AREA C pratically you've to pay a ticket to acess if you're motorized the ZTL(limited traffic zone)of the city everytime.It correspond to the mid and center of the city area(very big part of the town) even if you want come back home.It's exempted from the middle age tax only can buy cars fitted with the last anti pollution requirements,pratically the lasts model no more aged than 2 or 3 years,if you're poor and you can't change car,is your own facts,nobody is interestedMore the requiriements change form year to year so you can't have the same car for many times.I never seen before a similar and social inequality in a civil country and modern times.The first anti pollution charge was activated in 2008 and from 2012 it was increased as ticket cost you've to pay.Beware the penalty in case you forget or for not paymenet at all is very high.
