Kansas oversize permit rules
What Kansas charges for a single-trip OS/OW permit, the limits that trigger one, and the escort thresholds — read from the state’s own publication. This rule has been in effect since 2020-01-01; we last read the source on 2026-07-10.
Oversize permit
$40
One price for a single-trip permit, whatever the dimensions. A 9-foot-wide load and a 16-foot-wide load pay the same.
Overweight permit
From $40
Scales with weight — there is no single figure.
A load that is both oversize and overweight pays this fee only, not both.
+ $20 Permigo service fee per permit, state fees at cost.

What the permit costs
Kansas prices a single-trip permit as flat rate. One price for a single-trip permit, whatever the dimensions. A 9-foot-wide load and a 16-foot-wide load pay the same.
Escort requirements
Thresholds by road class. Where two classes differ, the road you are actually on governs.
4+ lanes

|---|---|
| Over 14'0" | Marking requiredOver 14' wide on highways of four lanes or MORE: no escort required for standard loads (K.A.R. 36-1-36 verbatim: 'All other types of loads shall not require escorting.') — escorts on 4+ lane roads apply only to superloads and large structures (rear escort).Kansas Turnpike (tolled I-35/I-335/I-470/I-70): the KTA runs its OWN stricter regime — secondary sources: 12'6"–14' wide daytime-only; >14' wide = front+rear escorts, 8:30am–4:30pm Mon–Thu only; ~16' practical width max; >14' high needs Turnpike KHP approval.
