🚦 New Rules for Radar Speed Measurement Equipment

[YAGAY andSUN]

🚦 New Rules for Radar Speed Measurement Equipment

• Centre notifies rules for ‘Radar equipment for the measurement of the speed of vehicles’ under the Legal Metrology (General) Rules, 2011

Here’s a comprehensive but easy-to-digest summary of the new rules for radar speed measurement devices, notified by the Department of Consumer Affairs:

📅 Effective From: 1st July 2025
📢 Announced by PIB Delhi on 18 April 2025

🎯 Purpose

To:

• Strengthen road safety
• Ensure fair and scientific traffic enforcement
• Build trust in speed monitoring systems

📌 Key Provisions

1. 🔍 Mandatory Verification & Stamping
   • All radar-based speed measuring devices must be verified and stamped by Legal Metrology authorities.
   • Ensures devices are accurate, calibrated, and tamper-proof.
2. 📏 Based on International Standard
   • Rules follow OIML R 91, a global standard for radar speed measurement devices.
   • Ensures consistency with global best practices.
3. 📋 Extensive Consultation
   • Drafted with inputs from:
     • State Legal Metrology Departments
     • Regional Reference Standard Labs (RRSLs)
     • Manufacturers
     • Consumer groups
4. ⚙️ Technical Specifications
   • Devices must function reliably under varying weather and environmental conditions
   • Must include tamper-resistance and proper calibration protocols
   • Uses Doppler radar and other technologies for high-precision speed tracking

👥 How It Benefits Stakeholders

🧍‍♂️ For Citizens:

• No more false penalties due to faulty radar guns
• Greater confidence in enforcement fairness
• Improved road safety through reliable speed control

🏭 For Industry (Manufacturers):

• Clear technical and compliance framework
• Aligned with international norms
• Boosts export potential of Indian-made radar devices

👮‍♂️ For Law Enforcement:

• Use of certified devices boosts credibility and effectiveness
• Enables evidence-based enforcement
• Reduces disputes and public distrust

🏛️ National Impact:

• Supports data-driven governance
• Reduces road fatalities and traffic incidents
• Protects infrastructure from damage due to over speeding

Here's a quick explainer on OIML R 91 and a look at how the new rules could impact specific industries and regions in India:

📘 Quick Explainer: OIML R 91

What is OIML?
The International Organization of Legal Metrology (OIML) sets global standards for measuring instruments used in trade, health, safety, and law enforcement.

OIML R 91 is the specific international recommendation for:

Radar Equipment Used to Measure the Speed of Vehicles

🛠️ Key Features of OIML R 91:

• ✅ Accuracy classification for speed measurements
• 📏 Clear calibration and testing protocols
• 🌧️ Must perform reliably in all-weather/environmental conditions
• 🔒 Protection against tampering or manipulation
• ⚡ Instantaneous and average speed measurement capabilities
• 🎯 Targets vehicles in free-flowing or dense traffic

Using OIML R 91 ensures that speed detection is scientific, standardized, and internationally acceptable, which matters in law enforcement and trade disputes.

📊 Impact of New Radar Rules (Based on OIML R 91)

🏭 Industries Affected:

1. Radar Equipment Manufacturers:
   • Must align with strict technical and legal standards
   • Need certification from Legal Metrology departments
   • Opportunity to export to other OIML-compliant markets
2. Calibration Labs & Testing Facilities:
   • Rise in demand for device verification, testing, and maintenance
   • Boost for Regional Reference Standard Laboratories (RRSLs)
3. Automotive & Transport Tech Firms:
   • Integration of compliant radar modules into smart city traffic systems
   • New business models for data-based traffic enforcement tools

📍 Regional Impacts:

1. Metro Cities (Delhi, Mumbai, Bengaluru, etc.):
   • Higher volume of radar installations → Stricter compliance needed
   • Supports smart traffic enforcement and automated challan systems
2. Tourism & Highway Corridors (e.g. Rajasthan, Goa, NH44):
   • Radar systems will help curb overspeeding by out-of-state drivers
   • Safer roads → boost to tourism and logistics
3. Industrial Zones (e.g. Gujarat, Tamil Nadu, Maharashtra):
   • Local manufacturers get a competitive edge with OIML-compliant products
   • Can enter European, African, and ASEAN radar markets

🌐 Summary: Why It Matters

• Citizens get fairer enforcement.
• Manufacturers get global competitiveness.
• Law enforcement gets trusted tools.
• The country gets a modern, standards-based traffic system.
