The Centre on Friday notified new rules for radar equipment for measuring the speed of vehicles in order to strengthen road safety and ensure fairness in traffic enforcement.&nbsp;
The rules, notified by the Department of Consumer Affairs, make it mandatory for all radar-based speed measurement equipment to be verified and stamped by Legal Metrology authorities., according to an official statement.
These rules will come into force from July 1, 2025, providing sufficient time for industries and enforcement agencies to comply with the provisions, the statement said.&nbsp;
This will ensure that such devices are accurate, calibrated and legally compliant, thereby enhancing transparency, public trust and enforcement integrity. Verified radar systems are vital for applications such as traffic speed monitoring, accident prevention, and minimising wear and tear on road infrastructure, the statement explained.
Radar devices operate using technologies like Doppler radar, measuring vehicle speed with high precision. These rules specify detailed technical and safety requirements, ensuring proper calibration, stable operation under various environmental conditions and protection against tampering. Such measures will foster a culture of technological reliability and legal accountability, the statement said.
The drafting of these rules was undertaken by a committee with technical inputs based on the international standard OIML R 91. Stakeholders, including state Legal Metrology Departments, Regional Reference Standard Laboratories (RRSLs), manufacturers and consumer organisations, were consulted through presentations and public feedback before finalising the rules.
The implementation of these rules provides significant benefits to all stakeholders across the board. For the common citizen, the mandatory verification and stamping of radar-based speed measurement equipment will ensure the accurate enforcement of speed limits, thereby preventing unfair penalties and significantly enhancing road safety. Citizens can drive with greater confidence knowing that enforcement is based on scientifically validated and legally certified instruments, the statement said.
For law enforcement agencies, the introduction of verified and stamped devices ensures a higher degree of operational effectiveness and credibility. These devices allow for reliable, evidence-based enforcement, which is critical for maintaining public trust and improving compliance with speed regulations. The availability of certified and calibrated instruments enables officers to act with confidence and precision, the statement said.&nbsp;
For industries, particularly those involved in manufacturing radar-based speed measuring devices, the new rules establish a clear technical and regulatory framework aligned with international standards such as OIML R 91. This not only encourages domestic innovation and compliance but also enhances the export competitiveness of Indian manufacturers in global markets by ensuring consistency in quality and performance, according to the statement .
At the national level, this initiative is a key step towards data-driven governance in traffic management. It helps reduce road fatalities, enhances discipline on highways and supports sustainable economic development by minimising the social and economic costs associated with road accidents, vehicle wear and tear, and damage to infrastructure. Overall, the rules contribute to building a safer and more technologically advanced transport ecosystem in the country.
This move marks a significant step forward in India's ongoing reforms to modernise legal metrology infrastructure, ensuring that measuring instruments in public enforcement are scientifically robust and legally verifiable, the statement added.
