On Sept. 4, 2008, the National Work Zone Safety Information Clearinghouse held a free informational session on the new FHWA regulation that takes effect November 24, 2008. This new standard requires the use of high visibility clothing (as defined by ANSI/ISEA 107 standard) when working in the right-of-way on federal-aid highways. Speakers were Hari Kalla, MUTCD Team Leader for FHWA’s Office of Operations and Janice Bradley, Technical Director of the International Safety Equipment Association (ISEA).
