Some of the taxes you pay on gasoline and diesel are meant to be public road use taxes. If you're not burning the gas by driving on a public road, they don't need to be paid. You can apply for a rebate based on how much you burnt off-road (for example, you have a logging truck that burns 10% of its gas on private logging roads). If you have an engine that you use exclusively off-road (such as in farm equipment), you can buy whats called pink diesel or dyed diesel. You don't have to pay the public road use taxes on pink diesel, but it stains your engine. The engine of a vehicle used on public roads can be inspected to see if its ever burned pink diesel, and if it has, you get in trouble.
