Limitations and Warnings
Trinity Highway, in compliance with NCHRP-350,
contracts with ISO 17025 A2LA accredited testing
laboratories to perform crash tests, evaluate tests, and
submit the test results to the FHWA for review.
The SRT™ 31 System has been deemed eligible by
FHWA as meeting the requirements and guidelines of
NCHRP Report 350, Test Level 3 (“TL-3”). These tests
typically evaluate product performance defined by
NCHRP Report 350 involving a range of vehicles on
roadways, from lightweight cars (approx. 800 kg [1800
lb.]) and full size pickup trucks (approx. 2,000 kg [4,400
lb.]) at 100 kph [62 mph].
The SRT
TM
31 System is tested pursuant to the test
matrix criteria of NCHRP Report 350 as designated
by FHWA. The FHWA 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 SRT™ 31 System is intended to be assembled,
delineated, and maintained within state/specifying
agency and federal guidelines. It is important for the
state/specifying agency specifying the use of a highway
product 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 SRT™ 31 System 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
and the state DOT.

of the SRT™ 31 System is appropriate or acceptable
after system impact. It is the responsibility of the
state/specifying agency and its engineers to make
that determination.
