Residents of four states and one US territory will not be able to use their driver’s license to board even a domestic flight sometime in 2016 under a new federal law.

According to an article on nypost.com, driver’s licenses in New York, Louisiana, Minnesota and New Hampshire, as well as American Samoa, will not meet the standards dictated by the Real ID Act, passed by Congress in 2005.

The Department of Homeland Security has determined the licenses in those states lacked sufficient security features and another form of identification will have to be used when boarding a plane, such as a passport.

But don’t hit the panic button just yet.  Other forms of identification will be acceptable, like a government-issued passport.  Some states, such as New York, have been offering a Enhanced Driver’s License since 2008, which can also be used.  The enhanced license cost an extra $30, and requires the applicant to appear in person, provide proof of identity, Social Security number, residency, date of birth and citizenship.

The New York Department of Motor Vehicles (DMV) has asked Homeland Security for an extension in enforcing the act, which was enacted to provide extra security measures in the wake of the 9/11 attacks of terrorism.

The DMV issued a statement saying they had no reason to believe that any New Yorker will have a problem using their current driver’s license.

The Department of Homeland Security began using Real ID measures in 2014 at restricted and semi-restricted government areas and around nuclear power plants.  The final phase of the act covers federally regulated air traffic and is scheduled to take effect in 2016.

Military or government ID cards, passport cards and Homeland Security-accepted traveler cards, like NEXUS or Global Entry, would be acceptable for use under the act as well.
