How many questions are on the Missouri permit test?
The Missouri permit knowledge test typically has 25 to 50 questions depending on the office and the version delivered on the day. To pass you need approximately 80% — that is usually 20 of 25, 32 of 40, or 40 of 50 correct. The test is delivered on a touchscreen at the MO DOR, and you generally cannot go back and change earlier answers once you advance past them.
How much does the permit cost in Missouri?
The current Missouri learner's permit fee is $3.50, payable at the counter by card, cash, or check (some Missouri branches are card-only). If you fail the knowledge test you may be required to pay a re-test fee for each subsequent attempt; check the current fee schedule on the MO DOR website before your appointment.

How long do I have to hold the permit?
In Missouri the supervised hold period is 12 months. During that time you must drive with a licensed adult age 21 or older in the front passenger seat. Many Missouri counties also require 50 logged hours of supervised driving, with at least 10 of them after sunset, before you become eligible for the road test.
Can I take the test in another language?
The Missouri permit test is offered in English and Spanish at every MO DOR office, and additional languages — typically Mandarin, Vietnamese, Korean, Tagalog, Russian, Armenian, and Punjabi — are available at major county offices and on most online versions. An interpreter you bring yourself is generally not allowed for the knowledge test.
What if I fail?
Most Missouri counties allow you to retake the test the same day or the next business day. After three consecutive failures you may be required to wait a longer period and pay an additional fee. The MO DOR will tell you which sections you missed; spend extra time in those sections of the handbook before returning.
