Speed Limiter Laws in India: AIS-018 Requirements

India has the world’s second-largest commercial vehicle fleet and one of the world’s highest road fatality burdens. The country recorded over 150,000 road deaths in 2022 alone — a figure that places India’s road safety challenge in stark terms. Commercial vehicle speeding has been consistently identified as a major contributing factor, and India’s mandatory speed limiter regime has been in place since 2015 with ongoing refinement.

For vehicle manufacturers exporting to India, Indian fleet operators, and international organisations working in the Indian market, understanding the AIS-018 standard and CMVR framework is essential.

The Regulatory Framework: CMVR and AIS-018

India’s speed limiter requirement for commercial vehicles sits within the Central Motor Vehicle Rules (CMVR), the national regulatory framework governing vehicle standards and safety. The technical standard that speed limiting devices must meet is AIS-018 — the Automotive Industry Standard 018 published by the Automotive Research Association of India (ARAI).

AIS-018 defines the performance requirements for speed governing devices fitted to motor vehicles in India. The standard was developed with reference to international standards including ECE R89, though there are significant differences in specific requirements and the certification process.

The Role of ARAI

The Automotive Research Association of India (ARAI), based in Pune, is India’s primary vehicle type-testing agency. ARAI conducts AIS-018 testing for speed governing devices and issues type-approval for products that meet the standard. Manufacturers seeking to sell speed limiting devices in India must obtain ARAI type-approval.

The International Centre for Automotive Technology (ICAT), based in Manesar, Haryana, also has accreditation for vehicle component testing and can conduct AIS-018 testing. Some manufacturers choose ICAT as their testing body rather than ARAI, particularly for products intended for the north Indian market.

Mandatory Speed Limiter Requirements by Vehicle Type

India’s CMVR mandates speed limiters across a range of commercial vehicle categories, with specific set speed requirements:

Vehicle Category	Application	Speed Limiter Setting
Buses (M2/M3)	Public service vehicles, school buses	80 km/h
Trucks N2/N3	Goods vehicles over 7.5t GVM	80 km/h
Maxi cabs / Taxis	Multi-passenger taxis	80 km/h
Goods vehicles (general)	Over 3.5t GVM	80 km/h
Hazardous goods tankers	ADR-equivalent loads	60 km/h

The 80 km/h maximum setting for most commercial vehicle categories reflects India’s road conditions — a mix of national highways where speeds are potentially higher and state and district roads where conditions are more varied and dangerous. The lower setting for hazardous goods vehicles recognises the additional risk profile of those operations.

School Bus Requirements

School buses are a particular enforcement priority in India following several high-profile accidents. CMVR requires not only speed limiters set to 80 km/h on school buses, but additional safety equipment and driver controls. Speed limiter compliance in this category is closely monitored by state transport authorities.

The Certification Process: From ARAI Testing to Vehicle Fitting

The process for bringing an AIS-018-compliant speed limiter to the Indian market involves several stages:

Stage 1: Technical Documentation Submission

The manufacturer submits technical documentation to ARAI or ICAT, including device specifications, circuit diagrams, and a description of the operating principle. For a drive-by-wire device such as AutoKontrol’s System 80, the electronic architecture and signal processing methodology must be documented in detail.

Stage 2: Laboratory Testing

ARAI/ICAT laboratory testing covers:

• Speed accuracy: The device must not allow the vehicle to exceed the set speed by more than a defined tolerance (similar to ECE R89 requirements)
• Tamper resistance: Tests assess the device’s resistance to bypass or defeat
• Environmental testing: Temperature, vibration, and humidity testing to verify performance across Indian operating conditions
• Electromagnetic compatibility (EMC): Testing to ensure the device does not cause or suffer from electromagnetic interference

Stage 3: Vehicle-Level Testing

Following component-level approval, vehicle-level testing verifies that the installed device performs correctly in a complete vehicle. This typically involves dynamic testing on a test track.

Stage 4: Type-Approval Certificate

On successful completion of testing, ARAI or ICAT issues a type-approval certificate. This certificate is the basis for the device being installed on vehicles and presented at inspection.

State-Level Fitment Verification

Once a device has type-approval, fitting to vehicles is typically verified by Regional Transport Offices (RTOs). Each state manages its own RTO network, and state-level enforcement practices can vary. In some states, speed limiter inspection is closely integrated with the annual fitness certificate (FC) process for commercial vehicles.

Enforcement Challenges in India

India’s speed limiter enforcement landscape is complex:

RTO Variation

The 28 states and 8 union territories each have their own RTO networks with varying levels of enforcement resource and consistency. A device accepted by one RTO may face different scrutiny in another state. Operators running inter-state routes — common in India’s large domestic freight market — can face inconsistent enforcement experiences.

Informal Bypass Market

India has a well-documented problem with informal speed limiter bypass. Devices that appear compliant at inspection but can be easily disabled are available in some markets. This undermines the road safety intent of the regulation and creates a compliance risk for operators who fit non-certified or easily bypassed devices — particularly when incidents occur and insurance or liability questions arise.

Improving Enforcement Through Technology

The Indian government has been investing in technology-based enforcement approaches, including integration of speed limiter data with vehicle tracking systems under the Vehicle Location Tracking (VLT) mandate. Commercial vehicles above 7.5t GVM and public service vehicles are now required to carry GPS-based vehicle location tracking devices, and there is policy interest in integrating speed limiter monitoring with VLT data.

India’s Commercial Vehicle Market: Scale and Opportunity

India’s commercial vehicle fleet is enormous:

• Over 4 million registered commercial vehicles in the heavy and medium categories
• One of the world’s fastest-growing truck and bus markets, with domestic manufacturers including Tata Motors, Ashok Leyland, Mahindra, and Eicher dominating the market
• A significant and growing market for imported specialist vehicles in categories such as construction, mining, and oil and gas

The scale of the Indian commercial vehicle market creates substantial demand for compliant speed limiting devices — and, as enforcement improves, demand for quality over minimum cost. International manufacturers with proven ECE R89 type-approval credentials and robust device performance have a significant advantage in demonstrating quality to Indian buyers and approval authorities.

AutoKontrol’s experience with ECE R89 type-approval processes in Europe provides a strong foundation for engaging with ARAI’s AIS-018 requirements. The technical similarity between the two standards — and ARAI’s awareness of ECE R89 as an international benchmark — means that manufacturers with European type-approval can present credible technical documentation packages to support Indian certification.
