4902 - Restrictions on use of highways and bridges.

     § 4902.  Restrictions on use of highways and bridges.        (a)  Restrictions based on condition of highway or bridge.--     The Commonwealth and local authorities with respect to highways     and bridges under their jurisdictions may prohibit the operation     of vehicles and may impose restrictions as to the weight or size     of vehicles operated upon a highway or bridge only when they     determine by conducting an engineering and traffic study as     provided for in department regulations that the highway or     bridge may be damaged or destroyed unless use by vehicles is     prohibited or the permissible size or weight of vehicles is     reduced. School buses, emergency vehicles and vehicles making     local deliveries or pickups may be exempted from restrictions on     the use of highways imposed under this subsection.        (b)  Restrictions based on traffic conditions.--The     Commonwealth and local authorities with respect to highways and     bridges under their jurisdictions may prohibit the operation of     vehicles and may impose restrictions as to the weight or size of     vehicles operated upon a highway or bridge whenever they     determine that hazardous traffic conditions or other safety     factors require such a prohibition or restriction. School buses,     emergency vehicles and vehicles making local deliveries or     pickups may be exempted from restrictions on the use of highways     imposed under this subsection.        (c)  Permits and security.--The Commonwealth and local     authorities may issue permits for movement of vehicles of size     and weight in excess of restrictions promulgated under     subsections (a) and (b) with respect to highways and bridges     under their jurisdiction and may require such undertaking or     security as they deem necessary to cover the cost of repairs and     restoration necessitated by the permitted movement of vehicles.     In reference to subsection (a), the Commonwealth and local     authorities shall not refuse to issue a permit with respect to a     highway under their jurisdiction if there is no reasonable     alternate route available. For purposes of this section,     "reasonable alternate route" shall mean a route meeting the     criteria set forth in department regulations relating to traffic     and engineering studies.        (d)  Designation of alternate routes.--            (1)  In conjunction with the exercise of the powers set        forth in subsections (a) and (b), the Commonwealth may        designate alternate routes for vehicles in excess of        specified weights or sizes. Such alternate routes may utilize        portions of the Pennsylvania Turnpike.            (2)  In conjunction with the exercise of the powers set        forth in subsection (c), when refusing to issue a permit with        respect to a highway under their jurisdiction, the        Commonwealth and local authorities may conduct or cause to be        conducted an alternate route study. The elements of an        engineering and traffic study conducted to designate an        alternate route pursuant to this section shall consist of the        same elements found in department regulations.        (e)  Erection of signs.--The Commonwealth and local     authorities shall erect or cause to be erected and maintained     restriction signs designating the restrictions within 25 feet of     each end of a bridge or portion of highway restricted as     provided in subsection (a) or (b). In the case of a restriction     on a bridge or on a highway which does not begin or end at an     intersection with an unrestricted highway, the Commonwealth or     local authorities shall also place an advance informational sign     at the intersection nearest each end of the restricted bridge or     portion of highway which would allow drivers to avoid the     restricted bridge or portion of highway. No person shall be     convicted of violating subsection (a) or (b) unless the     restriction sign designating the restricted bridge or portion of     highway to traffic moving in the direction the person was     driving was posted as required in this subsection. However,     failure to post the restriction sign designating the restricted     bridge or portion of highway to traffic moving in the opposite     direction or failure to post any advance informational sign     shall not constitute a defense to a violation of this section.        (f)  Actions to be in accordance with department     regulations.--All actions taken under authority of this section     shall be taken in accordance with department regulations.        (f.1)  Local ordinances superseded.--Notwithstanding any     other provision of law, local authorities are prohibited from     enacting or enforcing ordinances inconsistent with the     provisions contained in this section.        (g)  Penalty.--            (1)  Any person operating a vehicle or combination upon a        highway or bridge in violation of a prohibition or        restriction imposed under subsection (a) is guilty of a        summary offense and shall, upon conviction, be sentenced to        pay a fine of $75, except that any person convicted of        operating a vehicle with a gross weight in excess of a posted        weight shall, upon conviction, be sentenced to pay a fine of        $150 plus $150 for each 500 pounds, or part thereof, in        excess of 3,000 pounds over the maximum allowable weight.            (2)  Any person operating a vehicle or combination in        violation of a prohibition or restriction imposed under        subsection (b) is guilty of a summary offense and shall, upon        conviction, be sentenced to pay a fine of not more than $500.
