Why use a Scorpion Attenuator Distributor?
At the heart of Royal’s mission is safety first; and that’s why we’re a master attenuator distributor of the Scorpion Truck Mounted Attenuator. It’s the first MASH Tested TMA! Providing adequate and properly built or repaired protection in the form of an Attenuator Crash Truck can be one of the most important things a company does for its workers and the driving public. Royal is the largest certified installation and repair facility for the TrafFix Devices Scorpion Attenuator in the United States, installing and repairing hundreds of TMAs every year.

According to MUTCD standards, Attenuators are to be installed and used in accordance with manufacturer’s specifications and requirements. Any repair or installation of a Scorpion Attenuator must be done by an approved and certified installer to be considered “crash-worthy”, and in compliance with MUTCD for use in the United States.

Royal is not only certified attenuator distributor, but is also a training facility for hands-on experience on how to operate a TMA Truck, a Scorpion Attenuator, and many other traffic safety related products. Contact Us for all your TMA truck needs!

Your Truck Mounted Attenuator Must Be a MASH Tested TMA

Key Points:

  1. All new testing will be done following MASH evaluation techniques.
  2. Hardware accepted under NCHRP Report 350 is appropriate for replacement and new installation. Retesting is not required.
  3. As of January 1, 2011, all new products must be tested using MASH
    crash test criteria for use on the National Highway System (NHS).


MASH updates and replaces NCHRP Report 350. This manual is recommended for highway design engineers, bridge engineers, safety engineers, researchers, hardware developers, crash test laboratories, and others concerned with safety features used in the highway environment. Products addressed in MASH include longitudinal barriers, transitions, end terminals, crash cushions, breakaway supports, truck mounted attenuators, and work zone traffic control devices. The crash performance is judged on structural adequacy, occupant risk, and vehicle trajectory.

Scorpion Attenuator Facts:

  • MASH updates and replaces NCHRP Report 350. As of January 1, 2011, all new products must be tested using MASH crash test criteria.
  • After your attenuator is hit, it needs to be “re-certified” before it gets back on the road.
  • If your attenuator is not installed by a certified facility, you could be adding unnecessary liability to your work zone.
  • A TMA Truck must weigh 20,000 lbs to be a MUTCD recommended “safe” TMA Truck. Your truck should withstand the g-force of a tractor trailer crash.
  • Good welding is one of the most important factors when your attenuator is attached to your truck.
  • Different attenuators have different levels of certification – Royal Truck & Equipment only installs the Scorpion Truck Mounted Attenuator on their trucks.
