Entry Policy

Policy for Over-Dimension Loads Entering Oregon

In addition to other requirements for operating in Oregon, such as registration requirements, motor carriers transporting oversize or overweight loads that originate in Oregon must obtain a variance permit and the driver must possess that permit prior to transport. See a handout about Oregon´s Entry and Enforcement Policy.

Similarly, carriers transporting oversize or overweight loads and entering Oregon from another state must obtain a variance permit and the driver must possess that permit prior to entering the State, except as provided in (1), (2), and (3) below:

EXCEPT: Vehicles entering Oregon on US97 at the OR/CA border may not exceed 21,500 pounds on a single axle or 43,000 pounds on a tandem axle, or a total gross weight of 98,000 pounds or weight in Weight Table 3.
Divisible Load: Legal axle and groups of axle weights, and the total gross vehicle weight must not exceed 105,500 pounds or the weights in Weight Table 1 and Weight Table 2.

PILOT VEHICLES: Unless operating with a front and rear pilot vehicle, warning lights as described in OAR 734-082-0036 are required when width exceeds 10 feet on two-lane highways or 12 feet on four-lane highways. Loads exceeding 12 feet on two-lane highways must use a front pilot vehicle.

To obtain a variance permit:
See Permit Service & Agents

This policy does not authorize vehicles to operate in or enter Oregon prior to obtaining tax and registration credentials. Tax and registration service is available from a Salem Service Center at 503-378-6699, with staff on duty 24 hours a day, 7 days a week, although limited registration services are available after hours, Monday through Friday, between 5 p.m. and 8 a.m., on weekends, and holidays. The Service Center is closed on New Years Day, Thanksgiving Day, and Christmas Day.

This policy does not authorize a vehicle to exceed the size or weight limits posted on a highway. Due to road construction or other circumstances, highways may be temporarily closed or restricted to lesser dimensions or weights.

Weight Tables
pic of weight table

Table 1 - Legal Weight - No Permit Required
Maximum weight allowed - 600 lbs. per inch of tire width, 20,000 lbs. single axle, 34,000 lbs. tandem, 80,000 lbs. gross weight. Common vehicle types: solo truck, truck-tractor and semitrailer, truck and trailer, log truck and pole trailer.

Table 2 - Extended Weight - Permit Required
Permits based on Table 2 allow between 80,000 lbs. and 105,500 lbs. maximum. Common vehicle types: truck-tractor-semitrailer-trailer (aka doubles), triple-trailer combinations, truck-tractor and tri-axle semitrailers.

Table 3 - Heavy Haul Weight - Permit Required
Annual, continuous operation permits based on Table 3 allow up to 98,000 lbs. for non-divisible loads. Maximum weight for single-trip permits is based on the number of axles and wheelbase. Other maximums: 600 lbs. per inch of tire width, 21,500 lbs. per single axle, 43,000 lbs. 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. Common vehicle types: truck-tractor-lowbed semitrailer, truck-tractor-semitrailer and booster.

Table 4 - Heavy Haul Weight - Permit Required
Maximum weight for Table 4 permits is based on the number of axles and wheelbase. Table 4 allows for more weight using a shorter wheelbase than that authorized by Table 3. Other maximums: 600 lbs. per inch of tire width, 21,500 lbs. per single axle, 43,000 lbs. 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. Common vehicle types: self-propelled crane, truck-tractor-lowbed semitrailer, truck-tractor with jeep & semitrailer, truck-tractor with semitrailer & booster.

Table 5 - Heavy Haul Weight - Permit Required
Weight Table 5 is for certain specific vehicle configurations only. It provides for up to 48,000 lbs. per tandem axle if the combination of vehicles has at least 9 axle, with a steer axle followed by four consecutive tandem axles which are 8' wide (standard). Ten percent more weight may be allowed when the combination has 10' wide axles with 4 tires per axle. Instead of 48,000 lbs. per tandem, this allows up to 52,800 lbs. Or additional weight -- 25% more -- may be allowed when the combination has 10' wide axles with 8 tires per axle. Instead of 48,000 lbs. per tandem, this allows up to 60,000 lbs.

Use of 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. Subject to special routing and analysis, single-trip permits 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 lbs. per inch of tire width, 24,000 lbs. per single axle, 48,000 lbs. per tandem axle, the weight shown on the permit and the sum of the permittable axle, tandem axle, or group axle weight, whichever is less. Also, in special circumstances ODOT's Bridge Unit may authorize additional weight for moving a large, non-reducible load. Common vehicle type: truck-tractor with jeep & semitrailer & booster.

Background regarding over-dimension variance permits
The Motor Carrier Transportation Division (MCTD) issues single-trip and annual variance permits for overweight, over-height, over-width, over-length, and other unusual truck loads. The permits include routing plans, road restriction information, and other permit conditions. Permits and routing cover state and federal highways. They can also cover county roads, with county approval, but most Oregon counties issue their own permits. MCTD issues nearly 100,000 complex single-trip permits each year and manages the work of private parties that process requests for about 50,000 continuous, annual variance permits each year (see Permit Agents). Oregon participates in the Western Regional Permit Agreement that makes it possible for truckers to obtain permits for travel in nine other states.

Truckers will need an over-dimension variance permit whenever their vehicle combination exceeds maximum size and/or weight limits. A permit is also needed to haul any single, non-divisible load for which any one of the following conditions apply:
• Width of the load or hauling equipment exceeds 8 feet, 6 inches
• Height of vehicle or vehicle combination and load exceeds 14 feet
• Any single axle weight exceeds 20,000 pounds
• Any tandem axle weight exceeds 34,000 pounds
• Gross combination weight exceeds 80,000 pounds
• Front overhang exceeds 4 feet beyond the front bumper of the vehicle
• Load greater than 40 feet, exceeding 5 feet beyond the end of the semi-trailer, or load less than or equal to 40 feet, exceeding 1/3 of the wheelbase of the combination, whichever is less
• Gross weight of a group of axles exceeds those set forth in the legal weight table shown on the reverse of Group Map 1
• Vehicle combination length exceeds those authorized on the reverse of Group Map 1

Super Loads

Any load exceeding the following dimensions is considered a Super Load:
  • Over 16' wide on the Interstate
  • Over 14' wide on any state two-lane highway
    (This does not include mobiles with a 14' box or less and up to a 12" eave.)
  • Over 17' high on any highway
  • Mobile with over a 14' box or more than 15' total width
  • Overall length over 150'

A super load or route request must be submitted on the Route Request and Permit Application form. It could take up to 10 days to issue. Fax completed applications to 503-378-2873, and make sure to put in a contact name and phone number.

Road Use Assessment Fees
pic of fee table

Fees for single-trip, non-divisible loads 98,001- to 500,000 lbs. maximum gross weight

The road use assessment fee takes the place of the weight-mile tax for the loaded portion of non-divisible hauls. The fee is 5.7 cents per equivalent single-axle load (ESAL) mile traveled. These fees are expressed in terms of permit gross weight and number of axles. As with the Table "B"  weight-mile tax rates, carriers are assessed a lower per-mile charge the greater the number of axles used at any given gross weight.

Pilot Car Requirements
map of Oregon Districts

Guide to Pilot Vehicle Requirements  on Oregon highways that have truck width and length limits.

For each section of the state, in Districts 1-14 and in Region 5, pilot vehicle requirements are outlined for travel on multi-lane highways as well as the two-lane highways shown as Green, Purple, and Red routes on Oregon Route Map 2. The Guide also lists other specific limitations on movements within each District and Region 5. This was eveloped to establish conformity between Districts, particularly for loads over 14' wide on two-lane, and 16' wide on multilane.

Hauling Hours and Days for Overwidth Moves

Truck movements in Oregon are restricted and require an over-dimension variance permit whenever the width of a load or the hauling equipment exceeds 8 feet, 6 inches.

In the past the movement of wide loads, whether it be manufactured homes, modular units, towed units, or wide non-divisible loads, was restricted statewide before, during, and after every major holiday. But in 2006 an Oregon DOT staff study of average daily traffic counts found that at certain times on the Interstates and highways like US97 restrictions are not necessary for the safety of the traveling public. In fact, the blanket restriction typically led to a spike in the number of overwidth loads moving right after the holiday period, which actually caused increased congestion and safety concerns.

Current guidelines now seek to provide for a more uniform traffic flow of overwidth loads during holiday periods. The Motor Carrier Division has a two-page Permit Attachment H  that describes the hauling hours and days for overwidth moves. The attachment describes restrictions on loads up to 10' wide, 10' 1" to 12' wide, 12' 1" to 14' wide, and over 14' wide. It shows what's allowed during hours of darkness, during Summer daylight hours from Memorial Day to Labor Day, during certain peak commuter hours in Portland, Salem, Eugene, Grants Pass, and Medford, and during observed holiday periods. 

Permit Attachment H shows, for example, that when the overall width of the load does not exceed 14 feet, it's allowed to be moved on Thanksgiving Day, Friday, and Saturday on Interstate highways, US97, and any route east of US97 shown in black on Route Map 6, for manufactured homes and modular units, or Route Map 9, for over-size / overweight vehicles and loads. When the overall width of the load does not exceed 14 feet, it's allowed to be moved on those same routes on the other major holidays -- New Year's Day, Memorial Day, Independence Day, Labor Day, Christmas Day -- on Friday and Saturday when the holiday or observed holiday falls on Friday, and on Saturday and Sunday when the holiday or observed holiday falls on Monday.

Special Transportation Permit Attachment H applies to all overwidth moves authorized by either Annual or Single Trip permits that also require attachments 70A, 75A, or 82A.

Mobility Operations Manual

Oregon is experiencing a construction boom. In coming years every corner of the state will be impacted as an unprecedented amount of funding is directed to road construction, maintenance, and preservation, as well as the repair or replacement of hundreds of bridges. State legislators have made more than $3 billion available under what’s called the Oregon Transportation Investment Act (OTIA).  This is in addition to the federal and state funds committed to the Statewide Transportation Improvement Program, which represents over $1.3 billion in projects and programs for 2004-2007 and over $1.2 billion for 2006-2009.

The Oregon DOT has developed a Highway Mobility Operations Manual  as a guide to how Oregon will tackle an unprecedented amount of construction activity and still keep traffic and freight moving. It’s a comprehensive outline of the approach that the Oregon DOT and its construction partners will take when planning and executing all road and bridge projects. It sets project standards and minimum requirements regarding communication and coordination, vertical and horizontal clearance, bridge weight restrictions, delays, detours, staging, and design.
