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 October 24, 2019 request for the Federal Highway 

Administration (FHW A) 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-331 and is valid until a subsequent letter is issued by FHW A 

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 LDS TL-4 

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 ofthe 

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, ~d 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 ofthe AASHTO's MASH. Therefore, the device is eligible for 

reimbursement under the Federal-aid highway program if installed under the range oftested 

conditions. 

Name of system: HighwayGuard LDS TL-4 

Type of system: Longitudinal Barrier 

Test Level: MASH Test Level 4 (TL4) 

Testing conducted by: Holmes Solutions LP 

Date of request: October 24, 2019 

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

attached form. 

In accordance with FHWA's Memo "Federal-aid Reimbursement Eligibility Process for Safety 

Hardware Devices" dated November 12, 2015, FHWA will make note of any reported damage to 

a test vehicle's fuel tank. AASHTO's MASH states "Although not a specific factor in assessing 

test results, integrity of a test vehicle's fuel tank is a potential concern. It is preferable that the 

fuel tank remains intact and not be punctured. Damage or rupture ofthe fuel tank, oil pan, or 

other feature that might serve as a surrogate ofthe fuel tank should be reported" . A test report 

included in this submittal documenting Test 4-12 states "The fuel tank was slightly damaged 

indicating potential for leakage" . 

Full Description of the Eligible Device 

The device and supporting documentation, including reports ofthe crash tests or other testing 

done, videos of any crash testing, and/or drawings ofthe 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 

control number 8-330 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 FHW A to use, 

manufacture, or sell any patented system for which the applicant is not the patent holder. 

• This FHW A eligibility letter is not an expression of any Agency view, position, or 

determination of validity, scope, or ownership of any intellectual property rights to a 

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

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

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

right to review and revoke an earlier eligibility determination after receipt of subsequent 

information related to crash testing.

PRODUCT DESCRIPTION 

(e New Hardware or 

• Significant Modification 

(' Modification to 

Existing Hardware 

HighwayGuard is a steel barrier formed from two profiled, thin gauge sheets being 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 is 540mm wide at the base, 250mm wide at the top, 800mm high and 6,000mm long. Each longitudinal 

section can be connected to an adjoining section using a unique T-connector which engages with vertical pins 

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

surface to create a longitudinal barrier system (wall). The barrier system can be installed with multiple ground 

anchor configurations. This barrier system incorporates ground anchors with a nominal 12m between ground 

anchors in its Limited Deflection System (LDS) configuration. 

CRASH TESTING 

By signature below, the Engineer affiliated with the testing laboratory, agrees in support of this submission that 

all of the critical and relevant crash tests for this device listed above were conducted to meet the MASH test 

criteria. The Engineer has determined that no other crash tests are necessary to determine the device meets 

the MASH criteria.

The longitudinal barrier successfully 

contained and redirected a 1 0000S test 

vehicle impacting the test article at 15.2 

degrees with a velocity of 89.4 km/h. 

No debris or detached elements penetrated 

or showed potential to penetrate the 

occupant compartment. No fragments were 

distributed outside of the vehicle trajectory 

and therefore did not present any undue 

hazard to other traffic, pedestrians or work 

zone personnel. 

Occupant risk factors satisfied the test 

criteria and the vehicle exit trajectory 

remained within acceptable limits. Dynamic 

Deflection was 0.79 m(2.6ft.). Working 

Width was 2.32 m (7.6ft.) at a height of 1.30 

m (4.26ft.)above ground level.
