PC Magazine reports that Visa has yet to respond to whether its cards may have fallen victim to hackers.
On Saturday, we learned MasterCard sent out warnings to banks to alert them to fraudulent charges showing up on credit cards.
The cards were used to make purchases through the DMV website from last August through January of this year.
The DMV says there's no evidence of a breach, but says an investigation is ongoing.
The agency says it will contact any drivers if needed.
