A change made to a truck that is already registered: when is it considered a modification (reforma) of the vehicle?

Question

DentroTest · Accepted Answer

A vehicle modification (reforma), according to Royal Decree 866/2010, which regulates its processing, is any change, replacement, intervention, addition or removal made to an already registered vehicle that changes any of the characteristics indicated on the roadworthiness test (ITV) card or is liable to alter the regulatory requirements applicable to its type approval. That is why what is already included as standard in the type approval and does not alter any data on the ITV card is not a modification, nor is what is done only at the factory before registration. Major modifications are regularized before the competent body of the administration in matters of industry (General Vehicle Regulations, Article 7(2)).
