Why Vehicle Safety and Emission Rules Matter in 2026

Delhi’s air quality is regularly ranked among the worst in the world. Mumbai faces severe congestion from poorly maintained vehicles. Every year, thousands of people die in accidents caused by faulty brakes, bald tyres, and overloaded trucks with no working headlights.

These are not just environmental or safety statistics. They are the reason India enacted Chapter VII of the Motor Vehicles Act, 1988 and why the Central Motor Vehicles Rules, 1989 prescribe detailed construction and equipment standards for every vehicle on Indian roads.

If you own a vehicle, drive one, work in the automotive industry, or are preparing for law exams — understanding these rules is not optional. Traffic police now use AI-powered cameras and Vahan database cross-checks to instantly identify vehicles with expired PUC certificates, failed fitness tests, and non-compliant modifications. The penalties are real, and the enforcement is growing sharper every year.

This guide covers everything: Chapter VII of the MV Act, CMVR construction standards, BS6 emission norms, PUC certificate rules, vehicle fitness requirements, the scrappage policy, and the latest 2026 updates — all sourced from official government documents.

What Are Vehicle Safety Rules Under the Motor Vehicles Act, 1988?

Vehicle safety rules in India are set by Chapter VII of the Motor Vehicles Act, 1988 (Sections 106–120) and the Central Motor Vehicles Rules, 1989 (CMVR). These rules prescribe standards for the construction, equipment, and maintenance of all motor vehicles — including brakes, lights, tyres, load limits, seat belts, airbags, mirrors, and exhaust emissions. Any vehicle that does not meet these standards cannot legally be used on Indian roads.

Chapter VII is the safety backbone of the entire Motor Vehicles Act. While earlier chapters deal with who can drive and which vehicles are allowed — Chapter VII deals with what those vehicles must be made of and how they must be maintained. It gives MoRTH the authority to prescribe technical standards and empowers the Central Government to issue rules through the CMVR.

Section	Subject	What It Controls
Sec 106	Standards for construction and maintenance	Central Govt may prescribe standards for construction, equipment, and maintenance of all motor vehicles
Sec 107	Power to restrict use of vehicles	State Govt may prohibit use of vehicles that do not comply with prescribed standards
Sec 108	Duty to maintain vehicles in safe condition	Every owner must maintain vehicle in roadworthy condition at all times
Sec 109	Safety equipment	Helmets, seat belts, child restraints — mandatory safety equipment specifications
Sec 110	Alteration of vehicles	No structural alteration without prior approval — prevents dangerous modifications
Sec 110A	Recall of vehicles (2019 Addition)	Central Govt may order recall of defective vehicles; manufacturer must refund or replace
Sec 111	Maintenance of speed governors	Specified vehicles must maintain functioning speed governors
Sec 112	Speed limits	Maximum speed limits for different vehicle classes — enforceable under Chapter XIII
Sec 119	Precautions against fire	Vehicles carrying inflammable or hazardous goods must have fire safety equipment
Sec 120	Maintenance of standards	Vehicles must be maintained to the standard at which they were registered

Vehicle Construction and Equipment Standards Under CMVR 1989

The Central Motor Vehicles Rules, 1989 (CMVR) is the subordinate legislation made under Section 106 of the Motor Vehicles Act. It translates the Act’s broad mandate into specific, measurable technical standards. The CMVR is regularly updated by MoRTH — with the 21st Amendment (Nov 2022), 22nd Amendment (Dec 2022), and subsequent updates adding new standards for armoured vehicles, hydrogen fuel cell vehicles, and EV safety.

Mandatory Safety Equipment Under CMVR

Brakes: Every vehicle must have at least two separate braking systems. Heavy vehicles must have additional parking brakes and, for new models, ABS (Anti-lock Braking System) is mandated by AIS standards.
Lights and signals: Headlights, tail lights, brake lights, turn indicators, hazard lights, and reverse lights are all mandatory under CMVR Rule 99–107. Daytime Running Lights (DRL) are mandatory for new vehicles from 2021.
Tyres: Minimum tread depth standards are prescribed. Bald or worn tyres are a violation under Section 190 and CMVR Rule 104.
Seat belts: Mandatory for all front seat occupants in cars under Section 194B. CMVR standards prescribe the technical specifications for seat belts in new vehicles.
Rear-view mirrors: Mandatory on both driver’s and passenger’s side for cars; on the right side for two-wheelers.
Airbags: Mandatory for front seats in new passenger vehicles from 1 April 2021 (minimum 2 airbags per vehicle — driver and front passenger). Six airbags mandatory for new M1 category vehicles (passenger cars) from 1 October 2023.
Speed governor: Mandatory for all new commercial vehicles (buses, trucks) — must be set to the prescribed maximum speed and cannot be tampered with (Section 111).
High Security Registration Plates (HSRP): Mandatory for all new vehicles sold in India from 2005 onwards. Tamper-proof, IND-embossed chromium hologram plates as per CMVR specifications.

Prohibition on Structural Modifications (Section 110)

Section 110 of the Motor Vehicles Act prohibits any alteration to the structure, dimensions, or engine of a registered vehicle without prior approval from the registering authority. Common illegal modifications include: increasing engine capacity, altering the body to increase seating beyond the registered capacity, changing the fuel type without CMVR approval, and modifying the exhaust system to increase noise or emissions. Illegal modifications make a vehicle non-compliant with its registration certificate — and can void the vehicle’s insurance.

2019 Addition — Vehicle Recall (Section 110A): If a defect in any vehicle model poses a danger to the environment, the driver, or other road users, the Central Government can order a mandatory recall of all affected vehicles. The manufacturer must either reimburse the full purchase price or replace the vehicle with one of equivalent or better specification. This provision — inserted by the 2019 Amendment — is modelled on global automotive recall frameworks. Source: Section 110A, MV(Amendment) Act 2019.

What is BS6 emission norm in India and when did it come into effect?

BS6 (Bharat Stage VI) is India’s most stringent vehicle exhaust emission standard, equivalent to Euro 6 norms. It was introduced by MoRTH and became mandatory for all new petrol, diesel, and CNG vehicles sold in India from 1 April 2020 — two years ahead of the original 2022 schedule. BS6 norms prescribe maximum permissible levels of particulate matter (PM), nitrogen oxides (NOx), carbon monoxide (CO), and hydrocarbons (HC) in vehicle exhaust. All new vehicles must comply before they can be registered. Source: MoRTH; CMVR Schedule VI.

Bharat Stage Emission Standards — Evolution

Standard	Equivalent (Euro)	Introduced	Key Pollutant Reductions
BS1 (Bharat Stage I)	Euro 1	2000	Basic carbon monoxide and hydrocarbon limits
BS2 (Bharat Stage II)	Euro 2	2001 (metro)	Tighter HC and CO; stricter particulate matter
BS3 (Bharat Stage III)	Euro 3	2005 (metro)	NOx limits introduced; catalytic converter needed
BS4 (Bharat Stage IV)	Euro 4	2010 (metro); 2017 (nationwide)	Significant PM reduction; diesel particle filters
BS6 (Bharat Stage VI)	Euro 6	1 April 2020 (nationwide)	NOx cut by 68% (diesel); PM cut by 82%; Real Driving Emissions (RDE) testing added

Why India Skipped BS5?

India leapfrogged directly from BS4 to BS6 — skipping BS5 entirely. This was a deliberate policy decision announced in 2016 by MoRTH, driven by severe air quality concerns in Indian cities and supported by Supreme Court directions on vehicular pollution. The two-year early implementation (2020 instead of 2022) was also a direct response to Delhi’s pollution crisis. Source: MoRTH official notification; PIB.

BS6 Phase 2 (OBD-II) — Effective 2023

BS6 Phase 2, which requires On-Board Diagnostics (OBD-II) systems in all new vehicles, became mandatory from 1 April 2023. OBD-II monitors a vehicle’s emission control systems in real time and alerts the driver (via a dashboard warning light) if any emission-related component is malfunctioning. This means emission failures can now be detected without a roadside test — and a vehicle with a malfunctioning emission system is technically non-compliant with BS6 standards even if it passes a roadside PUC test.

What Is a PUC Certificate and Why Is It Mandatory?

What is a PUC certificate and how long is it valid in India?

A Pollution Under Control (PUC) certificate is a mandatory document that verifies a vehicle’s exhaust emissions are within the limits prescribed under the Central Motor Vehicles Rules, 1989. All motor vehicles on Indian roads — including two-wheelers, cars, and commercial vehicles — must carry a valid PUC certificate at all times. For BS6 vehicles: PUC is valid for 1 year from the first test (within 3 months of purchase) and every year thereafter. For BS4 and older vehicles: valid for 6 months. Issued by authorised PUC testing centres. Source: CMVR Rule 115; Section 190, MV Act.

PUC Certificate — Key Rules at a Glance

Rule	Details	Authority
Who needs it	Every motor vehicle on any public road in India — no exceptions	CMVR Rule 115
When to get first PUC	Within 1 year for new BS6 vehicles; within 3 months for older vehicles	CMVR Rule 115
Validity — BS6 vehicles	1 year (annually renewable)	CMVR (post-2020)
Validity — BS4 and older	6 months	CMVR Rule 115
Where to get it	Any MoRTH-authorised PUC testing centre; linked to Vahan database	CMVR; Vahan portal
Cost	Approx. Rs. 60–100 per test (varies by state)	State transport dept.
Digital PUC	PUC details updated on Vahan database in real time after each test	Vahan portal
Penalty for expired PUC	Rs. 1,000 fine + up to 3 months imprisonment under Section 190(2)	Sec 190(2), MVA 1988

Example: Sameer drives his 5-year-old petrol car. His PUC expired 2 months ago. At a toll booth, an ANPR camera cross-references his number plate with the Vahan database and detects no valid PUC on record. An e-Challan of Rs. 1,000 is automatically generated and sent to his registered mobile number. He must pay at echallan.parivahan.gov.in within 60 days. He also cannot renew his vehicle’s insurance or fitness certificate without a valid PUC. The lesson: set a reminder 2 weeks before your PUC expiry.

Vehicle Fitness Certificate Rules — Section 56 and CMVR

A Certificate of Fitness (CF) is the official document certifying that a transport vehicle meets the construction, equipment, and safety standards prescribed under the Motor Vehicles Act and CMVR. Section 56 makes it mandatory for every transport vehicle. Private vehicles do not require a CF — but they must still comply with the construction standards and valid PUC.

Vehicle Category	Initial CF Validity	Renewal Frequency	Who Issues
New transport vehicle (goods/passenger)	2 years from registration	Annual thereafter	Motor Vehicle Inspector / authorised ATS
Old transport vehicle (after 2 years)	1 year per renewal	Annual	Motor Vehicle Inspector / authorised ATS
Three-wheelers (commercial)	1 year from registration	Annual	Motor Vehicle Inspector
Private vehicle (car, two-wheeler)	Not required	Not required	N/A — but PUC mandatory
Vehicle over 15 years (private)	Fitness test mandatory	Every 5 years (post RC renewal)	Authorised Testing Station (ATS)

Since 2021–22, automated testing stations (ATS) have been introduced across India, providing computerised, corruption-resistant fitness testing. The RVSF (Registered Vehicle Scrapping Facility) framework feeds into this — vehicles that repeatedly fail fitness tests are redirected to the scrappage process.

Vehicle Scrappage Policy India 2021–2026 — Complete Rules

What is the vehicle scrappage policy in India and what are the age limits?

India’s Vehicle Scrappage Policy, notified by MoRTH in 2021, mandates that private vehicles older than 20 years and commercial vehicles older than 15 years must undergo a mandatory automated fitness test at an Authorised Testing Station (ATS). Vehicles that fail the test are declared End of Life Vehicles (ELVs) and must be scrapped at a Registered Vehicle Scrapping Facility (RVSF). The policy is tracked digitally through the Vahan portal. Source: MoRTH; CMVR Amendment 2022; Vehicle Scrappage Policy Notification 2021.

Scrappage Policy — Key Rules at a Glance

Rule	Private Vehicle	Commercial Vehicle	Government Vehicle
Age trigger	20 years	15 years	15 years
Action required	Mandatory automated fitness test at ATS	Mandatory fitness test at ATS	Mandatory scrappage — no renewal allowed
If test passed	RC renewed for 5 years	CF renewed for 1 year	N/A — must scrap
If test failed	Declared ELV — must scrap at RVSF	Declared ELV — must scrap	Must scrap
Incentive for scrapping	Up to 5–8% discount on new vehicle + road tax waiver in some states	Proportional incentive	N/A
Digital tracking	Vahan database tracks fitness history	Vahan database	Vahan database

EPR Mandates — FY 2026-27

Under Extended Producer Responsibility (EPR) rules notified by the Ministry of Environment, Forest and Climate Change (MoEFCC), automobile manufacturers and importers are required to take back End of Life Vehicles from FY 2026–27. Producers must register on the digital EPR portal, report annual ELV collection targets, and ensure all scrapping is done at AIS-129 certified RVSFs. Non-compliance attracts penalties under the Environment Protection Act, 1986 read with the Motor Vehicles Act scrappage framework. Source: MoEFCC notification; psrcompliance.com.

5 Common Mistakes Vehicle Owners Make About Safety and Emission Rules

Mistake 1 — ‘My new BS6 car does not need a PUC for the first year.’ Wrong. New BS6 vehicles must get their first PUC test within 1 year of purchase — many owners miss this deadline and unknowingly drive with an expired PUC. Set a reminder at 11 months from purchase date.
Mistake 2 — ‘Tinted film on windows is just a style choice — it is not illegal.’ Under CMVR standards, windshield and front side window glass must allow at least 70% visible light transmission (VLT). Excessive tinting (darker than 70% VLT) violates CMVR Rule 100 and is a Section 190 offence. Police can order removal on the spot.
Mistake 3 — ‘My car is more than 15 years old but I got the RC renewed — so I am fine.’ An old private vehicle’s RC renewal (after 15 years) does not automatically clear it of fitness requirements. The vehicle must pass a fitness test at an ATS. Simply renewing the RC without a fitness test is incomplete and does not legalise an unsafe vehicle.
Mistake 4 — ‘Modifying my motorcycle exhaust for a sportier sound is just cosmetic.’ Replacing the original exhaust with a louder aftermarket system is a structural modification under Section 110. It also likely results in the vehicle exceeding the CMVR noise limits and the BS6 emission standards. This is an illegal modification that can result in RC cancellation and insurance voiding.
Mistake 5 — ‘If I scrap my old car, I lose money.’ Under the Vehicle Scrappage Policy 2021, scrapping your old vehicle at a RVSF provides a Scrappage Certificate that entitles you to road tax concessions (up to 25% for private cars) and incentive discounts from manufacturers on new vehicle purchases. Check the MoRTH-notified RVSF near you through the Vahan portal.

FAQ — Vehicle Safety and Emission Rules India

Q1. What is BS6 emission norm in India?

BS6 (Bharat Stage VI) is India’s current emission standard, similar to Euro 6. It became mandatory from 1 April 2020 for all new petrol, diesel, and CNG vehicles under CMVR, 1989. BS6 reduced pollution significantly (PM by 82% and NOx by 68%). India skipped BS5. BS6 Phase 2 with OBD-II started from 1 April 2023.

Q2. How long is a PUC certificate valid in India?

For BS6 vehicles, the PUC certificate is valid for 1 year (first test within 1 year of purchase, then yearly renewal). For BS4 and older vehicles, it is valid for 6 months and must be renewed twice a year. PUC is issued by authorised centres and updated on the Vahan database.

Q3. What is the vehicle scrappage policy in India 2026?

India’s Vehicle Scrappage Policy (2021) says private vehicles over 20 years and commercial vehicles over 15 years must pass fitness tests. Government vehicles are scrapped after 15 years. Failed vehicles are declared ELVs and scrapped at authorised centres. Owners get benefits like tax discounts. From 2026–27, manufacturers must recycle old vehicles under EPR rules.

Q4. What happens if a PUC certificate expires in India?

If your PUC expires, it is illegal under the Motor Vehicles Act. You may face a ₹1,000 fine and up to 3 months in jail. AI e-challan cameras can detect and fine you automatically. An expired PUC can also block insurance, RC renewal, and fitness renewal. So, renew your PUC quickly at an authorised centre.

Q5. Is window tinting legal in India under CMVR?

Window tinting is allowed only within limits under CMVR Rule 100. The front windshield and front side windows must allow at least 70% light, while rear windows can have up to 50% tint. Darker tint is illegal and can lead to fines. Police can remove it on the spot. Supreme Court also gave guidelines in 2012.

Q6. What is Section 110A of the Motor Vehicles Act?

Section 110A (added in 2019) allows the government to recall vehicles if they have defects that can harm people or the environment. The manufacturer must either refund the full price or replace the vehicle. This rule makes India’s vehicle recall system similar to global standards like the USA and EU.

Q7. Are six airbags mandatory in Indian cars?

From 1 October 2023, all new passenger cars in India must have 6 airbags (driver, passenger, side, and curtain) as per CMVR rules. Earlier, only 2 airbags were required from April 2021. Older vehicles don’t need upgrades, but all new models must follow this rule.
