São Paulo is the capital of the state which bears the same name. It is the largest city in Brazil with over 20 million people inhabiting the metropolitan area. Partly because of this, the city presents difficulties in gaining rides to the place you want to go. There are generally 2 freeways that head in that direction due to the large volumes of traffic.
To Interior of São Paulo State, Brasilia & Goiania Make your way to Jundiai by train. From the centre of Sao Paulo go to Luz Station and get the A train. The fare is around R$ 2.60 Once you get to Jundiai station you will need to walk or get a bus through the city to either one of the Rodovias Anchieta or Bandeirantes. Their is a posto de gasolina and truck stop a little north of the city on the Rodovia Anchieta. Lunchtime is good to find a caminhoneiro (truckdriver) if not there are always truckdrivers trying to fix their trucks
There again exist two freeways (rodovias) out of Sao Paulo in the direction of Rio de Janeiro. One is Presidente Dutra which heads closer to the Airport near Guarulhos, along here there are many posto de gasolina. For something different head to the Ceasa (Truck Depot) in Guarulhos. From here its possible to get a truck anywhere in Brazil, the size of the place is overwhelming at first.
