MANDATORY FILINGS
The Route: Utah to Arizona
This guide outlines a common and efficient trucking route from Utah to Arizona. This route primarily leverages Interstate highways for optimal travel time, but drivers should always verify conditions and adapt as necessary.
- Starting Point: Salt Lake City, UT (approximate)
- Ending Point: Phoenix, AZ (approximate)
I-15 South (Utah): Begin on I-15 South from your origin point in Utah. This is the primary north-south artery through the state. Ensure your vehicle is prepared for potential elevation changes, especially during colder months.
Arizona State Line: Continue south on I-15, crossing the Utah-Arizona state line near Mesquite, Nevada (though you will not enter Nevada).
I-15 South (Arizona): Continue south on I-15 through the northwest corner of Arizona. This stretch is relatively short.
I-15 to US-93 South: Exit I-15 and merge onto US-93 South. This is the main route into the Phoenix metropolitan area.
Phoenix Arrival: Continue on US-93 South towards Phoenix. US-93 may turn into local routes as you near Phoenix depending on your specific destination. Plan accordingly.
Compliance & Permits
- Weigh Stations & Ports of Entry: Be prepared for weigh stations along I-15 in both Utah and Arizona. Common locations include, but are not limited to:
- I-15 SB near St. George, UT.
- I-15 NB near Littlefield, AZ (just north of the Nevada state line).
- Permits: While general oversize/overweight permits may be needed depending on your load, there are no specific state-required mileage or weight-distance tax permits required for routine operations in either Utah or Arizona based on a standard tractor-trailer configuration. Oversize/overweight permits are obtained based on size/weight thresholds.
- Always confirm with the state DOT for the most current regulations, especially concerning oversize or overweight loads.
- Ensure all IFTA and IRP requirements are current and compliant.
Risks & Hazards
- Seasonal Weather - Utah: Winter conditions on I-15 in Utah can be severe. Expect snow, ice, and reduced visibility. Carry chains and be prepared for delays. Check weather forecasts before and during your trip. Spring and fall can bring sudden temperature changes and potentially flooding.
- Seasonal Weather - Arizona: Extreme heat is a significant concern, especially during summer months (June-August). Regularly inspect tires and monitor engine temperature. Ensure your cooling system is functioning correctly. Dehydration is a real threat; carry sufficient water and take breaks to hydrate. Monsoon season (typically July-September) can bring flash floods and dust storms that reduce visibility.
- Wildlife: Be aware of the possibility of wildlife crossings, particularly in rural areas. Reduce speed at night.
- Driver Fatigue: The long stretches of highway can contribute to driver fatigue. Adhere to all hours-of-service regulations. Take frequent breaks, and consider using team drivers for longer routes. US-93 is a known hazard for drowsy drivers, especially at night.
