Washington Class A CDL Practice Test and Study Guide

Use this Washington Class A CDL practice page to review the material represented in the saved 100-question bank before you take state knowledge or skills tests. The practice set spans general knowledge, combination vehicles, air brakes, hazardous materials, tank vehicles, doubles and triples, passenger, and school bus material. Those modules are included for broad study coverage; they do not mean every Class A applicant must qualify for every endorsement. Washington DOL sets the licensing and testing process, while federal Entry-Level Driver Training rules apply to many first-time Class A applicants and certain endorsement applicants. The practice questions are original study material, not official exam questions, and their 100-question A/B/C/D format is not the official Washington test format.

Who needs a Washington Class A CDL

Class A generally covers combination vehicles when the combined rating is at least 26,001 pounds and the towed unit is rated over 10,000 pounds. Washington requires a CDL for commercial vehicles that meet its weight, passenger, or hazardous-material thresholds. Applicants for a Washington CDL must be at least 18 and hold a valid Washington driver license; interstate commercial driving requires the driver to be at least 21. Always match the license class and any endorsements to the vehicle and work you actually plan to perform.

From application and CLP to the skills test

Washington directs applicants to bring a current driver license, Social Security number, and proof of U.S. citizenship or lawful permanent residency, then self-certify the type of commercial driving and satisfy applicable medical requirements. After passing the required knowledge tests, an applicant receives a commercial learner permit. For an original or upgraded CLP, Washington requires a 14-calendar-day wait before the skills test. The skills test has three parts in order: vehicle inspection, basic controls, and road test. Required state training and applicable federal ELDT must be completed before testing.

What the 100-question mixed practice bank covers

The saved bank contains 30 general-knowledge questions plus 10 questions each for air brakes, combination vehicles, hazardous materials, tank vehicles, doubles and triples, passenger, and school bus material. Across those modules, topics include vehicle inspection, braking systems, coupling and uncoupling, cargo management, commercial operating rules, hazardous conditions, emergencies, licensing responsibilities, passenger safety, and tank dynamics. Use the mixed bank to identify weak areas, then return to the Washington Commercial Driver Guide sections that apply to your actual Class A vehicle and endorsements.

Knowledge-test passing scores and endorsements

Washington lists the Class A general-knowledge test as 50 questions with 40 correct required to pass, and the Class A combination test as 20 questions with 16 correct required. Air-brake and endorsement knowledge tests have their own question counts and passing scores. A mixed practice bank can include those subjects for study breadth, but endorsements such as hazardous materials, tank, doubles and triples, passenger, and school bus apply only when the applicant intends to operate vehicles or perform work that requires them.

Current non-domicile processing notice

On the date this page was checked, Washington DOL stated that it had stopped processing non-domicile CLP and CDL transactions and had also stopped knowledge and skills testing for non-domiciled drivers. This is an operational status notice rather than a permanent study rule. Anyone who depends on a non-domicile pathway should check the current DOL notice before scheduling, paying fees, or making travel plans.

REQUIREMENTS OVERVIEW

Washington CDL Class A requirements

Requirements depend on the applicant and can change. Verify each item with the cited agency.

age

Washington CDL applicants

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.

documents

Applicants for an original Washington CDL or CLP

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.

tests

Class A applicants

Pass the knowledge tests required for the Class A vehicle and any applicable endorsements. Washington lists general knowledge and combination as Class A knowledge tests; air-brake or endorsement tests apply when relevant to the vehicle or credential sought.

tests

Applicants who must take a CDL skills test

After the required training is recorded and the CLP waiting period is satisfied, pass the three skills-test components in order: vehicle inspection, basic controls, and road test.

passing

Class A knowledge-test applicants

Washington lists a passing score of 40 out of 50 for CDL general knowledge and 16 out of 20 for the Class A combination knowledge test.

passing

CDL skills-test applicants

You must pass all three CDL skills-test components in order. Washington does not present a single overall numeric passing percentage for the full three-part skills test on the cited skills-test page.

applicability

First-time Class A applicants and drivers upgrading from Class B to Class A

Federal Entry-Level Driver Training rules apply to first-time Class A or Class B applicants and to drivers upgrading from Class B to Class A, subject to the federal exceptions described by FMCSA. Washington also requires state training for drivers getting or upgrading a CDL or adding endorsements.

applicability

Applicants considering endorsement material in this mixed practice bank

Hazardous materials, tank, doubles/triples, passenger, and school-bus material is included for study breadth, but those endorsements are not automatically required for every Class A CDL holder; testing depends on the vehicle and endorsement sought.

applicability

Non-domiciled CDL or CLP applicants

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 DOL notice for current availability before relying on that pathway.
