Please note that while just two (2) people are required in the vehicle on HOV lanes north of Glades Road, three (3) people ages 16+ are required for toll-free access if you choose to travel on I-95 Express Lanes (and you must already be registered with South Florida Commuter Services). Participation in the USF Carpool Study does not award free access to the I-95 Express Lanes. Participants must continue to abide by all rules of the I-95 Express Lanes if they choose to use them.
