SECTION 1. SHORT TITLE.

    This Act may be cited as the ``Commercial Truck Highway Safety 
Demonstration Program Act of 2003''.

SEC. 2. FINDINGS.

    Congress makes the following findings:
            (1) Public safety on the highways of the United States is a 
        paramount concern of all who use the highways and all who 
        prescribe public policy for the use of those highways, 
        including public policy on the operation of heavy commercial 
        trucks on highways.
            (2) Federal highway funding law effectively imposes a limit 
        of 80,000 pounds on the weight of vehicles permitted to use 
        Interstate System highways.
            (3) The administration of this law in Maine has forced 
        heavy tractor-trailer and tractor-semitrailer combination 
        vehicles traveling into Maine from neighboring States and 
        Canada to divert onto small State and local roads where higher 
        vehicle weight limits apply under Maine law.
            (4) The diversion of those vehicles onto such roads causes 
        significant economic hardships and safety challenges for small 
        communities located along those roads.
            (5) Permitting heavy commercial vehicles, including tanker 
        trucks carrying hazardous material and fuel oil, to travel on 
        Interstate System highways in Maine--
                    (A) would enhance public safety by reducing--
                            (i) the number of heavy vehicles that use 
                        town and city streets in Maine; and
                            (ii) as a result, the number of dangerous 
                        interactions between those heavy vehicles and 
                        such other vehicles as school buses and private 
                        vehicles; and
                    (B) would reduce the net highway maintenance costs 
                in Maine because the Interstate System highways, unlike 
                the secondary roads of Maine, are built to accommodate 
                heavy vehicles and are, therefore, more durable.

SEC. 3. DEFINITIONS.
