<s>[INST] The next text is a question of a member of the European parliament:"According to recent information, certain makes (in particular, Chrysler and Kia) of 'people carrier'-type vehicles are now eligible for the lowest (class 1) toll charge when they are used on Portuguese motorways, even though a higher rate continues to apply in the case of other vehicles of a similar design.  The Portuguese Ministry of Economic Affairs apparently once announced that 'people carriers' manufactured at the AutoEuropa plant would also be taxed as class 1 vehicles (in addition to the makes of vehicle which already enjoy that benefit), but this did not actually come to pass.  This difference in toll charges particularly affects larger families, who are more or less obliged to use vehicles of the 'people carrier' type.  In view of the above, would the Commission answer the following questions?  -  Is the Commission aware that, in Portugal, different motorway toll charges exist for 'people carrier'-type vehicles?  -  What view does the Commission take of this situation in the light of the principles of non-discrimination and competition on equal terms within the internal market? Does the Commission not consider this to constitute an infringement of those principles?  -  What action has the Commission taken (or is it intending to take) in order to put an end to this state of affairs which not only constitutes unfair competition but also penalises many large families?"
