Washington CDL Practice Test 2026: Free Study Guide & Tests

You’re planning to get your Commercial Driver’s License in Washington State — and you couldn’t have picked a better place to do it. Washington is a freight powerhouse, home to the Ports of Seattle and Tacoma (the largest container ports in the Pacific Northwest), a booming aerospace industry led by Boeing, and a vast agricultural economy that produces more apples than any other state in the nation. Over 80,000 commercial truck drivers keep Washington’s economy moving, hauling freight along I-5 from the Oregon border all the way to Canada, across the Cascade Mountains on I-90, and through the fertile plains of Eastern Washington.

But before you can get behind the wheel of an 80,000-pound combination vehicle navigating Snoqualmie Pass in a snowstorm or threading through Seattle’s crowded freight corridors, you need to pass the Washington CDL exam. The Washington State Department of Licensing (DOL) administers the CDL program under federal FMCSA guidelines, and the process is designed to make sure only safe, qualified drivers hit the road.

This guide gives you everything you need to prepare for the Washington CDL test: exact test format, state-specific requirements, what makes Washington different from other states, and free practice tests covering every knowledge exam you’ll face.

Washington CDL Requirements: What You Need to Know

Washington follows the federal CDL standards established by the FMCSA under 49 CFR Part 383, with some state-specific requirements administered by the Washington State Department of Licensing (DOL). Here’s exactly what Washington requires:

Age Requirements in Washington

License TypeMinimum AgeRestrictions
Intrastate (Washington only)18 yearsCannot drive across state lines
Interstate (all states)21 yearsNo state-line restrictions
HazMat Endorsement21 yearsFederal requirement — no exceptions

Washington CDL Fees

Fee TypeAmountDetails
CLP Application$35Valid for 180 days
CDL Application/Processing$35One-time processing fee
CDL License Issuance$10/yearTypical 5-year term = ~$50
Endorsement Fees$5 eachPer endorsement added
Skills Test (Third-Party)$100–$250Varies by testing location
HazMat (TSA Background Check)~$86Federal TSA fee, separate from DOL

Unlike some states that handle CDL skills testing in-house, Washington delegates skills testing to approved third-party testers and training schools. This means your skills test fee will vary depending on which provider you choose. Knowledge testing is included in your application fee — no extra charge per knowledge test attempt.

Washington ELDT Requirements

Since February 7, 2022, all new CDL applicants in Washington must complete Entry-Level Driver Training (ELDT) through an FMCSA-approved training provider. This is a federal requirement — no state can waive it. The Washington DOL verifies ELDT completion electronically through the FMCSA Training Provider Registry (TPR).

ELDT is required for:

  • Original Class A or Class B CDL
  • Upgrading from Class B to Class A
  • First-time School Bus (S), Passenger (P), or HazMat (H) endorsements

You must hold your Commercial Learner’s Permit (CLP) for at least 14 days before taking the skills test. Your CLP is valid for 180 days (6 months) in Washington — giving you plenty of time to practice and prepare.


Washington CDL Test Format: What to Expect

The Washington CDL exam has two parts: knowledge tests (written) and a skills test (driving). The knowledge tests are computer-based, multiple-choice, and administered at Washington DOL offices or approved testing facilities. All tests follow FMCSA content standards from the Washington CDL Driver Guide.

Knowledge Tests Overview

TestQuestionsPass ScoreRequired For
General Knowledge5080% (40 correct)All CDL classes
Air Brakes2580% (20 correct)Class A & B (if vehicle has air brakes)
Combination Vehicles2080% (16 correct)Class A
HazMat (H)3080% (24 correct)HazMat endorsement
Tanker (N)2080% (16 correct)Tanker endorsement
Passenger (P)2080% (16 correct)Passenger endorsement
School Bus (S)2080% (16 correct)School bus endorsement
Doubles/Triples (T)2080% (16 correct)Double/triple trailers

All Washington CDL knowledge tests follow FMCSA content standards. The passing score is 80% on every test — no exceptions. The knowledge tests cover the same material you’ll find in the Washington CDL Driver Guide published by the DOL.

Washington Skills Test: Three Parts

The Washington CDL skills test is administered by DOL-approved third-party testers and training schools — not directly at most DOL offices. You must provide your own vehicle for the test, and it must be the same class of vehicle you’re applying for.

SectionWhat It TestsDetails
1. Pre-Trip InspectionVehicle safety knowledgeVerbally identify and explain critical components: engine, brakes, tires, lights, coupling systems
2. Basic Vehicle ControlBacking and maneuveringStraight-line backing, offset backing, parallel parking, alley dock
3. On-Road DrivingReal-world drivingLane changes, turns, braking, gear usage, speed management, traffic law compliance

Washington skills test retake policy: If you fail the skills test, you must wait 14 days before retaking it. Full test fees apply for each retake, and policies may vary slightly depending on your third-party tester. For knowledge tests, you can retake the exam the next business day.


What Makes Washington CDL Different from Other States?

The core CDL exam is federally standardized — the General Knowledge, Air Brakes, and endorsement tests cover the same material in every state. But Washington has unique geographic, economic, and weather characteristics that make commercial driving here unlike anywhere else:

Washington-Specific Driving Conditions

  • Cascade Mountain crossings: Snoqualmie Pass (I-90, 3,022 ft) and Stevens Pass (US-2) feature steep grades, tight curves, and mandatory chain requirements from November through April. Drivers must know chain installation, downhill braking techniques, and how to read mountain weather forecasts.
  • Relentless rain: Western Washington gets 35–45 inches of rain annually. Hydroplaning, reduced visibility, and flooding are daily realities on Puget Sound-area routes from November through April. The General Knowledge test emphasizes speed reduction and following distance — critical in wet conditions.
  • Puget Sound fog: Dense morning fog blankets the I-5 corridor and coastal highways, especially during fall and winter months. Visibility can drop to under 100 feet in minutes.
  • Columbia River Gorge winds: High-profile vehicles face dangerous crosswinds through the Gorge, a major freight corridor connecting the Portland-Vancouver metro area to Eastern Washington.
  • Eastern Washington ice: The Columbia Basin and Palouse region experience freezing rain, black ice, and blizzard conditions from December through February. Roads like I-82 and US-2 can become treacherous with little warning.
  • Wildfire smoke: Eastern and Central Washington increasingly face summer and fall wildfire smoke that can reduce visibility to near-zero on major freight routes, creating hazardous driving conditions.
  • Washington State Ferries: The largest ferry system in the US serves Puget Sound routes with specific commercial vehicle restrictions, fees, and loading procedures. CDL drivers running routes to the Kitsap Peninsula, Whidbey Island, or the San Juans need to know ferry protocols.
  • Major port operations: The Ports of Seattle and Tacoma form the fourth-largest container gateway in North America. Drayage and intermodal drivers navigate congested terminal roads, tight appointment windows, and complex container-handling procedures.

While the CDL knowledge test itself won’t ask you Washington-specific geography questions beyond what’s in the standard handbook, understanding these conditions will make you a safer driver and help you contextualize the safety rules you’re learning. When the Air Brakes test asks about controlling a vehicle on a long downgrade, think about Snoqualmie Pass. When the General Knowledge test covers driving in fog, think about a November morning on I-5 near Tacoma.

Washington CDL Frequently Asked Questions

How many questions are on the Washington CDL General Knowledge test?

The Washington CDL General Knowledge test has 50 multiple-choice questions. You need to answer at least 40 correctly (80%) to pass. The test covers vehicle inspection, safe driving practices, cargo management, CDL regulations, and more — all based on the federal FMCSA standards that Washington DOL follows.

How much does a Washington CDL cost?

The total cost includes a $35 CLP application fee, a $35 CDL processing fee, and approximately $50 for the license itself ($10/year × 5 years). Endorsements cost $5 each. Your skills test through a third-party tester runs $100–$250. Additional costs include your DOT medical exam (typically $75–$150), TSA background check for HazMat (~$86), and ELDT training program tuition ($3,000–$8,000 if attending a school).

What happens if I fail a Washington CDL knowledge test?

If you fail a knowledge test in Washington, you can retake it the next business day. There’s no extended waiting period for knowledge test retakes. However, full application fees may apply for each retake depending on DOL policies. We strongly recommend using our practice tests until you consistently score above 80% before attempting the real exam to save time and money.

Can I get a Washington CDL at 18?

Yes. Washington allows you to get a CDL at 18 for intrastate driving only (within Washington State). You cannot cross state lines until you turn 21. The HazMat endorsement requires you to be at least 21, regardless of your license type. This means an 18-year-old can haul apples from Wenatchee to Seattle, but cannot legally drive that same load into Oregon.

Where do I take the Washington CDL skills test?

Washington CDL skills tests are administered by DOL-approved third-party testers and training schools, not directly at most DOL offices. You can find approved testers through the Washington DOL CDL Training and Testing page. You must provide your own vehicle for the test — it must match the class of license you’re applying for.

Do I need chains for mountain passes in Washington?

Yes. Washington law requires all vehicles over 10,000 lbs to carry tire chains from November 1 through April 1 on designated mountain routes, including Snoqualmie Pass (I-90), Stevens Pass (US-2), and other Cascade crossings. This applies to commercial vehicles regardless of weather conditions on a given day. Failure to carry chains can result in fines and being turned back at checkpoint stations. The DOL and WSDOT may also implement “chains required” status during severe weather, meaning chains must be installed.

Is the Washington CDL test the same as other states?

The knowledge tests are based on the same FMCSA standards and cover the same material as in every other state. Washington DOL uses the Washington CDL Driver Guide, which follows the federal CDL manual closely. Questions about vehicle inspection, safe driving, cargo securement, and endorsements are standardized nationally. Your Washington CDL is valid in all 50 states.

How long is a Washington CLP valid?

Your Commercial Learner’s Permit (CLP) in Washington is valid for 180 days (6 months) from the date of issuance. If you don’t complete your skills test within that window, you’ll need to reapply and pay the application fee again. However, 180 days gives you ample time to complete your behind-the-wheel practice and schedule your skills test.
