The nine ITV vehicle-safety-testing centres in Malaga province must clear a 150,000-vehicle backlog when they reopen on Monday.
The website to book an appointment crashed when it reopened on Thursday morning and it remains to be seen how these centres will be able to keep up with demand after almost two months of the state of alarm.
Those whose ITV has expired must register on https://notificaciones.veiasa.es/#/ to be notified about a new appointment.
The Spanish Association for ITV centres (Aeca-ITV) is calling for the Industry ministry to extend the validity of certificates for at least three months as centres will struggle to clear this backlog, especially with changes that need to be implemented to protect users' safety.
Screens have been installed, only those with an appointment can be present (wearing a mask) and during the test itself, the inspector won't be allowed inside the vehicle so the driver will have to carry out certain parts under instruction.
