Oregon oversize permit rules
What Oregon 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 2025-03-13.
Oversize permit
$8
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
Quoted per load
Scales with weight and axle count — there is no single figure.
+ $20 Permigo service fee per permit, state fees at cost.
Legal limits
Exceed any one of these in Oregon and you need a permit for this state.
| Limit | Interstate |
|---|---|
| Width | 8'6" |
| Height | 14'0" |
| Length | 150'0" |
| Gross weight | 80,000 lbs |
| Single axle | 20,000 lbs |

What the permit costs
Oregon 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.
Interstate & multilane
| Width | Requirement |
|---|---|
| Over 14'0" | 1 rear escort14'1"–16'0" wide on Interstate/multilane = ONE pilot, at the REAR (8101 chart + position rule). ≤14' takes NO pilot on Interstate/multilane. Position rule (8101 verbatim): 'When one pilot vehicle is required, it shall travel in front of the oversize unit except when operating on multilane highways it shall be at the rear... When two pilot vehicles are required, one shall be in front and one shall be at the rear... When the number of pilot vehicles specified on the permit is different than the number required above, the permit shall take precedence.' |
| Over 16'0" | 1 front escort + 1 rear escort · superloadOver 16 ft wide on Interstate/multi-lane state highways = SUPERLOAD (ODOT page verbatim). Over 16' the pilot count is 'Specified on Single-Trip Permit' — published district minimums (Pilot Car Guide, May 2026): Interstate/multilane 16'1"–18' (–20' in D2C/D9) = two rear pilots OR one front + one rear (D11/Region 5: two rear); above that typically one front + two rear; Region 5 freeways: to 22' = 1F+2R, 22'–26' freeway-only 0–5-mile early-morning hauls, over 26' NO moves. 16'1"–17" corridor exception (US26/US97/OR126/US20/OR78/US95 segments): blanket authorization if axle width ≤12' and overall ≤150', minimum 2 front + 1 rear. Over 12' wide: certified flaggers (MUTCD) are required at 17 listed structures (Sunset/Elk Creek/Salt Creek/Knowles Creek tunnels, US101 bridges, etc.) — or the Certified Rolling Stop method with THREE certified pilot vehicles (8101; max public delay 20 minutes per Form 734-2360). |
| Height | Requirement |
|---|---|
| Over 14'6" | 1 front escort · height poleOver 14'6" high: ONE front pilot with an over-height pole 'adequate to determine load clearance' — waived only if the permittee has filed the ODOT liability declaration (OAR 734-082-0035(2)(f); 82A: 'When a pilot vehicle is required for height, it shall travel in the front'). Routing keeps a 4-inch vertical clearance buffer (OAR 734-082-0025(3)); any structure strike must be reported to the OD Permit Unit within 24 hours. |
| Over 17'0" | superload permitOver 17 ft high on ANY highway = SUPERLOAD (ODOT Superloads page verbatim) — 'could take up to 10 days to issue.' |
| Length | Requirement |

Permit scheme (OAR 734-082-0030): solo up to the full wheelbase; combinations to ½ the combination wheelbase single-trip; continuous-trip semitrailer combos max 70' load / 80' overall on approved routes. |
