The REAL ID Act, passed in 2005, established a set of federal security standards for state driver's licenses that require specific information and machine-readable technology in form of a chip, according to SmarterTravel.
Travelers using IDs issued by certain states could be turned away at the gate beginning Jan. 30, 2017, if their state doesn't adjust to the new standards in time, WTSP reported. Some states are under review and have been given a deadline extension, but all licenses must comply with the standards by 2020, WTSP reported.
So far, 23 states and the District of Columbia are under compliance. Fourteen states have had their deadlines extended to Oct. 10, 2017, and four states were granted a limited extension through June 6, 2017. Five states are not in compliance, and one state — Montana — is under review. Three states did not receive an extension.
