Limitations and Warnings
Trinity Highway, in compliance with MASH,
contracts with ISO 17025 A2LA accredited testing
laboratories to perform crash tests, evaluate tests,
and submit the test results to the FHWA for review.
MATT™ was tested to MASH-2nd Edition (2016), with
2020 Errata TL-3 criteria and may be used in Test Level
1, Test Level 2, and Test Level 3 applications – when
installed at the full Test Level 3 system length of 34’ 4-
1/2” [10.477 m]. These tests typically evaluate product
performance defined by MASH involving a range of
vehicles on roadways, approximately 1,100kg [2,420
lb.] and full size pickup trucks (approximately 2,270
kg [5,000 lb.] at 100 kph [62 mph].
The MATT™ is tested pursuant to the test matrix
criteria of MASH as designated by AASHTO and
FHWA. The FHWA/AASHTO tests are not
intended to represent the performance of
systems when impacted by every vehicle type or
in every impact condition existing on the
roadway. Every departure from the roadway is a
unique event.
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 its 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 MATT™ is intended to be assembled, delineated,
and maintained within
the state/specifying agency
and
federal guidelines. It is important for the
state/specifying agency to select the most appropriate
product configuration for site specifications.
The state/specifying agency’s careful evaluation of the
site layout, vehicle population type and speed, traffic
direction, and visibility are some of the elements that
require evaluation in the selection of a highway product.
For example, curbs could cause an untested effect
on an impacting vehicle.
After an impact with the system, all debris must be
removed from the area immediately in compliance with
the most applicable state/specifying agency policy. The
specified
MATT™ must be evaluated and restored to
its original specified condition or replaced as the
state/specifying agency determines/requires, as soon
as possible. Product selection, approval, proper
installation, and maintenance of any highway product is
the sole responsibility of the state/specifying agency.
WARNING: Under NO circumstances shall the rail
within the MATT™ be curved/radiused, between
Post 1 and Post 6.
All metric dimensions are “soft conversions” and
as such should be considered as reference only.
Safety Alert Symbols appear throughout this
manual and indicate Danger, Warning, Caution or
Important statements. Failure to read and follow
these warnings could result in serious injury or
death in the event of a vehicle impact with the
system.
WARNING: Do not assemble, maintain, or repair
the MATT™ until you have read this manual

WARNING: Safety measures incorporating
appropriate traffic control devices and personal
protective equipment ("PPE") specified by
the
state/specifying agency must be used to protect
all personnel while at the assembly,
maintenance, or repair site. Work gloves, apron,
eye protection, safety-toe shoes, and
back
protection shall be used.
WARNING: Ensure the assembly site meets all
appropriate Manual on Uniform Traffic Control
Devices (“MUTCD”) and the state/specifying
agency standards.
WARNING: Use only Trinity Highway parts that are
specified by Trinity Highway for use with the
MATT™ for assembling, maintaining, or repairing
the MATT
™ . Do not utilize or otherwise
commingle parts from other systems even if those
systems are other Trinity Highway Products or
Systems.
Such configurations have not been
tested, nor have they been approved for use.
Assembly,
maintenance or repairs using
unspecified parts or accessories is strictly
prohibited. Failure to follow this warning could
result in serious injury or death in the event of
a vehicle impact with such an UNACCEPTED
system.
WARNING: Do NOT modify the MATT™ in any
way.
IMPORTANT: Trinity Highway makes no
recommendation whether use or reuse of any part
of the MATT™ is appropriate or acceptable after
system impact. It is the responsibility of the
state/specifying agency
and its engineers to make
that determination.
IMPORTANT: It is the responsibility of owner,
state/specifying agency, or specifier
to inspect the
MATT™ after assembly is complete to ensure the
instructions provided in this manual have been
strictly followed.
