To park in these places it is mandatory to place inside the vehicle, next to the windscreen and in a clearly visible location, the corresponding proof of payment by means of a ticket, card, etc., showing the time at which parking begins and when it must end, after which parking is considered prohibited. Failure to do so may result in a fine and also immobilisation of the vehicle.
