowledge test.

When you study, chase understanding over rote recall. Pre-trip inspection, basic control, shifting, space and speed management, hazard perception, and emergency response all appear on the exam, and the Washington Commercial Driver Guide is the manual that spells out how Washington wants each one handled. Take a sample CDL exam, see where your score sags, then reread that chapter.

Once your practice runs come back solid, take the written test, collect your CLP, and schedule your CDL skills test with the Washington Department of Licensing when you are ready to prove it on the road.
