Dear Mr. Smith:
This letter is in response to your request for the Federal Highway Administration (FHWA) to
review a roadside safety system for eligibility for reimbursement under the Federal-aid highway
|Name of system:
||Trinity SOFT-STOP Terminal for line posts with 8" wood offset blocks and a 1-foot offset from tangent (flare rate of 50:1 )|
|Type of system:
||W-Beam Guardrail Terminal|
||MASH Test Level 2 (TL-2)|
|Testing conducted by:
||Original testing by Texas Transportation Institute|
|Task Force 13 Designator:
|Date of request:
||November 1, 2012
Date initially acknowledged:
||November 1, 2012
The following device is eligible, with details provided in the form which is attached as an
integral part of this letter:
- Trinity TL3 SOFT-STOP Terminal
- 12-inch wood block-out as per eligibility letter CC-115 dated December 9, 2011
- 8-inch wood block out for both line posts and post no 2 within the Trinity Soft
Stop Terminal system, including an offset 1-foot from tangent at a flare
rate of 50:1 as per Eligibility Letter dated September 7, 2012
Based on a review of previous crash tests submitted by the manufacturer certifying the device
described herein meets the crash test and evaluation criteria of the American Association of State
Highway and Transportation Officials’ Manual for Assessing Safety Hardware (MASH), the
device is eligible for reimbursement under the Federal-aid highway program. Eligibility for
reimbursement under the Federal-aid highway program does not establish approval or
endorsement by the FHWA for any particular purpose or use.
The FHWA, the Department of Transportation, and the United States Government do not endorse products or services and the issuance of a reimbursement eligibility letter is not an endorsement of any product or service.
To be found eligible for Federal-aid funding, roadside safety devices should meet the crash test
and evaluation criteria contained in the American Association of State Highway and
Transportation Officials’ Manual for Assessing Safety Hardware (MASH).
The device and supporting documentation are described in the attached form.
Summary and Standard Provisions
Therefore, the system described and detailed in the attached form is eligible for reimbursement
and may be installed under the range of conditions tested.
Please note the following standard provisions that apply to FHWA eligibility letters:
- This letter provides a AASHTO/ARTBA/AGC Task Force 13 designator that
should be used for the purpose of the creation of a new and/or the update of existing
Task Force 13 drawing for posting on the on-line ‘Guide to Standardized Highway
Barrier Hardware’ currently referenced in AASHTO Roadside Design Guide.
- This finding of eligibility does not cover other structural features of the systems,
nor conformity with the Manual on Uniform Traffic Control Devices
- Any changes that may influence system conformance with MASH will require a
new reimbursement eligibility letter.
- Should the FHWA discover that the qualification testing was flawed, that in-service
performance reveals safety problems, or that the system is significantly different
from the version that was crash tested, we reserve the right to modify or revoke this
- You are expected to supply potential users with sufficient information on design
and installation 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 the MASH
- To prevent misunderstanding by others, this letter of eligibility is designated as
number CC-115B and 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 at our office upon request.
- 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. The FHWA does not become involved in issues concerning patent law.
Patent issues, if any, are to be resolved by the applicant.
- The Trinity SOFT-STOP Terminal is a patented product and considered proprietary.
- If proprietary systems are specified by a highway agency for use on Federal-aid
projects: (a) they must be supplied through competitive bidding with equallysuitable unpatented items; (b) the highway agency must certify that they are
essential for synchronization with the existing highway facilities or that no equally
suitable alternative exists; or (c) they must be used for research or for a distinctive
type of construction on relatively short sections of road for experimental purposes.
Our regulations concerning proprietary products are contained in Title 23, Code of
Federal Regulations, Section 635.411.
