Trailer Truck Mounted Attenuator (TTMA)
Trailer Truck Mounted Attenuators, or crash cushions, are designed to reduce the impact of rear ends, keeping the vehicle safe during collisions. They protect motorists and workers in both moving shadow vehicle and stationary barrier vehicle applications.
The Trailer Truck Mounted Attenuator is the trailer mounted version that provides safety for people in the work zone as well as for the drivers. TMAs are designed to absorb collision energy during rear-end impacts and prevent impacting vehicles from under-riding the truck.
