A Level I Signs & Markings Specialist should, by nature of his certification title, have mastered the basic principles behind signing and pavement marking. Although the individual who is approved to take the Level I exam may have had a lot of field experience, the exam will require that he be able to communicate this knowledge in a written format. The best way to prepare for this challenge is to begin to review the topics that will be covered on the exam. Most of the Level I review material has been derived from MUTCD Parts I, IIA, IIB, IIC, IID, III, V, VI, VII, and VIII. The remaining material has been derived from the following publications: "FHWA's Standard Highway Signs", "FHWA's Standard Alphabets For Highway Signs and Pavement Markings", "TRB's NCHRP Synthesis 157: Maintenance Management of Street and Highway Signs", and "ITE's Traffic Engineering Handbook," 4th Edition pp. 139-277.
