1. Entering Incorrect Vehicle or VIN Information
One of the most frequent errors is providing the wrong vehicle identification number (VIN), plate number, or unit number.
-
Why it matters: Oregon permits are vehicle-specific. Incorrect VINs invalidate the permit.
-
How to avoid it: Double-check the vehicle’s registration and input information exactly as listed on your MCTD or IRP records.
2. Miscalculating Axle Weights or Spacing
Oregon has strict axle weight and bridge spacing rules. Even a small miscalculation can cause a violation.
-
Tip: Use ODOT’s axle spacing worksheet or a weight calculator before submitting.
-
Pro Tip: If you’re unsure, contact the ODOT Over-Dimension Permit Unit for a pre-check.
3. Requesting the Wrong Type of Permit
Many carriers confuse oversize, overweight, trip, or fuel permits.
-
Oversize/Overweight Permits: For loads exceeding legal size or weight limits.
-
Trip Permits: For carriers operating temporarily in Oregon without IRP registration.
-
Fuel Permits: For carriers without IFTA credentials.
-
How to avoid it: Identify the exact purpose of your trip and confirm with ODOT’s online permit system before payment.
4. Ignoring Route Restrictions
Oregon’s routes have variable limits depending on road class, bridge strength, and weather.
-
Mistake: Choosing a route that doesn’t support your load’s dimensions or weight.
-
Solution: Always check ODOT’s Route Map & Restrictions tool and ensure your selected route is pre-approved for your configuration.
5. Missing Escort or Pilot Car Requirements
Oregon often requires escort vehicles for oversize loads beyond certain dimensions.
-
Example: Loads over 12 ft wide or 14 ft high may need one or two escorts depending on the route.
-
Avoid this mistake: Review Oregon’s Pilot Vehicle and Escort Requirements Manual before traveling.
6. Not Including Load-Specific Details
Incomplete information—such as load type, trailer length, or number of axles—can delay approval.
-
Example: If you’re hauling a modular home or heavy equipment, specify exactly what it is.
-
Tip: The more precise you are, the faster ODOT can approve your permit.
7. Waiting Until the Last Minute
Some permit types (especially superloads or special routing) require manual review.
-
Problem: Applying the same day you plan to move may result in long waits.
-
Solution: Apply at least 24–48 hours in advance for routine loads and up to 5 business days for superloads.
8. Using the Wrong Account or Login
ODOT requires an active Motor Carrier Account to apply for most permits.
-
Mistake: Carriers sometimes use outdated or inactive accounts.
-
Fix: Ensure your account is up to date and linked to your USDOT number. Verify via www.oregontruckingonline.org
9. Forgetting to Carry the Permit in the Vehicle
Even after approval, many drivers forget to print or store a digital copy of their permit.
-
Why it matters: Oregon law requires the permit to be carried and shown upon request.
-
Fix: Keep a printed copy in your cab or a digital version accessible on a device.
10. Not Checking Expiration Dates
Oregon permits are valid for limited periods—trip permits last 10 days, oversize/overweight permits vary.
-
Mistake: Using an expired permit during a move.
-
Solution: Mark expiration dates in your dispatch software or compliance calendar.
