Kansas Oversize / Overweight Permit Requirements
Legal-without-permit dimension limits, escort and pilot car thresholds, height pole rules, daylight-only windows, and holiday restrictions for Kansas oversize moves.
Legal limits without a permit
In Kansas, you can move a load without an OSOW permit up to these dimensions on the Interstate and designated highways. Anything over the limits requires a permit (and may require escorts — see below).
| Dimension | Without a permit | Permit required when |
|---|---|---|
| Width | 8′6″ (federal limit) | Anything wider |
| Height | 13′6″ | Anything taller |
| Combo length | 75′0″ | Anything longer |
| Gross weight | 80,000 lb | Anything heavier |
Escort and pilot car thresholds
When permitted, the following escort or movement-restriction rules apply in Kansas. Thresholds are conservative — your specific permit conditions may impose tighter limits depending on the route.
| Trigger | Dimension | Threshold | Detail |
|---|---|---|---|
| Height pole | Height | 16'0" | Height-pole vehicle required when load exceeds 16' in height. |
| Front pilot car | Width | 14'0" | Front pilot car required for widths over 14' on all highways (K.A.R. 36-1-14). |
| Rear pilot car | Width | 14'0" | Rear pilot car required for widths over 14' on all highways (K.A.R. 36-1-14). |
| Certified escort required | Width | 14'0" | Escort vehicles must be annually registered with KDOT; operators must complete approved KS escort training. |
| Daylight-only movement | Width | 14'0" | Sunrise-to-sunset travel only, 7 days per week, when width exceeds 14'. |
