All vehicles in Spain must pass their ITV (inspección técnica de vehículos or technical inspection of vehicles) when over a certain age. This process is only as complicated as you make it and generally quite straightforward. All you have to do is make an appointment, turn up on time and then more often than not, wait in line for ages. There is only one center on the island. Remember to have your license plate number ready when you ring for an appointment.
Address: Carretera Sant Miquel, KM.2 (the main road from Ibiza towards Santa Gertrudis)
