Compliance & Permits

Navigating the legal requirements is critical for smooth operations. The suggested route crosses multiple state lines, each with its own specific regulations.

• Weigh Stations/Ports of Entry: Drivers should anticipate and prepare for inspections at the following locations (among others):

  • Arizona: Along I-17 and I-40, multiple weigh stations. Consult AZDOT resources for specific locations.
  • New Mexico: Ports of Entry along I-40 and I-25. Look for signage indicating inspection requirements.
  • Colorado: Weigh stations are common along I-25.
  • Wyoming: Ports of Entry along I-25 and I-90.
  • Montana: Weigh stations located on I-90 as you enter and traverse the state.

• Permits: While this route avoids toll roads necessitating IRP (International Registration Plan) and IFTA (International Fuel Tax Agreement) compliance is always mandatory. Certain commodities, such as oversized loads or hazardous materials, may require additional permits from the individual states.

  • New Mexico Weight Distance Tax (NM WDT): If your vehicle's gross weight exceeds 26,000 pounds, you will need to comply with the NM WDT. This involves registering with the state and paying taxes based on miles traveled within New Mexico. Check NM taxation and revenue department website for details.
  • Oversized/Overweight Permits: Loads exceeding standard size and weight restrictions will require permits from each state along the route (Arizona, New Mexico, Colorado, Wyoming, and Montana). Apply well in advance of travel, as the permitting process can take time.

Risks & Hazards

This route presents a variety of seasonal weather risks that drivers must be prepared for.

• Summer: Extreme heat in Arizona and New Mexico poses a significant risk. Ensure your vehicle is properly maintained, especially the cooling system. Stay hydrated and take frequent breaks to avoid heat exhaustion. Tire blowouts are also more common in hot weather. Wildfires in the western states can cause road closures and reduced visibility.

• Winter: Heavy snow and ice are major concerns in the Rocky Mountain regions of Colorado, Wyoming, and Montana. Chains may be required, and road closures are possible. Check weather forecasts frequently and be prepared for delays. Mountain passes can be particularly treacherous.

• General Hazards: High winds are common throughout the Great Plains, especially in Wyoming. Secure your load properly and be prepared to adjust your speed. Wildlife, including deer and elk, pose a risk, especially at dawn and dusk. Construction zones are common, so be aware of reduced speed limits and lane closures. Always maintain a safe following distance and be vigilant.
