Share
📈 Why You Must Know the Rules Before Modifying Your Car
Car modification is a huge trend in India – from alloy wheels to LED lights and performance upgrades. But in 2025, the laws around car customizations have gotten stricter, with fines up to ₹2,000 or RC cancellation if you're not compliant.
Understanding what’s allowed and what’s banned can save you a lot of hassle.
✅ Legal Car Modifications in India (2025)
These are safe and permissible mods under Indian Motor Vehicle Act (MVA):
1. Alloy Wheels – Permitted as long as the size stays within the manufacturer’s limits.
2. Tyre Upgrades – Slight upgrades (1-2 inches) are fine. Avoid oversized tyres.
3. Aftermarket Seat Covers – Leather, fabric, bucket-style covers are fully legal.
4. Roof Wraps & Paint Protection Films (PPF) – Allowed; doesn’t alter chassis.
5. Parking Sensors / Reverse Camera – Legal and encouraged for safety.
6. Steering Wheel Covers & Interior Trim Mods – Fully legal.
7. Infotainment Upgrades – As long as screens don’t distract while driving.
8. TPMS / Dash Cams / GPS Trackers – Legal; recommended for safety.
⛔ Illegal Car Modifications in India (2025)
These could lead to penalties, RC issues, or insurance rejection:
1. Structural Alteration – Cutting/chopping roof (convertibles), or body shape changes.
2. Bull Bars / Crash Guards – Banned by MoRTH due to pedestrian safety.
3. Aftermarket Exhausts – Loud or performance exhausts (above 82 dB) are illegal.
4. Illegal LED Bars / Roof Lights – External high-intensity lights = banned.
5. Horn Replacement – Air horns / pressure horns = illegal.
6. Chassis Number Tampering – Strictly prohibited and a criminal offense.
7. Engine Swap / Turbo Mods – Unless approved by RTO (very rare).
8. Tinted Windows (Beyond Limit) – Front and rear must allow 70% visibility; sides 50%.
🚫 Even cosmetic changes that alter the 'original specifications' in RC can void your insurance.
🎓 What the Supreme Court & MoRTH Say
Supreme Court in 2019 ruled that "No vehicle shall be modified in a manner that alters its original specifications".
Only RTO-approved design changes by certified workshops are allowed.
MoRTH FAQs clearly list body kits, spoilers, and loud exhausts as punishable modifications.

Inform insurance if you make any changes that affect performance or looks.
💡 Conclusion: Modify Smart, Stay Legal
Personalizing your car is fun – but don’t get caught in a legal trap.
When in doubt, stick to cosmetic, non-structural, and MoRTH-compliant modifications. Use certified installers and avoid noisy or flashy setups that grab the wrong kind of attention.
