Beginning on January 22nd, federal law will require Real ID compliance to fly domestically and to visit federal facilities. Kentucky has asked for an extension beyond the January deadline and it has been granted

Here is the official statement from the Kentucky Transportation Cabinet:

The new October 10th, 2018 deadline will give Kentucky Circuit Court Clerks' Offices enough time to get the equipment installed to issue the new enhanced driver's licenses.

There's a possibility Kentucky officials will ask for more extensions that will carry over into 2019.
