Mr. Christian Cummings
Acme Barricades, LC
9800 Normandy Boulevard
Jacksonville, FL  32221
Dear Mr. Cummings:
Thank you for your February 22, 2007, correspondence  requesting the Federal Highway Administration (FHWA) acceptance of your  company's model ACME AF temporary sign stand with a galvanized or painted  finish and using aluminum laminate substrate signs for use on the National  Highway System (NHS). Accompanying your  letter was a copy of a letter that proves your company, Acme Barricades LC, has  permission to utilize the acceptance letter WZ-75 issued to Middle Georgia  Signs, Inc. to reproduce the design meeting the specifications of the  previously accepted sign stand Model MGS48A.  The permission letter is enclosed for reference along with a drawing of  the sign stand. Based on the information  received, your company's model ACME AF temporary sign stand with a galvanized  or painted finish utilizing previously accepted aluminum laminate substrate  signs is 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."
Please note the following standard provisions that apply to the  FHWA letters of acceptance:
Our acceptance is limited to the crashworthiness  characteristics of the devices and does not cover  their structural features, nor conformity with the Manual on Uniform Traffic  Control Devices.
Any changes that may adversely influence the  crashworthiness of the device will require a new acceptance letter.
Should the FHWA discover that the qualification testing  was flawed, that in-service performance  reveals unacceptable safety problems, or that the device being marketed is  significantly different from the version that was crash tested, it reserves the  right to modify or revoke its acceptance.
You will be expected to supply potential users with  sufficient information on design and installation requirements to ensure proper  performance.
You will be expected to certify to potential users that  the hardware furnished has essentially  the same chemistry, mechanical properties, and geometry as that submitted for  acceptance, and that they will meet the crashworthiness requirements of the  FHWA and the NCHRP Report 350.
To prevent misunderstanding by others, this letter of  acceptance, designated as number WZ-75A,  shall not be reproduced except in full.  This letter, and the test documentation upon which this letter is based,  is public information. All such letters  and documentation may be reviewed at our office upon request.
This acceptance letter shall not be construed as  authorization or consent by the FHWA to use, manufacture, or sell any patented  device for which the applicant is not the patent holder. The acceptance letter is limited to the  crashworthiness characteristics of the candidate device, and the FHWA, is  neither prepared nor required to become involved in issues concerning patent  law. Patent issues, if any, are to be  resolved by the applicant.Sincerely yours,
