PORTLAND — Maine Turnpike officials are trying to get more people to use the turnpike’s electronic toll collection system.

The Maine Turnpike Authority says it’s reducing the price of the E-ZPass windshield transponders from $25 to $10 to promote use of E-ZPass.

The transponders are mounted on windshields and activate antennas that are overhead at toll plazas to automatically deduct toll amounts from prepaid accounts or record transactions for those with commuter E-ZPasses.
