Reference Guide to Work Zone Traffic Control?

Texas Engineering Extension Service (TEEX) Infrastructure Training & Safety Institute (ITSI)

Material in this guide is largely extracted from the March, 2006 edition of the Manual on Uniform Traffic Control Devices (MUTCD). The user is referred to the MUTCD for all procedures which are not covered in this guide. This document's specific purpose is for quick reference by personnel who are familiar with all applicable laws, requirements, and ordinances. Again, the user is referred to the MUTCD for answers to all specific questions and for a complete listing of all requirements.

Preface In the March, 2006 edition of the TMUTCD, the headings Standard, Guidance, Option, and Support are used to classify the nature of the text that follows. In addition, the text contains variations in type (unbold and bold type) to classify the nature of the text. In the interest of brevity, these headings have been omitted in this Reference Guide, but the type variations (unbold and bold type) have been maintained. 1. Standard -- a statement of required, mandatory, or specifically prohibitive practice regarding a traffic control device. The verb shall is typically used, and the text appears in bold type. Standard text in the Reference Guide appears in bold type. 2. Guidance -- a statement of recommended, but not mandatory, practice in typical situations, with deviations allowed if engineering judgment or engineering study indicates the deviation to be appropriate. The verb should is typically used, and the text appears in unbold type.

3. Option -- a statement of practice that is a permissive condition and carries no requirement or recommendation. Options may contain allowable modifications to a Standard or Guidance. The verb may is typically used, and the text appears in unbold type. 4. Support -- an informational statement that does not convey any degree of mandate, recommendation, authorization, prohibition, or enforceable condition. The verbs shall, should, and may are not used in Support statements, and the text appears in unbold type. 5. Any narrative that was added for explanatory purposes to assist TEEX training efforts is shown in italics. 6. Typical Applications (p. 43-94) were taken from the TxDOT website: 7. Whenever the acronym "TTC" is used in this guide, it refers to "temporary traffic control."
