Dear Mr. Pasakarnis: 

We received your correspondence of December 23, 2021 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 WZ-433. 

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.

Name of system: STF1240 Sign Stand w/ 48in x 48in roll-up sign 

Type of system: Work Zone 

Test Level: TL-3 

Testing conducted by: Applus IDIADA KARCO Engineering 

Date of request: December 23, 2021 

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 WZ-433 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 WZ-433. 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 

2 
of Information Act (FOIA). Eligibility letters are available to the public at

Product Description of STF1240 with 48" x 48" Roll-Up Sign 

(Reference Drawing: STF1240) 

The STF1240 is a work-zone traffic control device used to display traffic control signs. 

Further Description: 

The DICKE Safety Products STF1240 device utilized a 48.0 in. (1.2 m) square vinyl roll-up sign mounted at a 

height of 18 in. (457 mm) measured to the bottom corner of the sign. The device has a total weight of 41.0 lbs 

(18.6 kg). The STF1240 sign stand consists of a telescoping mast and base assembly. The telescoping mast 

consists of a top mast and bottom mast. The top mast is constructed of 1.00 in. (25 mm) aluminum tube and 

the bottom mast is constructed of 1.25 in. (32 mm) square aluminum tube. The vinyl roll-up sign is mounted to 

the mast via a fiberglass cross brace constructed of 1.25 in. (32 mm) wide fiberglass. The mast is mounted to 

the base assembly via two (2) 0.38 in. (10 mm) diameter bolts and nuts. The base assembly consists of a base 

top, and four (4) steel legs. The four (4) steel legs are constructed of square steel tubing with a dual upright 

spring system. In the deployed state, the legs have a footprint that measures 73 in. (1.9 m) by 51.0 in. (1.3 m).

Results 

3-71 (1100C) 

An 1100C test vehicle approached the test 

article at a nominal speed of 62 mph. The 

first STF1240 with 48" x 48" roll-up sign 

device was oriented at 0° and was impacted 

at a velocity of 63.49 mph (102.17 km/h). 

Upon impact, the STF1240 deformed in a 

predictable manner and the occupant 

compartment was not penetrated. The 

deformations 0.0 in. (0 mm) were within 

MASH limits. The second device was 

oriented at 90° and was impacted at a 

velocity of 60.72 mph (97.72 km/h). Upon 

impact, the STF1240 deformed however, 

the occupant compartment was not 

penetrated and the deformations 0.0 in. (0 

mm) were within MASH limits. The STF1240

with 48" x 48" roll-up sign met all the

requirements for MASH Test 3-71.

PASS 

3-72 (2270P) 

An 2270P test vehicle approached the test 

article at a nominal speed of 62 mph. The 

first STF1240 with 48" x 48" roll-up sign 

device was oriented at 0° and was impacted 

at a velocity of 64.05 mph (103.10 km/h). 

Upon impact, the STF1240 deformed 

however, did not yield. The occupant 

compartment was not penetrated and the 

deformations 0.0 in. (0 mm) were within 

MASH limits. The second device was 

oriented at 90° and was impacted at a 

velocity of 62.50 mph (100.59 km/h). Upon 

impact, the STF1240 sign deformed 

however, did not yield. The roll-up did 

detach from the sign holder however, the 

occupant compartment was not penetrated 

and the deformations 0.0 in. (0 mm) were 

within MASH limits. The STF1240 with 48" x 

48" roll-up sign met all the requirements for 

MASH Test 3-72.
