Arkansas IFTA Calculator

Arkansas occupies a central position in the mid-South freight network, and its importance to trucking far exceeds its size. The state is home to the Walmart supply chain headquarters in Bentonville, which generates constant freight demand for supplier deliveries from across the country — the Northwest Arkansas region alone produces a disproportionate share of truckload freight for carriers hauling consumer goods. I-40 bisects the state east-west connecting Fort Smith to Memphis, while I-30 cuts diagonally from Texarkana to Little Rock and continues toward Memphis on I-40. I-55 runs along the Mississippi River through the Delta region, and I-49 connects Fort Smith north to Kansas City — this corridor has seen massive growth tied to Walmart and poultry industry shipping.

Arkansas's IFTA rate of $0.285 per gallon is a middle-ground rate. Missouri to the north at $0.197 and Louisiana to the south at $0.200 are significantly cheaper, so southbound or northbound drivers should plan fuel purchases across the border when routes allow. Oklahoma at $0.190 is the cheapest neighboring state for westbound drivers approaching Fort Smith.

Weight limits are standard 80,000 lbs on interstates, but Arkansas has seasonal weight restrictions from January through March on many secondary roads due to freeze-thaw damage — these restrictions significantly limit weight allowances on certain state highways to as low as 72,000 lbs. Always check the Arkansas Department of Transportation's posting schedule before venturing onto non-interstate routes in winter.

The weigh stations on I-40 near Alma (westbound) and at the Tennessee border (eastbound) are active and use WIM sensors. The I-30 station near Benton is also frequently staffed. Arkansas enforces agricultural inspections particularly for loads entering from Texas and Oklahoma through certain checkpoints. For IFTA filing, note that Arkansas maintains a separate Motor Fuel Tax section within the Department of Finance and Administration — your base state IFTA filing still covers Arkansas miles, but double-check your mileage logs if you run the Walmart dedicated lanes in the Northwest corner frequently.
