A truck attenuator, also known as a crash mounted attenuator or TMA truck, is an essential safety vehicle used to protect road workers, equipment and motorists in high-risk environments like highway maintenance, lane closures and emergency response zones.
These specially fitted trucks feature an energy-absorbing crash cushion on the rear, designed to reduce the impact force if a vehicle collides with it, helping to prevent serious injury or damage.
Coates’ mounted attenuator units act as a mobile crash barrier, absorbing the kinetic energy of an impact and shielding workers or work zones positioned ahead of the truck. The TMA can also serve as a platform for signage, arrow boards and traffic management equipment, helping to alert and guide approaching motorists.
Hire a truck-mounted attenuator today from Coates, a vital part of any safe traffic management plan.
TMA trucks aren’t mandatory on all roadwork sites, but they are often required for high-speed or high-risk areas, such as highways or major arterial roads. Their use is typically guided by state regulations and traffic management plans, which assess risk levels and determine when impact protection is essential for crew safety.
Yes, our truck-mounted attenuator hire is designed for use on both day and night shifts. They feature high-visibility markings, reflective panels and arrow boards or lighting systems, ensuring they remain clearly visible in low-light conditions. This makes them ideal for 24/7 roadwork operations where safety and visibility are critical.
Yes, in Australia, you generally need a heavy vehicle licence (typically an HR licence) to operate a TMA truck. Licence requirements can vary by state and vehicle size, so it’s important to check local regulations before operating a truck-mounted attenuator that you hire on-site.
