What is vehicle alteration?
Vehicle alteration generally means a structural change that affects a vehicle's basic features or changes particulars that need to be reflected in its Certificate of Registration (RC). The process is governed principally by Section 52 of the Motor Vehicles Act, 1988, together with applicable Central Motor Vehicles Rules, notifications, technical standards and State/UT transport requirements.
Latest legal position under Section 52
Section 52 of the Motor Vehicles Act, 1988 restricts an owner from altering a motor vehicle so that the particulars in the RC are at variance with those originally specified by the manufacturer, except where the Act, prescribed conditions or an applicable approval/notification permits the alteration.
Permitted modifications may include prescribed conversion or retrofit arrangements, subject to the applicable specifications, approval conditions and technical requirements. A financed or hire-purchase vehicle may also involve consent requirements under the Act.
Because technical approvals and State/UT procedures can differ by alteration type, always check the service options and instructions displayed for your registration number on the official VAHAN portal before modifying the vehicle.
Before you apply
- Confirm that the proposed alteration is permissible under the Motor Vehicles Act, applicable rules, notifications and technical standards.
- Ensure the vehicle's registration record and registered mobile number are available for authentication.
- Keep the existing RC, valid insurance and other documents requested by the portal/RTO ready.
- Where applicable, obtain manufacturer, authorised installer, test agency, financier or other prescribed approval/certificate before submission.
- Do not rely on an online payment receipt as final approval of the physical alteration.
