Detailed Breakdown:

• North Dakota: Begin your journey on I-94 West. Maintain vigilance for changing speed limits and road conditions.

Compliance & Permits

It is the driver's responsibility to ensure they are compliant with all federal and state regulations.

• Weigh Stations & Ports of Entry: Expect weigh stations along I-94 in North Dakota and Montana. I-90 in Montana and Idaho will also have active weigh stations. Be prepared to stop and comply with all directions. Common Montana weigh stations are located in Wibaux, Hardin and Missoula. Idaho weigh stations are located in Lewiston and Huetter.

Risks & Hazards

This route presents various risks, particularly related to weather and terrain. Careful planning and preparation are crucial for a safe trip.

• Seasonal Weather Risks:

  • Winter (October - April): Expect severe winter weather, especially in Montana and Idaho. This includes heavy snow, ice, and blizzard conditions. Mountain passes can become treacherous or temporarily closed. Always check road conditions before departing and be prepared to chain up.
  • Summer (June - August): Extreme heat can be a factor, particularly in lower elevations. Monitor tire pressure and engine temperature to prevent breakdowns. Wildfires can also create visibility issues and road closures.
• Mountainous Terrain: The Rocky Mountains along I-90 in Montana and Idaho present challenging driving conditions. Be aware of steep grades, sharp curves, and reduced speed limits. Use lower gears when descending to avoid brake failure.
