Officials in Michigan are thinking about replacing gas taxes with “usage charges.”

As the auto industry shifts to electric vehicles, a cut into tax revenues for road repairs is expected.

Bridge Michigan says with fuel taxes expected to decline by millions in the future years, Governor Whitmer’s budget signed last week supports exploring the idea of charging motorists for each mile driven rather than each gallon of gas consumed.

The state plans to spend over $5 million to survey 20,000 Michigan residents this fall while studying what type of impact a road usage charge system may have.
