Florence Moka is in the Collin County jail for not paying more than $14,000 she owes in tolls to the North Texas Tollway Authority.
Moka was jailed on warrants Wednesday after she failed to show up in court in 2012 to explain why she didn't pay tolls dating back to 2010.
The NTTA has approximately $50 million in unpaid tolls.
We contacted the NTTA to see if any other violators were in jail due to non-payment of tolls, but so far, they haven't responded.
