Limitaon and Warnings
TrafFix Devices Inc. (TDI), in compliance with the Manual for Assessing Safety Hardware
(MASH) recommended procedures for the Safety Performance of Highway Features. TDI
contracts with ISO accredited testing facilities to conduct crash tests, evaluation of tests, and
submittal of results to the Federal Highway Administration for Eligibility for Federal-Aid
Reimbursement. The Scorpion II Truck Mounted Attenuator (TMA) system was tested to meet
the safety evaluation guidelines of MASH. The Scorpion II has been tested at TL-3 (62.1 mph/
100 km/hr) speed impact conditions. These tests are intended to evaluate product performance
by simulating those impacts outlined by MASH involving a range of vehicles on the roadways,
from cars with an approx. weight of 2425 lbs [1100 kg] to trucks with an approx. weight of
5004 lbs [2270 kg]. The Model C TMA is a TL-3 tested device capable of decelerating and
stopping the light and heavy weight vehicles 2425 lbs [1100 kg] and 5004 lbs [2270 kg] in
accordance with the criteria of Tests 3-50, 3-51, 3-52, and 3-53 for TL-3 (62.1 mph/ 100 km/
hr) FHWA Eligibility. Reference FHWA Eligibility letter CC-132. Additionally, the Scorpion II
TMA was tested to meet the requirements of TD 49/07. These tests are based on the Requirements for
Lorry Mounted Crash Cushions from the Highways England Road Ministry. The Scorpion II TMA is
accepted for various speed levels as shown in TL3.UK: 110 km/h [68.3 mph]. These specified tests
are not intended to represent the systems performance 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 and TD 49 UK. TrafFix Devices does not represent nor warrant that the
results of these controlled tests show that vehicle impacts with the products in other conditions
would necessarily avoid injury to person(s) or property. Impacts that exceed the system’s
specifications may not result in acceptable crash performance as outlined in MASH; relative to
structural adequacy, occupant risk, and vehicle trajectory. TDI expressly disclaims any warrant
or liability for injury or damage to person(s) 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 installed by third parties. The Scorpion II
TMA system is intended to be assembled, delineated, and maintained in accordance with
specific State and Federal guidelines. TDI offers a reflective delineator panel for its TMA line
of products. However, the material is only intended to supplement delineation required by the
Department of Transportation’s “Manual on Uniform Traffic Control Devices” (MUTCD). The
appropriate highway authority approved engineer should be careful to properly select,
assemble, and maintain the product. Careful evaluation of the speed, traffic direction, and
visibility are some of the elements that require evaluation for the proper selection of a safety
appurtenance by the appropriate specifying highway authority.
