WASHINGTON — On November 24 2008, a new federal regulation (23 CFR 634) goes into effect mandating that anyone working in the right-of-way of a federal-aid highway must be wearing high-visibility clothing that meets the requirements of ANSI / ISEA 107; 2004 edition class 2 or 3.
This requirement will apply to all emergency responders.
There is further information on the Responder Knowledge Base website including links to download some of the relevant documents, information concerning ANSI / ISEA 207 Public Safety Vests, certain exceptions for police officers, and information about proposed rules changes to later expand the law to cover all public roadways.
