Compliance & Permits

Navigating state lines means understanding various regulations. Here are some key considerations for this Missouri to Arizona run:

• Weigh Stations & Ports of Entry: Expect to encounter weigh stations along both I-44 and I-40. Key states include Missouri, Oklahoma, Texas, New Mexico and Arizona. Common locations include:

  • Missouri: Various locations along I-44. Pay attention to signage for opening and closing times.
  • Oklahoma: Ports of Entry along I-44.
  • Texas: Multiple weigh stations along I-40, often near state lines.

  • New Mexico Weight Distance Tax (NM WDT): While not a guarantee, this might become applicable for heavier loads exceeding specific weight limits on New Mexico highways. Always check for the latest regulations.

Always ensure your truck meets all federal and state safety requirements, including proper lighting, tire condition, and secure load. Be mindful of hours-of-service regulations.

Risks & Hazards

This route presents several seasonal weather-related challenges:

• Winter (November - March): Ice and snow are potential hazards along I-44 and I-40, especially in Missouri, Oklahoma and New Mexico. Be prepared for chain requirements and reduced visibility. Check weather forecasts frequently.
• Summer (June - August): Extreme heat is a significant risk in Arizona and New Mexico. Tire blowouts become more common on overheated roads. Ensure tires are properly inflated and take regular breaks to prevent driver fatigue. Consider running early or late in the day to avoid peak temperatures.
• Monsoon Season (July - September): Arizona experiences a monsoon season characterized by sudden, intense thunderstorms, flash flooding, and dust storms. Reduce speed and increase following distance during these events. Visibility can drop dramatically in dust storms; pull over and wait for conditions to improve if necessary.
