If you fail
If you fail: Louisiana retake rules
You can retake a failed knowledge exam once the same day if time allows, so 2 attempts per day. OMV charges no retest fee, and there is no fee for the road skills test. It does not publish a wait after a second same-day knowledge failure, or a cap on total attempts. If you fail the road skills test, the examiner gives you a return date 1 to 30 days out, and you cannot retest before then.
- knowledge exam, first failure (initial attempt) - same-day retake permitted after failure number 1: you may retest the same day.
- Attempt limit: 2.
- Retest fee: the agency does not publish a per-attempt retest fee that we could confirm.
- CDL applicant who has not completed all knowledge and skills exams and issuance within 360 days of application has all exam scores expired, forfeits the $15.00 application fee, and must restart the application process.
Some retake details for Louisiana are not published by the agency (Agency does not publish: retake fee), so confirm them with OMV before you rely on them.
