Truck mounted attenuators (TMAs) are designed to protect workers adjacent to high-speed, high-traffic freeways and one-way drives. TMAs are equipped with an impact attenuating crash cushion that absorbs the impact during a collision and protects structures and equipment on the job site. This facilitates smooth traffic flow even in the event of a crash. They also reduce debris hazards after impact and protect workers, motorists, and other road users.
If you are considering renting a TMA for your project, you should consider the following factors to ensure safety in your work zone.
