Do I Need to Pay Tolls in Montana? 2026 Update
No, you do not need to pay any tolls to drive in Montana. The state has no toll roads, bridges, or tunnels anywhere within its borders. You can drive the entire 552-mile length of I-90 across Montana without paying a single toll.
Key Reality: Montana is one of only 15 US states that maintain completely toll-free transportation networks. The state funds its road system through gas taxes ($0.315/gallon), vehicle registration fees, and federal grants.
2026 Update: Montana Department of Transportation manages roughly 25,000 lane miles of highways and bridges using traditional funding methods. The IIJA (Infrastructure Investment and Jobs Act) federal funding program — which provided $3.1 billion to Montana for highway and bridge investments over five years — concludes in federal fiscal year 2026, its final year. MDT's FY 2026 appropriation authority totals approximately $134.4 million in state special revenue funds. No toll roads are planned. The Montana DOJ's Office of Consumer Protection issued a fresh scam warning in February 2026 about fraudulent text messages impersonating the Montana Motor Vehicle Division and demanding payment for fines or tolls — Montana has no toll roads and MDT never sends payment demand texts.

Toll Discussion:

Funding Status:

- IIJA concluding in FY 2026 — Congress considering a new federal surface transportation reauthorization to replace it beyond September 30, 2026
- Construction cost inflation and EV adoption remain long-term funding concerns for MDT, but no toll road response planned
⚠️ 2026 Scam Alert: Fake Toll & MVD Text Messages Targeting Montana
Montana has no toll roads, yet residents continue to receive fraudulent "smishing" (SMS phishing) text messages demanding toll payments. In May 2025, MDT reported receiving over 200 calls in a single week about these scam texts. The Montana DOJ's Office of Consumer Protection issued a further warning in February 2026 about scammers now impersonating the Montana Motor Vehicle Division (MVD) by text, demanding payment for fines or traffic tickets.
Key facts:
- Montana has no toll roads — any text claiming you owe toll dues is always fraudulent
- MVD does not send texts asking for money for unpaid tickets or tolls
- MDT will never text you demanding payment of any kind
- Scam texts may also arrive from other states' DOTs — if you receive any suspicious toll text, treat it as a scam regardless of which state it claims to be from
- Texts typically threaten vehicle suspension, legal action, or credit damage to create urgency — do not react quickly
What to do: Do not click any links. Do not provide personal or financial information. Report scam texts to the Montana Department of Justice's Office of Consumer Protection at dojmt.gov. You can also report to the FTC at reportfraud.ftc.gov and forward the text to 7726 (SPAM) on your mobile carrier.

Frequently Asked Questions
Will Montana ever have toll roads?
Highly unlikely in 2026 or near future. Montana has robust funding through gas taxes and federal grants. The state maintains over 25,000 lane miles toll-free and shows no serious interest in tolling. While MDT is studying long-term alternatives to the fuel tax (such as mileage-based user fees and EV registration fees), none of these involve toll roads on existing highways.
Do I need any special equipment for Montana highways?
No electronic toll tags, transponders, or special equipment required. Standard vehicle registration and driver's license are sufficient.
No hidden fees. You pay gas taxes at the pump and vehicle registration fees annually, but no usage-based tolls anywhere in the state.
How does Montana compare to neighboring states?
Montana is similar to neighboring North Dakota, South Dakota, Wyoming, and Idaho — all toll-free in 2026. Alberta, Canada (to the north) is also toll-free.
What about winter driving in Montana?
Montana highways are maintained year-round at no additional toll cost. Budget for possible tire chains, winter gear, and emergency supplies during winter months.
