Oregon has unique trucking regulations compared to many other states—especially around weight-mile taxes, permits, and routing. New carriers who understand these rules early can avoid costly fines and delays.
Oregon Permits for New Carriers

1. Set Up Oregon Weight-Mile Tax (WMT) Correctly

Oregon does not use IFTA alone for heavy vehicles.

  • Vehicles 26,001 lbs+ must register for Oregon Weight-Mile Tax

  • You’ll need:

    • A CCD (Commerce and Compliance Division) account

    • Quarterly WMT reporting

  • Failure to file = heavy penalties and out-of-service risk


2. Use Oregon Trucking Online

New carriers should:


3. Know Oregon’s Strict Weight Enforcement

Oregon enforces axle and bridge weights aggressively.

  • Even legal gross weight can be illegal if axle spacing is wrong

  • Bridge formulas are strictly applied

  • Weigh stations are active statewide

Tip: Always verify axle spacing before entering Oregon.


4. Plan Routes Carefully (Especially for Height)

Oregon has:

  • Mountain passes

  • Coastal roads

  • Forest highways

  • Older bridges with lower clearances

For tall loads:

  • Double-check height on permits

  • Avoid “assumed clearance”

  • Follow permit routing exactly


5. Understand Oversize Travel Restrictions

Oversize loads may be restricted by:

  • Time of day

  • Weekends and holidays

  • Weather (snow, wind, fog)

Common rules:

  • Daylight-only travel for wide loads

  • Reduced speed limits

  • No travel during major holidays without approval


6. Pilot Car Rules Are Strict

Oregon has specific escort requirements:

  • Width over 12 ft → pilot car required

  • Additional escorts for extreme width/length

  • Certified pilot car operators only

Incorrect escort usage is a top citation.


7. Weather Can Shut You Down Fast

Oregon weather changes quickly.

Watch for:

  • Snow chains on mountain routes

  • High wind advisories in eastern Oregon

  • Fog and rain on coastal highways

Permits can be temporarily suspended due to weather.


8. Temporary Trip & Fuel Permits

If you’re not registered:

  • IRP → need Oregon Trip Permit

  • IFTA → need Oregon Fuel Permit

These are enforced at weigh stations.


9. Keep Digital & Paper Records in the Truck

Drivers should carry:

  • OS/OW permits

  • Trip and fuel permits

  • WMT credentials

  • Insurance

  • Registration

Officers often check documents roadside.


10. Watch Logging & Forest Zones

Logging trucks and forest highways have:

  • Special rules

  • Weight tolerances

  • Seasonal restrictions

Do not assume standard highway rules apply.


11. Expect Frequent Inspections

Oregon is known for:

  • Active weigh stations

  • Mobile enforcement units

  • Detailed inspections

Good compliance history reduces inspection time.


12. Common Mistakes New Carriers Make

  • Ignoring Weight-Mile Tax

  • Running permits with wrong axle counts

  • Missing pilot car certification

  • Deviating from permitted routes

  • Underestimating weather restrictions

Avoiding these saves time and thousands in fines.
