USA 

Dear Mr. Eckert: 

This letter is in response to your June 22, 2020 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. This FHWA letter of eligibility is assigned FHWA 

control number WZ-420 and is valid until a subsequent letter is issued by FHWA that expressly 

references this device. 

Decision 

The following device is eligible within the length-of-need, with details provided in the form 

which is attached as an integral part of this letter: 

• SiteGuide® LCD

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. 

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. 
2

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 AASHTO’s 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: SiteGuide® LCD

Type of system: Longitudinal Channelizer 

Test Level: MASH Test Level 3 (TL3) 

Testing conducted by: E-Tech Testing Services 

Date of request: June 22, 2020

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. Any modifications to this device should be submitted to the user 

(i.e., state DOT) as per their requirements. 

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

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 WZ-420 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

• 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.

PRODUCT DESCRIPTION 

A brief description of each crash test and its result: Help 

New Hardware or Modification to 

Significant Modification Existing Hardware 

The SiteGuide®LCD system is a new highly portable, water filled, American with Disabilities Act ("ADA") 

compliant, longitudinal channelizing device especially suited for use as a temporary barricade, delineator, or to 

provide a means of visual direction in highway construction zones. The SiteGuide®LCD is normally provided in 

alternating highly visible work zone safety orange and white (natural) colored sections. 

The SiteGuide®LCD barricade sections are constructed of linear low density polyethylene plastic and have 

approximate physical dimensions and capacities of length (pin to pin) 1524mm [60 in.]; width: 406.4 mm [16 

in.]; height: 841mm [33 1/8 in.]; empty weight: 22.2 kg [49 lb.]; full weight: 303.0 kg [668 lb.]; water ballast: 

281.1 liters [74.4 gallons]. The endsof each barricade section are constructed with one downward pin anda 

facing up receiver pocket which interlock with those of adjacent sections. The barricade sections have vertical 

sidewalls to interact with an impacting vehicle. They also provide an ADA hand rail and feature a flat top and 

bottom geometry such that a second and third section can neatly stack on top of the first for efficient transport 

and storage. The barricade sections also have elevated forklift openings to allow for mechanical lifting when 

empty or full, and incorporate two 114 mm [4.5 in.] diameter quick fill openings with covers, and two 38mm [1 

1/2 in.] diameter HDPE drain plugs to allow quick draining of the water ballast. 

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 tests are necessary to determine the device meets 

the MASH criteria.

The results of both MASH Test 3-90's 

conducted on the ADA and non-ADA faced 

sides of the SiteGuide®LCD barriers met all 

testing requirements. The longitidunal 

channelizers allowed the vehicles to pass

both tests was within MASH test 

specifications with damaged limited to the 

vehicle grille, bumper, hood, and fenders. 

The windshield was cracked in the lower 

driver side from contact of the hood, but 

with no windshield deformation into the 

occupant compartment. There was no 

damage to the vehicle interior.

SITEGUIDETM LONGITUDINAL CHANNELIZING DEVICE

The SiteGuideTM Longitudinal Channelizing Device (LCD) is a portable, tested, and American with

Disabilities Act (ADA) compliant, temporary barricade or delineator used to provide pedestrian

channelization and portable traffic control in highway construction zones. The SiteGuideTM LCD is

composed of individual lightweight, orange and white (natural) colored, plastic barricade sections

with the following physical dimensions and capacities; Length (pin to pin): 1524 mm [60 in.], width:

406.4 mm [16 in.], height: 813 mm [32 in.], empty weight: 22.2 kg [49 lb.], full weight: 280.8 kg

[619 lb.] and water ballast: 258.5 liters [68.3 gallons]. The barricade sections are constructed with

an interlocking downward-facing pin on one end and an up-facing receiver on the other end for

connection of adjacent sections.

The SiteGuideTM LCD was tested as a Longitudinal Channelizing Device in accordance with the

AASHTO MASH TL-3 evaluation criteria. The SiteGuideTM LCD met all requirements for

Tests 3-90 and 3-91 when impacted on both the traffic side of the barricade, and on the non-traffic,

ADA compliant, side of the barricade.
