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
