Your Path to a Commercial Driver's License
To get a CDL, you must first study for and pass the permit exam at the DMV. After you receive your permit, you can take commercial vehicle driving classes and complete the required training. The final step is passing the official driving exam to earn your CDL. Our practice tests help you prepare for the DMV permit exam with real-style questions, and we also provide extra study materials and helpful resources to guide you through the process.
To obtain a CDL in Washington, you must pass three written permit tests — General Knowledge, Combination Vehicles, and Air Brakes — at the Washington Department of Motor Vehicles. Similar to a regular driver's license permit exam, these are timed, multiple-choice tests based on the official Washington CDL handbook.
All of our practice material is built from the official Washington CDL handbook and federal resources, and curated by professionals with over 10 years of experience in the commercial transportation industry. Studying with practice tests that mirror the real exam format is one of the most effective ways to pass on your first try.
On this page you'll find free practice tests for all three sections. For the full question bank and additional study features, download the CDL Help app.
CDL Requirements in Washington

- Must not have a lifetime driver license disqualification.
- Must provide proof of U.S. citizenship or lawful permanent residency with approved documentation.
- Must self-certify the type of driving you will be doing (intrastate or interstate) and complete a DOT physical examination. The medical examiner uploads the certificate to the National Registry — if it is not uploaded, the DOL cannot issue your CDL.

- Must pass the knowledge test for the specific type of commercial vehicle you will operate.
- Must obtain a Commercial Learner's Permit (CLP) before proceeding to the skills test.
- Must complete the training requirements for the type of CDL sought. Entry Level Driver Training (ELDT) is required for first-time Class A or Class B CDL applicants, upgrades from Class B to Class A, and first-time Passenger (P), School Bus (S), or Hazmat (H) endorsements.
- Must hold a CLP for at least 14 days before taking the skills test.
- Must pass the CDL skills test (Pre-trip Inspection, Basic Vehicle Control, and On-road Driving).
- Hazardous Materials endorsement requires completion of a hazmat training course before taking the hazmat knowledge test, plus a TSA background check.
- CDL classes: Class A (combination vehicles 26,001+ lbs GCWR with towed vehicle over 10,000 lbs), Class B (single vehicle 26,001+ lbs GVWR), Class C (vehicles transporting 16+ passengers or hazmat under 26,001 lbs).
Official Washington CDL Handbook
The official Washington State Commercial Driver Guide covers every topic tested on the state's CDL knowledge exam — but its dense, reference-style format makes it difficult for self-study. A more effective preparation tool is our set of General Knowledge practice tests. Our free Washington CDL permit practice test is structured to closely match the format and content of the official exam and is fully updated as of February 2026. Each test includes 20 questions covering critical topics such as vehicle inspection, safe driving techniques, air brakes, cargo securement, driving emergencies, hazardous conditions, and Washington-specific commercial driving regulations. Unlike the official test, every practice question comes with a helpful hint and a detailed explanation of the correct answer — so you learn from every question, not just the ones you get right.
- Complete CDL regulations and Washington-specific requirements
- Safe driving techniques, vehicle inspection, and cargo handling
- All endorsement categories and testing requirements
Non-Domiciled CDL Information
Important information about non-domiciled commercial driver's licenses in Washington.
Federal regulations on non-domiciled CDLs are changing rapidly. The information below reflects the latest known state actions.
Washington's Department of Licensing (DOL) has stopped processing all non-domiciled Commercial Learner's Permit (CLP) and CDL transactions — including originals, renewals, upgrades, duplicates, and replacements — and has halted all knowledge and skills testing for non-domiciled drivers. The DOL website advises applicants to check back for updates on when processing will resume.
Under the FMCSA final rule published on February 13, 2026 (effective March 16, 2026), eligibility for non-domiciled CLPs and CDLs is now restricted to foreign-domiciled individuals holding specific, verifiable employment-based nonimmigrant statuses — specifically H-2A (agricultural workers), H-2B (non-agricultural workers), and E-2 (treaty investors) visa holders. Employment Authorization Documents (EADs) are no longer accepted as proof of eligibility, and State DMVs must use the federal SAVE database to confirm immigration status. This rule aligns the issuance of non-domiciled CDLs with FMCSA's statutory mandate to ensure the fitness of all CMV drivers, restoring the integrity of the CDL system and enhancing public safety.[FMCSA Final Rule]
English Language Proficiency (ELP)
Federal ELP enforcement applies to all CDL holders nationwide.
Federal ELP enforcement applies to all CDL holders nationwide. Here is how it is enforced in Washington.
Washington does not currently administer a separate state-level English Language Proficiency (ELP) test for CDL applicants. However, all Washington CDL holders are subject to federal ELP enforcement, which took effect on June 25, 2025. Under FMCSA guidance, all roadside inspections must begin in English, and if a driver appears unable to understand or respond appropriately, the officer proceeds with a formal two-step English Proficiency Assessment — a conversational interview in English (no interpreters, translation apps, or other language facilitation tools are permitted), followed by a test on reading and interpreting standard U.S. traffic signs. Drivers who fail either step face citation and immediate out-of-service status under CVSA North American Standard Out-of-Service Criteria.
