Vehicle modifications are often made to improve the appearance, performance, or comfort of a vehicle. However, many modifications are illegal if they do not comply with the regulations set by the Motor Vehicles Act and guidelines from the Ministry of Road Transport and Highways (MoRTH). These modifications can compromise safety, environmental standards, and traffic law compliance, leading to penalties for the vehicle owner.
The Motor Vehicles Act and the Central Motor Vehicles Rules (CMVR) specify that any vehicle modification that alters the original structure or performance of the vehicle must be approved by the Regional Transport Office (RTO).
Before any major modification, the vehicle owner must seek approval from the Regional Transport Office (RTO). Failing to do so makes the modification illegal.
Some modifications are permissible, such as installing seat covers, new upholstery, or adding cosmetic accessories, as long as they do not affect the vehicle's safety, performance, or emissions compliance.
If a vehicle is found to have illegal modifications, the owner can be fined. The fine for illegal vehicle modifications can range from ₹1,000 to ₹5,000 for the first offense. The fine can increase if the offense is repeated.
The vehicle owner will be issued a challan (traffic ticket) for the violation. The authorities will typically ask the owner to remove or revert the modifications to comply with the law.
In certain severe cases, if the modifications significantly affect the vehicle’s safety, emissions, or cause a risk to public safety, the vehicle may be impounded until the illegal modifications are corrected.
If the vehicle does not comply with road safety standards due to illegal modifications, authorities may even suspend the vehicle’s registration or refuse to renew it until the vehicle is restored to its legal configuration.
Some modifications, particularly those affecting the braking system, tires, or engine performance, can make the vehicle prone to accidents. In such cases, the driver may be held accountable for causing damage or harm, and more serious legal actions may follow.
Modifications that affect a vehicle’s structural integrity, braking system, or suspension can endanger the safety of the driver, passengers, and others on the road.
Many modifications, especially those that affect the exhaust system or emission controls, can lead to increased pollution and harm the environment. The government enforces strict rules to ensure that vehicles meet emission standards.
Modifications to the exhaust system that cause excessive noise can create disturbance in residential areas, affecting public health and well-being.
Certain modifications, such as excessively dark window tints or blinding headlights, can impair visibility, leading to accidents.
Vehicles that have illegal modifications often fail to meet regulatory standards set by the RTO, which are in place to ensure that vehicles operate safely and efficiently on public roads.
A car owner in Mumbai installs a loud aftermarket exhaust system to enhance the sound of the vehicle. After a routine check by the traffic police, it is found that the exhaust system exceeds the permissible noise levels set by pollution control laws. The owner is fined ₹2,000 and asked to replace the exhaust with one that complies with legal noise regulations.
Before modifying any part of your vehicle, ensure you consult the Regional Transport Office (RTO) and get the required approval for modifications.
Only use certified and approved vehicle parts or accessories for modifications to ensure they comply with safety, emission, and road safety standards.
Always keep in mind the legal limits on modifications, such as exhaust noise, engine capacity, window tint, and lighting to avoid fines or penalties.
If your vehicle already has illegal modifications, it is advisable to remove or correct them as soon as possible to comply with the law and avoid penalties.
While vehicle modifications can enhance the appearance and performance of a vehicle, they must comply with the regulations set by the authorities to ensure road safety, environmental standards, and public health. Illegal modifications, especially those that compromise the safety of the vehicle or others on the road, can result in fines, penalties, or even the impoundment of the vehicle. It is important for vehicle owners to adhere to the legal limits and seek approval from the Regional Transport Office (RTO) before making significant changes to their vehicles.
