Over-Dimension Operations in Oregon

Get an Over-Dimension Permit

Permits to exceed the legal vehicle dimensions must be acquired before movement of the oversize load in Oregon. The single-trip and annual permits can include authorization of county roads and/or city of Portland streets. Tax and registration requirements must be met unless exempt by statute or rule.

Oregon Routing Information Online (ORION)

Over-dimension permits can be ordered through ORION, our web-based self-service permitting system. ORION provides access to both single trip permits and annual permits.

For more information about the new system, training resources and instructions on how to establish your account, please visit the ORION Project page.

Permit Attachments

The following attachments and route maps provide the motor carrier with information and provisions of the permit.

Certified Flaggers

Motor Carrier Requirements

There are many locations and situations where motor carriers are requirement by permit to use certified flaggers to stop traffic so a truck with an overwidth and/or overheight load can safely pass.

Whenever certified flaggers are a requirement of a permit, the Certified Flagger Attachment must accompany the permit.

Certified Flagger Requirements

To work as a flagger on Oregon State highways you must have training and possess one of the following:
  • A valid Oregon Certified Flagger card.
  • A valid Certified Flagger card from the state transportation departments of Montana, Washington or Idaho.
    o This is available through an interstate reciprocity agreement.
    o The card is valid for three years from the date issued.

Flagger Certification Training

ODOT has authorized the Chemeketa Community College Center for Business and Industry as the exclusive administrator of flagger curriculum, materials and flagger trainer and flagger certification cards.

Chemeketa Community College:
  • Provides a four-hour flagger training class.
  • Maintains a list of certified private flagging trainers.
Contact Information
Call Dawn Pahl at 503-399-5181.

Pilot Vehicles

For each highway in the state, pilot vehicle(s) may be required based on the vehicle's or load's width, height, overall length and overhang. Please use the following forms.

  • Route Map 2 shows these requirements for travel on multi-lane highways as well as two-lane highways shown as Green, Purple and Red routes.
  • To perform a rolling stop, pilot vehicles must be certified in the rolling stop method.
  • The rolling stop method uses three pilot vehicles to allow the motor carrier to straddle the centerline.
