Kansas IFTA Calculator

Kansas is a major through-state on the I-70 corridor connecting Kansas City to Denver, and a significant agricultural origin state for wheat, sorghum, cattle, and pork. I-70 runs straight across the state for 424 miles — a long, flat, often wind-swept drive through some of the most exposed terrain in the country. I-135 connects Wichita north to Salina and I-70. I-35 runs diagonally from Kansas City southwest through Wichita to Oklahoma — the Kansas Turnpike segment of I-35 through the eastern portion of the state uses toll booths. Wichita is the largest city and houses significant aircraft manufacturing (Cessna, Spirit AeroSystems) that generates specialized freight.

Kansas's IFTA rate of $0.260 per gallon is among the lower rates in the central US. Oklahoma at $0.190 to the south and Missouri at $0.197 to the east are cheaper. Nebraska at $0.290 and Colorado at $0.205 are in a similar range. For eastbound drivers on I-70, fueling in Kansas before entering Missouri doesn't save much, but filling up before entering Iowa or Illinois from the north saves significantly.

Standard weight limits are 80,000 lbs. Kansas has a statewide permit system for oversize and overweight loads managed through the Kansas Turnpike Authority and KDOT. Wind turbine component hauling has become a major permit load activity in Kansas, with specialized routing requirements for blade and tower section transport across the western plains.

Weigh stations on I-70 at Topeka, Salina, and near the Colorado border at Kanorado are regularly staffed. Wind on the Kansas plains can make driving difficult for high-profile trailers, especially box trucks and curtain-sides — west Kansas sees sustained winds exceeding 40 mph that can affect steering and fuel economy significantly. For IFTA compliance, Kansas's straightforward rate structure makes filings relatively clean, but track Kansas Turnpike mileage separately from open highway mileage if you need to reconcile toll records with fuel logs.
