The "Bus Parity and Clarity Act" aims to ensure equal access and treatment for over-the-road buses on certain transportation infrastructure. It clarifies that these buses, whether in scheduled or charter service , should be afforded the same rates, terms, and conditions as public transportation vehicles when using toll roads, bridges, tunnels, ferries, and high-occupancy vehicle (HOV) facilities. Specifically, the bill amends sections of title 23, United States Code, to explicitly include buses in charter service within existing equal access provisions. It also mandates that public authorities participating in value pricing pilot programs provide over-the-road buses with access comparable to public transportation vehicles. Furthermore, the Federal Highway Administration will be required to annually publish a publicly available database detailing the rates, terms, and conditions for all toll facilities covered by these equal access requirements, enhancing transparency for bus operators.
