Oklahoma began issuing a new form of driver's license in 2012, but the state deliberately ignored new federal standards for licenses passed by Congress in 2005 under the "REAL ID Act."
The state didn't like the fact that it would have to ensure driver's license facilities were secure, and that issuers would have to be trained to spot fake documents.
There were also concerns expressed about privacy, and federal overreach.
Fast forward to 2015; in January, Oklahomans will no longer be able to enter secured federal buildings with a state-issued driver's license.
So in 2007 Oklahoma passed a law directing the Department of Public Safety to not comply with the REAL ID Act.
And beginning as early as 2016, they won't be able to board any federally-regulated aircraft with one, either.
Oklahomans, and residents of six other states who have failed to comply with REAL ID, will have to obtain another form of identification, such as a U.S. passport.
