Dear Mr. Eckert:
This letter is in response to your August 1, 2014 request  for the Federal Highway Administration (FHWA) to review a roadside safety  device, hardware, or system for eligibility for reimbursement under the  Federal-aid highway program. This FHWA  letter of eligibility is assigned FHWA control number CC-87D and is valid until  a subsequent letter is issued by FHWA that expressly references this device.
**Decision**
  The following devices are eligible, with details provided  in the form which is attached as an integral part of this letter:
QuadGuard System Modification***Scope of this  Letter***
To be found eligible for Federal-aid funding, modified roadside safety devices should meet the crash test and evaluation criteria contained in the National Cooperative Highway Research Program (NCHRP) Report 350. However, the FHWA, the Department of Transportation, and the United States Government do not regulate the manufacture of roadside safety devices. Eligibility for reimbursement under the Federal-aid highway program does not establish approval, certification or endorsement of the device for any particular purpose or use.
This letter is not a determination by the FHWA, the Department of Transportation, or the United States Government that a vehicle crash involving the device will result in any particular outcome, nor is it a guarantee of the in-service performance of this device. Proper manufacturing, installation, and maintenance are required in order for this device to function as tested.
This finding of eligibility is limited to the crashworthiness of the system and does not cover other structural features, nor conformity with the Manual on Uniform Traffic Control Devices.
***Eligibility for  Reimbursement***
FHWA previously issued an eligibility letter for the roadside safety system described in your pending request. Your pending request now identifies a modification to that roadside safety system.
The original roadside safety device information is provided  here:
Name of system:
QUESTTMType of system:
  Crash CushionDate of original request:
  January 28, 2005Date of original FHWA eligibility letter:
February 17, 2005FHWA Control number:
HSA-10/CC-87The modification(s)  to the QuadGuard covered by this letter are:
Elimination of separate Product and Assembly manuals and provides a singular Product Description Assembly Manual for the QUEST System family.FHWA concurs with the recommendation of the accredited crash  testing laboratory as stated within the attached form.

***Full Description  of the Eligible Device***
The device and supporting documentation, including reports  of the crash tests or other testing done, videos of any crash testing, and/or  drawings of the device, are described in the attached form.
***Notice***
If a  manufacturer makes any modification to any of their roadside safety hardware  that has an existing eligibility letter from FHWA, the manufacturer must notify  FHWA of such modification with a request for continued eligibility for  reimbursement. The notice of all  modifications to a device must be accompanied by:

  Significant modifications – For these modifications, crash        test results must be submitted with accompanying documentation and        videos.
    Non-signification modifications – For these modifications, a        statement from the crash test laboratory on the potential effect of the        modification on the ability of the device to meet the relevant crash test        criteria.FHWA's determination of continued  eligibility for the modified hardware will be based on whether the modified  hardware will continue to meet the relevant crash test criteria.
You are expected to supply potential users with sufficient  information on design, installation and maintenance requirements to ensure  proper performance.
You are expected to certify to potential users that the  hardware furnished has the same chemistry, mechanical properties, and geometry  as that submitted for review, and that it will meet the test and evaluation  criteria of the NCHRP Report 350.
Issuance of this  letter does not convey property rights of any sort or any exclusive privilege.  This letter is based on the premise that information and reports submitted by  you are accurate and correct. We reserve the right to modify or revoke  this letter if: (1) there are any  inaccuracies in the information submitted in support of your request for  this letter, (2) the qualification testing was flawed, (3) in-service  performance or other information reveals safety problems, (4) the system is  significantly different from the version that was crash tested, or (5) any  other information indicates that the letter was issued in error or otherwise  does not reflect full and complete information about the crashworthiness of the  system.

***Standard Provisions***

To prevent misunderstanding by others, this letter of       eligibility designated as FHWA control number CC-87D shall not be       reproduced except in full. This       letter and the test documentation upon which it is based are public       information. All such letters and documentation       may be reviewed upon request.
     This letter shall not be construed as authorization or       consent by the FHWA to use, manufacture, or sell any patented system for       which the applicant is not the patent holder.
     If the subject device is a patented product it may be  considered to be proprietary. If  proprietary systems are specified by a highway agency for use on Federal-aid  projects: (a) they must be supplied through competitive bidding with equally  suitable unpatented items; (b) the highway agency must certify that they are  essential for synchronization with the existing highway facilities or that no  equally suitable alternative exists; or (c) they must be used for research or  for a distinctive type of construction on relatively short sections of road for  experimental purposes.Our regulations concerning proprietary products are contained in Title 23, Code of Federal Regulations, Section 635.411.
Sincerely yours,
