Dear Mr. Dyke:
            This letter is in response to your December 23, 2015 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 B-40B 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:
            Narrow QuickChange Moveable Barrier QMB modifications***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:
                  Narrow QuckChange Moveable Barrier modificationsType of system:
                  Portable / Moveable Longitudinal BarrierTest Level
                  NCHRP Report 350 TL-3Date of original request:
                  December 23, 2015Original FHWA letter:
                  B-40 dated August 27, 1997FHWA Control number:
                  B-40
            The pending modification(s) consists of the following  changes:
1) Reduce diameter of bolt hole  in base plate for rubber foot attachment
2) Stronger pin retaining clip
3) Modified spring pusher plate
4) More durable hydraulic breather  cap
            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 B-40B shall not be reproduced except in full. This letter and the test documentation       upon which it is based are public information.Â  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,
