Motor vehicles; motor fuel sales tax in certain transportation districts.

Provides that the tax that is imposed on the sales price of motor fuel in Northern Virginia shall be imposed on the regional price of gas, defined and computed as a six-month average price of fuel. The regional price has an initial floor of January 11, 2017. If a newly averaged regional price is higher than the preceding regional price, the tax is imposed on the new regional price, but if a newly averaged regional price is less than the preceding regional price, the higher of the two remains the regional price. If the regional price is at any time equal to or greater than the statewide average wholesale price of unleaded regular gasoline on February 20, 2013, then the tax is imposed on the regional price, which moving forward shall not be less than the statewide average wholesale price of unleaded regular gasoline on February 20, 2013, and shall not be more than a price of $4 per gallon of unleaded regular gasoline. The bill also raises the rate of taxation of motor fuel in Northern Virginia from 2.1% to 3%. The bill also changes the regional gas tax in Hampton Roads from a percentage to a cents-per-gallon tax that decreases as the price of gas increases. The regional gas tax in Hampton Roads would have a floor of $0.05 per gallon and a ceiling of $0.14 per gallon and would be determined on the basis of the average wholesale price of unleaded regular gasoline.
