New Radar and V2X Rules Open Door to Car Safety Tech in India

India has taken a decisive regulatory step that could significantly accelerate the deployment of advanced vehicle safety technology across the country's roads. The government has granted frequency exemptions for two critical categories of automotive communication technology — radar sensors operating in the 77 GHz to 81 GHz range, and Vehicle-to-Everything communication systems operating in the 5.9 GHz band — removing licensing barriers that have until now slowed the adoption of safety features that are already standard in vehicles across the United States and the European Union. For a country that recorded more than 1.77 lakh road fatalities in nearly five lakh accidents in 2024, the practical road safety implications of this regulatory change are significant and immediate.

Overview of India's New Radar and V2X Frequency Exemptions

Two Exemptions That Together Transform India's Vehicle Safety Landscape

The government's decision to grant licensing exemptions for two distinct but complementary frequency bands — 77 to 81 GHz for radar sensors and 5.9 GHz for V2X communication — reflects a coherent and forward-looking technology strategy for vehicle safety. These two frequency bands serve different but interconnected road safety functions: radar sensors provide vehicles with the ability to sense their immediate physical environment, while V2X communication enables vehicles to share safety information with each other and with roadside infrastructure. Together, they form the technological foundation of the connected, sensor-equipped vehicle ecosystem that road safety experts identify as one of the most promising systemic interventions available for reducing road accident fatalities at scale.

Until this exemption, automakers seeking to deploy these technologies in Indian-market vehicles faced the additional cost, complexity, and delay of navigating frequency licensing requirements — a regulatory burden that was inconsistent with the treatment of the same technologies in other major automotive markets globally. By removing this burden through exemption, the government has created immediate regulatory parity between India and the world's most advanced automotive safety markets, enabling manufacturers to bring globally developed hardware and software to India without the customisation costs and timeline extensions that market-specific licensing requirements previously imposed.

What the 77-81 GHz Radar Exemption Enables for Road Safety

Sensing the Road Environment With Precision and Reliability

Radar sensors operating in the 77 to 81 GHz frequency range are the hardware foundation of many of the most safety-critical features in modern Advanced Driver Assistance Systems. These sensors detect the distance, speed, and relative position of surrounding objects — other vehicles, pedestrians, cyclists, and stationary obstacles — with a precision and environmental reliability that camera-based systems alone cannot consistently match.

The specific road safety value of radar in the Indian context lies in its performance in conditions where camera-based systems are most likely to fail. Fog on northern India's highways during winter months, dust on rural roads, heavy monsoon rain, and the darkness of poorly lit rural and peri-urban roads all degrade optical camera performance significantly — yet radar sensors maintain their detection accuracy across all of these conditions. The ability to detect a stationary truck on a foggy highway, a pedestrian emerging from shadow, or a vehicle braking suddenly ahead — before the human driver or a camera-based system can identify the hazard — is precisely the capability that can prevent the accidents that currently claim lives on Indian roads every day.

With the radar licensing exemption now in place, automakers can integrate these sensors across a broader range of vehicle models without the regulatory friction that previously made deployment commercially complex. Features including automatic emergency braking, adaptive cruise control, blind-spot detection, and rear cross-traffic alert — each of which addresses a specific and documented category of accident causation — can now reach Indian roads faster, more affordably, and across more vehicle segments than was previously possible.

V2X Communication — The 5.9 GHz Band Exemption Explained

Vehicles That Talk to Each Other and to the Road Itself

Alongside the radar exemption, the government has granted a separate exemption for Vehicle-to-Everything communication systems operating in the 5.9 GHz band — a regulatory step that opens the door to one of the most transformative road safety technologies currently in global deployment. V2X communication enables vehicles to exchange safety-critical information with other vehicles, with roadside infrastructure such as traffic signals and warning systems, and — in more advanced implementations — with vulnerable road users through smartphone applications.

The road safety scenarios that V2X addresses are those in which the fundamental problem is information — specifically, the absence of timely, accurate information about hazards that are not yet visible to the approaching driver. A vehicle approaching a blind junction does not know whether cross-traffic is running a red light. A driver on a foggy highway does not know whether a vehicle ahead has braked suddenly. A driver about to change lanes does not know whether a vehicle in the adjacent lane is accelerating in the blind spot. V2X communication addresses each of these information gaps by enabling the vehicles and infrastructure involved to share data directly — delivering warnings to drivers before hazards become visible, and before the reaction time window that determines survival has closed.

The 5.9 GHz band exemption aligns India with the frequency allocation used for V2X communication in the US and EU — creating a foundation of spectrum compatibility that enables globally developed V2X hardware to operate in India without modification. Combined with the Ministry of Road Transport and Highways' separate proposal to allocate 30 MHz of spectrum in the 5.875 to 5.905 GHz range specifically for V2V communication, the 5.9 GHz exemption creates a coherent regulatory architecture for connected vehicle deployment in India that is increasingly aligned with international standards.

Aligning India With US and EU Automotive Safety Standards

Global Hardware, Global Safety, Indian Roads

One of the most practically significant consequences of India's radar and V2X frequency exemptions is the alignment they create between India's automotive regulatory environment and the standards followed in the United States and the European Union. This alignment has direct and immediate commercial implications for every automaker operating in the Indian market.

Prior to the exemptions, deploying radar-based ADAS features and V2X communication systems in Indian-market vehicles required either navigating the Indian licensing process for the relevant frequency bands or developing market-specific hardware configurations that avoided the need for licensing — both of which added cost, time, and complexity to the deployment of technologies that were already commercially available in global vehicle platforms. The exemptions eliminate this India-specific regulatory overhead entirely — enabling automakers to use the same globally available hardware in Indian-market vehicles that they use in US and EU variants of the same models.

This hardware standardisation has implications that extend beyond individual vehicle models to the entire automotive supply chain. Component manufacturers, semiconductor suppliers, software developers, and system integrators who develop radar and V2X solutions for the US and EU markets can now address the Indian market with the same products — reducing development costs, accelerating time-to-market, and creating the economies of scale that ultimately enable these safety technologies to reach more affordable vehicle segments where they can have the greatest road safety impact.

Automakers Who Stand to Benefit — From Mercedes to Maruti

Premium Brands and Mass-Market Manufacturers Both Gain

The frequency exemptions create opportunities across the full spectrum of India's automotive market — from the premium international brands that already offer comprehensive ADAS suites globally to the mass-market domestic manufacturers whose high-volume production makes them the most consequential actors for road safety outcomes across the Indian vehicle fleet.

Manufacturers such as Mercedes-Benz and BMW, which already offer advanced safety systems internationally, could introduce the same technologies more easily in India — removing the market-specific regulatory barrier that previously complicated or delayed the Indian deployment of features that their global vehicle platforms already incorporate. For buyers of premium vehicles in India, this means faster access to the full suite of radar-based safety features that Mercedes and BMW offer in their home markets.

The more significant road safety impact, however, is likely to come from domestic manufacturers. Maruti Suzuki, Tata Motors, and Mahindra and Mahindra — whose combined market share covers the vast majority of new vehicle sales in India — may expand the availability of ADAS features across more affordable models as the regulatory and supply chain barriers to radar sensor deployment are reduced. A radar-enabled automatic emergency braking system that reaches a Maruti Alto or a Tata Tiago — vehicles that are purchased in vastly larger numbers than any premium model — has an order-of-magnitude greater impact on India's road safety aggregate than the same feature available only in vehicles costing twenty times as much.

The automotive technology suppliers and chipmakers behind these systems — including global leaders such as Bosch, Continental, and the semiconductor manufacturers whose radar and V2X chips power these systems — also benefit from the expanded Indian market access that the exemptions create, deepening the supply chain ecosystem that will be needed to deliver connected vehicle safety technology at Indian automotive scale.

India's Road Fatality Crisis and the Technology Response

1.77 Lakh Deaths in 2024 — Technology as a Systemic Intervention

India recorded more than 1.77 lakh road fatalities in nearly five lakh accidents in 2024 — making road safety a public health crisis of the first order that demands systemic, scalable interventions alongside the enforcement, awareness, and infrastructure improvements that have been the primary tools of India's road safety governance. Technology — specifically the radar sensing and V2X communication enabled by the new frequency exemptions — represents exactly the kind of systemic, vehicle-level safety layer that can provide a continuous protective function across every journey, regardless of enforcement presence, road conditions, or individual driver behaviour in any given moment.

Experts believe technologies such as radar sensors and V2X communication can help reduce accidents by improving driver awareness and reaction times — addressing the fundamental causation mechanism of the majority of road accidents, which is not malice or recklessness but the human cognitive limits of attention, perception, and reaction speed in complex, fast-moving road environments. A vehicle equipped with radar-based emergency braking that activates in 150 milliseconds when a hazard is detected provides a safety intervention that no human driver — however attentive and experienced — can reliably replicate.

India's radar and V2X frequency exemptions are not, on their own, a solution to the road safety crisis. They are a regulatory enabler — removing a barrier to the deployment of proven safety technology that, combined with India's mandatory ADAS regulations for heavy vehicles, the proposed V2V communication mandate, and the broader framework of enforcement, awareness, and infrastructure investment, contributes to a systemic road safety improvement strategy that is finally beginning to match the scale and urgency of India's road fatality challenge.
