Mr. Adrian Bullock 

Highway Care Ltd. 

The Highlands, Detling, Maidstone, Kent 

ME14 3HT 

United Kingdom 

Dear Mr. Bullock: 

This letter is in response to your August 18, 2019 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-329 and is valid until a subsequent letter is issued by FHWA that expressly 

references this device. 

Decision 

The following device is eligible within the length-of-need, with details provided in the form 

which is attached as an integral part of this letter: 

• HighwayGuard TL-3 

Scope of this Letter 

To be found eligible for Federal-aid funding, new roadside safety devices should meet the crash 

test and evaluation criteria contained in the American Association of State Highway and 

Transportation Officials’(AASHTO) Manual for Assessing Safety Hardware (MASH). 

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. 
 

2 

Eligibility for Reimbursement 

Based solely on a review of crash test results and certifications submitted by the manufacturer, 

and the crash test laboratory, FHWA agrees that the device described herein meets the crash test 

and evaluation criteria of the AASHTO’s MASH. Therefore, the device is eligible for 

reimbursement under the Federal-aid highway program if installed under the range of tested 

conditions. 

Name of system: HighwayGuard 

Type of system: Longitudinal Barrier 

Test Level: MASH Test Level 3 (TL3) 

Testing conducted by: Holmes Solutions LP 

Date of request: August 18, 2019 

FHWA concurs with the recommendation of the accredited crash testing laboratory on 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 

This eligibility letter is issued for the subject device as tested. Modifications made to the device 

are not covered by this letter. Any modifications to this device should be submitted to the user 

(i.e., state DOT) as per their requirements. 

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 AASHTO’s MASH.

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 

wntrol number B-329 shall not be reproduced except in full. This letter and the test 

docuntentation upon which it is based are public information. All such letters and 

doctiffi.entation 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. 

• This FHWA eligibility letter is not an expression ofany Agency view, position, or 

determination ofvalidity, scope, or ownership ofany intellectual property rights to a 

specific device or design. Further, this letter does not impute any distribution or licensing 

rights to the requester. This FHWA eligibility letter determination is made based solely 

on the crash-testing information submitted by the requester. The FHWA reserves the 

right to review and revoke an earlier eligibility determination after receipt ofsubsequent 

information related to crash testing.

HighwayGuardisasteel barrier formed from two profiled, thin gaugesheetsbeing welded together along the 

join at the top, and to feet at the base, to form a long hollow section, the overall dimensions of each barrier 

section is540mm wideat the base,250mm wideat the top,800mm highand 6,000mmlong.Each longitudinal 

sectioncanbeconnected to an adjoiningsection using a uniqueT-connector which engageswith vertical pins 

located at the end of each section. These barrier sections are joined together and laid out along the road 

surfaceto createalongitudinal barriersystem (wall).Thebarriersystem can be installed with multiple ground 

anchor configurations. This barrier system incorporates ground anchors at a maximum of 60.0m between 

groundanchorsin itsstandard configuration.
