The Frequent Driver Rewards Program is MDX's customer rewards program that makes it possible to give back any savings from the efficient operations of the agency directly to MDX commuters, frequent users and businesses, after meeting its financial obligations. The way the program works is simple. Each fiscal year (July 1st to June 30th) MDX will declare a cash back distribution to members of the Frequent Driver Rewards Program which have qualified. The cash back is not guaranteed and it may vary every year based on savings of the operations of MDX.

  • How do I qualify for the Frequent Driver Rewards Program?

    The criteria for the program requires MDX customers to register their vehicle (two-axles), be a SunPass® customer in good standing, and spend at least $100 annually between July 1st to June 30th in tolls for the use of any of MDX's five expressways. Any tolls paid using Toll-By-Plate or Image Toll transactions (IToll) will be considered ineligible for the annual calculation. Eligibility of SunPass® tolls paid during the fiscal year will solely be determined by MDX.

    MDX Expressways are: SR 836/Dolphin Expressway, SR 112/Airport Expressway, SR 874/Don Shula Expressway, SR 878/Snapper Creek Expressway and SR 924/Gratigny Parkway.
