Hardware Eligibility Letters

Hardware, such as barriers, sign supports, and work zone devices are commonly used to reduce the potential severity of crashes on the roadside. Crash testing is used to evaluate the crashworthiness of these devices.

Section 508 of the Rehabilitation Act of 1973 (Section 508) is a Federal law that requires Federal agencies to make electronic and information technology (EIT) accessible to people with disabilities in accordance with standards issued by the U.S. Access Board. The Access Board’s Section 508 Standards address the accessibility requirements for Information and Communication Technology (ICT), which encompasses EIT covered by Section 508, that federal agencies procure, develop, maintain, or use. Eligibility letters that FHWA posts on this website constitute ICT that must conform to the Section 508 Standards, and particularly the Section 508 Standards for electronic content at Section E205. These standards require electronic content to conform to Level A and Level AA Success Criteria and Conformance Requirements in WCAG 2.0 (Section E205.4). Therefore, FHWA posts eligibility letters on this website with attachments (manufacturers’ hardware drawings, test summaries, etc.) that meet Section 508 requirements.
