Oregon DMV Test FAQ
How many questions are on the Oregon CDL permit test?
The OR DMV CDL knowledge test has 35 multiple-choice questions drawn from the official state handbook — covering road signs, traffic laws, right-of-way, and safe-driving procedures.
Where can I read the official Oregon driver handbook?
The OR DMV publishes the official manual on its website. We also mirror it, mobile-formatted, at /handbooks/or/cdl.
Should I go with my first instinct on the Oregon test?
Usually yes. Research on multiple-choice exams shows changing an answer helps only when you realize you misread the question — not when you simply feel uncertain. Read carefully once, commit, move on.
What's a passing score on the Oregon DMV knowledge test?
You need 28 out of 35 correct — 80% — to pass. The result is displayed immediately after you submit.
Do I need a DOT medical card before the Oregon CDL test?
Yes. FMCSA requires a valid DOT medical examiner's certificate before you can be issued a CDL — bring it to your appointment. You cannot take the CDL knowledge test without one on file.
If I'm under 18, does a parent need to be with me for the Oregon test?
A parent or guardian doesn't sit through the test with you, but under-18 applicants normally need a parent's signature on the application before OR DMV will schedule or administer the exam. Bring the signed form.
If I fail, can I retake the Oregon test the same day?
Typically no — most states enforce a waiting period between attempts. See the retake FAQ item above (if we have specific data for your state) or ask the office when they schedule your retake.
Where can I verify these Oregon test details on an official source?
OR DMV publishes the authoritative rules at https://www.oregon.gov/odot/dmv/pages/online_manual/testing.aspx. We refresh our numbers annually against that page — if you spot a discrepancy, the DMV site is the source of truth.
Can I use my phone during the Oregon DMV knowledge test?
No. All electronics are prohibited during the exam and most offices ask you to leave them in a locker. Use your phone to drill practice tests before you walk in.
Are there "all of the above" trick answers on the Oregon test?
Occasionally, but they're not tricks — they're used when multiple listed actions are all correct. If two answer choices look correct and "all of the above" is offered, that's usually the right pick.
