What you need to know about Washington's CDL process
A Commercial Driver's License (CDL) in Washington is issued by the Department of Licensing and allows you to operate vehicles over 26,000 pounds, vehicles carrying hazardous materials, or buses carrying 16 or more people. The state requires you to pass a written knowledge test, a skills test, and a medical examination before you can drive commercially. Washington has three CDL classes—A, B, and C—based on the vehicle weight and cargo type, and you must hold a valid regular driver's license before you start the CDL process.
The entire process typically takes several weeks because you need to schedule tests through the Department of Licensing, and appointment availability varies by location. You will pay separate fees for the knowledge test, the skills test, and the medical certificate, and costs add up quickly if you need to retake any test. Understanding each step and what documents you need before you begin saves time and money.
Key Takeaways
- Washington requires a valid regular driver's license, a medical certificate from an approved examiner, and passing scores on both a written knowledge test and a behind-the-wheel skills test.
- The three CDL classes—A, B, and C—cover different vehicle weights and cargo types, and you must choose the correct class for the work you plan to do.
- You can add endorsements to your CDL (such as Hazmat or Passenger) by passing additional tests, which many commercial driving jobs require.
- The Department of Licensing handles all testing and licensing in Washington, and you schedule appointments directly through their office or online system.
- Retaking a failed test costs money and delays your license, so many drivers take a CDL training course before attempting the official tests.
Washington's three CDL classes and what each one covers
A Class A CDL allows you to drive any combination of vehicles with a gross vehicle weight rating (GVWR) of 26,001 pounds or more, as long as the towed vehicle weighs more than 10,000 pounds. This is the broadest license and covers tractor-trailers, doubles, and triples. Most long-haul trucking jobs require a Class A.
A Class B CDL covers single vehicles with a GVWR of 26,001 pounds or more, or any such vehicle towing a vehicle under 10,000 pounds. This includes dump trucks, cement mixers, and large buses. Class B drivers cannot tow heavy trailers, which limits the types of work available.
A Class C CDL is the most restricted and applies only to vehicles under 26,001 pounds that carry hazardous materials or 16 or more passengers. Most Class C work involves driving buses or small hazmat vehicles. You must choose the class that matches the vehicle you will actually operate, because driving a vehicle heavier than your license class permits is illegal and can result in fines and license suspension.
Medical certification and the FMCSA physical exam
Before you can take the CDL knowledge test, Washington requires a medical certificate issued by a certified Medical Examiner listed on the Federal Motor Carrier Safety Administration (FMCSA) National Registry. This is not your regular doctor's checkup—it is a specific exam that checks your vision, hearing, blood pressure, and ability to safely operate a commercial vehicle. The exam costs between $75 and $150 depending on the examiner, and you pay out of pocket.
The medical certificate is valid for two years, and you must have a current one in your possession when you take the knowledge test. If your certificate expires before you complete the CDL process, you will need to get a new one. You can find FMCSA-certified examiners through the FMCSA National Registry on their website, or ask the Department of Licensing for a list of examiners in your area.
Common reasons for failing the medical exam include uncontrolled high blood pressure, vision worse than 20/40 in each eye, or certain medical conditions that affect your ability to drive safely. If you fail, the examiner will tell you what needs to change before you can reapply, and some conditions can be managed with treatment or medication.
The knowledge test and what it covers
Washington's CDL knowledge test is a written exam administered by the Department of Licensing at their offices throughout the state. The test covers general commercial driving knowledge, vehicle inspection, safe driving practices, and hazard perception. You must score at least 80 percent to pass. The test takes about 60 to 90 minutes, and you can take it on a computer at most testing locations.
If you are pursuing endorsements—such as Hazmat (hazardous materials), Passenger (buses), or Tanker—you will take separate knowledge tests for each one. Each endorsement test covers specific rules and safety practices for that cargo or vehicle type. You can take endorsement tests on the same day as your general CDL test or schedule them separately.
The Department of Licensing provides a CDL Manual that covers all test material, and you can read it free from their website or pick up a printed copy at any licensing office. Many drivers study the manual on their own, while others take a CDL training course that covers the same material in a classroom or online setting. The knowledge test costs around $20 to $30, depending on how many endorsements you test for.
The skills test: pre-trip inspection, backing, and road driving
The skills test is a behind-the-wheel exam that takes place over one to two hours and covers three parts: the vehicle pre-trip inspection, the backing maneuver, and the road driving test. You must pass all three parts to pass the skills test overall. The Department of Licensing schedules skills tests at approved testing sites, and wait times for appointments can be several weeks depending on location and season.
During the pre-trip inspection, you walk around and under the vehicle while an examiner watches, pointing out and explaining the condition of brakes, tires, lights, mirrors, coupling devices, and safety equipment. You must demonstrate that you know what to check and why it matters for safe operation. This part tests your knowledge of vehicle systems, not just your ability to spot problems.
The backing maneuver requires you to back the vehicle into a tight space or around obstacles while staying within marked boundaries. This is often the hardest part for new drivers because it requires spatial awareness and precise control. You get one attempt, and hitting a cone or going outside the boundary is an automatic failure.
The road driving test takes place on public roads and includes turns, lane changes, merging, stopping, and acceleration. The examiner watches how you handle the vehicle, follow traffic laws, and respond to hazards. The skills test costs around $150 to $200, and if you fail any section, you must retake the entire test and pay the fee again.
CDL endorsements and when you need them
An endorsement is an additional qualification added to your CDL that allows you to operate certain types of vehicles or carry certain cargo. Washington recognizes several endorsements, each requiring a separate knowledge test and sometimes additional training or background checks.
The Hazmat (H) endorsement allows you to transport hazardous materials and requires passing a knowledge test plus a Transportation Security Administration (TSA) background check. The TSA check involves fingerprinting and a records review, and it costs around $85. Many trucking jobs require Hazmat because hazmat loads pay more but carry strict regulations.
The Passenger (P) endorsement is required to drive buses or any vehicle carrying 16 or more people. It requires a knowledge test and demonstrates your understanding of passenger safety, emergency procedures, and passenger management. School bus drivers and transit bus operators need this endorsement.
The Tanker (N) endorsement allows you to haul tanker vehicles carrying liquids or gases. It requires a knowledge test covering tanker-specific safety and handling. The Double/Triple (T) endorsement allows you to pull double or triple trailers and requires a knowledge test on coupling and uncoupling procedures.
You can add endorsements to your CDL at any time after you receive your license by passing the required tests and background checks. Many drivers add endorsements later as their career develops or as job opportunities arise.
How to schedule your tests with the Department of Licensing
Washington's Department of Licensing handles all CDL testing and licensing. You can schedule your knowledge test and skills test through their website, by phone, or in person at any licensing office. The website allows you to check available appointment times and book online, which is usually faster than calling or visiting in person.
You must bring your medical certificate, a valid form of identification, and proof of Washington residency to your knowledge test appointment. For the skills test, you also need to bring a vehicle that matches the class you are testing for—the Department of Licensing does not provide vehicles. Many people borrow a commercial vehicle from an employer or rent one from a commercial vehicle rental company.
If you fail a test, you can retake it, but you must wait at least one day before scheduling the next attempt. Retaking a test costs the same as the first attempt, so budget for the possibility of needing multiple tries. The Department of Licensing will mail your CDL to you within two weeks of passing all tests, or you can pick it up in person at a licensing office.
CDL training courses and whether they are worth the cost
Many people take a formal CDL training course before attempting the official tests. These courses range from four weeks to several months and cover classroom instruction, vehicle operation, and test preparation. Some courses are offered by community colleges, truck driving schools, or private training companies. Costs vary widely—from around $3,000 to $10,000 depending on the program length and location.
A training course is not required by Washington law, but it can increase your chances of passing the tests on the first attempt and may make you more attractive to employers. Some employers even sponsor training for new hires or reimburse training costs after a certain employment period. If you have no commercial driving experience, a course can teach you vehicle handling and safety practices that are hard to learn on your own.
If you choose to study on your own, the Department of Licensing's CDL Manual and practice tests are free resources. Many people pass the knowledge test by studying the manual for a few weeks. The skills test is harder to prepare for without hands-on practice, so some drivers take a short skills-focused course instead of a full program.
Frequently Asked Questions
Do I need a regular driver's license before I get a CDL?
Yes. Washington requires you to hold a valid regular driver's license before you can take the CDL knowledge test or skills test. Your regular license must not be suspended or revoked. If your regular license is expired, you must renew it first.
How long does it take to get a CDL in Washington?
The timeline depends on how quickly you can schedule tests and how many attempts you need. If you pass all tests on the first try and appointments are available, you could complete the process in four to six weeks. If you need to retake tests or wait for appointments, it can take two to three months or longer.
What happens if I fail the skills test?
You can retake the skills test after waiting at least one day. You must pay the test fee again and bring a vehicle that matches your license class. There is no limit on how many times you can retake it, but each attempt costs money and delays your license.
Can I add endorsements after I get my CDL?
Yes. You can add endorsements to your CDL at any time by passing the required knowledge tests and background checks. You do not need to retake the general CDL tests or the skills test to add an endorsement.
What disqualifies you from getting a CDL in Washington?
You cannot get a CDL if your regular driver's license is suspended or revoked, if you fail the medical exam, or if you have certain criminal convictions related to drugs or traffic violations. Some medical conditions also disqualify you, though some can be managed with treatment or medication.
