Worker fatalities at roadside work zones have been steadily declining for decades, owing to the enhanced safety measures and the use of crash attenuator trucks. These vehicles rely on a variety of specialized crash truck equipment and features to protect the safety of roadside workers and machinery.

If you are looking for an attenuator truck for sale or need replacement parts, you need to choose your truck manufacturer carefully. They should be able to provide you with a custom or ready-made vehicle equipped with an appropriate truck-mounted attenuator, lighting, controls, and other useful features.

What features should my attenuator truck have?

When browsing for a crash attenuator truck, one of your main focuses should definitely be the truck-mounted attenuator itself.

Truck-Mounted Attenuator (TMA)

The attenuator is one of the core elements of a crash truck’s effectiveness. They are typically measured based on their test level (TL) rating. For example, a TL-3 attenuator is rated to stop vehicles traveling at a certain weight and speed. The Scorpion TL3’s rating is 100 km/h (62mph). This is the maximum TL rating currently available on the attenuator market. This test level, TL3, is required for highway work zones in excess of 50 mph.

TrafFix Devices’ TMA is one of the safest and most reliable on the market. Their Scorpion® TMA Model TL-3 attenuator is constructed from high-quality materials and designed to offer full-width impact protection. Additionally, this attenuator has carefully designed side rails made of corrosion resistant aluminum that help redirect errant vehicles away from the truck’s rear end. The attenuator’s moisture-proof boxes consist of an aluminum honeycomb core increasing longevity and durability.

Finally, the TrafFix Devices Scorpion® TMA Model TL-3 attenuator has been tested and passed all mandatory and optional attenuator requirements stated in the NCHRP-350 Report. In addition, The Scorpion® TMA has also successfully passed the UKTD49 test for 110 km/h.


A crash attenuator truck should have the appropriate braking system to ensure the safety of the drivers and roadside workers. Curry Supply recommends building on air brake chassis or specially altered hydraulic brake chassis.

Additional equipment

To maximize the safety offered by a crash attenuator truck, you should also look for vehicles equipped with:

  • User-friendly arrow boards with appropriate LED lights
  • Convenient control panels inside the cab for operating the attenuator
  • Shatterproof arrow board lights
  • Heavy-duty flatbed with powder coating and high-visibility accents
  • Integrated man baskets with non-slip coatings
  • Powder-coated truck body and stake sides
  • Appropriately lined deck that prevents slippage

Your truck-mounted attenuator should also meet all relevant state and federal regulations for impact, so make sure to check that with potential manufacturers before making any decisions.
