PM Modi to Launch Vizhinjam International Seaport on May 2

To strengthen road safety and ensure fairness in traffic enforcement, the Department of Consumer Affairs has notified rules for ‘Radar equipment for the measurement of the speed of vehicles’ under the Legal Metrology (General) Rules, 2011.

- 

These rules will come into force from July 1, 2025, providing sufficient time for industries and enforcement agencies to comply with the provisions, as per a statement from Ministry of Consumer Affairs.

These rules make it mandatory for all radar-based speed measurement equipment to be verified and stamped by Legal Metrology authorities. 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 minimizing wear and tear on road infrastructure.

The drafting of these rules was undertaken by a committee with technical inputs based on international standard OIML R 91. Stakeholders, including State Legal Metrology Departments, Regional Reference Standard Laboratories (RRSLs), manufacturers and consumer organizations were consulted through presentations and public feedback before finalizing 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.

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.
