Oregon-specific requirements
Weight-mile tax replaces the diesel fuel tax
Oregon does not tax diesel through a fuel-use tax for heavy vehicles. Commercial vehicles operating over 26,000 pounds pay Oregon's weight-mile tax on Oregon taxable miles, computed by declared weight (Table A up to 80,000 lb) and by declared weight plus axle count above 80,000 lb (Table B). Vehicles of 26,000 pounds or less instead pay Oregon fuel tax at the pump.
No branded state carrier number - Class 1A Permit plus a CCD account
Unlike Texas (TxDMV Number) or California (CA number), Oregon does not issue a distinct branded intrastate credential number. Intrastate for-hire carriers must hold a Class 1A Permit (form 9745, $300 application fee under ORS 825.402) on file with CCD and operate under a CCD motor carrier account.
Oregon does not collect UCR fees
Although UCR is required for interstate carriers with vehicles over 10,000 pounds, Oregon does not participate in registering or collecting UCR fees. Oregon-based carriers pay UCR directly at the national UCR website.
USDOT number required at 10,000 pounds
Oregon requires a USDOT number for any carrier operating a vehicle with a gross vehicle weight of 10,000 pounds or more (issued free by FMCSA), a lower threshold than the weight-mile tax (over 26,000 lb) and CCD registration (26,001 lb) thresholds.
Flat monthly fee option for logs, wood chips, sand/gravel, and farm haulers
Carriers hauling logs/poles/piling/peeler cores; wood chips/sawdust/bark dust/hog fuel/shavings; dump-body loads of sand/gravel/rock tied to construction; or qualifying intrastate for-hire farm vehicles under 46,000 lb may elect an annual flat fee (paid monthly, per 100 lb of declared weight) instead of the mileage-based weight-mile tax. The election can be changed only once per calendar year.
Road Use Assessment Fees (RUAF) for non-divisible loads over 98,000 pounds
For non-divisible hauls over 98,000 pounds, Oregon replaces the weight-mile tax on the loaded portion with Road Use Assessment Fees based on Equivalent Single Axle Load (ESAL), axle count, and miles. RUAF is calculated and paid to the CCD Over-Dimension Permit Unit at permit issuance.
Distinct plate classes: T, YC, Y1, and YA
Oregon-only vehicles 10,000-26,000 lb get a DMV 'T' plate; Oregon-only commercial vehicles over 26,001 lb get a CCD 'YC' Commercial plate; interstate IRP vehicles 26,000 lb or less get an apportioned tax-exempt 'Y1' (Little Y) plate; and interstate IRP vehicles over 26,001 lb get an apportioned 'YA' plate.
Unprocessed-goods exemption from federal MC authority
A carrier hauling unprocessed commodities may be exempt from the federal MC number requirement. The manual's illustration: hauling raw potatoes is exempt, but hauling french fries (processed potatoes) requires the MC number.
Established-place-of-business requirement to base in Oregon
To base a fleet in Oregon, a carrier needs an established place of business - a physical, street-addressed structure (not a PO box or private mailbox) open during business hours, staffed by a permanent employee, holding the fleet's operational records. Carriers who cannot meet this may register by proving Oregon residency.
Weight-mile tax system being modernized (HB 3991, effective July 1, 2027)
CCD is running modernization projects, including changes under House Bill 3991 taking effect July 1, 2027, that affect the weight-mile tax and reporting systems. Carriers should re-verify enrollment and reporting details against CCD notices as that date approaches.
The permit office and ORION
The Over-Dimension Permit Unit sits inside CCD and works through ORION, the state's routing system. ORION takes the application, builds the route, and carries the operating conditions and any active temporary restrictions for the move. The unit's phone line and the ORION address are sourced fields on this site.
The permit types Oregon issues
A single-trip variance permit covers one load over the legal limits. For repeat work, Oregon offers an annual Continuous Trip Permit that authorizes state highways, and an annual Continuous Operations Variance Permit that can add one or more counties and the City of Portland.
Heavier combinations bring more paperwork. A load running over the base weight ceiling needs an annual extended-weight permit and reports at the heavier weight-mile rate. Pilot car requirements are set by route and district rather than one statewide chart, which our oversize page walks through.

Frequently asked questions
Where do I apply for Oregon truck permits?
- Through ORION, the CCD over-dimension routing system. It takes the application, routes the move, and sets the conditions for oversize and overweight permits. The Over-Dimension Permit Unit issues them.
Does Oregon offer an annual oversize permit?
- Yes, two of them. The Continuous Trip Permit authorizes state highways, and the Continuous Operations Variance Permit can add counties and the City of Portland. Both are annual variance permits for carriers that run oversize often. Our oversize and overweight page carries the sourced details.
What if my load runs over the base weight ceiling?
- You need an annual extended-weight permit, and the move reports at the heavier weight-mile rate. Non-divisible loads past the higher line pay a road use assessment fee instead of the weight-mile tax on the loaded portion, calculated at permit issuance.
