1. Applying for the Wrong Type of Permit
One of the most common mistakes is confusing a trip permit with other trucking credentials. A Washington trip permit is not the same as a temporary fuel permit, an International Registration Plan (IRP) registration, or an International Fuel Tax Agreement (IFTA) license.
Each credential serves a different purpose:
-
Trip permit: May provide temporary authority to operate a vehicle that lacks the required registration credentials, subject to Washington's rules.
-
Temporary fuel permit: May allow qualifying carriers to operate temporarily without an IFTA license or other applicable fuel-tax credentials.
-
IRP registration: Applies to qualifying vehicles operating in multiple jurisdictions under apportioned registration.
-
IFTA license: Covers fuel-tax reporting for qualifying vehicles operating across participating jurisdictions.
Before applying, determine which requirement applies to your truck and intended operation.
2. Providing Incorrect Vehicle Information
Incorrect vehicle information can create problems during the application process or during a roadside inspection. Applicants should carefully verify all required details before submitting their request.
Depending on the application, relevant information may include:
-
Vehicle identification number (VIN).
-
License plate number and issuing jurisdiction.
-
Vehicle make and model.
-
Registered owner or carrier information.
-
Vehicle weight and other required operating details.
Always compare the information entered on the application with the vehicle's registration documents and other official records.
3. Entering Incorrect Permit Dates
Another mistake is entering an incorrect travel date or assuming a permit is valid for longer than its authorized period.
Before applying, confirm the intended travel date and the permit's validity period. Make sure the vehicle will complete the planned operation within the permit's authorized dates and conditions.
Do not assume a permit can be used retroactively or extended automatically. Verify the current Washington requirements before beginning your trip.
4. Confusing Trip Permits With Fuel Permits
A trip permit does not automatically satisfy fuel-tax requirements. Likewise, a temporary fuel permit does not replace vehicle registration or trip permit requirements.
A carrier may need one or both credentials, depending on the vehicle, its registration status, fuel-tax credentials, and planned operation.
For example, an out-of-state truck traveling through Washington may need to assess its temporary registration requirements separately from its IFTA or temporary fuel permit obligations.
5. Failing to Check Vehicle Eligibility
Not every commercial vehicle or operating situation necessarily qualifies for the same temporary permit. Eligibility can depend on the vehicle's registration status, weight, configuration, and intended use.
Before applying, confirm that the permit is appropriate for the specific vehicle and trip. If the vehicle is subject to additional registration, weight, or operating requirements, a trip permit alone may not be sufficient.
6. Waiting Until the Last Minute
Waiting until the truck is ready to depart can create unnecessary pressure. Application issues, missing documents, payment problems, or misunderstandings about eligibility may delay the trip.
Carriers should review their requirements before dispatching a vehicle and obtain any required authorization before operating. Build enough time into the process to resolve potential problems.
7. Failing to Carry Permit Documentation
Obtaining a permit is only part of the process. Drivers should ensure that the required permit documentation is available in the form accepted by Washington authorities.
Before departure:
-
Confirm that the permit details are correct.
-
Check the effective and expiration dates.
-
Ensure the document is accessible to the driver.
-
Follow any display, possession, or recordkeeping requirements.
-
Keep supporting registration and carrier documents available when required.
Drivers should not assume that an application confirmation is equivalent to an issued permit.
8. Overlooking Weight and Route Restrictions
A trip permit does not automatically authorize overweight, oversize, or otherwise restricted vehicle operations. Commercial vehicles may be subject to separate size, weight, axle, route, and bridge restrictions.
If a truck carries an unusually heavy load or exceeds standard dimensions, check whether additional permits or approvals are necessary. Verify that the planned route is suitable for the vehicle and load.
9. Using an Unreliable Application Source
Carriers should verify that they are applying through an authorized channel and that the permit meets Washington's requirements.
An unofficial website may provide outdated information, charge additional service fees, or fail to explain the difference between a permit application and an issued authorization.
Check the Washington State Department of Licensing or Washington State Department of Transportation, as applicable, for official requirements and current procedures.
10. Failing to Verify the Issued Permit
Even after receiving a permit, applicants should review it before the vehicle begins operating.
Check the following details:
-
Correct vehicle and carrier information.
-
Correct permit type.
-
Valid dates.
-
Applicable vehicle or trip restrictions.
-
Any special conditions attached to the authorization.
If you discover an error, contact the issuing authority or authorized provider to determine how it should be corrected before travel.
