HB 857 -- Driver's License Sponsor: Koller This bill makes it clear that all categories of driver's licenses are issued for 6 years, except those for persons between the ages of 18 and 21 or 70 and older which will be for 3 years. Persons who hold a commercial driver's license must apply for a duplicate license when their name is changed and must notify the Director of the Department of Revenue of any address change. However, an address change will not require filing for a duplicated license.Copyright (c) Missouri House of Representatives
