If you fail
If you fail: Missouri retake rules
Missouri charges no fee for any written or skills test, so retests are free. You can retake a failed written test the same day, up to 2 attempts per day, until you pass. Skills tests are limited to 1 per day and to 3 tests in any 12-month period; after 3 failed skills tests the Highway Patrol cannot give you a fourth until the Director of Revenue approves further testing.
- written/knowledge test (all classes, including CDL knowledge tests) after failure number 1: you may retest the same day.
- driving skills test (all classes, including CDL and motorcycle skills tests) after failure number 1: wait 1 day.
- Attempt limit: 3.
- Retest fee: $0 per attempt.
- A fourth skills test is barred until the Director of Revenue approves the applicant for further testing (special permission from the DOR).

Study material
Languages and handbook
Our record of exam languages for Missouri: English, Spanish, Chinese, French, German, Greek, Italian, Korean, Russian, Vietnamese, Japanese, and Bosnian. 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 DOR before you rely on it.
The study source is the Missouri Driver Guide (2024-2025 edition).
