Dear Mr. Eckert: 

This letter is in response to your October 26, 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-422 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: 

• YODOCK® 2001 

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.

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: YODOCK® 2001 

Type of system: Longitudinal Channelizer 

Test Level: MASH Test Level 3 (TL3) 

Testing conducted by: Applus IDIADA KARCO Engineering, LLC. 

Date of request: October 26, 2020 

FHWA concurs with the recommendation of the accredited crash testing laboratory on 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. 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 

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 WZ-422 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.

The Yodock® 2001 Longitudinal Channelizer is a plastic, water-filled Longitudinal Channelizing Device (LCD) 

used for traffic and pedestrian channelization, road and street closures, or perimeter fencing for vertical 

construction. The Yodock® 2001 is not designed as a positive barrier; rather, it is meant to provide a clear 

visual indication of the intended vehicle path through construction zones. When assembled as an LCD, the 

units are attached end-to-end using a plastic coupler and deployed with the water fill level at the bottom of 

the forklift ports. 

The Yodock® 2001 Longitudinal Channelizer modules are 6.0 ft. long by 24 in. wide by 46 in tall. The modules 

are manufactured from natural and orange colored high density polyethylene plastic. Orange and white were 

the as-tested colors, the product may be produced in other colors. The modules weigh approximately 130 lbs. 

empty and approximately 750 lbs. when filled to the bottom of the fork lift ports with water. When assembled 

as an LCD, the Yodock® 2001 modules are attached end-to-end using a plastic coupler. The modules 

incorporate fork lift access ports for maneuverability and features for vertical stacking during transport and 

storage. 

The Yodock® 2001 may be placed on concrete, asphalt, or other smooth level substrates. The surfaces used for 

testing were concrete and dirt. Alternate Yodock® 2001 modules within the impact region in the attached test 

reports were tested with hazard lights. 

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.
