Starting in January of 2018, residents of several states will not be able to travel – even domestically – with just their driver’s licenses.

IDs from Kentucky, Maine, Minnesota, Missouri, Montana, Oklahoma, Pennsylvania, South Carolina and Washington do not meet federal minimum security standards, and since the TSA is a federal agency, they cannot accept IDs that do not meet those minimum standards.

To meet these standards, states must verify the ID applicant’s identity, put anti-counterfeit technology in the card and conduct background checks on issuers of driver’s licenses.

Residents of states that do not yet comply with these standards can still travel past 2018, but they must use alternate forms of ID such as a passport, military ID or permanent resident card.
