The Ministry of Road Transport and Highways has encouraged the deployment of Truck Mounted Attenuators with integrated wig-wag warning systems across nine National Highway projects spanning 681 kilometres in Andhra Pradesh and Gujarat
Truck Mounted Attenuators are impact-absorbing safety devices designed to protect highway maintenance workers and road users in the event of a collision. When struck, the systems absorb and dissipate kinetic energy, shielding crews working ahead of the vehicle and reducing injury risk for occupants of the impacting vehicle.
The deployed units are equipped with high-intensity wig-wag warning lights that flash in alternating directional arrow patterns, providing advance warning to approaching drivers, particularly on high-speed corridors, during night operations, and in low-visibility conditions.
Across the nine highway projects, 33 Truck Mounted Attenuators and 15 Towable Truck Mounted Attenuators have been installed. All units comply with globally recognised safety standards including MASH Test Level-3 and NCHRP 350 Test Level-3, and are designed to withstand impacts at speeds of up to 100 kilometres per hour.
