[2022 Updated] 10 legal Car Modifications Rules in India

Car modification rules are so easy to understand. It can save lots of money and time.

In our country, many people love to modify their cars and they do modifications.

Car modification fun is spoiled when traffic police cut ‘challan’ for illegal car modifications. I have faced the same problems many times then I studied and telling you about the 10 Car modification rules which are fully legal .

10 legal Rules of Car Modification in India

If  Car Modification details are matched with RC then you don’t have to think about any thing.

Let us take a example: Suppose you have a car and runs on a petrol. You think that petrol is too costly and planned to place a CNG kit in your car, So that it can run Eco Friendly and pocket friendly.

If you see your RC, It is clearly mentioned that you have a petrol variant car. If you put CNG then the details will mismatch.

Now you can say this car modification is not legal until you change it into RC.

car modification car color

1.Colour

As I have discussed If your car details are matching with RC  then it is legal.

If you want to change color of your car ,yes you can change it by taking the permission from RTO.

But Now in modern era there are lots of alternative rather than paint a Car. You can use vinyl wraps. Car sticker also can be used and they are absolutely legal.

Benefit of vinyl wraps is that you can remove easily if you don’t like it. The average life of the vinyl is 2-2.5 years. Partially wraps can also be done with different patterns & textures.

legal modification for tyres

2.Tyres

If you are planning to replace your car tires, you should check the size of the tires that it is not coming out from the car body. You can not fit larger tires in your vehicle because of two reasons. First, the larger will affect the vehicle’s performance, and Second, and most importantly, it will not legal.

Do you really want larger tires? You can do one thing: if you have a lower variant of the car. You can use bigger tires from the upper variant. It will be legal and it will not affect the performance of the vehicle.

If we talk about the width of the Maruti Suzuki breeza tires for the base model it is 205 mm, and for the upper model, it is 215 mm. Doing these types of Car modifications will not create any issue.

Car modification rules for accessories

3.After Market Accessories

You should not install child lock, power window, IRVM screens from the aftermarket. Let me tell you about one incident, One of my uncles bought a car with two front power windows inbuild in it. After a month he thought he should add two more power windows for a backside. He went and made a fitment of two more power windows from the aftermarket for the rear seats. Car window was working perfectly. He and his family enjoying this new fitment. 

One day he decided to go to the picnic with his wife. In the mid of the route, they met an accident. The car is full of smoke from inside. He tried to open the door but it was locked, then he tried to open the window. The windows were also locked. He tried everything to open the lock of the door but unfortunately, nothing is worked. One nice person was passing from there. He broke the glass of the window and took out my uncle and his wife from the car. They had suffocated a lot but thanks to god that no one is harmed much. Then the car was examined and got the result why this happened. The reason was “Work done in the aftermarket”. 

My reason for telling this incident is Aftermarket work is so risky in terms of safety . That’s why our government also not giving lots of freedom to car modifiers. One another reason for not installing IRVM, Child lock, or any electrical system is the warranty. Any cutting in wires or improper connecting can cause you a loss of your warranty. I think this is the most important rule of car modification.

4.Car Modification rules for Alloy wheels

One of the most famous car modifications in India is changing your regular car wheels with alloy wheels. Do you know alloy wheels improve your car’s performance? But if we talk about the rules about alloy wheels that are simple and similar to tires rules which I have discussed earlier.

 You can use alloy wheels of the upper variant provided by the car company. There are lots of different types of alloy wheels present in the aftermarket as well. Oversized alloy wheels are not legal in India and not preferable as well.
