10 Modifications you can get Challan for


Changing Structure of the vehicle

Since modifying the vehicle’s structure can make it weaker, you are not allowed to change the structure of your car.

Aftermarket Exhaust

Aftermarket exhausts that are louder than what is considered legal can be a cop-magnet. If your aftermarket exhaust doesn’t come with the seal of approval of the RTO, for all means and purposes you are breaking the law.


If you are fitting new tyres, you should make sure that the tyres are not sticking out from the car body. You cannot fit very big tyres on your vehicles either. You can, but it won’t be legal.

Aftermarket Accessories

You should not install steering spinners, IRVM screens or Bull Bars aftermarket, you cannot make variations like changing the number of seats your car has.

Aftermarket Alloy Wheels

This is one of the customizations that a lot of motorists go for. However, oversized alloy wheels are banned and you will have to face the repercussions if caught.

Engine Modifications

The car engine can be modified. But you need to get a permit from the Road Transport Office (RTO) first. Some changes to the engine are legal while others are not. 

 Pressure Horns

The horns you install in your vehicle cannot be louder than 80 decibels. If you are getting them aftermarket, make sure to comply with these norms.

The car roof stays

You cannot turn your car into a monster truck, limo or convertible. But if you are still desperate to have a wind-in-the-hair experience while driving, you can invest in a Mahindra Thar.


If you feel like improving your car’s ride quality you can go for a custom suspension. Getting a new upgraded suspension is okay. But this should not mess with the ground clearance of the vehicle.

Colour Change

It is legal to get your car painted in a completely different colour. But you will need to get the new colour approved by the RTO.
