Oregon CDL practice test
The CDL general knowledge test follows federal standards, so these questions apply in Oregon just as they do nationwide — it is the same test that earns your OR commercial learner's permit (CLP). Below the test you'll find the Oregon-specific steps to actually get licensed.

Oregon endorsement tests
General knowledge is the test above. Each endorsement has its own written test and its own question pool — practise the ones your job needs, with the OR steps on each page.
Getting your CDL in Oregon
In Oregon, apply through the state licensing agency (OR DMV / DOT). The core steps are the same across states:
- Get a valid OR driver's license and provide required identity documents.
- Pass the DOT physical with a certified medical examiner and carry your medical card.
- Pass the written knowledge tests (general knowledge plus any endorsements you need).
- Hold your commercial learner's permit (CLP) for the required waiting period.
- Complete Entry-Level Driver Training (ELDT) with a registered provider, if required.
- Pass the skills test — pre-trip inspection, basic controls, and road test.
Exact fees, permit hold times, and document requirements are set by Oregon. Confirm the current details with the OR licensing agency before you go.
What is different in Oregon
Licensing in Oregon runs through the Oregon Driver & Motor Vehicle Services. The part that catches people out is not the test — it is the medical certificate, because the way it reaches the state changed in 2025.
Your medical examiner uploads the certificate information to the FMCSA National Registry, FMCSA transmits it electronically to the Oregon DMV, and the DMV records it on your driver record. You must have valid medical certificate information on your DMV record before the previous certificate information expires — and Oregon states plainly that you are responsible for knowing when your certificate will expire.
A missed upload can cost you the licence, and the DMV cannot fix it
Oregon tells examiners directly: the certificate must be uploaded to the FMCSA National Registry no later than midnight the day after the examination — if it is not, the DMV cannot process it, and the driver may lose their commercial driving privileges. There is no counter where a paper copy rescues a missed upload, so confirming the transmission happened is worth a phone call.
The Oregon DOT physical page has the rest — what the exam checks, what happens if your certification lapses, and the DMV contacts worth having.
