Governor Mary Fallin has officially asked the U.S. Department of Homeland Security to expand the state's REAL ID extension until October 10, 2019. The current extension expires on October 10, 2018. It allows Oklahomans to use their driver's license to gain entry into federal buildings and military installations and to board commercial aircraft. Fallin says Oklahoma and the Department of Public Safety are working with a vendor to develop a system to make Oklahoma driver's licenses REAL ID compliant but that won't be complete until April 2020. Congress passed the REAL ID Act in 2005 to make driver's licenses harder to forge.
