Oregon Annual Permits for Oversize Loads

Dec. 8, 2025, 7:10 p.m.
Oregon offers several types of annual oversize permits that allow commercial carriers to operate vehicles or loads exceeding standard legal dimensions without needing to purchase single-trip permits each time. These annual permits are designed to simplify operations for companies that frequently move oversize equipment, machinery, or specialized loads within the state.

1. What an Oregon Annual Oversize Permit Allows

An annual oversize permit typically authorizes travel for loads that exceed legal limits in width, height, or length, but only up to specific statewide maximums. In general, annual oversize permits allow:

  • Extra width (commonly up to 10 feet on most configurations)

  • Extended length for certain vehicle combinations

  • Some height variance depending on the permit type

  • Repeating routes without reapplying

Annual permits streamline operations but do not replace the need for escort vehicles or special route approvals if your load exceeds allowed dimensions.

2. Eligibility for Annual OS Permits

To qualify, carriers must:

  • Hold valid Oregon operating credentials (Unified Carrier Registration, USDOT, etc.)

  • Have vehicles registered or legally allowed to travel in Oregon

  • Maintain compliance with weight limits—even with oversized dimensions

  • Agree to follow state routing rules and any restrictions listed on the permit

3. Common Types of Oregon Annual Oversize Permits

Oregon provides several varieties of annual oversize permits, including:

A. Annual Overwidth Permit

  • Typically allows widths up to 10 feet on most highways

  • Applies to non-divisible loads

  • Includes route restrictions and safety requirements

B. Annual Overlength Permit

  • Covers combinations exceeding standard length limits

  • Often applies to truck–trailer combinations or specialized equipment haulers

C. Annual Mobile Home/Modular Unit Permit

  • Issued for transporters moving manufactured homes

  • Includes strict routing, daylight travel windows, and escort rules

D. Annual Permits for Specific Industries

Examples:

  • Forest products

  • Agricultural equipment

  • Construction machinery

These often have customized allowances and route limitations.

4. Travel Restrictions for Annual OS Permits

Even with the permit, Oregon requires carriers to follow strict travel rules:

  • Daylight-only travel for certain widths or lengths

  • Holiday and weekend restrictions

  • Curfew zones in major metro areas

  • Prohibited routes for larger configurations

  • Weather-related restrictions (e.g., high winds, low visibility)

If your load exceeds what the annual permit covers, a single-trip permit is required.

5. Escort (Pilot Car) Requirements

Escort vehicles may be required based on:

  • Actual width

  • Configuration and weight

  • Specific road segments

  • Bridge or tunnel constraints

Escort requirements remain in effect even if an annual permit is held.

6. Cost and Validity

  • Oregon annual oversize permits are generally valid for 12 months.

  • Fees vary by permit type and vehicle category.

  • Permits must be carried in the vehicle or accessible electronically.

7. How to Obtain an Annual OS Permit

Carriers can apply through:

  • Oregon Trucking Online (OTO) – fastest method

  • Oregon Motor Carrier Transportation Division (MCTD) by phone or email

  • Authorized permitting services

The application will require vehicle details, dimensions, and anticipated operating routes.

8. Reasons to Use an Annual Permit

Annual oversize permits are a great fit for carriers who:

  • Move similar-sized equipment frequently

  • Operate consistently within Oregon

  • Want to reduce administrative time and cost

  • Need flexibility for repeated routes or daily operations

They are especially useful in construction, agriculture, manufacturing, logging, and machinery transport.
