The most important word to know is frenos (brakes). They'll ask you to apply them on the brake test, lightly at first and they'll say mas mas mas and then vale(ok). You'll be asked to apply them again via the speaker when your over the inspection pit. In my experience his is the most dificult part understanding them via the speaker when they're in the pit. The new Amposta itv station is still very quiet at the moment and they offered to take my car through whilst I did the paperwork and paid the fee in the office. Nice and simple. If it fails you have fifteen days to put it right and return for a no fee check on the item and be issued your certificate. Let us know if you need any other info. The great thing about the itv stations in my personal view is they have no agenda vis repairs of a failed item. And the thing it failed on is printed on the form so you just take that to your garage and get them to fix it.
Very simple.
