The Ministry of Road Transport and Highways (MoRTH) is pushing the adoption of advanced safety systems, including Truck Mounted Attenuators (TMAs), across National Highways as part of its broader effort to align infrastructure development with global safety standards, with on-ground deployment being carried out by concessionaires.
According to a statement by the ministry on Tuesday, 21 April, the initiative focuses not only on improving connectivity but also on enhancing safety for both highway users and on-ground workers operating in high-risk construction and maintenance zones.
As part of its highway safety push, MoRTH has been urging concessionaires to adopt advanced protection measures in construction and maintenance zones.
In line with that approach, one concessionaire has deployed Truck Mounted Attenuators fitted with integrated wig-wag warning systems, the ministry said.

The concessionaire manages 9 National Highway projects covering 681 Km across Andhra Pradesh and Gujarat.
The deployment marks a notable step in strengthening safety management across these stretches.
As part of this rollout, 33 TMAs and 15 towable TMAs (TTMAs) have been installed.
TMAs are impact-absorbing devices designed to reduce the severity of collisions in work zones.
In the event of a crash, these systems absorb and dissipate kinetic energy, thereby protecting maintenance crews ahead of the vehicle and reducing injury risks for occupants of the impacting vehicle.
The deployed systems are equipped with high-intensity wig-wag warning lights that flash in alternating patterns to guide approaching drivers.
These visual signals are particularly effective on high-speed corridors and during low-visibility conditions such as night operations or fog.
MoRTH stated that all deployed units comply with internationally 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 kmph.
The ministry said the initiative reflects its emphasis on improving safety standards alongside highway expansion, with a focus on protecting workers and road users through the adoption of globally recognised practices.
