Dear Mr. Goode :

Thank you for your correspondence requesting the Federal Highway Administration (FHWA) acceptance of your company's SZ-412-2S Portable Sign Stand with 48 x 48 inch, 0.080 inch thick solid aluminum signs for use in work zones on the National Highway System (NHS). Accompanying your letter was the FHWA Office of Safety Design form you completed and a DVD compilation of relevant crash tests. You requested that we find this sign stand acceptable for use on the NHS under the provisions of the National Cooperative Highway Research Program (NCHRP) Report 350 "Recommended Procedures for the Safety Performance Evaluation of Highway Features."

This letter is the acknowledgement of the FHWA's acceptance of your request. The results of the testing met the FHWA requirements, and therefore, the device detailed in the enclosed drawing is acceptable for use on the NHS under the range of conditions tested, when proposed by a State.

A PDF version of your completed form has been modified by the addition of the FHWA acceptance letter number and the date of our review. The form, of which a copy is enclosed for reference, will be posted to our Web site in the near future. Please note that future submissions must include an electronic copy of the form that may be edited, plus a hard copy signed by the engineer from the crash test laboratory.

Thank you for working with us as we institute this new review and acceptance process.

Sincerely yours,

/original signed by /
