Dear Mr. Yetzer :
Thank you for your February 15 letter requesting Federal Highway Administration (FHWA) acceptance of your company's QRS Vertical Sign Stand as a crashworthy traffic control device for use in work zones on the National Highway System (NHS). Accompanying your letter was the FHWA Office of Safety Design form completed and signed by you and E-Tech Testing Services, and a DVD compilation of relevant crash tests conducted by E-Tech. You requested that we find this stand acceptable for use on the NHS under the provisions of National Cooperative Highway Research Program 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 described in the form and detailed in the enclosed drawings is acceptable for use on the NHS under the range of conditions tested, when proposed by a State. The form, of which a copy is enclosed for reference, will be posted on our website in the near future.
You also asked for the following practical field-use scenarios:
Thank you for working with us as we institute this new review and acceptance process.
/Original Signed by/
