Carpools (2+ people), vanpools, motorcycles, and other toll-exempt vehicles may travel toll free with a FasTrak Flex or FasTrak CAV toll tag.
Do babies count for FasTrak?
But to reiterate, carpoolers and motorcycles still must have a FasTrak transponder. Children count as a person in a vehicle. In other words, Mother or Father + Child = Toll Free Carpool Travel.
Is FasTrak free for motorcycles?
Motorcycles can travel for free without a FasTrak transponder. If a motorcyclist has a transponder, they can set it to 2 or 3 plus people to avoid paying the toll.
