Why am I receiving a new transponder?

Per California’s Office of Administrative Law, beginning in January 2019, all tolling agencies in California must be working toward the adoption and implementation of 6C tolling technology. The 6C tolling technology allows for electronic toll collection transponders to be in the form of a sticker, which is less costly to procure, store and distribute and is less obtrusive for the customer than the transponder required by the former Title 21 tolling technology. More importantly, the action helps advance plans for achieving nationwide tolling interoperability.
