What is the minimum age for obtaining a full, unrestricted Missouri driver's license?

The minimum age for obtaining a full, unrestricted Missouri driver's license is indeed 18 years old. In Missouri, individuals can apply for a full license upon turning 18 after having held an intermediate license for at least six months. This progression is designed to ensure that new drivers gain experience in a structured manner, as teens often start with a learner's permit at 15, then move to an intermediate license at 16, which comes with certain restrictions to promote safe driving practices.

Thus, the age of 18 marks the stage at which a driver can transition to having full driving privileges without the limitations placed on younger drivers. Other ages—such as 16 or 17—reflect the age at which a learner's permit or intermediate license can be obtained, but do not qualify for the full, unrestricted license status outlined in the question.
