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

Reimbursement. The Scorpion II Metro Truck Mounted Attenuator (TMA) system was tested
to meet the safety evaluation guidelines of MASH.
The Scorpion II Metro has been tested at
TL - 2 PLUS (50 mph/80 km/hr) speed 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 Scorpion II Metro TMA is a TL
- 2 PLUS tested
device is capable of decelerating and stopping light and heavy weight vehicles 2425 lbs [1100
kg] and 5004 lbs [2270 kg] in accordance with the criteria of Tests 2
- 50, 2 - 51, 2 - 52, and 2 - 53
for FHWA Eligibility (Reference FHWA Eligibility Letter CC - 158). 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 Metro TMA system is intended to be assembled, 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.
