The AEMA-ITV association has published clarifications on passing the technical inspection (ITV) for different types of tourist transport. For motorhomes (category M), the frequency matches that of passenger cars: first inspection after 4 years, then every 2 years up to 10 years, then annually. Caravans (trailers) over 750 kg pass ITV for the first time after 6 years, then every 2 years. Campers (vans category N1) — first inspection after 2 years, then at 4 and 6 years, then annually up to 10 years, then every six months. Special attention is paid to documentation on conversions, including gas equipment.
According to another source, in Spain the ITV rules have been updated, applying differently to motorhomes (category M) and campers (category N). Motorhomes pass the first ITV 4 years after registration, then every 2 years, and after 10 years annually. Campers are required to pass ITV annually from registration, and after 10 years every 6 months, increasing costs and time. Sources differ on camper frequency: according to AEMA-ITV, first inspection after 2 years, then at 4 and 6 years, while the other source says annually from registration.
