The Route: Montana to South Dakota

This guide outlines a common and efficient route for commercial truck drivers traveling from Montana to South Dakota. Please consult your specific load requirements, origin/destination points, and company policies when planning your trip.

The primary Interstate Highways used for this route are I-94 and potentially I-90 depending on your specific origin and destination.

• From Western Montana (e.g., Missoula): You would likely take I-90 East to Billings. In Billings, merge onto I-94 East towards South Dakota.
• From Central Montana (e.g., Billings): You'll already be on I-94 East heading directly towards South Dakota.
• From Eastern Montana (e.g., Glendive): I-94 East will be your primary route into South Dakota.

Major cities you will pass near along I-94 include Miles City, MT and Dickinson, ND (just West of the South Dakota Border). Once in South Dakota, you will pass by Spearfish, Sturgis, Rapid City, and Murdo before reaching the eastern part of the state.

Compliance & Permits

Navigating state and federal regulations is crucial for compliance.

• Weigh Stations and Ports of Entry: Expect to encounter weigh stations along I-94 in both Montana and South Dakota. Be vigilant for signage indicating whether the stations are open. Remember to maintain accurate logs (ELD compliance is mandatory) and be prepared for inspections. Exact locations change, so check the FMCSA website or trucking apps for up-to-date information.
• Permits: While neither Montana nor South Dakota currently require specific distance or weight permits like the NY HUT or KYU, ensure you have all necessary federal permits and licenses, including IFTA (International Fuel Tax Agreement) registration and IRP (International Registration Plan) credentials if applicable for interstate travel. Also, review the size and weight restrictions for each state before your trip. Overweight or oversized loads will require specific permits, which must be obtained before entering the state. Consult with your dispatch or permit service for any specific requirements based on your load.

Risks & Hazards

Be aware of potential hazards during your trip to ensure safe travels.

• Seasonal Weather: This route is particularly susceptible to seasonal weather extremes. Winter brings significant risks of heavy snow, blizzards, and icy road conditions, especially in Montana. Be prepared for chain requirements and potential road closures. In spring and summer, be aware of strong winds and potential thunderstorms.
• Wildlife: Deer and other wildlife are prevalent along I-94, particularly at dawn and dusk. Exercise caution, especially in rural areas, and reduce your speed accordingly.
• Wind: High wind warnings are common, especially in the open plains of both states. These can cause stability issues for high-profile vehicles. Check weather reports frequently and adjust your speed or route as necessary. Pay close attention to digital signs and weather reports for high wind advisories and warnings.
