Nevada Oversize / Overweight Permit Requirements
Legal-without-permit dimension limits, escort and pilot car thresholds, height pole rules, daylight-only windows, and holiday restrictions for Nevada oversize moves.
Legal limits without a permit
In Nevada, 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 Nevada. Thresholds are conservative — your specific permit conditions may impose tighter limits depending on the route.
| Trigger | Dimension | Threshold | Detail |
|---|---|---|---|
| Rear pilot car | Length | 110'0" | Rear pilot required when overall length exceeds 110' on any highway. Weekend/holiday max length is 110' (NAC 484D.680). |
| Front pilot car | Front overhang | 25'0" front overhang | Front pilot required when front overhang exceeds 25'. Above this threshold load must have front escort independent of overall width (NAC 484D.640). |
| Rear pilot car | Rear overhang | 25'0" rear overhang | Rear pilot required when rear overhang exceeds 25'. Independent of overall width or length triggers (NAC 484D.640). |
| Height pole | Height | 15'6" | Front pilot car must carry a clearance-pole/height measuring device for loads over 15'6" tall (NAC 484D.675). |
| Front pilot car | Width | 14'0" | Front pilot required on 2/3-lane roads for widths 12'1"–14'. On 4+-lane highways, front pilot required only when width exceeds 16' (NAC 484D.640). |
| Rear pilot car | Width | 14'0" | Rear pilot required on 4+-lane roads for widths over 14'. On 2/3-lane roads, rear pilot added when width exceeds 14'. Lead+chase required above 16' on all roads (NAC 484D.640). |
| Daylight-only movement | Width | 14'0" | Weekend/holiday travel restricted to widths 14' or less. Weekday max is 17'. Loads over 14'W / 15'H / 110'L are prohibited on Sat/Sun and 12 Nevada holidays (NAC 484D.680). |
| Weekend / holiday restriction | Width | 14'0" | 12 Nevada holidays including Nevada Day (last Friday Oct), Family Day (4th Friday Nov), Juneteenth, MLK, Presidents' Day, Veterans' Day, plus 6 federal holidays (NRS 484D.715). |
