An attenuator truck, also referred to as an impact truck or a crash truck, is a vehicle designed to reduce the risks of injury and protect the lives of construction workers and motorists. These specially designed trucks serve as protective devices meant to absorb the kinetic impact resulting from motor vehicle collisions. Attenuator trucks are most often found in front of temporary or fixed structures on highways, such as road construction projects, gore points, overpass supports, or crash barriers.

The main idea of truck-mounted crash attenuators is to create a crumple buffer zone that absorbs the kinetic energy from a crash. The device itself consists of cartridge and strut sections that are connected on a single support frame. Our attenuator trucks also feature curved aluminum side rails that provide full-width protection and redirect incoming vehicles from the truck. At Curry Supply, we offer high-performance trucks equipped with cutting edge TrafFix Scorpion® TMA Model TL-3 attenuators. These devices have passed all the necessary impact tests and inspections, including a “worst case” side-angle redirective impact testing and all the mandatory and optional requirements recommended in the NCHRP-350 Report.

Crash attenuator trucks are a must for any company, municipality, or governing body looking for a way to protect roadside workers and the driving public. They offer reliable protection from low and high-speed crashes, minimizing the chances of serious injuries and expensive machinery damage.

Without an attenuator truck present, a vehicle collision could easily result in injuries that may threaten the lives of the driver and/or construction workers. An attenuator truck can help prevent such severe injuries by dissipating the kinetic energy of the vehicle and redirecting it from the construction machinery and the workers.

Truck-mounted crash attenuators can offer protection for both temporary and fixed roadside structures, such as:

• Road construction projects

• Crash barriers

• Bridge parapets

• Toll gates

• Guard rails

• Overpass supports

• Gore points, etc.

Attenuator devices are typically mounted on the back of the crash attenuator truck, or placed on other vehicles that are prone to being hit from behind, such as maintenance and road construction vehicles, snowplows and the like.
