Rimburgerweg 40, 647 XX Kerkrade 

Netherlands 

Dear Mr. Flapper: 

This letter is in response to your August 24, 2017 request for the Federal Highway 

Administration (FHWA) to review a roadside safety device, hardware, or system for eligibility 

for reimbursement under the Federal-aid highway program. On May 29, 2020, you requested 

that this submittal be modified by substituting updated testing information for test 3-11. 

Specifically, you requested that the results for original test 3-11 (Test Report 18664 conducted 

4/19/17) be replaced by updated results for test 3-11 (Test Report 18933 conducted 5/23/18). 

Test 18664 was conducted at a higher (above the maximum MASH tolerance limit) impact speed 

but considered acceptable and test 18933 was conducted within MASH tolerances for impact 

speed. This modified letter supersedes the original letter B-292 for the SafeZone MASH TL-3 

Limited Deflection Barrier and is assigned FHWA control number B-292A and is valid until a 

subsequent letter is issued by FHWA that expressly references this device. 

Decision 

The following devices are eligible, with details provided in the form which is attached as an 

integral part of this letter: 

• SafeZone MASH TL-3 Limited Deflection

Scope of this Letter 

To be found eligible for Federal-aid funding, new roadside safety devices should meet the crash 

test and evaluation criteria contained in the American Association of State Highway and 

Transportation Officials’(AASHTO) Manual for Assessing Safety Hardware (MASH). 

However, the FHWA, the Department of Transportation, and the United States Government do 

not regulate the manufacture of roadside safety devices. Eligibility for reimbursement under the 

Federal-aid highway program does not establish approval, certification or endorsement of the 

device for any particular purpose or use. 
2

This letter is not a determination by the FHWA, the Department of Transportation, or the United 

States Government that a vehicle crash involving the device will result in any particular 

outcome, nor is it a guarantee of the in-service performance of this device. Proper 

manufacturing, installation, and maintenance are required in order for this device to function as 

tested. 

This finding of eligibility is limited to the crashworthiness of the system and does not cover other 

structural features, nor conformity with the Manual on Uniform Traffic Control Devices. 

Eligibility for Reimbursement 

Based solely on a review of crash test results and certifications submitted by the manufacturer, 

and the crash test laboratory, FHWA agrees that 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). Therefore, the device is eligible for 

reimbursement under the Federal-aid highway program if installed under the range of tested 

conditions. 

 Name of system: SafeZone MASH TL-3 Limited Deflection 

 Type of system: Rigid/Semi-Rigid Barriers 

 Test Level: MASH Test Level 3 

 Testing conducted by: Crashtest-service.com GmbH 

 Date of request: April 29, 2020 

FHWA concurs with the recommendation of the accredited crash testing laboratory as stated 

within the attached form. 

Full Description of the Eligible Device 

The device and supporting documentation, including reports of the crash tests or other testing 

done, videos of any crash testing, and/or drawings of the device, are described in the attached 

form. 

Notice 

This eligibility letter is issued for the subject device as tested. Modifications made to the device 

are not covered by this letter and will need to be tested in accordance with all recommended tests 

in AASHTO’s MASH as part of a new and separate submittal.

You are expected to supply potential users with sufficient information on design, installation and 

maintenance 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 AASHTO’s MASH.

Issuance of this letter does not convey property rights of any sort or any exclusive privilege. This 

letter is based on the premise that information and reports submitted by you are accurate and 

correct. We reserve the right to modify or revoke this letter if: (1) there are any inaccuracies in 

the information submitted in support of your request for this letter, (2) the qualification testing 

was flawed, (3) in-service performance or other information reveals safety problems, (4) the 

system is significantly different from the version that was crash tested, or (5) any other 

information indicates that the letter was issued in error or otherwise does not reflect full and 

complete information about the crashworthiness of the system. 

Standard Provisions

• To prevent misunderstanding by others, this letter of eligibility designated as FHWA 

control number B-292A 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 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. 

• This FHWA eligibility letter is not an expression of any Agency view, position, or 

determination of validity, scope, or ownership of any intellectual property rights to a 

specific device or design. Further, this letter does not impute any distribution or licensing 

rights to the requester. This FHWA eligibility letter determination is made based solely 

on the crash-testing information submitted by the requester. The FHWA reserves the 

right to review and revoke an earlier eligibility determination after receipt of subsequent 

information related to crash testing. 

Sincerely,

PRODUCT DESCRIPTION 

New Hardware or 

Significant Modification 

Modification to 

Existing Hardware 

SafeZone system isa proprietary modular high containment and low deflection steel barrier developed by 

Laura Metaal Road Safety. It is designed for both permanent and temporary use in construction and roadwork 

applications. The system is typically deployed in 5.8 m (19’) standard sections that can quickly be connected 

together to form the desired total length of barrier wall. 

Joining of the sections isdone by linking them together and applying one security bolt per section to keep the 

sections securely fastened. If desired, two or three sections can remain connected permanently to form 11.6 m 

(38’) or 17.4 m (54’) combined sections for quicker placement on the road. 

SafeZone is 0.81 m (32”) high and 0.45 m (18”) wide without anchor units or 0.64 m (25”) with anchor units. The 

weight isapproximately 93 kg/m or 62lbs/ft. For the MASH TL-3 Limited Deflection setup, 7 standard sections 

were lined up on asphalt, forming a 40.6 m (133 ft) string. The anchor positions used were the two outer 

positions, the second position on element one and the second position on every second element thereafter. 

Threaded rods 0.30 m (11.8”) long and 0.030 m (1.18”) diameter were used. All anchors were epoxied in asphalt. 

The dynamic deflection of the MASH TL3-11 test was 0.61 m (23.8”)and the permanent deflection was 0.25 m 

(9.8”). The dynamic working width was 1.06 m (41.8”)and the permanent working width was 0.65 m (25.6”).

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 testsare necessary to determine the device meets 

the MASH criteria.
