Do I Need an Over-Dimension Permit?

See Oregon’s Process for Managing Oversize and Overweight Trucks.

Size

  • Width — 8 feet 06 inches.
  • Height — 14 feet 00 inches.

Weight

  • 80,000 pounds gross weight.
  • The axle and group axle weights shown on Weight Table 1.
See our FAQ web page for the length limitations for car haulers in Oregon.
Front Overhang
  • 4 feet 00 inches, measured from the front bumper of the power unit to the front of the load.
Rear Overhang

Solo Vehicle — Overall length not to exceed 40 feet.

  • 3/4 of the wheelbase measured from the center of the last axle to the end of the load.
  • Wheelbase is measured from the center of the first axle to the center of the last axle.
Combination of vehicles — Overall length not to exceed the lengths shown on Group Map 1 and Route Map 7.
  • In most cases, up to 5 feet measured from the end of the trailer to the end of the load.
EXCEPTION: Rear Overhang for Combinations
Legal rear overhang is 1/3 of the wheelbase of the combination measured from the center of the last axle to the end of the load if the following are true:
  • The load length does not exceed 40 feet.
  • The trailer length does not exceed 40 feet.
  • The overall length does not exceed 60 feet.
Wheelbase is measured from the center of the first axle to the center of the last axle of the combination.

Get an Over-Dimension Permit

Permits to exceed the legal dimensions above must be acquired before movement of the oversize load in Oregon.

The single-trip permit can include authorization of county roads. Tax and registration requirements must be met unless exempt by statute or rule.

  • Uphold its commitments with the freight industry.
  • Meet the Agency’s goals for traffic mobility and safety.
State and District Guidelines
These Guidelines were created by CCD and ODOT staff and approved at the Motor Carrier Transportation Advisory Committee allows Over-Dimension Permit staff to issue superload permits by blanket authorization.

State and District Guidelines — Pilot Cars and other Special Requirements

​Please visit our Laws and Rules web page for regulations related to size and weight limits. Find out how to make a civil complaint about a commercial vehicle on this page.

​Carriers with a single trip over-dimension permit for a load over 14 feet 6 inches high must meet one of two requirements:

  1. Use a pilot car escort with an overheight pole in front of the high load throughout the trip.
  2. Have a signed declaration form on file with CCD acknowledging that the carrier is responsible for any injury to persons, damage to property or damage to any highway or highway structure resulting from an overheight movement under the permit.
    • The declaration option is only available to motor carriers that have established accounts with CCD.
    • The declaration form must be signed by the individual owner, a partner, a corporate officer, a partner in a LLP, a manager/member of the LLC or agent.
    • Declaration Form 735-9929 filed for Attachment 75A — Mobile Homes / Modular Units.
    • Declaration Form 735-9930 filed for Attachment 82A — Non-Divisible Loads.
State Administrative Fees
The state administrative fee for a single-trip oversize/overweight permit is $8.00 per truck/trip. These fees are due at the time of application, even if the permit is not used. Some carriers are billed for these fees.
 
The state administrative fee for most annual oversize/overweight permit is $8.00 per truck. These fees are due at the time of application even if the permit is not used. Depending on the type, the fees for some annual permits must be paid for at the time of issuance, while the fees for other types can be billed to the carrier's account.
 
Refer to CCD Administrative Fees for Over-Dimension Permits Chart (form 9973) for more information.
 
County Administrative Fees
The county administrative fee for a single-trip oversize/overweight permit is up to $8.00 per truck/trip, per county. These fees are due at the time of application, even if the permit is not used. Some carriers are billed for these fees.
 
The county administrative fee for an annual oversize/overweight permit is up to $8.00 per truck, per county. These fees are due at the time of application even if the permit is not used. Depending on the type, the fees for some annual permits must be paid for at the time of issuance, while the fees for other types of annual permits can be billed to the carrier's account. Not all counties allow all types of annual permits on their roads.
 
Refer to CCD Administrative Fees for Over-Dimension Permits Chart (form 9973) for more information.
 
Road Use Assessment Fees (RUAF)
A single trip permit must be purchased and RUAF paid for any single, non-divisible load in a heavy haul operation with gross weight in excess of 98,000 pounds and permit weight table 3 (or higher) when traveling in Oregon. This fee takes the place of the weight-mile tax for the loaded portion of the haul. RUAF fee rate tables are available on our Report Your Taxes web page.
 
Oregon Weight-Mile Tax
Use Table A for registered weights of 26,001 to 80,000 pounds. Use Table B forvehicles with special permits at gross weights of 80,001. Weight-Mile Tax rate tables are available on our Report Your Taxes web page.
 
If you have been issued a permit from another road authority (for example, a county or city public works department) to operate on their roads with a single non-divisible load and gross weight in excess of 98,000 pounds, road use assessment fees must be paid.
  • Fill out and submit a County/City RUAF Mileage Report (form 3253). The miles declared on this form are not to be reported again on your Oregon Highway Use Tax Report.
If your permit was issued by CCD and includes county roads or city streets, include all miles traveled on that permitting report.  It is not necessary to fill out form 3253.
 
Refund of Fees
State and County administrative fees are not refundable, even if the permit was not used. Use the Road Use Assessment Fee (RUAF) Refund (form 9977) to request a refund of this fee if:
  • A single-trip permit was issued for the movement of a single non-divisible load.
  • The gross permitted weight was in excess of 98,000 pounds.
  • The permit was paid for with a credit card (or ACH transaction) prior to issuance.
  • The move was not made.
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.
Visit the CCC Center for Business and Industry website.

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. See our State and District Guidelines — Pilot Cars and other Special Requirements for additional information.

  • 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.

 Types of Over-Dimension Loads

​Motor carriers moving loads that exceed 14 feet in height are required to obtain an over-dimension permit and are subject to special requirements and responsibilities. Overheight may not be caused by items loaded in multiples (stacked or overlapped).

The motor carrier and driver:

  • Are responsible and liable for any and all injury to persons or damage to property and all damage to or destruction of any highway or any highway structure resulting from the oversize or overweight movement.
  • Are responsible for determining adequate clearance, both vertical and horizontal, for movement under this permit.
  • Must notify the Over-Dimension Permit Unit within 24 hours of an accident involving striking a structure in the course of a movement.

Motor Carriers moving loads that exceed 8 feet 6 inches in width are required to obtain an Over-Dimension Permit and are subject to special requirements and responsibilities.

Travel restrictions and exceptions are described on Permit Attachment H and apply to all overwidth moves authorized by either an annual or single trip permit that also requires Permit Attachments 70A, 75A or 82A.
 
Overwidth Permit Attachments

Attachment 70A — Continuous Operation Variance Permit, General Provisions.
Attachment 75A — Mobile Home/Modular Unit Provisions.
Attachment 82A — Non-Divisible Loads.
Special Transportation Permit Attachment H — Specific Hauling Hours and Days for Overwidth Movement.

Oregon Administrative Rules
OAR Division 70 — Vehicle Weight and Dimension Limits.
OAR Division 82 — Variance Permits Issued for Non-Divisible Loads.
OAR Division 75 — Movement of Over-Dimension Mobile Homes and Modular Building.

This is a load or combination of load and hauling equipment that exceeds one or more of the following dimensions:
  • Over 16 feet wide on the Interstate.
  • Over 14 feet wide on any state two-lane highway. This does not include mobile/modular units with a 14 foot box or less and up to a 12 inch eave.
  • Over 17 feet high on any highway.
  • Mobile/modular units with a box width over 14 feet wide and/or overall width greater than 15 feet.
  • Overall length greater than 150 feet.
Overweight Superloads
Weight can be a factor in the permitting process depending on the size of the load. Please use the weight tables below to determine your legal and permittable weights.

Load Review
Loads that meet the minimum axle requirements for Permit Weight Table 5 and exceed the allowances on all the weight tables may request that the load be reviewed by a Bridge Engineer.
  • Requests sent to the bridge engineers may take up to 5 business days.
  • Not all of the requests are approved.
  • All requests are route, axle weight and axle spacing specific.
  • Any changes made to an approved engineer review will have to be re-submitted.

​Oregon uses weight tables to determine legal and permittable weights.
Motor carriers can also use our Online Weight Calculator.

Weight Table 1 — Legal Weight, No Permit Required
Use for trucks with legal axle weights hauling divisible loads.
 
​Maximum Weight Allowed​Common Vehicle Types​
​- 600 pounds per inch of tire width.
- 20,000 pounds single axle.
- 34,000 pounds tandem.
- 80,000 pounds gross weight.		​- Solo truck.
- Truck-tractor and semitrailer.
- Truck and trailer.
- Log truck and pole trailer.
 
Weight Table 2 — Extended Weight, Permit Required
Use for trucks with legal axle weights hauling divisible loads.
 
Maximum Weight Allowed​Common Vehicle Types​
​- Between 80,000 pounds and 105,500 pounds.​- Truck-tractor-semitrailer-trailer (aka doubles).
- Triple-trailer combinations.
- Truck-tractor.
- Tri-axle semitrailers.
 
Weight Table 3 — Heavy Haul Weight, Permit Required
Use for trucks with heavy haul / non-legal axle weights hauling a non-divisible load.
 
Maximum Weight Allowed​Common Vehicle Types​
​- Single Trip Permit is based on the number of axles and wheelbase.
- Annual Continuous Operation Permits allows up to 98,000 pounds for non-divisible loads.
- 600 pounds per inch of tire width.
- 21,500 pounds per single axle.
- 43,000 pounds per tandem axle, the weight shown on the over-dimension permit and the sum of the permittable axle, tandem axle, or group axle weight, whichever is less.		​- Truck-tractor-lowbed semitrailer.
- Truck-tractor-semitrailer and booster.
 
Weight Table 4 — Heavy Haul Weight, Permit Required
Use for trucks with heavy haul/non-legal axle weights hauling a non-divisible load. Table 4 allows for more weight using a shorter wheelbase than that authorized by Table 3.
 
Maximum Weight Allowed​Common Vehicle Types​
​- Based on the number of axles and wheelbase.
- 600 pounds per inch of tire width.
- 21,500 pounds per single axle.

- Truck-tractor-lowbed semitrailer.
- Truck-tractor with jeep and semitrailer.
- Truck-tractor with semitrailer and booster.
 
Weight Table 5 — Heavy Haul Weight, Permit Required
Use for specific vehicle configurations only. Weight Table 5 and its formulas for increased weights is more complex than the other tables and requires special analysis by the Over-Dimension Permit Unit.
 
Maximum Weight Allowed​Common Vehicle Types​
​- Up to 48,000 pounds per tandem axle may be allowed if the combination of vehicles has at least 9 axle with a steer axle followed by four consecutive tandem axles which are 8 foot wide (standard).
- Up to 52,800 pounds may be allowed when the combination has 10 foot wide axles with 4 tires per axle.
- Up to 60,000 pounds may be allowed when the combination has 10 foot wide axles with 8 tires per axle.		​- Truck-tractor with jeep, semitrailer and booster.
 
Specific Analysis and Routing
In special circumstances, ODOT's Bridge Unit may authorize additional weight for moving a large non-reducible load. A single trip permit may be issued for combinations of vehicles having minimum equipment consisting of a steering axle followed by four or more consecutive tandem axles, provided the weight does not exceed:
  • 600 pounds per inch of tire width.
  • 24,000 pounds per single axle.
  • 48,000 pounds per tandem axle.
  • The weight shown on the permit.
  • The sum of the permittable axle, tandem axle, or group axle weight, whichever is less.

​A route request is NOT a permit. A separate permit application must be submitted to move an oversize load in Oregon. Requests for changes to the size or weight of your oversize load require a new route request.

Route requests:
If a Route Request is approved, please provide the Route Request Log Number with your permit application.
 
Note: Due to road construction or other restrictions, the route, time frame or permit conditions may be changed by the Department or Road Authority.

A Traffic Control Plan is considered a mobile operation that controls normal traffic from both directions using approved signs and procedures found in the Manual on Uniform Traffic Control Devices and Oregon Temporary Traffic Control Handbook. The operation shall include Oregon certified flaggers in conjunction with the carrier’s pilot cars.
 
The Principal Function of a Traffic Control Plan
  • Provide for reasonably safe and effective movement of road users through or around temporary work zones.
  • Reasonably protect road users in specified areas of a route when less than 12 feet of paved surface is available for oncoming traffic.
  • Reasonably protect road users, workers, traffic incident responders and equipment.
 
Traffic Control Plan Design
Each Traffic Control Plan should be uniquely designed for each load. Some superloads may or may not require a Traffic Control Plan due to the specific orientation of the load, speed of travel, configuration of vehicles and/or a variety of other reasons.
 
Sample Traffic Control Plan — Use for reference only.
 
The motor carrier shall submit the following information in their Traffic Control Plan:
  • A detailed outline of their plan.
  • Key personnel contact information.
  • Necessary traffic control equipment/devices.
  • Planned pullout locations.
  • Details of side roads that will need to be controlled.
  • Safety concerns regarding bridge, double guardrail areas, utility wire, etc.
  • Identify overnight parking areas.
  • Method used to communicate between load, pilots and flaggers.
Basics of a Traffic Control Plan for Moving Over-Dimension Loads
  • Multiple flagger stations will be “leap-frogging” in advance of the oversize load while pilot cars provide advance warning and block approaching traffic from the rear.
  • Locations to stop and clear traffic will be based on the speed of the load and shall occur within a maximum 20 minute time frame.
  • The selected locations for stopping must be adequate for the load to be completely outside of the travel lanes.
  • If locations are not adequate, the carrier or the carrier’s contractor shall be prepared to
    o Release traffic in 2 stages.
    o Pilot the rear traffic around the load if necessary.
  • Traffic is held at every entrance to each section of the road being closed until the load passes.

​Prior to approval of a superload permit, a Route Survey may be required by the regional electrical crews in one or more of Oregon’s five regions.

Our Over-Dimension Permit Analyst will check routes for physical structures and overpasses. This route check DOES NOT include:
  • Signal lines.
  • Utility lines.
  • Traffic signals.
  • Other obstacles the load may encounter.

Route Survey Information

  • A list with locations of low obstacles along a route.
  • Specific locations of obstacles.
  • A plan for navigating around obstacles if possible.
  • The date a route survey was performed.
​Some oversize moves will be monitored by the Oregon Department of Transportation (ODOT) staff as a condition of the permit. Regional and/or district electrical offices will determine whether ODOT staff will need to monitor Overwidth, Overlength or Overheight loads  based on the following criteria.
  • Load geometry.
  • Travel speeds.
  • Impact on traffic.
  • Construction zones.
Costs Associated with Monitored Moves
  • The regional and/or district electrical office(s) will determine whether ODOT staff will bill the motor carrier directly for the cost of monitoring the move and/or any costs of moving signals or adjusting state-maintained utility lines if required.
  • ODOT may bill the motor carrier directly for the cost of having personnel on sight to monitor the move.
​Road construction or other constraints along I-84 may require some oversize loads to detour onto secondary two-lane highways in Central Oregon. ODOT has created the following guidelines so carriers will know what to expect for pilot vehicle and traffic control requirements. Pullout locations are provided to help aid carriers with preparing a traffic control plan if one is required.

Travel Restrictions

Oregon restricts movement of over-dimension loads throughout the year and during six holiday periods. Restrictions depend on the type of combination of truck operations. See your permit and/or attachment for specific details regarding all travel restrictions.
 
​Travel depends upon weather and road conditions at the time of actual movement. Always check for available highway and weather information before beginning a trip. The following resources contain weather-related travel restrictions.
CAUTION: Chain-up locations are not intended to serve as staging areas for over-dimension loads. Parking in chain-up areas is strictly prohibited.

Motor Carrier Responsibility
It is the driver's responsibility to determine if local road conditions are hazardous, unless the Oregon Department of Transportation has closed or posted signs on the highway displaying restrictions due to weather/road conditions in the area.

See the Commerce and Compliance Division’s Policy for Travel During Periods of Inclement Weather.

Motor carriers found to be operating in weather conditions considered hazardous may receive a Civil Complaint and/or Monetary Penalties. In most cases, it is up to the State Police and local law enforcement to address on-highway situations.
Commercial use of Forest Service roads in the Pacific Northwest Region is prohibited without authorization. Contact the Oregon Forest Service for more information about overload and commercial use permits.
​​Appropriate communication and analysis must happen before implementing a proposed weight restriction on the state highway system.

Restriction Letters

The Commerce and Compliance Division regularly sends letters to all holders of annual over-dimension permits notifying them of upcoming road and bridge restrictions that may affect their trucking operations.
Notes:
  • Motor carriers need to provide this information to their drivers to ensure they are aware of the restrictions.
  • Road restriction dates on the recent restriction letters listed below may change or be extended due to weather or other unforeseen delays.
  • Our Restriction List is also available online.
