Oregon Apportioned Plates

If you're a commercial carrier operating across multiple states, you'll likely need to register under the International Registration Plan (IRP). This plan allows qualifying vehicles to travel through all participating jurisdictions, including Oregon - using a single apportioned plate. Instead of paying full registration fees in every state you operate, IRP allows those fees to be distributed based on the miles traveled in each state or province, making interstate commerce more efficient and cost-effective.

Who Needs IRP in Oregon?

Not all commercial vehicles are required to register under IRP, but many are. You must register if your vehicle travels across state lines and meets one of the following criteria: it has a gross vehicle weight (GVW) over 26,000 pounds, or it has three or more axles, regardless of weight. This includes most semi-trucks, buses, and commercial fleets that operate interstate. Even if you’re based in Oregon, crossing into another IRP jurisdiction with a qualifying vehicle makes you subject to IRP requirements.

IRP Registration Process

To register for IRP in Oregon, the first step is setting up a Motor Carrier Account with the Oregon Department of Transportation (ODOT). Once that account is in place, you can begin gathering the documents needed to complete your IRP application. These documents include:

A valid USDOT number that is active and in good standing
Proof of an Oregon business location (such as a lease or utility bill)
A title or lease agreement for each vehicle in the fleet
An Oregon Weight-Mile Tax account if the vehicle is over 26,000 lbs
Proof of insurance that meets federal guidelines
A copy of your IRS Form 2290 (Heavy Vehicle Use Tax)

After collecting the documents, you’ll fill out Oregon’s IRP application and list all the jurisdictions where you plan to operate, along with the estimated miles. Your fees will be calculated based on that mileage breakdown. Once approved, you’ll receive apportioned plates and a cab card that must be carried in the vehicle at all times.

Renewal of IRP registration is required annually. Carriers must update their mileage data, ensure all credentials are current, and submit any changes in vehicle or fleet information. Missing your renewal deadline can result in late fees or the suspension of your IRP account.

How to Get a Trip Permit in Oregon

If your vehicle is not registered under IRP but you need to operate temporarily in Oregon or any other IRP jurisdiction - you must obtain a 72-Hour Trip Permit. This permit allows a non-IRP vehicle to travel legally for a limited time without full apportioned registration.

In addition to the trip permit, Oregon requires a Weight-Mile Tax Permit for any commercial vehicle over 26,000 lbs, even for short-term travel. These permits can be acquired through Oregon Trucking Online, authorized third-party permit providers, or directly from ODOT Motor Carrier Services.

Does Oregon Participate in the IFTA?

Yes! Oregon is a full participant in the International Fuel Tax Agreement (IFTA). If your commercial vehicle operates in multiple states and weighs more than 26,000 lbs or has three or more axles, you must obtain an IFTA license and decals.

In Oregon, IFTA credentials are issued through ODOT Motor Carrier Services, not the DMV. Once registered, you’ll be required to renew your IFTA decals annually, separate from your IRP renewal. While Oregon doesn’t charge a state fuel tax on diesel for most commercial carriers operating in-state, IFTA ensures that fuel taxes are paid appropriately when operating out of state.

One important requirement to remember is the quarterly filing of IFTA returns. Even if you didn’t operate your vehicle during a given quarter, you must still file a zero return to stay compliant. And yes - even if you're already registered under IRP, you still need separate IFTA credentials to comply with fuel tax regulations.
