About Illinois Oversize/Overweight Permits
Any vehicle or load that exceeds Illinois’ legal size or weight limits on a state-jurisdiction highway requires an Illinois oversize/overweight permit from the Illinois Department of Transportation (IDOT). Permits are issued through the Illinois Transportation Automated Permit System (ITAP), which reviews each application for bridge tolerances, construction zones, height clearance, and other route-specific safety factors.
Illinois oversize permit costs typically start around $12–$125 depending on the dimensions, weight, and permit type — single-trip, annual, or superload. Loads crossing the Illinois Tollway system require a separate Tollway permit in addition to your IDOT permit.
Compare Transport LLC handles the full process for you — from permit applications to route planning, escort coordination, and lowboy trucking — so you can move your load on schedule without the back-and-forth.
What counts as an oversize or overweight load in Illinois?
A load is generally classified as oversize if it’s wider than 8 feet 6 inches, or exceeds the state’s legal height or length limits. A load is overweight if the gross vehicle weight exceeds 80,000 pounds, or if individual axle weights exceed Illinois’ posted limits. Loads that significantly exceed these thresholds may be classified as superloads, which require additional engineering review.
Frequently Asked Questions About Illinois Permit Fees
How much does an Illinois oversize permit cost?
Illinois oversize and overweight permit fees generally start around $12 and can run up to $125 or more, depending on your load’s dimensions, weight, axle configuration, and whether you need a single-trip or annual permit. Use the official estimator above for a fee specific to your move.
Is this the same as an Illinois Tollway permit?
No. This estimator covers IDOT permit fees for state highways only. If your route crosses the Illinois Tollway system, you’ll need a separate Tollway overweight/overdimension permit in addition to your IDOT permit.
What is the difference between a single-trip and annual permit?
A single-trip permit covers one specific move along a defined route and is typically valid for five days. An annual permit covers repeated moves of the same configuration over a full year, which is more cost-effective for carriers who haul oversize loads regularly.
