Chapter 1: Your License to Drive

Understanding the types of driver licenses, the rules for obtaining one, and the responsibilities that come with it is the foundation of safe driving. This knowledge is essential for passing the written exam, as questions about the Graduated Driver License program, the point system, and required documents are common. More importantly, following these rules protects a driver’s privilege and ensures safety for everyone on the road.

In Missouri, anyone who operates a motor vehicle or motor-driven cycle on public roadways must have a valid driver license for that class of vehicle. The license must be carried at all times when driving and presented to any law enforcement officer upon request. It is illegal to allow another person to use one’s driver license or permit.

License Classes

Missouri issues several classes of licenses, each authorizing the operation of a different type of vehicle. For non-commercial purposes, the primary classes are F, E, and M.

• Class F License: This is the standard operator license for most drivers. It permits the holder to drive any non-commercial motor vehicle, including passenger cars, pickup trucks, and vans. A Class F license does not permit the operation of a motorcycle unless a specific endorsement is added. The minimum age to obtain a full Class F license is 18.
• Class E License (For-Hire): This license is required for individuals who drive for employment purposes under specific conditions. This includes operating a vehicle to transport 14 or fewer passengers for pay, such as for a daycare center, or transporting property for a job, like a delivery driver. It also applies to those who regularly operate a vehicle owned by someone else for work, carrying freight, with a gross vehicle weight rating of 26,000 pounds or less. The minimum age for a Class E license is 18.
• Class M License: This license is required to operate a motorcycle or motortricycle on public roads. An applicant can obtain a Class M license or add a Motorcycle (M) endorsement to their existing Class F or E license. This requires passing written, vision, road sign, and motorcycle skills tests.
