From the FAQ:
"DHS has been working with states for years around REAL ID compliance and have provided technical assistance, grants and other support to them. We are also providing more than two years advance notice of implementation with respect to domestic air travel to allow ample time for all states to achieve compliance, or for potential air travelers to acquire an alternate form of ID if their state does not comply with REAL ID.
Starting January 22, 2018, travelers who do not have a license from a compliant state or a state that has been granted an extension (...) will be asked to provide alternate acceptable identification. If the traveler cannot provide an acceptable form of identification, they will not be permitted through the security checkpoint.
Just an FYI.
