Davis, Dennis . 2009. Be Seen: High-Visibility Outer Garment Required When Working in Highway Rights-of-Way. 0967 2311. Missoula, MT: U.S. Department of Agriculture, Forest Service, Missoula Technology and Development Center. 2 p.

A regulation that took effect in late 2008 generally requires persons working in the rights-of-way of Federal-aid highways (the interstates and U.S. highways) to wear high-visibility outer garments (vests, coats, or coveralls). These garments must meet the ANSI/ISEA 107-2004 class 2 standards, which require at least 775 square inches of highly visible colored fluorescent materials and at least 201 square inches of retroreflective material (that will bounce light directly back toward its source). Forest Service vehicles should carry at least two high-visibility vests meeting the ANSI/ISEA 107-2004 Class 2 standard so employees will be able to wear the vests when changing a flat tire or doing other work in the highway right-of-way. Updated information for firefighters is available at:
