SunPass primarily operates in Florida and is designed for use on toll roads, bridges, and tunnels within the state. However, SunPass has some interoperability agreements with other states that allow travelers to utilize their transponders on certain toll facilities outside of Florida. For instance, SunPass can often be used in parts of Georgia and North Carolina, where certain regional toll authorities accept SunPass for toll payments. It is important to note that acceptance may vary based on the specific toll facility and location. Therefore, it is advisable to review the most recent information available on the current SunPass website to confirm where SunPass can be used outside of Florida and to check for any specific requirements or limitations. This will ensure that you have the most accurate and up-to-date information before traveling.
