Dear Mr. Gripne:

This letter is in response to your request for the Federal Highway Administration (FHWA) to review roadside safety systems for eligibility for reimbursement under the Federal-aid highway program.

Name of system: Vertical Loading Terminal (VLT)/Soft Stop with 25-foot panels
Type of system: Energy absorbing guardrail terminals
Test Level: MASH Test Level-2 and Test Level-3
Testing conducted by: Original testing by Texas Transportation Institute
Task Force 13 Designator: SEW22C
Date of request: September 3, 2013

Decision:
The following devices are eligible, with details provided in the form which is attached as an integral part of this letter:

Based on a review of the analysis 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.

Requirements
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).

Description
The device and supporting documentation are described in the attached form.  The change covered by this letter allows the use of 25-foot long w-beam guardrail panels within the limits of the VLT / Soft Stop Terminals in lieu of spliced 12-foot, 6-inch long sections. The analysis provided shows that the test vehicle would travel less than two feet further after impacting the VLT / Soft Stop heads.  This distance is still within the design length of the terminals.

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:

 

Sincerely yours,
