Commrs., 332 U.S. 495, 503-504 (1947). Here was sustained a State statute imposing a flat tax of $10 annually upon each vehicle operated by a motor carrier over the State's highways, and a fee of one half of one per cent of the carrier's gross operating revenue from its operations within the State, with an annual minimum of $15 per vehicle, in consideration of the use of the highways and in addition to all other motor vehicle license fees and taxes. This was held, as applied to a carrier engaged solely in interstate commerce, not to burden such commerce unconstitutionally, although the proceeds went into the State's general fund subject to appropriation for other than highway purposes. (Opinion by Rutledge, J., all concurring.) While a "State may not discriminate against or exclude such interstate traffic generally in the use of its highways, * * * [it is not] required to furnish those facilities to it free of charge or indeed on equal terms with other traffic not inflicting similar destructive effects. * * * Interstate traffic equally with intrastate may be required to pay a fair share of the cost and maintenance reasonably related to the use made of the highways."
