What Is A Washington 3-Day Trip Permit?
The trip permit provides temporary Washington vehicle licensing for a specific vehicle. Under WSDOT guidance, it permits up to 40,000 pounds for a single vehicle and up to 80,000 pounds for a combination vehicle, subject to applicable legal weight requirements.
The permit is valid for three consecutive days, beginning on the date specified for its use. A vehicle generally cannot use more than three trip permits during a 30-day period.
Who May Need A Trip Permit?
A trip permit can be relevant when a commercial vehicle needs to operate in Washington temporarily without the appropriate Washington licensing.
WSDOT guidance identifies situations involving commercial vehicles such as:
- A 2-axle vehicle with a gross or registered weight over 12,000 pounds
- A 3-axle vehicle, regardless of weight
- Trucks or trailers that lack the required licensing or registration
- A vehicle whose licensed weight is insufficient for the load being carried
Out-of-state vehicles that are properly prorated with Washington generally do not need a separate Washington trip permit.
Washington Trip Permit Weight Limits
The standard trip permit allows:
| Vehicle | Maximum legal weight under trip permit |
|---|---|
| Single vehicle | Up to 40,000 lbs. |
| Combination vehicle | Up to 80,000 lbs. |
These are licensing/legal-weight limits, not authorization to exceed applicable axle, tire, bridge, or other weight restrictions. A separate oversize/overweight permit may be required for qualifying movements.
How Much Does A Washington Trip Permit Cost?
The underlying trip permit fee is $95.
How Long Is The Permit Valid?
A Washington trip permit is valid for three consecutive days. The permit must be properly completed before the vehicle operates on a public highway.
It is important to enter the vehicle information and dates accurately. WSDOT states that corrections to information such as the date, license number, or VIN can invalidate the permit.
How Many Trip Permits Can A Truck Use?
The same vehicle is generally limited to three trip permits within any 30-day period. This restriction means a trip permit is intended for temporary operation rather than as a substitute for ongoing vehicle registration.
