The Jacksonville Transportation Authority has suspended four bus drivers after finding out they did not have valid driver’s licenses.

JTA spokesman John Finotti said Thursday the authority has been doing driver’s license checks of their employees this week in reaction to a Times-Union investigation into the criminal and driving records o.... Those checks revealed four drivers with suspended licenses.

Finotti said he did not have their names but that they are expected to be released today.

The JTA does not have a policy for how to deal with this issue, Finotti said, but is working to come up with one now.

The drivers will not be allowed to drive a bus until their licenses are valid, he said. But it’s unclear if they will be paid while suspended or whether they will face any punishment beyond their suspension.

The Times-Union has been investigating the backgrounds of JTA bus drivers for months. The results of this investigation is scheduled to be published in Sunday’s Times-Union. Some of those issues occurred while the drivers were at the agency.
