**Executive Summary**
The Ministry of Road Transport and Highways (MoRTH) has initiated the deployment of advanced Truck Mounted Attenuators (TMAs) to enhance safety for workers and road users on Indian highways. As of April 21, 2026, a concessionaire has implemented 48 units across 9 National Highway projects in Andhra Pradesh and Gujarat, covering 681 kilometers. These systems aim to reduce collision severity in high-risk maintenance zones by aligning domestic infrastructure with global safety standards.
**Key Points / Main Content**
**Technology and Functionality**
* Truck Mounted Attenuators (TMAs) are impact-absorbing safety devices designed to dissipate kinetic energy during a collision.
* The systems are equipped with high-intensity "wig-wag" warning lights that flash alternating patterns and directional arrows to alert oncoming drivers.
* TMAs protect maintenance crews working ahead of the vehicle and minimize injury risks for the occupants of impacting vehicles.
**Technical Standards and Deployment**
* All units comply with global safety standards, specifically MASH Test Level-3 (TL-3) and NCHRP 350 Test Level-3.
* The systems are engineered to withstand vehicle impacts at speeds of up to 100 km/h.
* A total of 33 TMAs and 15 Towable Truck Mounted Attenuators (TTMAs) have been deployed across the selected project sections.
**Operational Benefits**
* The technology is specifically designed for high-speed highway corridors and nighttime operations.
* The warning systems provide critical early alerts to drivers during foggy or low-visibility conditions to prevent collisions before they occur.
* The initiative transforms MoRTH’s safety vision into measurable ground-level action across 681 kilometers of highway.
**Impact Analysis**
**Ministry of Road Transport and Highways (MoRTH)**
**Impact**
The deployment fulfills the Ministry's vision of bringing national highway safety standards to a global level while managing the risks associated with rapid infrastructure expansion.
**Action Required**
Continue to encourage and oversee concessionaires in the adoption of advanced safety interventions across all National Highway projects.
**Concessionaires**
**Impact**
Concessionaires managing the 9 projects in Andhra Pradesh and Gujarat are now responsible for integrating global best practices into their highway management operations.
**Action Required**
Proactively deploy and maintain the 33 TMAs and 15 TTMAs to ensure they meet the required safety certifications and operational standards.
**On-ground Maintenance and Construction Workers**
**Impact**
Workers operating in high-risk environments gain an "invisible shield" that protects them from speeding vehicles and limited visibility in construction zones.
**Action Required**
Utilize the protection provided by these attenuators during all high-risk highway maintenance and upgrade activities.
**Highway Users (Drivers)**
**Impact**
Drivers receive clearer, timely warnings through directional signals and benefit from reduced accident severity in the event of a collision with a work zone.
**Action Required**
Follow the directional cues provided by the wig-wag warning systems and maintain awareness when approaching maintenance zones on high-speed corridors.

Truck Technology Is Protecting Workers and
Road Users on Indian Highways
Posted On: 21 APR 2026 4:42PM by PIB Delhi
As the Ministry of Road Transport and Highways (MoRTH) actively expands National Highways, its
focus is not just on faster connectivity but equally on bringing safety standards to a global level.
Infrastructure development today is not only about building wider roads; it is about protecting every life
that travels on them. With this vision, advanced safety systems like Truck Mounted Attenuators (TMAs)
have been deployed on many sections of the highways, and these global practices are saving many lives,
including those of on-ground workers and highway users.
Protecting Those Who Work on the Roads
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.
To reduce these risks, MoRTH has consistently encouraged concessionaires to adopt advanced safety
interventions across highway projects. Responding to this vision, one of the concessionaires has started
taking a proactive step by deploying Truck Mounted Attenuators with integrated wig-wag warning
systems.
This concessionaire operates and manages 9 National Highway projects spanning a cumulative length of
681 kilometres across Andhra Pradesh and Gujarat, making this deployment a significant milestone in
highway safety management.
What is Truck Mounted Attenuators?
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.
This helps:
Protect maintenance crews working ahead of the vehicle
Reduce injury risks for occupants of the impacting vehicle
Minimize the severity of accidents in highway work zones
In many ways, TMAs act like an invisible shield — standing between danger and human life.
Early Warnings That Prevent Accidents
The deployed TMAs are equipped with 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.This feature is especially valuable:
On high-speed highway corridors
During night-time operations
In foggy or low-visibility conditions
By alerting drivers well in advance, these systems help prevent collisions before they occur.
Figures With a Purpose: Building Safer Highways
Across the 9 highway projects:
33 Truck Mounted Attenuators (TMAs) have been deployed
15 Towable Truck Mounted Attenuators (TTMAs) have been installed
All units comply with globally recognized 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/h
Turning Vision into Action on the Ground
This initiative reflects how MoRTH’s forward-looking safety vision is being transformed into real,
measurable action on the ground. The commitment shown by the ministry and its concessionaire
highlights the critical role they play in implementing global best practices and ensuring safer highways.
As India’s highways continue to grow wider and faster, it is equally important that safety grows stronger
with every kilometre added. Solutions like Truck Mounted Attenuators represent the evolving identity of
modern infrastructure — where development is not defined by speed alone, but by safe journeys, protected
workers, and lives saved.*****
