SunPass is Florida’s Prepaid Toll Program and the preferred method of payment for tolls. Since many toll roads in Florida are converting to all-electronic, no cash tolling, it makes sense to get a SunPass. You can save an average of 25% on your tolls, plus, driving Florida’s toll roads with a SunPass transponder means no hassle no matter what toll road you drive. Opening a SunPass account requires the purchase, activation and installation of a transponder as well as having a prepaid balance on your account to keep it active. The two most commonly used SunPass transponders are the SunPass Mini and the SunPass PRO. Both devices that are placed on your vehicle’s windshield, just below the rearview mirror. As your vehicle passes through SunPass-equipped lanes, the toll charges are electronically deducted from your prepaid toll account.
