How many questions are on the Missouri permit test?
Twenty-five multiple-choice questions, and you need 20 right. The written test is one of four parts given by the Missouri State Highway Patrol, along with a vision test, a road sign test and, later, the driving test.
The test is closed book and skips the commercial-vehicle chapter. The Department of Revenue says nearly half of first-time takers fail, and that every question comes straight from the Missouri Driver Guide.
