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. 
2

• 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,
