The basic path to a Washington CDL

To get a Commercial Driver's License (CDL) in Washington State, you must pass a written knowledge test, a skills test behind the wheel, and a Department of Licensing medical exam. You start by getting a CDL permit, then schedule your driving test at a third-party examiner location. The whole process typically takes four to eight weeks, depending on how quickly you book your test and how many attempts you need.

Washington does not require formal truck driving school, but many people attend one because it improves test pass rates and some employers will only hire drivers who completed a program. If you go the school route, expect to spend two to six weeks in class and behind-the-wheel training before you test.

You must be at least 18 years old to drive a commercial vehicle within Washington State, and 21 to drive across state lines. You also need a valid Washington driver's license before you can get a CDL permit.

Key Takeaways

  • You need a valid Washington driver's license, a medical certificate from a Department of Transportation-certified doctor, and proof of Washington residency before you can get a CDL permit.
  • The written test covers vehicle inspection, safe driving practices, and cargo handling; you can study using the official Washington CDL manual or third-party prep materials.
  • The driving test is administered by third-party examiners at locations across the state, not by the Department of Licensing itself, and you must bring your own vehicle or rent one that meets test requirements.
  • Attending a truck driving school is optional but increases your chances of passing the skills test on your first attempt and may be required by your future employer.
  • Washington recognizes CDL permits from other states, so if you already have one, you can transfer it by passing the written test and paying the transfer fee.

Getting your medical certificate and CDL permit

Before you can take any test, you must see a Department of Transportation (DOT) medical examiner and get a medical certificate. This is not your regular doctor — it must be someone on the National Registry of Certified Medical Examiners. You can find approved examiners on the Federal Motor Carrier Safety Administration website or by calling your local Department of Licensing office. The exam checks your vision, hearing, blood pressure, and ability to operate a vehicle safely. It costs between $100 and $200 and is valid for two years.

Once you have your medical certificate, go to your local Department of Licensing office with your valid Washington driver's license, proof of residency (utility bill, lease, or bank statement), and the medical certificate. Pay the CDL permit fee (currently $35) and pass the written knowledge test on the same day. If you fail the written test, you can retake it the next business day.

Your CDL permit is valid for 180 days. During this time, you can practice driving a commercial vehicle with a licensed CDL holder in the passenger seat, but you cannot drive commercially for pay. If you do not pass your skills test within 180 days, your permit expires and you must reapply.

Studying for and taking the written test

The written test has 50 questions covering vehicle inspection, safe driving, braking systems, cargo handling, and hazardous materials (if you want a hazmat endorsement). You must score at least 80 percent to pass. The test is given on a computer at your Department of Licensing office and takes about 30 minutes.

Washington publishes the official CDL manual free on its Department of Licensing website. It covers everything the test asks about. Many people also use third-party study apps and practice tests, which can help you identify weak areas. Some truck driving schools include test prep in their tuition. You do not need to attend school to pass the written test — studying the manual on your own is enough for most people.

The test is offered in English only. If you need an interpreter, contact your local Department of Licensing office at least two weeks before your test date.

Scheduling and passing the skills test

After you pass the written test and get your CDL permit, you schedule your skills test with a third-party examiner. Washington contracts with private testing companies to administer the driving test; the Department of Licensing does not do it. You can find examiners and book a test slot on the Department of Licensing website or by calling the office. Wait times vary by location — some areas have openings within two weeks, others may take six weeks or longer.

The skills test has three parts: a pre-trip vehicle inspection (you walk around the truck and point out safety features), a basic control test (backing, turning, and parking in a lot), and a road test (driving on public roads for about 30 minutes). You must bring a vehicle that meets test requirements — it must be a commercial truck or combination vehicle with air brakes, and it must be insured and registered. If you do not own a truck, many truck driving schools rent vehicles for the test, usually for $50 to $150.

You must pass all three parts on the same day to pass the test. If you fail one part, you can retake the entire test, but you must schedule a new appointment and pay the test fee again (usually $100 to $150). Most people pass on their second or third attempt.

Truck driving school: when it makes sense

Attending a truck driving school is not required by Washington law, but many employers will only hire drivers who completed a program. Schools typically run four to six weeks and cost $3,000 to $7,000. They teach vehicle operation, safety, logbook rules, and often include test prep and a vehicle for your skills test.

If you have no commercial driving experience, school significantly improves your odds of passing the skills test on your first attempt. Schools also provide job placement help — many have relationships with trucking companies and can connect you to employers. If you are paying for school yourself, ask whether the school guarantees job placement or offers a refund if you do not find work within a set time.

Washington does not have a state-run truck driving school, but private schools operate throughout the state. Check that any school you consider is accredited by the Professional Truck Driver Institute or listed on the Department of Licensing website.

Endorsements and restrictions

Your basic CDL allows you to drive most commercial vehicles. You can add endorsements to haul hazardous materials (H), transport passengers (P), or operate double or triple trailers (T). Each endorsement requires passing an additional written test. You take these tests at the Department of Licensing office on the same day as your main CDL test or later, depending on your schedule.

Some jobs require specific endorsements — for example, fuel tanker driving requires the H endorsement, and school bus driving requires the P endorsement. If you know which type of work you want, ask your future employer which endorsements they need and study for those tests before you schedule your appointment.

Washington also issues restrictions based on your test results. If you pass the skills test in an automatic transmission truck, your license will be restricted to automatic only. If you pass in a vehicle without air brakes, you cannot drive air brake vehicles. You can remove these restrictions by retaking the skills test in a vehicle without the restriction.

Transferring a CDL from another state

If you already have a valid CDL from another state, you can transfer it to Washington without retaking the skills test. You must pass the Washington written test, get a DOT medical certificate, and pay the transfer fee (currently $35). Go to your local Department of Licensing office with your out-of-state CDL, proof of Washington residency, and your medical certificate. You will take the written test the same day.

Your out-of-state CDL remains valid while you are waiting for your Washington license to arrive. The transfer process usually takes two to four weeks. If your out-of-state CDL has endorsements, those transfer to your Washington license automatically if you pass the written test.

Frequently Asked Questions

How much does it cost to get a CDL in Washington?

The CDL permit costs $35, the written test is included with the permit, and the skills test costs $100 to $150 depending on the examiner. The medical exam costs $100 to $200. If you attend truck driving school, add $3,000 to $7,000. If you do not attend school and already own a commercial vehicle, your total out-of-pocket cost is roughly $250 to $400.

Can I take the written test online or at home?

No. The written test must be taken at a Department of Licensing office on a computer provided by the office. You cannot take it remotely or on your own device. You must go in person with a valid ID.

What happens if I fail the skills test?

You can retake it as many times as you need, but you must schedule a new test appointment and pay the test fee each time. Your CDL permit is valid for 180 days, so you have that window to pass. If your permit expires, you must reapply for a new one and retake the written test.

Do I need a CDL to drive a pickup truck with a commercial license plate?

No. You need a CDL only if the vehicle's Gross Vehicle Weight Rating (GVWR) is over 26,001 pounds, or if you are transporting hazardous materials or passengers for pay. Many commercial pickup trucks fall below that threshold and do not require a CDL. Check your vehicle's registration or owner's manual for the GVWR.

Can I get a CDL if I have a DUI or traffic violations?

A DUI does not automatically disqualify you, but it may affect your ability to get hired by trucking companies. Traffic violations do not prevent you from getting a CDL, but serious violations (reckless driving, at-fault accidents) can make you ineligible for certain endorsements or jobs. Contact the Department of Licensing if you have questions about your specific record.
