Frequently asked questions

Vehicle transformation refers to any alteration of its original characteristics, such as:

  • Modifications to the structure or bodywork

  • Changes to the engine or suspension system

  • Energy conversion (e.g., LPG or CNG)

Adaptations for reduced mobility These changes require technical validation and legal approval before being executed.

Yes. The transformation should only be initiated after prior approval of the technical plan by the IMT (Institute for Mobility and Transport). Any alteration made without approval may render the legalization of the vehicle unviable.

Among the most frequent transformations are:

  • Bodywork alteration (e.g., from cargo to passenger)

  • Replacement or modification of the engine

  • Conversion to Compressed Natural Gas (CNG) or Liquefied Petroleum Gas (LPG)

  • Adaptation for persons with reduced mobility or special functions (e.g., ambulances)

Yes. Depending on the transformation, the following may apply:

  • Taxes such as ISV (Vehicle Tax)

  • Update of the Single Circulation Tax (IUC)

  • Administrative fees regarding the analysis and approval of the process with the IMT

Transformation without prior approval may have serious legal implications, such as:

  • Prohibition of vehicle circulation

  • Seizure of documents

  • Obligation to revert the modifications made

  • Fines and other legal sanctions

The transformation plan must be prepared by qualified technicians and validated by an Engineer registered with the respective Professional Order. At TDS Auto, we ensure that all technical drawings, descriptive memoranda, and remaining documents comply with the requirements demanded by the IMT for approval of the transformation.
