Washington Trip Permit: Cost, Rules & How to Get One
Here’s a scenario that plays out more often than it should.
A driver crosses into Washington state, fully loaded, tight on time. They’ve got their paperwork from the last state. They assume Washington works the same way. It doesn’t.
By the time a DOT officer flags them down near Spokane or at a weigh station on I-90, the cost of that oversight is no longer just a permit fee. It’s a fine, a delay, possibly a load hold — and an argument with dispatch that nobody wants to have.
Washington trip permits are not complicated. But they’re specific. And the rules around them trip up even experienced carriers who run through the state regularly.
This page covers everything you actually need to know: what the permit is, when you need it, what it costs, where it breaks down, and how our team at Compare Transport LLC handles it for carriers who’d rather just be moving freight.
What Is a Washington Trip Permit?
A Washington trip permit is a temporary commercial vehicle license issued by the Washington Department of Licensing (DOL) or WSDOT that allows a vehicle to legally operate on Washington public highways for 3 consecutive days. It substitutes for standard tonnage licensing when a vehicle is unregistered, under-licensed, or entering the state without IRP apportioned registration. Cost: $36 per permit (state-issued via DOL agents).
A Washington trip permit — officially called a trip license under Washington state law — is not the same as an oversize/overweight permit. It is a temporary licensing instrument, not a dimensional or weight exception permit. Think of it as a short-term registration proxy: it gives a commercial vehicle the legal right to be on the road in Washington when its normal registration or apportioned credentials are absent, expired, or insufficient.
The permit is governed primarily by RCW 46.44.030 and administered jointly by the Washington State Department of Licensing (DOL) and the Washington State Department of Transportation (WSDOT).
Two distinct scenarios call for a Washington trip permit:
- Out-of-state carriers entering Washington without valid IRP (International Registration Plan) apportioned registration for Washington.
- In-state operators whose vehicle is currently unlicensed or whose registered tonnage is insufficient for the load they are carrying.
How Does a Washington Trip Permit Work?
A Washington trip permit works by temporarily assigning state licensing to a specific vehicle (identified by VIN and plate number) for exactly 3 consecutive days. The permit must be completed, signed, and dated before the vehicle moves. It applies per-vehicle, covers legal weight only, and cannot be transferred to another truck or extended past its expiration date.
Each trip permit is tied to a single vehicle by VIN and license plate. The moment you write in the start date and sign it, the 3-day clock starts. Here is what that means operationally:
- Duration: 3 consecutive calendar days (72 hours) from the date entered on the permit.
- Scope: Valid on all Washington state public highways.
- Non-transferable: You cannot move a signed permit from one truck to another. Transfers are only allowed on oversize/overweight permits (max one transfer per permit via DOT Form 560-047), not trip permits.
- Non-extendable: You cannot purchase a “second permit” to stack on top of an expiring one for the same vehicle in most circumstances.
- Paper requirement: The signed, completed, physical (or printed) permit must be in the vehicle cab at all times during the trip. Per WSDOT guidance, digital-only copies on a phone may not suffice — print and sign before operating.
Washington Trip Permit Cost Breakdown
A standard Washington trip permit costs $36 total when purchased through DOL-authorized agents ($25 base permit fee + $11 service fee). Out-of-state commercial carriers using WSDOT-channel permits may see fees around $95 depending on the issuing agent. Fuel permits (IFTA-related) are separate at $33.
Understanding Washington’s trip permit cost requires knowing which agency is issuing it and for what purpose:
Permit Type | Base Fee | Service Fee | Total |
Standard 3-Day Trip Permit (DOL) | $25 | $11 | $36 |
Fuel Permit (non-IFTA entry) | $30 | $3 | $33 |
Commercial Trip Permit (out-of-state, WSDOT channel) | $95 | Varies | $95+ |
Oversize Dimension-Only (up to 3 days) | $10 | — | $10 |
Overweight Permit (under 100,000 lbs) | $14 min | Weight-based | Varies |
Overweight Permit (over 100,000 lbs) | $4.25 base | +$0.50/5,000 lbs over 100K | Calculated |
Important fee notes:
- Authorized vehicle licensing agents may charge additional service fees on top of the DOL base fees.
- The $25/$36 figure applies specifically to in-state DOL-issued permits for temporary operation of unlicensed or under-licensed vehicles.
- Out-of-state carriers using the WSDOT commercial permitting channel (for vehicles not registered under IRP) should budget approximately $95 per permit.
- There is no bulk or multi-permit discount for trip permits — each trip requires its own permit.
Who Needs a Washington Trip Permit?
You need a Washington trip permit if you are operating a commercial vehicle in Washington and your vehicle is (1) unlicensed or has expired registration, (2) registered but lacks sufficient tonnage for the current load, or (3) entering Washington from another state without valid IRP apportioned registration covering Washington.
You NEED a trip permit if:
- Your truck has expired tabs or no current Washington registration.
- Your registered gross vehicle weight (GVW) is lower than what your load requires for this trip.
- You are an out-of-state carrier whose apportioned IRP registration does not list Washington as a jurisdiction.
- You purchased a vehicle recently and haven’t completed permanent registration yet, but need to move it.
- You are operating a leased or borrowed vehicle that hasn’t been titled or licensed in Washington.
You do NOT need a trip permit if:
- Your vehicle carries valid Washington registration or full IRP apportioned plates covering Washington.
- Your vehicle is already properly licensed at the required tonnage for the load.
- You are moving a non-commercial vehicle under 26,000 lbs GVW (different rules apply).
- You have valid International Registration Plan (IRP) credentials with Washington listed — no trip permit needed for regular commercial travel.
Critical distinction: A trip permit is a licensing/registration substitute, not a size or weight exception. If your load is also oversize or overweight beyond legal limits, you will need both a trip permit AND a separate WSDOT oversize/overweight permit.
Weight Limits Under a Washington Trip Permit
The weight a trip permit authorizes depends on the vehicle configuration:
Vehicle Configuration | Maximum Legal Weight Under Trip Permit |
Single-unit vehicle (straight truck) | 40,000 lbs |
Combination vehicle (truck + trailer) | 80,000 lbs |
These are the maximum legal (licensed) weights — not overweight exception weights. If your actual load exceeds these thresholds, a trip permit alone is not sufficient. You would need a separate overweight permit from WSDOT, which uses a mileage-and-axle-spacing fee formula under RCW 46.44.034.
Washington’s standard legal limits for reference (no permit required if you stay within these):
- Width: 8 feet 6 inches
- Height: 14 feet
- Length: 53 feet for trailers; 75 feet overall combination
- Single axle weight: 20,000 lbs
- Tandem axle weight: 34,000 lbs
- Gross vehicle weight: 80,000 lbs (federal bridge formula applies)
Trip Permit vs. Other Washington Commercial Vehicle Permits
This is one of the most confusing areas for carriers entering Washington. Here is a clear side-by-side comparison:
Feature | Trip Permit | OS/OW Permit | Fuel Permit | Annual Blanket Permit |
Purpose | Temporary licensing/registration | Size or weight exception | IFTA tax compliance | Recurring oversize loads |
Issued by | DOL / WSDOT agents | WSDOT | DOL | WSDOT |
Duration | 3 consecutive days | Per trip or annual | 3 consecutive days | Up to 1 year |
Cost | $36 (DOL) / ~$95 | $10–$4.25+ (weight-based) | $33 | Varies by category |
Who needs it | Unlicensed/under-licensed vehicles | Loads exceeding legal dimensions/weight | Non-IFTA carriers entering WA | Frequent OS/OW operators |
Covers oversize? | ❌ No | ✅ Yes | ❌ No | ✅ Yes (specific categories) |
Transferable? | ❌ No | ✅ Yes (once, via Form 560-047) | ❌ No | ❌ No |
Self-issuable? | Via authorized agents | ✅ WSDOT self-issue portal | Via DOL agents | Via WSDOT |
Key takeaway: Many carriers need more than one permit type for a single trip. A wide load on an unlicensed vehicle needs a trip permit AND an oversize permit. A non-IFTA carrier with a legal-weight load needs a trip permit AND a fuel permit if operating diesel over 26,000 lbs GVW.
How to Get a Washington Trip Permit: Step-by-Step
Step 1: Confirm You Need a Trip Permit
Before purchasing a trip permit, verify that your vehicle does not already have valid IRP apportioned registration that includes Washington as a registered jurisdiction. Also confirm that your registered weight or tonnage is insufficient for the intended trip. Purchasing a trip permit when valid credentials already exist can result in unnecessary expenses.
Step 2: Gather Your Vehicle Information
Have the following information ready before applying:
- Vehicle Identification Number (VIN) – ensure it is entered exactly as shown on the vehicle records.
- License plate number – including out-of-state plates.
- Vehicle configuration – single unit or combination vehicle.
- Intended travel dates – including the start date and the three consecutive days covered by the permit.
- Carrier name and contact information.
Step 3: Choose Your Purchase Method
Select the most convenient permit acquisition channel. Online purchasing is generally the fastest option for most carriers. If you need assistance obtaining a Washington Trip Permit, CompareTransport LLC can help process permits quickly and efficiently.

Step 4: Complete the Permit Application Accurately
Accuracy is essential when completing a Washington Trip Permit.
- Enter the VIN, license plate number, travel dates, and carrier information exactly as required.
- Do not use abbreviations unless specifically permitted.
- Any corrections, alterations, or white-out markings may invalidate the permit.
- If an error is made, a new permit must be purchased.
- Ensure all required fields are completed before submission.
Step 5: Sign and Date the Permit
The permit must be signed and dated by the driver or an authorized representative before the vehicle begins operating. An unsigned permit is considered invalid and may result in penalties during enforcement inspections.
Step 6: Keep the Permit in the Vehicle
Print the permit and keep a copy inside the vehicle at all times during the permitted trip. Although Washington has adopted certain digital permitting options for oversize and overweight loads, carriers should verify current trip permit requirements before travel.

Step 7: Verify Additional Permit Requirements
If your vehicle or load exceeds Washington’s legal size or weight limits, you must obtain the appropriate Oversize/Overweight (OS/OW) Permit in addition to your Trip Permit before beginning your journey.
Both permits must be carried in the vehicle and be available for inspection by enforcement officers upon request.

Common Mistakes That Invalidate Your Permit
These errors are documented by WSDOT and routinely cited in roadside enforcement:
- Errors or corrections on the permit face. Any crossed-out information, white-out, or written-over text voids the permit immediately. Purchase a replacement if you make any mistake.
- Not printing the permit before operating. A permit number in an email or on a phone screen is not equivalent to a completed, signed paper permit for trip licenses.
- Entering the wrong start date. The 3-day validity period begins on the date written on the permit — not the date of purchase. If you buy it Thursday and write Friday as the start date, you are not covered on Thursday.
- Using a trip permit when valid IRP registration already covers Washington. This can raise compliance flags suggesting the carrier is attempting to avoid proper registration requirements.
- Assuming the trip permit covers oversize dimensions. Carriers frequently receive citations because they obtained a trip permit for weight but did not realize their load width also required a separate WSDOT oversize permit.
- Attempting to reuse a signed permit. Once used, a trip permit cannot be reused for a subsequent trip, even if all dates, vehicle info, and routes are identical.
- Not verifying out-of-service status. If your vehicle or carrier has an active Washington out-of-service order, a trip permit cannot legally authorize operation. Confirm your compliance status with WSDOT before purchasing.
Expert Tips for Carriers & Owner-Operators
Tip 1: Budget both permit types on every non-IRP entry. Out-of-state carriers who don’t operate under IRP should budget for both a trip permit (~$95) and a fuel permit ($33) on every Washington entry if running diesel over 26,000 lbs GVW. Forgetting the fuel permit is a separate, additional violation.
Tip 2: Use the WSDOT Bridge Clearance Map before every OS/OW move. If your load requires an oversize permit in addition to a trip permit, always verify bridge clearances using WSDOT’s Bridge Clearance Map tool before finalizing your route. A permitted load that can’t clear a bridge midway is a costly mistake.
Tip 3: Get IRP registration if you enter Washington more than twice a year. At $95 per trip permit entry, an operator making more than 3–4 Washington entries annually should strongly consider obtaining IRP apportioned registration with Washington as a listed jurisdiction. The break-even point comes quickly.
Tip 4: Confirm holiday travel restrictions. Under WAC 468-38-075, vehicles operating under oversize/overweight special permits may be restricted from Washington state highways on certain holidays. Trip permits themselves don’t carry this restriction, but if you also hold an OS/OW permit, verify holiday operating windows before scheduling a move on or near a major holiday.
Tip 5: Keep a permit log. WSDOT enforcement can review your permit history. Carriers who use trip permits repeatedly for the same vehicle — without moving toward permanent IRP registration — may attract scrutiny. Document your operational reasoning.
Tip 6: Know the difference between the DOL and WSDOT permit programs. The DOL handles standard trip permits (vehicle licensing). WSDOT handles oversize, overweight, superload, and fuel permits. For a complex move, you may be purchasing from both agencies on the same trip. Confirm your needs with both agencies or use a permit service that handles both.
Penalties for Operating Without a Permit in Washington
Washington takes commercial vehicle compliance seriously. Operating without the required permits can result in:
- First overweight offense: Minimum $50 base penalty, plus weight-based surcharges calculated per 1,000 lbs overweight.
- Second overweight offense: Minimum $75 base penalty.
- Third and subsequent offenses: Minimum $100 base penalty plus potential registration suspension.
- Second violation within 12 months (same power unit): Minimum $150 penalty AND mandatory registration suspension of at least 30 days.
- Operating without a trip permit (unlicensed vehicle): Separate citation under RCW 46.44 with fines plus potential vehicle impound.
- No fuel permit (non-IFTA carrier): Separate tax compliance violation with penalties calculated on estimated fuel tax owed.
Beyond direct fines, operating without proper permits in Washington can affect your carrier’s FMCSA Safety Measurement System (SMS) score, which influences CSA (Compliance, Safety, Accountability) ratings — a long-term consequence that impacts contracts and insurance rates.
