Aug. 4 primary election. To eliminate transportation barriers and ensure voter access, the tri-county region’s three transit agencies – CATA, EATRAN and Clinton Transit – are offering systemwide free rides. June 25 through Aug. 4 free transportation is available for tri-county residents to register to vote, return absentee ballots at drop boxes, participate in early voting and cast their ballot on Election Day. Just let the driver know you are going to register or vote when you board. No ID is required to receive a free ride.
