Frequently Asked Questions

Are there any tolls anywhere in Idaho?

No, Idaho has zero toll roads, bridges, tunnels, or any other toll facilities. The Idaho Transportation Department officially confirms this and actively warns against toll scams targeting residents.

Will Idaho ever implement toll roads?

While Idaho law provides toll road authority dating to the 1960s, there are currently no plans or legislative proposals for toll implementation. The 2008 Senate committee rejection of toll proposals and continued commitment to traditional funding suggest tolls remain unlikely.

What about National Park entrance fees - are those tolls?

National Park entrance fees are not tolls - they're admission fees to federal facilities. Sometimes mapping software incorrectly shows these as "toll roads," but they're separate from highway tolling. Park fees apply to specific recreational areas, not road usage.

Do I need a transponder for traveling through Idaho?

No transponders are needed for Idaho travel. However, if you're traveling to neighboring states with tolls, you may want a transponder for those areas. Idaho itself requires no electronic toll equipment.

What should I do if I receive a toll violation notice claiming to be from Idaho?

It's a scam. ITD does not issue toll fines because Idaho has no tolls. Do not click links or provide personal information. Report the scam to your mobile carrier and the Federal Trade Commission.
