How does the FasTrak electronic toll collection system work?
To use the I-15 Express Lanes as a solo driver, you must have a FasTrak transponder. The transponder is a small radio device that is mounted inside the vehicle on the windshield. It identifies the customer’s prepaid toll account. Overhead antennae in the Express Lanes read the transponder and deduct the correct toll electronically from the customer’s FasTrak prepaid account. An electronic sign located before the entrance to the existing Express Lanes gives customers advance notice of the current toll as they approach the lanes. Where is the toll rate posted? Electronic signs with the posted toll rate are located in advance of every I-15 Express Lanes entrance. How do I sign up for FasTrak?
