Summary –
The bill would require the use tax revenue and the six and five-tenths percent sales tax revenue from new or used retail sales of a vehicle, including private-party sales, to be used for transportation projects, maintenance, and repairs, and for reducing the reliance on transportation-related debt obligations. (It would not include the revenue from car rentals.)

The bill would begin transferring an additional 25% of the sales tax revenue to a new account dedicated to these purposes in the 2027 fiscal year; then increase the percentages by 25% each year, beginning to transfer all the revenue in fiscal 2030. The use tax would be transferred in the same way, except that it’s described as the transfer of “additional” percentages. (I don’t see why, since it’s all going into a new account.)
