What you need to know before you start

Oregon issues a Commercial Driver's License (CDL) through the Department of Transportation, and the process takes several weeks from start to finish. You will need to pass a written knowledge test, a skills test behind the wheel, and a medical examination. Oregon recognizes CDLs from other states, but if you are getting your first CDL or upgrading from a regular driver's license, you must complete the full testing sequence in Oregon.

The timeline matters: the medical exam must be completed before you take either test, and you cannot schedule your skills test until you have passed the written test. Most people spend four to eight weeks on the entire process, depending on how quickly they can book appointments and how many attempts the skills test takes.

Key Takeaways

  • You must pass a Department of Transportation medical exam before taking any CDL test in Oregon.
  • The written knowledge test covers vehicle operation, cargo safety, and hazmat rules depending on which endorsements you need.
  • Oregon requires a behind-the-wheel skills test in an actual commercial vehicle, which you must schedule after passing the written test.
  • Your current Oregon driver's license converts to a CDL once you pass both tests; you do not receive a separate document.
  • If you hold a valid CDL from another state, Oregon will recognize it, but you must still obtain an Oregon CDL within 30 days of establishing residency.

Step 1: Get a Department of Transportation medical exam

Before you do anything else, you must have a medical examination performed by a FMCSA-certified medical examiner. FMCSA stands for Federal Motor Carrier Safety Administration, and only examiners on their national registry can sign off on your medical certificate. This is not your regular doctor — you need someone specifically listed in the FMCSA database.

You can find certified examiners through the FMCSA National Registry at fmcsa.dot.gov. Search by Oregon and your city to see who is available near you. The exam costs between $100 and $200 and covers vision, hearing, blood pressure, and a review of your medical history. The examiner will give you a medical certificate valid for two years (or one year if you have certain medical conditions). You must bring this certificate when you explore for your CDL.

Step 2: Prepare for and pass the written knowledge test

Oregon's CDL written test is administered at any DMV office and covers the rules of the road specific to commercial vehicles. The test has two parts: a general knowledge section that everyone takes, and endorsement-specific sections depending on which type of commercial vehicle you plan to drive. If you are pursuing a passenger endorsement, for example, you will answer questions about passenger safety. If you want hazmat, you will answer questions about hazardous materials transport.

You can study using the Oregon CDL Manual, available free on the Oregon Department of Transportation website. The general knowledge section has 50 questions; you must answer at least 40 correctly to pass. Endorsement tests are shorter, usually 20 to 30 questions with a similar passing threshold. You can take the test as many times as you need, but you must wait one day between attempts.

Schedule your written test at your local DMV office. Bring your medical certificate, your current Oregon driver's license, and proof of your Social Security number. The test costs $15 and takes about 45 minutes. Once you pass, you will receive a temporary permit that allows you to drive a commercial vehicle with a licensed CDL holder in the seat next to you — this is called operating under a permit.

Step 3: Schedule and pass the behind-the-wheel skills test

After you pass the written test, you can schedule your skills test. Oregon requires you to take this test in an actual commercial vehicle that matches the class of license you are seeking. You cannot use a simulator or a smaller truck — the vehicle must be the real thing and must be registered to either you, your employer, or a third-party testing service.

The skills test has three parts: a pre-trip inspection where you walk around the vehicle and point out safety features, a basic control test where you perform maneuvers like backing up and parking, and a road test where you drive on public roads for about 30 minutes. The entire test takes roughly two hours. You must score at least 80 percent to pass.

Contact the Oregon DMV to schedule your skills test appointment. Wait times vary by region but typically range from two to six weeks. You will need to bring your medical certificate, your current driver's license, your temporary permit from passing the written test, and proof of vehicle registration. The test costs $50. If you do not pass, you can retake it after waiting one day.

What happens after you pass both tests

Once you pass the skills test, your Oregon driver's license is automatically updated to a CDL. You do not receive a new physical card when ready — the change is recorded in the DMV system. Your next renewal notice will show your CDL status. If you need proof of your CDL before your renewal, you can request a duplicate license at any DMV office for $20.

Your CDL is valid for eight years in Oregon, the same as a regular driver's license. You must renew it by your birthday in the year it expires. If you move out of Oregon and establish residency in another state, you must obtain a CDL in that state within 30 days.

If you already hold a CDL from another state

Oregon recognizes valid CDLs issued by other states, so you can legally drive a commercial vehicle in Oregon on your current license. However, if you establish residency in Oregon — meaning you move here and intend to stay — you must obtain an Oregon CDL within 30 days. Residency is typically established when you register a vehicle in Oregon, get an Oregon voter registration, or enroll in an Oregon school.

To convert your out-of-state CDL to an Oregon CDL, you must pass Oregon's written knowledge test and skills test, just as if you were getting your first CDL. You do not need to retake the medical exam if your current medical certificate is still valid. Bring your out-of-state CDL, your medical certificate, and proof of Oregon residency to the DMV to begin the process.

Frequently Asked Questions

Can I use my regular Oregon driver's license to drive a commercial vehicle while I am waiting for my skills test?

No. Once you pass the written test, you receive a temporary permit that allows you to drive a commercial vehicle only if a licensed CDL holder is sitting next to you. You cannot drive commercially alone until you pass the skills test and your license is updated to a CDL.

What if I fail the skills test?

You can retake it after waiting one day. There is no limit to how many times you can attempt it. Each retake costs $50. Many people pass on their second or third attempt, so one failure does not mean you cannot get your CDL.

Do I need to take the written test again if I want to add a new endorsement later?

Yes. Each endorsement requires its own written test. You do not need to retake the general knowledge section, only the endorsement-specific test. You also do not need to retake the skills test unless you are upgrading to a higher class of vehicle.

How long is my medical certificate valid?

A medical certificate is valid for two years from the date the examiner signs it. If you have certain medical conditions, it may be valid for only one year. Your medical certificate must be current when you take your CDL tests and when you renew your license.

What if I move to another state after I get my Oregon CDL?

Your Oregon CDL remains valid in all other states. You do not need to convert it unless you establish residency in another state, at which point you have 30 days to obtain a CDL in that state.
