Opening a FasTrak account and getting a transponder has never been easier.
For $34.99, each transponder comes with $40 in pre-paid toll credits, of which $5.01 in free toll credits is good for travel on the facility where the account is registered (I-15 Express Lanes or South Bay Expressway). Current I-15 Express Lanes and South Bay Expressway customers can add transponders to their account under this promotion and this offer also can be combined with our Refer-A-Friend promotion.
