Under the new provisions, it will be mandatory for all radar-based speed measuring devices to be verified and stamped by Legal Metrology authorities.
The mandatory verification will help ensure that speed enforcement is based on scientifically accurate and legally certified instruments, reducing the risk of unfair penalties and promoting road safety.“>
In a move aimed at strengthening road safety and ensuring fairness in traffic enforcement, the Department of Consumer Affairs has notified new rules for ‘Radar equipment for the measurement of the speed of vehicles’ under the Legal Metrology (General) Rules, 2011. The rules will come into effect from July 1, 2025, giving sufficient lead time for industries and enforcement agencies to comply with the regulatory framework.Under the new provisions, it will be mandatory for all radar-based speed measuring devices to be verified and stamped by Legal Metrology authorities. This verification process will ensure that all such equipment is accurate, calibrated, and legally compliant, thereby enhancing transparency, enforcement integrity, and public confidence in the use of speed detection systems.The rules are based on the international standard OIML R 91 and were finalized after extensive stakeholder consultations, including inputs from State Legal Metrology Departments, Regional Reference Standard Laboratories (RRSLs), manufacturers, and consumer organizations.Key Benefits for Stakeholders
For Citizens: The mandatory verification will help ensure that speed enforcement is based on scientifically accurate and legally certified instruments, reducing the risk of unfair penalties and promoting road safety.For Industry: Manufacturers of radar-based speed measurement equipment will benefit from a clear, internationally aligned technical framework, boosting domestic innovation and global export competitiveness.
For Law Enforcement: The adoption of verified devices will significantly enhance operational credibility and ensure reliable, evidence-based enforcement, essential for maintaining public trust in road traffic regulations.
Enhancing Data-Driven Governance
The introduction of standardized radar systems is expected to contribute to a data-driven approach to traffic management, reducing road accidents, minimizing vehicle wear and tear, and cutting down on infrastructure damage. It also supports the government’s broader push for technological modernization in legal metrology, bringing enforcement practices in line with global best practices.Radar-based speed measurement devices typically function using Doppler radar technology, offering high-precision speed tracking even in varied environmental conditions. The new rules mandate tamper-proof mechanisms, proper calibration, and stability in operations—fostering a regulatory ecosystem grounded in technological reliability and legal accountability.This initiative represents a significant step forward in India’s metrology reforms, ensuring that speed measurement in public enforcement is not just technologically advanced but also scientifically validated and legally verifiable.
