If you fail
If you fail: Oregon retake rules
Each knowledge test attempt costs $7 for Class C and the motorcycle endorsement, or $10 for CDL. If you fail, you can retest the same day at a DMV office, depending on office capacity. Oregon publishes no limit on in-office attempts, but online testing is capped: no more than 2 attempts in any 24-hour period, and only 4 online attempts per test type, after which you must test at a DMV office.
- in_person_knowledge_test after failure number 1: you may retest the same day.
- online_knowledge_test after failure number 1: you may retest the same day.
- Attempt limit: 4.
- Retest fee: $7 per attempt.
- Online knowledge testing is locked out for the remainder of the 24-hour period; a third attempt must wait for the window to clear or be taken in a DMV office.
- Online testing is no longer available for that knowledge-test type; all further attempts must be made in person at a DMV office.
