The Department of Homeland Security announced today that they are extending the Real ID requirement due to circumstances related to COVID-19. The date is now October 1, 2021.
This is important for travelers as TSA will not be able to use your non-Real ID drivers license as a form of ID to pass through security at airports.
If you aren't familiar with Real ID, it is a new secure drivers license DHS is requiring states to implement. In most states, it requires additional documentation when applying for a new drivers license or a renewal. More about Real ID from DHS.
