How to Activate SunPass?

SunPass is a digital toll payment program launched by Florida’s Department of Transportation in 1999. To facilitate toll payments with SunPass, motorists must sign up for a SunPass account, purchase a SunPass transponder of their choice, install the device in their car, and activate it.

SunPass is the most affordable and popular toll payment system in Florida, with a user base of more than 13 million motorists. Once you install and activate SunPass and approach a toll booth, the transponder transmits wireless signals to the booth and gives it the green light to debit the toll rates from your prepaid account.

There are various models of SunPass transponders – the SunPass Mini and the SunPass Pro. The coverage you want should determine the kind of SunPass transponder you go for. For instance, if you travel to several states by road, we recommend using the SunPass Pro.

At the same time, the SunPass Mini is better suited for motorists traveling within Florida or to Georgia and North Carolina. Activating the SunPass is a simple process. Keep reading to know how.
