(1) Both principal and interest on the bonds issued for the purposes of RCW
47.10.834 through
47.10.841 are payable from the highway bond retirement fund.
(2) The state finance committee shall, on or before June 30th of each year certify to the state treasurer the amount required for principal and interest on the bonds issued for the purposes specified in RCW

(3) Any funds required for bond retirement or interest on the bonds authorized by RCW
47.10.834 through
47.10.841 shall be taken from that portion of the motor vehicle fund that results from the imposition of excise taxes on motor vehicle and special fuels and vehicle-related fees which is, or may be appropriated to the department of transportation for state highway purposes. Funds required shall never constitute a charge against any other allocations of motor vehicle fuel and special fuel tax revenues and vehicle-related fees to the state, counties, cities, or towns unless the amount arising from excise taxes on motor vehicle and special fuels and vehicle-related fees distributed to the state in the motor vehicle fund proves insufficient to meet the requirements for bond retirement or interest on any such bonds.
(4) Any payments for bond retirement or interest on the bonds taken from other revenues from the motor vehicle fuel and special fuel taxes and vehicle-related fees that are distributable to the state, counties, cities, or towns shall be repaid from the first revenues from the motor vehicle fuel or special fuel taxes or vehicle-related fees distributed to the motor vehicle fund not required for bond retirement or interest on the bonds.
