Not showing a valid ITV test sticker when your vehicle reaches a certain age could lead to a 200-euro fine. However drivers in Andalucía have faced a predicament for the last month and a half as it has been taking that long to get an appointment at the regional-government-owned testing centres.
The problem is worst for people working in the transport sector as their vehicles need to pass tests up to twice a year.
Now the regional government has dealt with the problem by increasing the amount of staff on temporary contracts. Appointments have been easier to get at testing centres in Malaga province over the last week.
The problem arose when some 400 workers across Andalucía didn't have their temporary contracts renewed at the end of last year.
Unions have said that the problem is structural and that there is a shortage of full-time inspectors and staff, some 50 in Malaga province, which haven't been replaced since a recruitment freeze during the financial crisis a decade ago.
Some drivers had been forced to queue all night to try to get a check without a prearranged appointment.
