What is regulation 23 CFR 634?
A new federal regulation, 23 CFR 634, mandating that anyone working in the right-of-way of a federal-aid highway must be wearing high-visibility clothing that meets the requirement of ANSI/ISEA 107-2004 edition Class 2 or 3. This requirement applies to all emergency responders. The Code of Federal Regulations Title 23 (highways) Part 634 was originally published in the Federal Register Vol 71, No226, pp 67792-67800. The rule itself (634.3) simply states that: “All workers within the right-of-way of a Federal-aid highway who are exposed either to traffic (vehicles using the highway for purposes of travel) or to construction equipment within the work area shall wear high-visibility safety apparel.
