Standards for Uniform Traffic Control Devices
WHEREAS the Transportation Commission of Wyoming on March 17, 2005, adopted the 2003 edition of the Manual on Uniform Traffic Control Devices for Streets and Highways as approved by the Federal Highway Administrator as the state and national standard for application on all classes of highways; and
WHEREAS, that manual has been updated by the 2009 edition; and
WHEREAS, the Wyoming Department of Transportation, through the Transportation Commission of Wyoming, desires to adopt the 2009 edition of the Manual on Uniform Traffic Control Devices with the following addition; and
WHEREAS, under Section 1A.13, Definitions of Headings, Words, and Phrases in this Manual, the definition of a Standard shall be amended in Wyoming so that engineering judgment or an engineering study can be used to modify any standard, guidance, option, or support statement as shown in the 2009 edition of the Manual on Uniform Traffic Control Devices based on unusual site-specific conditions that make compliance with the standard impossible or impractical; and
WHEREAS, impossible is defined as, “a fact, condition, circumstance, or performance that cannot occur, exist, or be done”; and
WHEREAS, impractical is defined as, “a fact, condition, circumstance, or performance that would cause extreme and/or unreasonable difficulty, including unanticipated increases in effort and/or expense and/or diminished safety”; and
WHEREAS, unusual is defined as, “those facts, conditions, circumstances, or anticipated performances determined by an engineer to depart from or exist outside of the typical or normal”; and
WHEREAS, this resolution is consistent with proposed language contained in the Federal Highway Administration rule makings issued on August 31, 2011, revising Section 1A.13 and on August 2, 2011, amending Section 1A.09; and
WHEREAS, the Commission reserves the right to amend this resolution pending the outcome of the rule makings discussed in the previous “whereas.”
NOW THEREFORE, BE IT RESOLVED by the Transportation Commission of Wyoming, the 2009 edition of the Manual on Uniform Traffic Control Devices for Streets and Highways be adopted as the state’s standard as modified by the preceding, and excepting those provisions in conflict with existing state requirements.
A copy of the manual is on file in the office of the Secretary of the Commission.
