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-423 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® 2001M 

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

The Yodock® 2001 M 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 M 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 M Longitudinal Channelizer modules are 6.0 ft. long by 18 in. wide by 32 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 75 lbs. 

empty and approximately 534 lbs. when filled to the bottom of the fork lift ports with water. When assembled 

as an LCD, the Yodock® 2001 M 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 M may be placed on concrete, asphalt, or other smooth level substrates. The surfaces used 

for testing were concrete and dirt. Alternating Yodock® 2001 M 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.
