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

3-71 (1100C)

An 1100C test vehicle approached the test 

article at a nominal speed of 62 mph (100 

km/h). The DL1008 with 48" x 48" Roll-Up 

Sign impact was oriented at 0° and 90°. The 

test vehicle impacted the 0° CIA device at a 

speed of 62.38 mph (100.39 km/h). The 

vehicle’s wheels first contacted the DL1008 

legs. The vehicle’s bumper then contacted 

the DL1008 stand’s base assembly. As the 

vehicle proceeded forward the upper mast 

began to deform around the vehicle’s 

bumper and the 48” x 48” roll-up sign 

impacted the hood and windshield. The 

occupant compartment was not penetrated 

and the deformations 0.0 in. (0 mm) were 

within MASH limits. The test vehicle 

impacted the 90° CIA device at a velocity of 

60.02 mph (96.59 km/h). The vehicle first 

contacted the 48” x 48” roll-up sign followed 

by the base assembly. The base assembly 

deformed around the vehicle’s bumper and 

was stuck to the vehicle’s front end as the 

vehicle proceeded forward. The sign 

remained intact throughout the impact. The

occupant compartment was not penetrated 

and the deformations 0.0 in. (0 mm) were 

within MASH limits. The DL1008 with 48" x 

48" Roll-Up Sign met all the requirements 

for MASH Test 3-71.

3-72 (2270P)

A 2270P test vehicle approached the test 

article at a nominal speed of 62 mph (100 

km/h). The DL1008 with 48" x 48" Roll-Up 

Sign impact was oriented at 0° and 90°. The 

test vehicle impacted the 0° CIA device at a 

velocity of 64.34 mph (103.55 km/h). Upon 

impact, the base assembly deformed 

around the vehicle’s bumper as the left 

front wheel drove over one of the sign 

stand’s legs. The sign stand’s bottom mast 

and base assembly yielded. The bottom 

mast then broke away completely from the 

base assembly. The 48" x 48" roll-up sign 

impacted and stuck to the vehicles grill and 

hood as the vehicle proceeded forward. The 

occupant compartment was not penetrated 

and the deformations 0.0 in. (0 mm) were 

within MASH limits. The test vehicle 

impacted the 90° CIA device at a velocity of 

62.88 mph (101.19 km/h). The vehicle first 

contacted the 48” x 48” roll-up sign 

followed by the base assembly. The sign 

stand deformed around the vehicle and was 

stuck to the front end as the vehicle 

proceeded forward. The sign remained 

mostly intact throughout the impact event 

with only one leg detaching from the base 

assembly. The occupant compartment was 

not penetrated and the deformations 0.0 in. 

(0 mm) were within MASH limits. The 

DL1008 with 48" x 48" Roll-Up Sign met all 

the requirements for MASH Test 3-72.
