Midwest State Greenlights Heavier Harvest Loads for Farmers
Iowa has issued a harvest-related disaster proclamation temporarily suspending certain registration, permit and fee requirements for eligible agricultural loads transported on the state’s non-interstate highways.
Waiver Covers Non-Interstate Highways
The proclamation was issued as the 2026 grain harvest gets underway across Iowa. State officials cited increased agricultural truck traffic and the need to move crops efficiently during the time-sensitive harvest season.
The suspension applies to qualifying loads transported on all Iowa highways except the interstate system. The proclamation covers divisible loads of soybeans, corn, hay, straw, silage, stover, fertilizer and manure.
According to the proclamation, strict compliance with certain Iowa registration, permit and fee requirements could hinder efforts to collect and transport the harvest in a timely manner.
Weight Limits Still Apply
Eligible vehicles may not exceed 90,000 pounds in gross weight. Loads also may not exceed the applicable maximum axle weight limit by more than 12.5% under Iowa’s primary and non-primary highway weight tables.
The proclamation maintains an absolute maximum axle weight of 20,000 pounds. Drivers must also comply with any posted weight limits on roads and bridges.
The waiver does not apply to interstate travel, and the stated weight restrictions remain in effect for all covered agricultural shipments.
Harvest Activity Increases Across the Midwest
Harvest activity is advancing across parts of the Midwest as warm temperatures accelerate crop dry-down. In Minnesota, the latest USDA crop progress report showed corn at 98% in the dough stage, 85% dented and 24% mature, with 58% of the crop rated good to excellent.
Farmers in southwest Minnesota reported that early harvest activity had begun, although much of the region’s crop was still at least a week from being ready. Dry summer conditions have pushed some maturity groups into a narrower harvest window, increasing pressure on farm and trucking crews.
The Iowa proclamation is intended to help agricultural carriers and producers move eligible commodities during that compressed period while preserving posted road and bridge restrictions.
