TURNING WORK ZONES INTO SAFE ZONES

摘要

here has to be a better way of keeping road crews safe than putting them in harm's way. Truck-mounted attenuators (TMAs) attach to the back of a work truck to absorb the impact when a distracted driver, despite all warnings that construction lies ahead, plows his car or truck full-speed into the work zone. The TMA trucks job is to follow a vehicle that's placing material and/or equipment and cushion the blow. The first truck is the leader truck; the second, the shadow truck.
