FasTrak

FasTrak is an electronic toll collection system used on toll roads, bridges, and express lanes in several U.S. states, primarily California. It allows drivers to pay tolls electronically without stopping, using a transponder device mounted on their vehicle's windshield. When a vehicle passes through a toll plaza or an express lane entrance, the transponder communicates with roadside sensors, deducting the toll amount from a pre-paid account.

The system was first implemented in California in the 1990s to improve traffic flow and reduce congestion on toll facilities. Over time, it has expanded to cover a wide network of routes, including highways and bridges in the San Francisco Bay Area, Southern California, and other regions. FasTrak offers various account types, including personal and commercial accounts, with options for different payment methods and replenishment schedules.

Users can manage their FasTrak accounts online or through a mobile app, where they can view toll charges, update payment information, and monitor their account balance. In addition to traditional toll roads, FasTrak is also integrated with many express lanes, which offer faster travel times for a fee, often with dynamic pricing based on real-time traffic conditions. The system aims to provide a convenient and efficient way for drivers to navigate toll facilities.
