Utah Oversize / Overweight Permit Requirements
Legal-without-permit dimension limits, escort and pilot car thresholds, height pole rules, daylight-only windows, and holiday restrictions for Utah oversize moves.
Legal limits without a permit
In Utah, 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 Utah. Thresholds are conservative — your specific permit conditions may impose tighter limits depending on the route.
| Trigger | Dimension | Threshold | Detail |
|---|---|---|---|
| Police escort | Length | 175'0" | One state police escort required for lengths over 175'. Two police escorts required for lengths over 200' (R909-2-24). |
| Rear pilot car | Length | 120'0" | Two pilots (lead+chase) required for lengths over 120' on secondary roads. Same threshold applies on divided/Interstate for non-divisible loads (R909-2-24). |
| Front pilot car | Length | 105'0" | One pilot required on secondary roads for lengths over 105'. On divided/Interstate, one pilot required at lengths over 120' (R909-2-24). |
| Front pilot car | Front overhang | 20'0" front overhang | Front pilot required when front overhang exceeds 20'. Position matches overhang side (R909-2-24). |
| Rear pilot car | Rear overhang | 20'0" rear overhang | Rear pilot required when rear overhang exceeds 20'. Independent of overall length triggers (R909-2-24). |
| Police escort | Height | 17'6" | State police escort required for loads over 17'6" tall on secondary roads, and on all roads per permit conditions (R909-2-24). |
| Police escort | Width | 17'0" | State police escort required on secondary roads for widths over 17'. Required on all highways for widths over 20'. Combined width+height extremes may also trigger (R909-2-24). |
| Height pole | Height | 16'0" | Two pilots required for heights over 16' on all highways. Lead pilot must carry height-clearance pole (R909-2-24). |
| Rear pilot car | Width | 16'0" | Two pilots (lead+chase) required on divided highways when width exceeds 16'. On secondary roads, lead+chase required at widths over 14' (R909-2-24). |
| Front pilot car | Width | 14'0" | One pilot required on divided/Interstate for widths over 14'. On secondary roads, one pilot required at widths over 12'. Lead position typical (R909-2-24). |
| Certified escort required | Width | 12'0" | UDOT certification required for all escort vehicle operators. Reciprocal with AZ, CO, FL, GA, MN, NC, OK, VA, WA (R909-2-15). |
| Daylight-only movement | Width | 12'0" | Loads over 14'6"H, 12'W, 105'L, or 10' front/rear overhang restricted to daylight hours per R909-2-15. Nighttime travel requires 2 pilots on Interstate for widths over 12'. |
| Weekend / holiday restriction | Width | 10'0" | Loads over 10' wide prohibited on Christmas, New Year's Day, Memorial Day, Independence Day, Labor Day, Thanksgiving. Holiday window begins noon of preceding day (R909-2-15). |
