1. Set Up Your Oregon Motor Carrier Account Early
Before operating in the state, most carriers must register for an Oregon Motor Carrier Account with the Oregon Department of Transportation (ODOT).
This account is required for:
-
Weight-Mile Tax reporting
-
Trip permits
-
Overweight/oversize permits
-
Temporary Enrollment Documents (TED)
Setting it up early ensures you avoid operational delays at ports of entry.
2. Understand the Oregon Weight-Mile Tax
Oregon is one of the few states that does not participate in IFTA for fuel tax for heavy vehicles.
Instead, vehicles over 26,000 lbs must pay the Weight-Mile Tax.
Key requirements:
-
Track miles operated only inside Oregon
-
File weight-mile tax reports monthly or quarterly
-
Keep driver logs, fuel receipts, and mileage records organized
Failure to file on time can lead to penalties and suspension of your account.
3. Use a Temporary Enrollment Document (TED) If Needed
If you don’t yet have a permanent account number, you can operate with a Temporary Enrollment Document (TED).
A TED allows immediate entry into Oregon while your permanent credentials are processing.
This is especially useful for:
-
New carriers
-
One-time or urgent trips
-
Out-of-state operators not already registered
4. Know When You Need Trip Permits
If your truck doesn’t have an Oregon account or is not weight-mile-tax eligible, you may need:
-
Oregon Trip Permit (for occasional operation)
-
Oregon Fuel Permit (if you are not in IFTA)
Trip permits must be obtained before entering the state.
5. Follow Oversize/Overweight (OSOW) Rules
Oregon enforces strict OSOW rules that differ from many states.
Important points:
-
Maximum height: 14 ft
-
Maximum width: 8 ft 6 in
-
Maximum length varies by vehicle and combination
-
Overweight loads require axle spacing and weight compliance
-
Some loads need pilot cars depending on size and route
Always verify:
✔ Current OSOW permit requirements
✔ Bridge restrictions
✔ Travel-time curfews
✔ Holiday/weekend restrictions
6. Use the Oregon Trucking Online System
Oregon Trucking Online makes compliance easier by allowing you to:
-
Order permits
-
File weight-mile taxes
-
Update fleet information
-
Pay account balances
-
Check routing and restrictions
New carriers should register for online access immediately after receiving their account number.
7. Keep Documentation Ready for Ports of Entry
Oregon has several active Ports of Entry, and you should be prepared to show:
-
Bill of lading
-
USDOT/MC authority documents
-
Oregon account or permit
-
IFTA credentials (if applicable)
-
Safety and equipment inspection records
Organized paperwork prevents delays during inspections.
8. Maintain Accurate Mileage and Trip Records
Because Oregon relies heavily on weight-mile reporting, accurate trip data is essential.
Your records should include:
-
Date and miles traveled in Oregon
-
Route used
-
Vehicle unit number
-
Weight classification
-
Driver name
Electronic logging devices (ELDs) make this easier and more accurate.
9. Stay Aware of Chain-Up and Winter Travel Laws
Oregon enforces chain requirements in mountain passes and winter zones.
Carriers must:
-
Carry chains when required
-
Follow posted chain-up instructions
-
Avoid restricted routes during severe weather
Violations can lead to large fines or road closures.
10. Keep Your Account in Good Standing
Your Oregon Motor Carrier Account can be suspended for:
-
Late weight-mile filings
-
Unpaid taxes or penalties
-
Incorrect mileage reporting
-
Permit violations
Always file on time, pay promptly, and correct any discrepancies quickly.
Bottom Line
New carriers operating in Oregon must understand that the state has its own unique compliance system, separate from many national programs. By staying proactive with permits, weight-mile taxes, recordkeeping, and safety rules, you can operate smoothly and avoid costly compliance issues.
