INDIANAPOLIS — Hoosiers are changing the way they drive and the state may have to change how it pays for roads.
In a meeting with lawmakers this week, INDOT said it is facing "a fiscal cliff."
Significant funds for the highway department come from the state's gas tax. As Hoosiers buy more fuel-efficient and all-electric cars, they buy less gas.
Eighty-two percent of state road funding comes from fuel taxes.
INDOT estimates by 2040, the drop in gas sales could cost the department $150 million every year.
There are charges for electric vehicles, but all of that money goes to Community Crossings matching grants for smaller towns.
Those funds are a tiny part of the funding now, but as electric car sales go up, so could the impact.
