Truck-Mounted Attenuators Deployed on Highways to Protect Workers & Drivers

Infrastructure development in India prioritises the protection of every motorists and worker, and adopting this vision, one concessionaire has installed the systems with integrated wig‑wag warning systems, an official statement said.

These high-intensity wig-wag warning lights, designed to flash in alternating patterns that form directional arrows. These signals provide clear and timely warnings to approaching drivers.

The statement from Ministry of Road Transport & Highways said that 33 Truck Mounted Attenuators and 15 Towable Truck Mounted Attenuators have been deployed, all meeting global safety standards including MASH Test Level‑3 (TL‑3) and NCHRP 350 Test Level‑3.

These systems are designed to withstand impacts at speeds of up to 100 km per hour, the statement noted.

"Behind every highway upgrade and maintenance activity are hundreds of workers who operate in challenging and high-risk environments. Maintenance and construction zones on busy highways are among the most vulnerable areas, where speeding vehicles and limited visibility can lead to severe accidents," the ministry said.

To reduce these risks, MoRTH has consistently encouraged concessionaires to adopt advanced safety interventions across highway projects, and one of the concessionaires responded with this proactive step, the ministry said.

Truck Mounted Attenuators are specially designed impact-absorbing safety devices that play a critical role in protecting both workers and road users. In the event of a collision, these systems absorb and dissipate kinetic energy, reducing the force of impact.

"The commitment shown by the ministry and its concessionaire highlights the critical role they play in implementing global best practices and ensuring safer highways," the statement noted.
