Dear Mr. Bullock: 

In Reply Refer To: 

HSST-1/B-356 

This letter is in response to your December 31, 2020 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-356 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 – Quadguard Crash Cushion Transition

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.

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 – 

Quadguard Crash Cushion Transition Type 

of system: Longitudinal Barrier

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.

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-356 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

• 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 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 FHWA eligibility letter determination is made based solely 

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

PRODUCT DESCRIPTION

New Hardware or 

Significant Modification

Modification to 

Existing Hardware

The tested product is a short section of HighwayGuard barrier profile and accompanying panels and frame 

work which is used to transition between HighwayGuiard steel barrier and the steel re-directive crash cushion. 

The crash cushion chosen for the testing for this submission was the QuadGuard M10.

The transition is made up of a short section of HighwayGuard profile mounted to a ground plate which is 

designed to be anchored to the ground between the end of the HighwayGuard Barrier wall and the crash 

cushion. There are side panels bolted to the Highway Guard and the crash cushion back up which are 

designed as a transition between the differing profiles of the HighwayGuard barrier and the crash cushion and 

to safely redirect any errant vehicle coming into contact with the system between the barrier wall and the 

crash cushion.

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.

3-10 (1100C) Non-Relevant Test, not conducted

3-11 (2270P) Non-Relevant Test, not conducted

3-20 (1100C) Non-Critical, not conducted

3-32 (2270P)

The transition successfully contained and 

redirected a 2270P test vehicle impacting 

the test article at 25.0 degrees in reverse 

direction with a velocity of 100.1 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 0.37 m(1.21 ft.). Working 

Width was 1.22 m (4.0ft.)
