If you fail
If you fail: Wisconsin retake rules
A failed knowledge test can be retaken no sooner than the next calendar day, not the next business day. The in-person test at a DMV Customer Service Center is free; the $10 per-test fee applies only to the online KnowTo Drive Class D test, which allows 2 online attempts. The same test may be taken only 5 times within a one-year period, after which you need special permission from DMV staff.
- knowledge test (and CDL pre-trip inspection test), all license classes: wait 1 day.
- CDL skills test failed solely because the applicant failed both the straight-line and curved-path backing tests (CDL): wait 7 days.
- Attempt limit: 5.
- Retest fee: the agency does not publish a per-attempt retest fee that we could confirm.
- Must request and receive special permission from the department (DMV staff) before any further attempt at the same test.
- After two failed ONLINE Class D knowledge test attempts, the applicant loses the online channel and is forced to take the test in person at a DMV service center.
Some retake details for Wisconsin are not published by the agency (Agency does not publish: retake fee), so confirm them with DMV before you rely on them.
