Legalization of Vehicle Modifications

VEHICLE MODIFICATIONS HOMOLOGATIONS ONLINE

 

The homologation or legalization of vehicle modifications is the preliminary step to the authorization that determines that your vehicle is in optimal condition for circulation. Without homologation, you will not be able to obtain a positive result in the ITV (Spanish vehicle inspection). 

Any modification that involves a change to the vehicle and alters its characteristics must be properly homologated. Having these modifications and the car homologated will allow you to obtain a satisfactory result in the ITV. Now you can obtain this homologation online.

What is a vehicle modification?

 

First, let's define what a modification is. According to Royal Decree 866/2010, it is any modification, replacement, action, incorporation, or deletion made to a vehicle after its registration (for light trailers after being authorized to circulate) that changes any of its characteristics.

Importing a vehicle from outside the EU

 

If you have purchased a vehicle from a non-EU country and want to import it for circulation in our country, it will be necessary to re-register it in Spain after passing through Customs. To do this, you must complete the process at www.ereformas.es and you will be able to import the vehicle from abroad. 

Trailer hitch homologation 

 

As of today, the installation of a trailer hitch on our vehicle is considered a significant modification, so we must also take it into account and homologate the trailer hitch. To carry out this homologation process, we need the workshop certificate from the installer, the homologation code of the hitch, and a conformity report. You can do it on our ITV reforms website www.ereformas.es.

EXAMPLES OF VEHICLE MODIFICATIONS:

  • Installation of a trailer hitch.

  • Modification of the exhaust pipe.

  • Replacement of the bumper.

  • Adaptation of the vehicle for people with reduced mobility.

LEGALIZATION OF THE MODIFICATION IN ITV

Legalization is the required step in the ITV and ensures that the modification complies with circulation standards. In the ITV, we certify that those elements previously homologated for the vehicle in question have been installed in compliance with specific criteria.

If everything is correct, we will note the modification on the vehicle's technical inspection card, at which point the modification can be considered legalized.

CAN I HOMOLOGATE AN ITV MODIFICATION ONLINE?

To easily and simply carry out your modification or homologation, you can do so through our portal www.ereformas.es where you will find all the essential information and we will guide you through the vehicle homologation process online.

INSPECTION OF A MODIFICATION

The steps to receive the homologation certificate for vehicles are as follows:

 

  1. Documentary inspection: it is checked that the documents provided are adequate according to current regulations. Normally these are the following, although they may vary depending on the type of modification.
  • Vehicle documentation: technical sheet and registration certificate.
  • Technical project: a report made by an engineer detailing the purpose of the modification, that is, all the details related to its realization. Normally, the technical project is necessary when the modification requires technical analysis and calculations.
  • Conformity report: a laboratory or the vehicle manufacturer certifies that the proposed modification in the technical project can be carried out.
  • Workshop certificate: once the modification is approved, the workshop is the one that applies the modifications to the vehicle and provides the certificate that the work has been completed.
  • Final work report: the engineer who carried out the technical project must prepare a final document approving the entire work. If you are the owner, you must present your ID. If you are not, the person who appears at the ITV station must go with their ID and authorization from the vehicle owner to process the modification.
  1. Physical inspection: the modifications made are evaluated thoroughly to ensure that they have been carried out according to the documentation provided and that the vehicle still meets the minimum safety requirements.

VEHICLE HOMOLOGATION ONLINE

 Introducing www.ereformas.es, a useful tool that allows you to legalize the modification of your vehicle online quickly and without complications. Visit our ITV stations with the utmost peace of mind. What documentation do I need to submit according to my modification? In the case of modifications, this is the specific documentation you need to submit:

  • Conformity report
  • Workshop certificate
  • Technical project
  • Final work certificate
  • Additional documentation if the vehicle belongs to an INDIVIDUAL or COMPANY:
  • ID of the vehicle owner
  • Technical sheet (ITV card)
  • Registration certificate
  • It is advisable to bring proof of valid mandatory insurance.
  • Authorization if the requester is not the owner or is in the name of a company.

What do I have to do after legalizing my modification?

Do I need to go to traffic? In case the modification involves any changes in the registration certificate of your vehicle, you must go to Traffic to report the modifications and have them reflected in it. What happens if I do not legalize a modification? It is important to legalize modifications because it is a reason for an economic sanction, and the vehicle can even be immobilized. Furthermore, in case of an accident, insurance companies may refuse to compensate for damages, even if the vehicle is insured against all risks.
