Document:
The Department of Transportation (Department), under the authority of 75 Pa.C.S. §§ 3353, 3354, 6103, 6105, 6121, 6122, 6123 and 6123.1, deletes Chapters 201, 203, 204, 211 and 217 and adds Chapter 212 (relating to official traffic-control devices) to read as set forth in Annex A. Included as part of the new Chapter 212, the Department adopts the National Manual on Uniform Traffic Control Devices (MUTCD) as published by the Federal Highway Administration (FHA).
The purpose of Chapter 212 is to adopt the National MUTCD, to establish new regulations regarding additional study requirements, warrants, principles and guidelines not included in the MUTCD; and to establish greater uniformity for the design, location and operation of all official traffic signs, signals, markings and other traffic-control devices within this Commonwealth.
With the promulgation of this final-form rulemaking, the most recent edition of the National MUTCD, published by the FHA, will become the standard for traffic control in this Commonwealth. As provided in 75 Pa.C.S. §§ 6103(c) and 6121 (relating to promulgation of rules and regulations by department; and uniform system of traffic-control devices), this final-form rulemaking will also establish additional regulations regarding study requirements, warrants, principles and guidelines and insure uniformity for the design, location and operation of all official signs, signals, markings and other traffic-control devices within this Commonwealth, incorporating, revising and adding to regulations in deleted Chapters 201, 203. 204, 211 and 217.
The proposed rulemaking was published at 34 Pa.B. 4712 (August 28, 2004) and the public was invited to submit comments. The proposed rulemaking was also submitted to the Independent Regulatory Review Commission (IRRC) and to the House and Senate Transportation Committees. Comments were received from IRRC and from the public. The Department considered the written comments in formulating this final-form rulemaking. A separate comment and response document has been prepared to address these comments and is available upon request. Several commentators expressed concern that the final-form rulemaking would require local municipalities to be responsible for the installation and maintenance of stop signs, stop ahead signs and other traffic controls on State highways where they intersect with local roads. As explained more fully in the response document, it is the intention of the final-form rulemaking to clarify local responsibility for stop signs and stop ahead signs on local road approaches where they intersect with State highways. The Department will retain responsibility for the installation and maintenance of these signs and other traffic controls on State highways, except as specifically provided for in this final-form rulemaking.
This final-form rulemaking affects the Commonwealth, the Pennsylvania Turnpike Commission, local authorities, contractors, consultants, utility companies, vendors, and the motoring public.
Elimination of current Department Publications Nos. 68, 201 and 203 is projected to annually reduce publication costs by approximately $30,000. It is estimated that changes in signing requirements, particularly in work zones, will result in approximately $6.0 million savings to the regulated community and State and local governments.
Contractors and highway agencies may have some modest savings since fewer traffic-control devices will be required in some construction and maintenance projects. In addition, consultants and suppliers of traffic-control devices should be able to be more efficient due to increased uniformity from state to state.
Under section 5(a) of the Regulatory Review Act (71 P. S. § 745.5(a)), on August 12, 2003, the Department submitted a copy of the notice of proposed rulemaking, published at 34 Pa.B. 4712, to IRRC and the Chairpersons of the House and Senate Transportation Committees for review and comment.
Under section 5.1(j.2) of the Regulatory Review Act (71 P. S. § 745.5a(j.2)), on December 14, 2005, the final-form rulemaking was deemed approved by the House and Senate Committees. Under section 5.1(e) of the Regulatory Review Act, IRRC met on December 15, 2005, and approved the final-form rulemaking.
The Department is not establishing a sunset date for these regulations, since these regulations are needed to administer provisions required under 75 Pa.C.S. (relating to Vehicle Code). The Department, however, will continue to closely monitor these regulations for their effectiveness.
The contact person for this proposed rulemaking is Glenn C. Rowe, P. E., PTOE, Division Chief, Bureau of Highway Safety and Traffic Engineering, 400 North Street, 6th Floor, Harrisburg, PA 17120-0064, (717) 787-3620.

The MUTCD is adopted in its totality except where this chapter clearly indicates that it is not being adopted, or that additional warrants or criteria are being provided.
(b) Modification of Federal statutes, regulations or provisions. As provided in 75 Pa.C.S. § 6103(d), if the MUTCD is amended or modified by the Federal Highway Administration, the amendment will take effect on the effective date specified by the Federal Highway Administration unless the Department publishes a notice in the Pennsylvania Bulletin stating that the amendment or modification will not apply.
