Additionally, Kentucky and North Carolina adjusted their variable-rate gasoline tax formula during this time in order to preserve or increase revenue for roads, bridges, transit, and more (Vermont and Utah also adjusted their recently-approved formulas during this time).

Looking back to 1997, 30 states and the District of Columbia have increased motor fuel related taxes 49 times.
