Dear Mr. Eckert: 

We received your correspondence of April 21, 2022 requesting issuance of a reimbursement 

eligibility letter under the Federal-aid highway program for the roadside safety system, device, 

design, product, or hardware (collectively “device”) described below. This letter is assigned 

Federal Highway Administration (FHWA) control number CC-172. 

ELIGIBILITY LETTERS

The FHWA issues Federal-aid reimbursement eligibility letters for new roadside safety devices

that are crash tested in accordance with the industry standard of the American Association of 

State Highway and Transportation Officials (AASHTO) Manual for Assessing Safety Hardware 

(MASH). 

FHWA, the Department of Transportation, and the United States (government) do not regulate 

roadside safety devices, crash test facilities, or the manufacturing industry. Issuance of 

eligibility letters is discretionary and provided only as a service to the states. FHWA may, at its 

discretion, decline to issue, revise, or rescind an eligibility letter. Eligibility letters are only 

issued by the FHWA headquarters Office of Safety. 

Eligibility letters are issued only as notice to the states that a device is eligible for reimbursement 

under the Federal-aid highway program. They do not establish approval or certification for any 

other purpose. Issuance of an eligibility letter is not a prerequisite or requirement for state 

transportation agencies seeking to use Federal-aid funds for roadside safety devices. State 

agencies may use a device for which an eligibility letter has not been issued and seek Federal-aid 

reimbursement. 

FEDERAL-AID REIMBURSEMENT

The request for issuance of this letter certified the device was crash tested in accordance with the 

industry standard of AASHTO’s MASH. This eligibility letter is based on that certification and 

the material offered in support of its issuance. The device described below is eligible for 

reimbursement under the Federal-aid highway program. 

March 8, 2023

Name of system: VORTEQ M

Type of system: Truck-Mounted Attenuator 

Test Level: Test Level 3

Testing conducted by: Applus IDIADA KARCO Engineering, LLC 

Date of request: April 21, 2022 

Information about the device, including material such as the eligibility request, crash test reports, 

drawings, or images are included in one or more attachment(s) to this letter. 

Eligibility letter CC-172 is inapplicable to devices, optional equipment, alternate materials, or 

other features that were not crash tested in accordance with AASHTO’s MASH. 

This letter is issued only for the subject device as crash tested under AASHTO’s MASH. Later 

modification(s) of the device are not eligible for Federal-aid reimbursement under this letter. 

Notice of later modification(s) should be given to transportation agencies, facility owners, and 

operators (collectively “agencies”). 

Agencies should be provided appropriate information about the device’s design, installation, 

maintenance, materials, and mechanical properties. 

Issuance of this letter is discretionary, and it may be revised or rescinded at FHWA’s discretion. 

This letter is not a determination of compliance with the Manual on Uniform Traffic Control 

Devices for Streets and Highways (MUTCD) or ownership of any intellectual property rights. 

This eligibility letter is not a determination by the government that a crash involving the subject 

device will result in any particular outcome. It is limited to only the device’s eligibility for 

Federal-aid reimbursement. 

INTELLECTUAL PROPERTY

Issuance of this eligibility letter does not convey property rights of any sort nor any exclusive 

privilege. This letter is not authorization or consent by the government for the use, manufacture, 

or sale of any patented or proprietary system, device, design, product, or hardware for which the 

requester is not the patent owner. Eligibility letters are not an expression of any view, position, 

or determination by the government as to the validity, scope, or ownership of any intellectual 

property rights to a specific device. These letters do not grant, impute, suggest, or otherwise 

establish any ownership, distribution, or licensing rights to the requester. The government 

expresses no opinion about the intellectual property rights relating to any device for which this or 

any other eligibility letter is issued. 

PUBLIC DISCLOSURE

To prevent any misunderstanding, and as discussed above, this eligibility letter is assigned 

FHWA control number CC-172. It should only be reproduced in full with its attachment(s). 

This letter and the material offered by the requester supporting its issuance is public information. 

All eligibility letters and supporting material are subject to public disclosure under the Freedom 
3 

of Information Act (FOIA). Eligibility letters are available to the public at

PRODUCT DESCRIPTION 

New Hardware or 

Significant Modification

Modification to 

Existing Hardware

The VORTEQ® M is a mobile crash cushion attached to the rear of a support vehicle. It is a towable system 

designed to be used on shadow or advanced warning vehicles upstream of moving operations or as a barrier 

vehicle for stationary work zones. The VORTEQ® M is designed to be used on support vehicles with a minimum 

weight of 12,200 lbm and no maximum weight limit. The VORTEQ® M consists of a tongue assembly, shaper 

rail assembly, x-brace assembly, impact head assembly, axle assembly, lighting, optional spare tire, and 

optional arrow board. The energy absorbing and structural portions of the VORTEQ® M consist of the tongue 

assembly, x-brace, shaper rails and impact head. The spare tire, arrow board, and battery box were present 

during testing. The tongue, x-brace and impact head assemblies are structural steel bolted together with the 

shaper rail assembly. There is also a flanged lunette ring that bolts into location on the front of the system. 

The frame is galvanized coated and has factory installed decals, name-plate, and VIN tag. 

The VORTEQ® M is 294" long by 91" wide. The system is 34" high, including the nominal height above the 

ground of 14" at the rear of the system. A system without the optional arrow board weighs approximately 

1690 lbs. The axle is a torsion axle with hubs fitted with 14” trailer wheels and tires. The axle fastens to the 

bottom of the left and right impact collars in four locations using 5/8-11 bolts and nuts. The wheels and tires 

are shrouded by fenders. There are four energy absorbing shaper rails (two per side) that are steel tube-intube design that deform during an impact event absorbing energy. Standard lighting consists of LED stop, 

turn, tail, and clearance/marker lights. The aluminum impact face plate is a light-weight assembly designed to 

cover the rear of the system and improve driver visibility. The VORTEQ® M was tested wit a painted and striped 

impact face plate. 

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.
