Senate Bill 1182 is a proposed law in Texas that aims to regulate how money from the state highway fund can be used for toll projects. The bill outlines specific guidelines for the allocation of gasoline tax and other revenue sources to fund the construction, maintenance, and improvement of state road systems, excluding toll roads. It prohibits the use of state highway fund money for toll projects or systems, ensuring that the funds are designated for public road construction and other transportation-related functions. The bill also specifies various amendments to existing transportation laws related to the allocation and use of state highway fund money.
