If you fail
If you fail: Oklahoma retake rules
You can retake the written test the next day, as many times as you need, but only 2 attempts are allowed online: after 2 online failures you must test in person at a Service Oklahoma location. No wait is published between in-person written attempts. Each failed written or drive test adds a $4.00 fee to the $42.50 issuance fee, payable when your credential is issued. The drive test can be retaken up to 3 times at least 1 day apart; after a third failure you wait 30 days, and every attempt after that is once per 30 days. No CDL retake wait, cap, or fee is published.
- Attempt limit: 2.
- Retest fee: $4 per attempt.
- Loss of the online testing channel: after two failed online written attempts, all further attempts must be made in person at a Service Oklahoma licensing office.
- Drive-test waiting period lengthens from 1 day to 30 days, and every subsequent attempt is limited to once per 30 days.

Study material
Languages and handbook
Our record of exam languages for Oklahoma: English and Spanish. This list is flagged for verification because the agency does not clearly say which languages the exam itself is given in (a handbook can be published in more languages than the exam), so confirm with Service Oklahoma before you rely on it.
The study source is the Oklahoma Driver Manual (2024-2025 edition).
