The tax amount distributed to the state in the manner provided by RCW 46.68.090, and all moneys accruing to the motor vehicle fund from any other source, less such sums as are properly appropriated and reappropriated for expenditure for costs of collection and administration thereof, shall be expended, subject to proper appropriation and reappropriation, solely for highway purposes of the state, including the purposes of RCW 47.30.030.
