Use this Washington Class C CDL practice page to review the material represented in the saved 100-question bank before required state tests. Washington defines Class C around certain commercial vehicles that do not meet the Class A or B weight definitions but carry 16 or more people including the driver or transport hazardous materials, with the proper endorsement required. The practice set covers general knowledge, air brakes, hazardous materials, tank vehicles, passenger, and school bus material. Those modules provide study coverage and do not mean every Class C applicant needs every specialized test. Washington also has state training requirements for Class C, while federal Entry-Level Driver Training applies to first-time passenger, school-bus, or hazardous-material endorsement applicants rather than to Class C solely because of the class. The questions are original study material, not official exam questions, and the bank's 100-question four-option format is not the official Washington test format.
Every test draws only from the Washington CDL Class C question bank.
Use this overview together with the latest official guidance linked below.
Washington identifies Class C vehicles as those carrying 16 or more people including the driver or vehicles carrying hazardous materials when the vehicle does not fall into Class A or Class B. These Class C uses require the appropriate endorsement. Match the class and endorsements to the actual vehicle, passenger service, cargo, braking system, and tank configuration you plan to operate.
Washington allows a person age 18 or older with a valid Washington driver license to apply for a CDL, while interstate commercial driving requires the driver to be at least 21. The application steps call for a current driver license, Social Security number, and proof of U.S. citizenship or lawful permanent residency. Applicants also self-certify the type of commercial driving and must satisfy applicable medical requirements before issuance.
Washington lists the CDL general-knowledge test for Classes A, B, and C as 50 questions with 40 correct required to pass. Additional tests depend on the vehicle and endorsements. The saved practice bank contains 38 general-knowledge questions, 13 air-brake questions, 13 hazardous-materials questions, and 12 questions each for tank vehicles, passenger, and school bus. Use the mixed bank to identify weak areas, then study the official guide sections that match the Class C vehicle and endorsements you actually need.
Washington states that applicants getting a CDL must meet state training requirements, and it lists 80 total training hours for Class C. After knowledge testing and issuance of the appropriate commercial learner permit, the skills test cannot be taken until the required waiting and training conditions are met. Washington describes the skills test as three parts taken in order: vehicle inspection, basic controls, and road test.
Class C commonly depends on endorsement applicability rather than vehicle weight alone. Passenger, school-bus, hazardous-materials, tank, and air-brake requirements apply only when the vehicle or operation calls for them. Federal ELDT rules apply to a first-time passenger, school-bus, or hazardous-material endorsement applicant, subject to FMCSA exceptions. FMCSA's first-time CDL class rule names Class A and Class B, not Class C solely by class.
On the checked date, Washington DOL stated that it had stopped processing non-domicile commercial learner permit and CDL transactions and had also stopped knowledge and skills testing for non-domiciled drivers. This is an operational status notice, not a permanent study rule. Applicants who depend on a non-domicile pathway should verify the current DOL notice before scheduling tests, arranging training, or making travel plans.
Requirements depend on the applicant and can change. Verify each item with the cited agency.
You may apply for a Washington CDL if you are 18 or older, have a valid Washington driver license, and do not have a lifetime driver-license disqualification. Interstate commercial driving requires the driver to be at least 21.
Bring your current driver license, Social Security number, and proof of U.S. citizenship or lawful permanent residency. Washington also requires self-certification of the type of commercial driving and applicable medical documentation before issuance.
Pass the CDL general-knowledge test and any additional knowledge tests that apply to the vehicle or endorsements sought. Passenger, school bus, air brakes, tank vehicle, and hazardous materials tests apply according to the credential and vehicle.
After the commercial learner permit, required waiting period, and required training conditions are satisfied, pass the three CDL skills-test components in order: vehicle inspection, basic controls, and road test.
Washington lists 40 out of 50 as the passing score for CDL general knowledge. It lists 20 out of 25 for air brakes, 16 out of 20 for passenger, school bus, and tank vehicle tests, and 24 out of 30 for hazardous materials when those tests apply.
Washington lists 80 total hours as the minimum Class C training requirement for applicants who must meet the state's CDL training rules.
Federal Entry-Level Driver Training rules apply to first-time applicants for passenger, school-bus, or hazardous-material endorsements, subject to FMCSA exceptions. FMCSA does not list first-time Class C by itself as a class-based ELDT trigger.
Air-brake, hazardous-materials, tank, passenger, and school-bus material is included for broad study coverage, but these specialized tests or endorsements are not automatically required for every Class C applicant; applicability depends on the vehicle and operation.
As of the checked date, Washington DOL states that it has stopped processing non-domicile CLP/CDL transactions and stopped knowledge and skills testing for non-domiciled drivers. Check the current DOL notice before relying on that pathway.
