A monitoring system that determines vehicle position and fuel consumption in a jurisdiction, and jurisdiction crossings. The system includes a vehicle having a fuel reservoir from which fuel is consumed as an energy source. The system also includes a positioning system for generating the present position information of the vehicle. The information includes latitude and longitude data points. Additionally, the system includes a fuel monitoring device in the fuel reservoir, whereby the fuel monitoring means generates information including the present level of fuel in the fuel reservoir. Also, a data collection device for collecting the present position information and the present level of fuel information. Finally, the system includes a processor located at a remote site from the vehicle, the processor receives data from the collecting device. The processor determines when the vehicle crosses a jurisdiction border and computes the fuel consumption in the jurisdiction, the fuel consumption data can then be later used to compute the fuel tax.
