TrinityHighway.com 5 Revision D March 2021

Limitations and Warnings

Trinity Highway contracts with independent crash testing facilities to test and prepare a crash test

report for FHWA review.

The QuadGuard® M Wide has been deemed eligible for reimbursement by the FHWA per

AASHTO requirements and guidelines of MASH. These tests evaluate product performance

defined by AASHTO involving lightweight cars (approx. 2420 lb. [1100 kg]) and full size pickup

trucks (approx. 5000 lb. [2270 kg]). A product can be certified for multiple Test Levels. The

QuadGuard® M Wide is certified to the Test Level(s) as shown below:

Test Level 3: 62 mph [100 kph]

These AASHTO directed tests are not intended to represent the performance of systems

when impacted by every vehicle type or every impact condition existing on the roadway.

This system is tested only to the test matrix criteria of MASH as approved by FHWA.

Trinity Highway expressly disclaims any warranty or liability for injury or damage to persons or

property resulting from any impact, collision or harmful contact with products, other vehicles, or

nearby hazards or objects by any vehicle, object or person, whether or not the products were

assembled in consultation with Trinity Highway or by third parties.

The QuadGuard® M Wide is intended to be assembled, delineated, and maintained within specific

state and federal guidelines. It is important for the highway authority specifying the use of a

highway product to select the most appropriate product configuration for site specifications. The

customer should be careful to properly select, assemble, and maintain the product. Careful

evaluation of site layout, traffic speed/type, direction, and visibility are some of the elements that

require evaluation by the highway authority in the selection of a highway product. For example,

curbs could cause an untested effect on an impacting vehicle.

After an impact occurs, the debris from the impact should be removed from the area immediately

and the specified highway product should be evaluated and restored to its original specified

condition or replaced as the highway authority determines as soon as possible.

Warning: Do not assemble, maintain, or repair the QuadGuard® M Wide until you

have read this manual thoroughly and completely understand it. Please contact

Trinity Highway if you do not understand these instructions (p. 3).

Warning: It is the responsibility of the installer to ensure that all Danger, Warning,

Caution, and Important statements within the QuadGuard® M Wide manual are

completely followed. Failure to follow this warning could result in serious injury or

death in the event of a collision.

TrinityHighway.com 6 Revision D March 2021

System Overview

The QuadGuard® M Wide is a re-directive, non-gating crash cushion for roadside features of

69” [1753 mm] or less in width with use of approved transitions. It consists of energy-absorbing

cartridges surrounded by a framework of Quad-Beam Fender Panels.

Important: Trinity Highway makes no recommendation whether use or

reuse of any part of the system is appropriate or acceptable following an

impact. It is the sole responsibility of the project engineer and/or the local

highway authority and its engineers to make that determination. It is critical

that you inspect this product after assembly is complete to make certain that

the instructions provided in this manual have been strictly followed.

The QuadGuard® M Wide utilizes two types of cartridges in a “staged” configuration that are

designed and tested to address vehicles as defined by MASH for both lighter cars and heavier,

high center-of-gravity vehicles.

Impact Performance

The six (6) Bay QuadGuard® M Wide has successfully passed the requirements stipulated in

MASH with both the light car and pickup trucks at speeds of up to 62 mph [100 kph] at redirection

angles up to 25 degrees.

During head-on impact testing, within MASH criteria, the QuadGuard® M Wide has been shown

to telescope rearward to absorb the energy of impact. When impacted from the side, within the

applicable MASH criteria, it has been shown to redirect the vehicle back toward its original travel

path and away from the highway feature.

Warning: It is the sole responsibility of the project engineer and/or local highway

authority and its engineer to ensure that the QuadGuard® M Wide and delineation

used meet all federal, state, specifying agency, and local specifications.

Warning: It is the sole responsibility of the project engineer and/or local highway

authority and its engineer to ensure that the QuadGuard® M Wide meets all

appropriate Manual on Uniform Traffic Control Devices (“MUTCD”) and local

standards.

Inspect Shipping

Check the received parts against the shipping list supplied with the system before deploying the

QuadGuard® M Wide. Make sure all parts have been received (pp. 40 - 41).

Important: The Manufacturer’s Drawing Package supplied with the QuadGuard®

M Wide must be used with these instructions for proper assembly and should take

precedence over these general instructions.

Warning: Do NOT modify the QuadGuard® M Wide in any way.
