Tennessee driver’s license facilities and county clerk offices are unable to issue licenses this afternoon due to nationwide technology problems.

The American Association of Motor Vehicle Administrators confirmed its network, used by motor vehicle agencies across the U.S., experienced an outage beginning at 1:30 p.m. Eastern time and continuing intermittently.

“AAMVA is actively working to restore stable connectivity and will conduct a full analysis to determine the root cause of the outage,” according to the statement.

No estimated time was given for the system to be back up and running.

This is the fourth outage to affect Tennessee license facilities since October. The last national outage tied to the American Administration of Motor Vehicle Administrators occurred in January.

The outage has prevented most states from issuing or renewing driver’s licenses or issuing titles.

The outage was due to “a failure at the both the primary and secondary network locations," according to the AAMVA statement.
