¹In Colorado, the minimum permit age varies. Fifteen year-olds who are enrolled in driver education may apply for an instruction permit. Their supervising driver must be a parent, stepparent, grandparent, guardian, or driving instructor. A person age 15, 6 months may apply for an instruction permit which allows driving while supervised by a parent, stepparent, grandparent, or guardian. Although driver education is not required at this age, applicants for this permit must have completed a 4-hour driver awareness program. At 16, young drivers may apply for a permit that allows driving while supervised by a licensed driver age 21 or older.
