How to Stay Compliant with Oregon Trucking Laws

 

1. Register Properly Before Entering Oregon

Most commercial carriers must complete Oregon’s registration requirements before operating in the state, including:

Operating without these can result in immediate penalties at the first weigh station.


2. Understand Weight and Size Limits

Oregon enforces strict:

  • Gross vehicle weight limits

  • Axle weight restrictions

  • Length, width, and height rules

If your vehicle exceeds legal limits, you must obtain an oversize or overweight permit in advance.


3. Keep Permits in the Truck

Drivers should always have:

  • Trip permits or annual permits

  • Oversize/overweight permits (if applicable)

  • Fuel tax credentials

  • Registration and insurance documents

Inspectors expect these documents to be readily available.


4. Stop at All Weigh Stations

Oregon requires most commercial vehicles to stop at:

  • Ports of entry

  • Weigh stations

  • Mobile enforcement sites

Bypassing a scale is a serious violation and often results in higher fines than paperwork errors.


5. Maintain Accurate Logs and Records

Ensure:

  • ELDs are functioning properly

  • Hours-of-service logs are current

  • Vehicle inspection reports are completed

  • Weight-mile records are accurate

Oregon inspectors frequently audit these during roadside checks.


6. Train Drivers on Oregon-Specific Rules

Your drivers should know:

  • When to stop at scales

  • How to present permits

  • Oversize travel time restrictions

  • Escort vehicle requirements

Well-trained drivers prevent costly mistakes.


7. Renew and Update on Time

Track expiration dates for:

  • Weight-mile accounts

  • Trip permits

  • Oversize/annual permits

  • Insurance filings

Late renewals can make your truck instantly non-compliant.
