What Is an Oregon Annual Extended Weight Permit?
An Oregon Annual Extended Weight Permit is an annual overweight authorization for qualifying vehicles hauling divisible loads above 80,000 pounds.
Under Oregon's Weight Table 2:
- Maximum gross weight can be up to 105,500 pounds.
- Single-axle weight remains limited to 20,000 pounds.
- Tandem-axle weight remains limited to 34,000 pounds.
- Tire-weight limitations still apply.
- The actual permitted gross weight depends on the vehicle's axle configuration and spacing.
Unlike heavy-haul permits for non-divisible loads, the extended-weight program is designed around vehicles whose individual axle weights remain within legal limits while the overall combination exceeds 80,000 pounds.
Which Vehicles Can Use the Annual Extended Weight Permit?
ODOT currently lists these vehicle types for the Annual Extended Weight permit:
- Truck-tractor and semitrailer
- Truck and trailer
- Doubles
The annual permit allows qualifying combinations to operate under Weight Tables 1 and 2 axle and group-axle weights, with the extended gross-weight allowance reaching up to 105,500 pounds.
This means that simply having an annual permit does not automatically authorize every truck configuration to operate at 105,500 pounds. The vehicle must meet the applicable axle, group, tire, spacing, and route requirements.
When Is the Permit Required?
Oregon's standard legal gross-weight limit is generally 80,000 pounds, subject to the applicable axle and tire restrictions. Vehicles operating above that weight generally need an over-dimension permit.
For qualifying divisible loads above 80,000 pounds, the Annual Extended Weight Permit provides the authorization to operate under Weight Table 2.
For example, a carrier transporting a divisible commodity with a properly configured combination at 90,000, 100,000, or another qualifying weight above 80,000 pounds may need an Extended Weight Permit rather than relying on ordinary legal-weight authority.
The 105,500-Pound Maximum
The frequently cited 105,500-pound maximum is important, but carriers should not interpret it as an automatic operating weight.
Oregon determines allowable weight using its weight tables, axle groups, wheelbase, tire limitations, and other requirements. ODOT specifically states that weight can depend on the vehicle's configuration and that the tire-size and weight charts should be used when determining allowable weight.
Therefore, a carrier should verify the actual permitted weight for the specific truck and trailer combination before loading.
Extended Weight and Weight-Mile Tax
The permit and Oregon's weight-mile tax requirements work together.
Oregon's motor-carrier guidance states that vehicles operating between 80,001 and 105,500 pounds with divisible loads must have a declared tax weight corresponding to the maximum operating weight above 80,000 pounds. The applicable mileage tax is then determined using the appropriate tax table.
Carriers should therefore make sure that:
- The vehicle is properly registered.
- The appropriate weight is declared.
- The Extended Weight Permit is valid.
- Weight-mile tax reporting reflects the applicable declared weight.
- Vehicle configuration and operating conditions are properly accounted for.
ODOT also states that vehicles over 26,000 pounds can be subject to Oregon's weight-mile tax program.
Registration Weight Matters
A permit alone is not a substitute for proper registration and tax declarations.
ODOT states that commercial vehicles over 26,000 pounds must be registered at the heaviest loaded weight at which they will operate in Oregon during the year, with the applicable annual registration fee.
For vehicles operating above 80,000 pounds, carriers should make sure their registration, declared tax weight, and permit authorization are consistent.
Route Restrictions Still Apply
An Annual Extended Weight Permit does not mean that a truck can travel at its permitted weight on every Oregon road.
ODOT specifically warns that overweight loads—even loads qualifying for extended weight with legal single, tandem, and group axle weights—are prohibited from crossing certain weight-restricted bridges. Carriers must review applicable route restrictions and bridge information before operating.
This is particularly important for carriers routinely operating at the upper end of the permitted weight range.

Annual Permit Renewal
ODOT provides annual permit renewal functionality through ORION. Eligible annual permits can appear in the renewal queue shortly before or after expiration.
ODOT notes that automatically renewed permits are essentially an express copy of the original permit with updated effective and expiration dates. If vehicle information, counties, or vehicle type needs to be changed, the permit may need to be manually copied and updated instead.
Carriers should therefore review their permit information before renewal rather than assuming that every vehicle detail will automatically update.
Common Compliance Mistakes
Some of the most important mistakes to avoid include:
- Assuming every vehicle can operate at 105,500 pounds.
- Exceeding the permitted axle or group-axle weight.
- Failing to maintain the proper declared tax weight.
- Operating across a weight-restricted bridge.
- Allowing the annual permit to expire.
- Using the permit for a vehicle or configuration it does not authorize.
- Failing to account for Oregon weight-mile tax requirements.
- Loading a vehicle beyond the manufacturer's tire rating.
- Assuming an Extended Weight Permit authorizes heavy-haul axle weights.
The last point is especially important. Weight Table 2 and Weight Table 3 are different programs. Weight Table 2 concerns extended weight using legal axle weights, while Weight Table 3 is a heavy-haul permit for non-divisible loads and can involve higher axle weights under specific conditions.
Extended Weight vs. Heavy Haul
The distinction can be summarized this way:
| Feature | Extended Weight | Heavy Haul |
|---|---|---|
| Oregon weight table | Table 2 | Table 3 and higher |
| Typical load | Divisible | Non-divisible |
| Gross weight | Up to 105,500 lbs | Varies by permit/configuration |
| Single axle | Up to 20,000 lbs | Can be higher under applicable rules |
| Tandem axle | Up to 34,000 lbs | Can be higher under applicable rules |
| Permit type | Annual available | Annual/single-trip options depending on operation |
| Typical use | Heavy divisible commodities | Specialized heavy loads |
ODOT's current guidance confirms that an Annual Extended Weight permit is available through ORION and allows up to 105,500 pounds under the applicable Weight Table 1 and 2 axle/group limits.
Final Checklist for Oregon Carriers
Before operating with an Annual Extended Weight Permit, trucking companies should verify:
✓ Correct vehicle and trailer configuration
✓ Valid annual Extended Weight Permit
✓ Maximum authorized gross weight
✓ Legal axle and group weights
✓ Tire-weight limitations
✓ Proper Oregon registration weight
✓ Appropriate weight-mile tax declaration
✓ Valid route and bridge restrictions
✓ Permit expiration date
✓ Compliance with all permit conditions
Bottom Line
The Oregon Annual Extended Weight Permit is particularly useful for carriers that regularly haul divisible loads above 80,000 pounds. For qualifying configurations, it can authorize operation up to 105,500 pounds gross weight under Weight Table 2. However, the maximum is subject to axle, tire, spacing, registration, tax, and route requirements.
Carriers should verify their specific vehicle configuration and route requirements before operating at extended weights.
