Permits
Anything over legal size needs an ODOT Commerce and Compliance Division (CCD) permit before the load moves. ODOT issues single-trip and annual over-dimension permits. They can include county roads, and Portland city streets on annual permits only. Tax and registration requirements also apply.

Pilot cars
Oregon sets pilot vehicle requirements by highway, using Route Map 2 (multi-lane, plus Green, Purple and Red two-lane routes) and permit attachments 75A/82A. Highlights from ODOT's pilot car guide:
| Situation | Requirement |
|---|---|
| Purple two-lane routes | Allowed up to 14 ft wide under route rules |
| Red two-lane routes | Allowed up to 12 ft wide under route rules |
| Over 14 ft (Purple) / over 12 ft (Red) | Case-by-case district approval. Minimum of 1 front and 1 rear pilot. Day and time may be restricted. |
| Over 14 ft 6 in high | Front pilot with height pole, unless a signed liability/height declaration is on file |
| Units ≤ 12 ft wide on Group 1 highways | Exempt from a rear pilot if they meet the warning-light rules |
Some corridors have special rules, such as the Astoria-Megler Bridge (over 12 ft needs district approval) and parts of US-101 and US-26 on the coast.
