The cargo transportation in Brazil is predominantly done by road, instead of any other means of transportation. It represented more than 35% of the total amount of money spent on goods transportation on that South American country during 2005. Several factors should be taken in consideration in the final cost of this service. We can highlight, for example: poor road quality, cargo robbery, theft of tires, fuel stealing, road accidents, etc. These costs are always reassigned to the final customers. Among that list, one of main factors for increasing transport costs in Brazil is the illicit fuel deviation.
