Dear Mr. Sandy:

In your letter of November 27, 2007, you requested the Federal Highway Administration’s (FHWA) acceptance of your company’s A-frame Type I and Type II barricades as crashworthy traffic control devices for use on the Accompanying your letter were drawings of the barricades and a letter granting permission to your company from Plastic Safety Systems to copy the design of the previously crash tested and accepted barricades. You requested that we find your company’s barricades equivalent and 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.”

Your company’s barricades are nearly identical in size, form, and function and are considered equivalent to Plastic Safety System’s barricades that have been crash tested and accepted for use with and without a lightweight light attached. The Traffic Safety Service’s (TSS) Type I and Type II barricades are manufactured using HPDE plastic and the total weight is between 22 to 64 pounds depending on the length of barricade rail configuration. The lengths of barricade rails vary and may be configured in 4, 6, 8, 10, or 12 foot lengths. The A-frames supporting the barricade rail(s) measure 40.25 inches (1.02 m) tall and 28.9 inches (0.73 m) at the base. Drawings of the devices are enclosed for reference. Additionally, you enclosed a copy of a letter from Plastic Safety Systems granting you permission to copy their barricade design that was found to be crashworthy based on testing as described in the FHWA acceptance letter WZ-102 issued in 2002.

Based on our review, your TSS Type I and Type II barricades are equivalent to the previously accepted barricades in acceptance letter WZ-102. Since you have obtained permission to copy the previously accepted design, your equivalent barricade designs are crashworthy and are accepted by the FHWA as a Category 2 device with and without a lightweight light securely attached.

Please note the following standard provisions that apply to the FHWA letters of acceptance:

Sincerely yours,

George E. Rice
