Dear Mr. Simms:

In your letter of August 14, 2007, you  requested the Federal Highway Administration (FHWA) acceptance of your  company’s TSI S102 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 and test report documentation including a DVD compilation  of relevant crash tests conducted by E-Tech Testing Services. A summary of the test results that include a  drawing and specifications are enclosed for reference. You requested that we find this portable  A-frame sign 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 original completed  form has been modified by the addition of the FHWA acceptance letter number WZ-259. The  form, of which a copy is enclosed for reference, will be posted on our Web site  in the near future.
Sincerely yours,
George E. Rice
