The document outlines the requirements and regulations for obtaining and carrying a valid driver license in Missouri. It emphasizes that anyone operating a motor vehicle or motor-driven cycle on public roads in Missouri must have a valid Missouri driver license. This applies to residents aged 16 or older who plan to drive, new residents who want to drive regardless of having an out-of-state license, and commercial drivers who have recently moved to Missouri. Exceptions include active armed forces members, full-time students with valid licenses from their home states, and individuals operating farm equipment temporarily on highways.

The document also details the necessity to carry the license or permit while driving and the illegality of allowing others to use one’s license. It highlights the verification requirements for obtaining a new license or permit, including proof of lawful status, identity, social security number, and Missouri residency. For young drivers under 21, Missouri issues specific permits as part of its Graduated Driver License (GDL) program, starting with an instruction permit at age 15, which allows supervised driving. Additionally, motorcycle instruction permits are available for those aged 15½ or 16, enabling them to learn motorcycle operation under specific conditions. The document clarifies that test results alone do not serve as a permit or license and must be followed by an application at a license office to receive the official permit or license.
