Transportation Funding Frequently Asked Questions

What are Idaho’s vehicle registration rates?
One- to two-year-old vehicles are $48, three- to six-year-old vehicles are $36 and vehicles older than six years are $24. Ada County adds $23.83 in county, mailing and plate fees to the state registration fee.

What is the fuel tax in Idaho?
Idaho’s fuel tax has remained at 25 cents per gallon* since 1996. A federal fuel tax of 18.4 cents per gallon has been in effect since 1993.
* An additional 1 cent per gallon is added for the Petroleum Clean Water Trust Fund when the fund drops below $25 million. The fee is removed when the fund has over $35 million. The current fee has been in effect since 10-1-07.

How does Idaho compare to other states in fuel taxes?
Idaho ranks number 22 when compared to other states in fuel taxes.

What condition are our roads in? Our bridges?
One out of every five miles of state highway pavement is deficient. Bridges are designed with an approximate 50-year life span. About 50 percent of Idaho’s bridges will be 50 years or older within the next 10 years.

What happens if we don’t invest?
Without an increase in transportation funding in the next three years, the Idaho Transportation Department will no longer be able to improve safety – the department’s highest priority, fund pothole patching and snowplowing, and provide matching funds to obtain the federal dollars used for most of Idaho’s highway projects.

How much do we need?
The Idaho Transportation Board has determined that Idaho needs a minimum of $240 million in additional funding each year to address the state’s increasing transportation funding backlog.
