Commuter Protection Act - Amends the Surface Transportation and Uniform Relocation Assistance Act of 1987 to expand the requirement that certain bridge tolls be just and reasonable to all bridges or tunnels constructed on a federal-aid highway. (Current law applies the just and reasonable toll requirement only to bridges constructed under the Bridge Act of 1906, the General Bridge Act of 1946, or the International Bridge Act of 1972.)
Requires that tolls for all such bridges and tunnels be subject to review and regulation by the Secretary of Transportation (DOT), upon complaint or the initiative of the Secretary, including with respect to increases in the amount of tolls.
Directs the Secretary to promulgate regulations to define, determine, and, when appropriate, prescribe just and reasonable toll rates.
Requires that such regulations: (1) establish an administrative complaint process for aggrieved persons to challenge such determinations or toll rate increases on bridges or tunnels, (2) authorize the Secretary or an administrative law judge to conduct investigations and hold formal hearings on such complaints, and (3) permit complainants to seek judicial review of a final administrative determination in a U.S. district court.
Directs the Comptroller General to: (1) evaluate the use of tolls by interstate authorities to maintain and improve surface transportation facilities, and (2) make recommendations to increase transparency and accountability of the funding decisions by those authorities.
