Welcome to ATSSA’s Retroreflectivity Website

 

The ATSSA Retroreflectivity website debuted in August 2006. This website is meant to be a one-stop shopping location for retroreflective issues related to transportation. Since the site is new, there is still much work that needs to be completed. We have tried to provide you with enough information to get a sense of where we’re headed. Your feedback is important. Please let us know what you think of the website. Thanks!

FHWA Resources

Retroreflectivity is the scientific term that describes the ability of a surface to return light back to its source. Retroreflective signs and pavement markings bounce light from vehicle headlights back toward the vehicle and the driver's eyes. Signs and markings that efficiently return the light appear brighter and easier to see and read.

Retroreflectivity, or nighttime visibility of signs and pavement markings, provide: (1) critical information to drivers at night, (2) help drivers navigate the road during nighttime hours, (3) enhance traffic flow and driver mobility, and (4) promote safe driving.

  • Interim Final Rule Issued to Revise Worker Visibility Rule

    On November 21, the FHWA issued an interim final rule revising the Worker Visibility Rule (23CFR 634) to create an exemption for the firefighting community.  This interim Final Rule allows firefighters or other emergency responders working within the right-of-way of a Federal-aid highway, engaged in emergency operations that directly expose them to flame, fire, heat, and/or hazardous materials to wear retroreflective turn-out gear that is specified and regulated by other organizations, such as the National Fire Protection Association.  Firefighters or other emergency responders working within the right-of-way of a Federal-aid highway, engaged in any other types of operations shall wear high-visibility safety apparel  as defined in this Rule.   The FHWA decided to issue this interim Final Rule to address safety concerns raised by fire fighting community.   The interim Final Rule has been published in the Federal Register went into effect on November 24, 2008. This rule can be accessed by clicking here.
