Some things can be apportioned. In those cases, the more use, the more the user should pay. With roads there is also a function of weight. Heavier vehicles wear out the roads more than lighter vehicles, and this should be taken into account. Of course there are ramifications.... the higher road use tax of heavy trucks will be translated into higher prices for whatever they''re hauling, but ultimately it is the most fair.<quoted text>
So, say, a motorcycle should pay the same as a double-bottom semi to use the Ohio Turnpike?
Things that cannot be apportioned should be paid equally by all those who the service is for. Military, for example.
Yet other things are a combination... Fire departments for example have a standby cost, where they benefit all, and run costs, where they are benefiting a specific person. Should be (and is starting to be in many communities, who are for example charging your insurance for EMS runs) charged accordingly.
