Indiana Oversize / Overweight Permit Requirements
Legal-without-permit dimension limits, escort and pilot car thresholds, height pole rules, daylight-only windows, and holiday restrictions for Indiana oversize moves.
Legal limits without a permit
In Indiana, 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 Indiana. Thresholds are conservative — your specific permit conditions may impose tighter limits depending on the route.
| Trigger | Dimension | Threshold | Detail |
|---|---|---|---|
| Front pilot car | Length | 110'0" | Front pilot car required for combinations over 110' overall length. |
| Rear pilot car | Length | 110'0" | Rear pilot car required for combinations over 110' overall length. |
| Height pole | Height | 14'6" | Height-pole vehicle required when load exceeds 14'6" in height (105 IAC 7-4-7). |
| Front pilot car | Width | 14'4" | Front pilot car required on 2-lane/undivided roads for widths over 14'4" (105 IAC 7-4-7). |
| Daylight-only movement | Width | 14'4" | Travel restricted to 8:30 am–3:30 pm weekdays when width exceeds 14'4". |
| Rear pilot car | Width | 12'4" | Rear pilot car required on divided highways for widths over 12'4" (105 IAC 7-4-7). |
Stop tracking these rules by hand.
