    DEPARTMENT OF TRANSPORTATION

    [67 PA. CODE CH. 171]

    School Buses and School Vehicles

    [35 Pa.B. 3039]

       The Department of Transportation, under the authority in 75 Pa.C.S. §§ 4551, 4552, 4553 and 6103 and in accordance with section 6(d) of the Regulatory Review Act (71 P. S. § 745.6(d)) and section 204 of the act of July 31, 1968 (P. L. 769, No. 240) (45 P. S. § 1204), amends Chapter 171 (relating to school bus and school vehicle equipment standards) to read as set forth in Annex A.

    Purpose of Chapter 171

       Chapter 171 sets forth equipment and safety requirements for school buses as provided for in 75 Pa.C.S. § 4552 (relating to general requirements for school buses) and for other vehicles transporting school children as provided for in 75 Pa.C.S. § 4553 (relating to general requirements for other vehicles transporting school children).

    Purpose of this Rulemaking

       The purpose of this rulemaking is to clarify existing provisions of the regulations, reflect innovations adopted by school bus manufacturers and to address concerns raised by the State Police and the Pupil Transportation Advisory Committee (PTAC). The 40 members of the PTAC represent various groups and associations responsible for, or concerned with, pupil transportation.

    Significant Provisions of this Rulemaking

       In addition to the numerous clarifying amendments throughout the chapter, this rulemaking proposes the following significant changes:

       Section 171.18(b) (relating to color) has been amended to permit the service door frame to be painted black and the mirror brackets to be stainless steel with a satin finish.

       Section 171.20(a) (relating to electrical system) has been amended to eliminate the requirement for the chassis manufacturer to temporarily mount the battery to the chassis and has been amended to provide that the battery be mounted on a sliding tray. Section 171.20(c) has been amended to eliminate the requirement that for every school bus to be equipped with a readily accessible terminal strip or plug.

       Section 171.36 (relating to tires and rims) has been amended to clarify that hub cabs that cover the lug nuts are prohibited because they could conceal loose lug nuts, a loose axle or wheel bearing fasteners or oil leaks.

       Section 171.50(b) (relating to doors and emergency exits) has been amended to provide that hasps may not be used. If a hasp were to be inadvertently left in the locked position during student transportation it would render an emergency exit useless. Section 171.50(b)(5)(i) has been amended to prohibit a school bus that is equipped with tinted windows to place the emergency exit labeling on the tinted glass as the tinted glass would make the label difficult to read.

       Section 171.54(a) (relating to heaters) has been amended to eliminate specific heater requirements and to provide for the broader requirement that evenly distributed heat be provided throughout the bus body and to require defrosting for the windshield, driver's side sash and the entrance door. Language has been added to § 171.54(b) detailing minimum requirements relating to auxiliary fuel-fired heating systems.

       Section 171.55(c) (relating to identification) has been amended to allow the dealer insignia to be placed on the rear of the vehicle. Section 171.55(c) is also being amended to update the certification/identification number information from the Interstate Commerce Commission (ICC) number to the United States Department of Transportation identification number, since the ICC no longer exits.

       Section 171.59(b) (relating to lamps and signals) has been amended to allow strobe lights and light emitting diodes to be used in both the 8-way light system and the stopping arm. Section 171.59(d) is being amended to allow the turn signal lamps to be of a shape other than round, as long as they are a minimum of 38 square inches. The rulemaking also requires that the flash rate be between 60--120 flashes per minute.

       Section 171.59(f) has been deleted because the provision is duplicative of § 171.83 (relating to portable emergency warning devices).

       Section 171.86 (relating to fire axe) has been added to prohibit this dangerous piece of equipment. There are a sufficient number of emergency exits required on every school bus.

       Since 171.68(b) (relating to seat belts) has been amended to include both the Type A1 and A2 school buses to be equipped with an integral Type 2 seat belt assembly for the driver. Section 171.68(c) has been being added to require every school bus that is equipped with passenger seat belts to also have at least one web cutter securely mounted in the driver's compartment. This will assist the driver in evacuating the school bus in an emergency.

       Section 171.69(5) (relating to seats and crash barriers) has been amended to require school buses that are equipped with an integrated child restraint seat to have a crash barrier or a seat back of similar size or higher in front of it.

       Section 171.73 (relating to sun shield) has been amended to allow smaller, Type A1 and Type A2 school buses to be equipped with a manufacturer's standard sun shield. New language also allows Type A school buses to also have an interior adjustable transparent sun shield.

       Section 171.76 (relating to ventilation) has been amended to eliminate the requirement for a static-type nonclosable exhaust vent to be installed in a low pressure area of the roof. New language states that the body must be equipped with a ventilation system.

       Section 171.78 (relating to windows) has been amended to allow the edges of glass to either be banded or have a finished edge.

       Section 171.85 (relating to video equipment) is being added to clarify that video equipment is permitted and may be installed at the discretion of the school district or school bus contractor.

       Section 171.92 (relating to aisles) has been amended to clarify that school vehicles may not be equipped with more than two wheelchair positions. New language has also been added to state that each wheelchair seating position is counted as four designated seating positions, in conformity with 49 CFR 571.3(b) (relating to definitions).

       Section 171.99 (relating to restraining devices) has been amended to clarify that specially equipped school vehicles that transport children must comply with 75 Pa.C.S. § 4581 (relating to restraint systems).

       Sections 171.107 and 171.126 (relating to web cutter) are added to require specially equipped school buses and school vehicles to have a least one web cutter securely mounted in the driver's compartment. This will assist the driver when evacuating the specially equipped school bus or school vehicle.

       Section 171.125 (relating to seating) has been amended to require school vehicle seats to be forward facing and must comply with 75 Pa.C.S. § 4581.

    Persons and Entities Affected

       This rulemaking affects persons and entities responsible for the transportation of school children. This includes all 501 school districts in this Commonwealth as well as any organization contracted with to provide pupil transportation. In addition, the State Police will be affected in the performance of school bus vehicle inspections.

    Fiscal Impact

       This rulemaking may impose a cost of approximately $10 for the purchase of a web cutter. Similarly, marginal savings may be anticipated from the elimination of equipment requirements currently in the regulations.

    Regulatory Review

       Under section 5.1 of the Regulatory Review Act (71 P. S. § 745.5a), on May 10, 2005, the Department submitted a copy of this rulemaking to the Office of Attorney General, the Independent Regulatory Review Commission (IRRC) and the Chairpersons of the House and Senate Transportation Committees for review. In addition to the rulemaking, the Committees were provided with a copy of the certification of the Governor that the rulemaking is required to meet an emergency threatening the public health, safety or welfare, as well as a detailed Regulatory Analysis Form prepared by the Department. A copy of this material is available to the public upon request.

    Sunset Date

       The Department is not establishing sunset date for these regulations, since these regulations are needed to administer provisions required under 75 Pa.C.S. (relating to the Vehicle Code). The Department will, however, continue to closely monitor these regulations for their effectiveness.

    Contact Person

       The contact person for technical questions regarding this rulemaking is Chris Ann Miller, Manager, Special Driver Programs, Department of Transportation, Bureau of Driver Licensing, Riverfront Office Center, 1101 South Front Street, 3rd Floor, Harrisburg, PA 17104, (717) 787-6453.
