Anyone who operates a motor vehicle or motor-driven cycle on public roadways in Missouri is required to have a valid driver license or learner's permit. The driver examination consists of a four-part test: a written test, a vision test, a road sign test, and a driving test. The questions on the written knowledge test will be based on information taken from the Missouri Driver's Manual.
