Download Free Authorization Letter to Pass the ITV in Guarda (A) (Word/PDF Template)

If your vehicle is due for its mandatory Spanish Technical Vehicle Inspection (ITV) but you are unable to drive it to the station yourself, do not worry. Spanish law allows a third party—such as a family member, friend, or trusted mechanic—to take your car through the inspection on your behalf. To do this legally at the ITV station in Guarda (A) or any other municipality in Spain, the authorized person must present a signed authorization letter along with specific identification documents. Below, you will find a ready-to-use, legally compliant template that you can easily copy, paste, and adapt for your needs.

Additional documentation required

A signed authorization letter alone will not be enough to get your car through the inspection lines in Guarda (A). The authorized driver must ensure they also bring the mandatory vehicle documents. This includes the original Permiso de Circulación (Registration Certificate) and the Tarjeta de Inspección Técnica (Technical Sheet). Additionally, remember that the vehicle's mandatory civil liability insurance (seguro obligatorio) must be active and up to date, which the station technicians can verify electronically, though carrying proof of payment is always recommended.

As an expert traffic consultant, my top tip is to double-check that the vehicle's taxes (like the municipal road tax, IVTM) are fully paid and that no minor issues—such as blown bulbs or worn-out wiper blades—might cause an unfavorable result. Saving the authorized person from failing a minor check will save you both a second trip to the ITV station in Guarda (A).
