An attenuator is a crash cushion mounted to a truck’s rear. This type of truck is called an Attenuator Truck or sometimes a Crash Truck. These trucks can be seen in roadway work zones to protect workers from moving traffic. The attenuator absorbs impact when hit by a vehicle.
A ballast box is typically an empty metal box at the front of the bed. The box is used to provide the counterweight needed for proper usage of the attenuator based on state regulations. It is usually filled with heavy materials such as gravel or sand.
TMA stands for Truck Mounted Attenuator.
