The Oregon Class C knowledge test costs $7 per attempt. This page explains what happens to that fee after a failed attempt and when another payment is required.
Oregon charges separate fees at different stages of the licensing process. A failed knowledge test means another $7 test fee is required for the next attempt; the $30 permit issuance fee is not collected merely because the applicant attempted and failed the test.
| Charge | Amount | When Charged |
|---|---|---|
| Class C Knowledge Test | $7 | Each attempt, online or at DMV |
| Standard Instruction Permit | $30 | When the permit is issued |
No. The $30 permit issuance fee is paid when DMV issues the permit. A failed knowledge-test attempt still costs $7, and another attempt requires another $7 test fee.
Yes. The Class C knowledge-test fee is $7 per attempt whether the test is taken online or at a DMV office.
Failed knowledge-test attempts require another test fee for another attempt. If a billing or technical problem occurs, follow Oregon DMV's current transaction-support process for that specific issue.
Third-party road-test cancellation and refund policies are set by those providers and are outside the primary intent of this knowledge-test refund page.
Oregon uses an electronic application rather than the old paper Form 735-173.
Every new knowledge-test attempt requires another $7 test fee. Whether you are eligible to retest the same day, how many online attempts are allowed, and other retake timing rules are covered on the dedicated Failed Knowledge Test page.
Yes. A permitted same-day retake requires another $7 test fee.
The online Class C knowledge test uses the same $7-per-attempt fee as an in-office test. This page focuses on what happens to the fee after an attempt; online attempt limits, device requirements, and testing format belong on their dedicated pages.
The simplest way to avoid extra test fees is to prepare before paying for another attempt. Use the current Oregon Driver Manual and official practice test, then retake when you are ready. Detailed study strategy belongs on the Practice Tests page.
For the permit transaction itself, use Oregon's electronic application and bring the required identity and residency documents to DMV.
"The AI mock tests were surprisingly realistic. The explanations for road signs helped me understand the logic, not just memorize. Passed my permit test on the first try!"

"I was struggling with the specific road rules of my state until I used Shoro. The flashcards are a game changer for quick revision before the actual exam."

"The readiness score gives you so much confidence. I knew exactly when I was ready to take the test. Highly recommend Shoro for anyone nervous about their exam."
