Washington Oversize and Overweight Permits

Washington Oversize and Overweight Permits

WSDOT eSNOOPI Pro permits, certified pilot/escort vehicles, 23 commuter curfew segments, mountain pass traction signs and ferry approvals

Quick answer

What does a Washington oversize permit cost per trip?

A WSDOT single-trip permit for width, height or length alone costs $10 and covers one route for up to 3 days (RCW 46.44.0941). Overweight is charged per mile of state highway by the pounds over legal capacity, from $0.07 a mile below 10,000 lb over to $4.25 a mile at 100,000 lb over, with a $14 minimum. Routine permits are self-issued at any hour in eSNOOPI Pro.

Updated October 2026 by the HTS Logistics broker team (FMCSA MC# 1178470).

Checked October 2026; the issued permit controls

Washington sets no flat 80,000 lb gross cap, unlike most states in our oversize permits by state guide: its RCW 46.44.041 axle-spacing table climbs to 105,500 lb, reached for example by 9 axles spread over 60 ft or 6 axles at 86 ft or more. Legal height is 14 ft statewide (RCW 46.44.020), and escorts start early, with two certified pilot/escort vehicles on any load over 11 ft wide on a two-lane highway (WAC 468-38-100(1)(a)).

HTS Logistics arranges heavy haul trucking through Washington as a licensed broker (MC 1178470). A booked carrier hauls the load, and we order the WSDOT permit, request city or county approval for any leg off state routes and hire pilot/escort operators who hold a Washington certificate or one of the eight out-of-state certifications WSDOT accepts. WSDOT will not issue permits over the phone, and permits that need its approval are processed within 3 business days.

When Washington requires a permit and how to get one

WSDOT Commercial Vehicle Services (CVS) in Tumwater issues permits for state highways, including state routes through cities, under RCW 46.44.090–.096 and chapter 468-38 WAC, and the Washington State Patrol enforces them. Most routine permits are self-issued 24/7 in eSNOOPI Pro, up to 16 ft wide, 16 ft high, 125 ft of trailer plus load and 200,000 lb, for tractor-trailer combinations only (jeeps and boosters allowed, doubles not), and weight permits need an axle spacing report number. Private permit agents and the WSDOT offices in Colfax and Spokane also sell permits; ports of entry do not, so the permit is bought before the load enters Washington.

A single-trip permit is route-specific and good for one trip over up to 3 days. The signed permit, or an electronic copy WSDOT can verify in eSNOOPI, rides in the power unit, on a screen of at least 3.5 by 5 in for routing permits (WAC 468-38-050(4)). Routine permit widths stop at 14 ft on two-lane state highways outside cities, 20 ft on barrier-divided multilane highways and 32 ft on undivided ones (RCW 46.44.092), and permitted axles may carry 22,000 lb single or 43,000 lb on two axles 3 ft 6 in to under 7 ft apart. Signing the application affirms at least $750,000 of liability insurance for the move (WAC 468-38-050(4)(c)).

100,000 $4.25, plus $0.50 a mile for each 5,000 lb or part above 100,000 lb

WSDOT measures the overage against the vehicle's registered weight, counts state-highway miles only (county and city segments still go on the permit) and rounds the total to the nearest dollar.

For example, a machine 32,000 lb over legal capacity on 200 miles of state highway pays $0.49 × 200, or $98, and no $10 dimension fee is added, because an oversize-and-overweight load pays only the overweight fee. Agents keep $3.50 of each permit fee, and WSDOT's pages do not say whether they add a service charge of their own. WSDOT offices take cash or check only, self-issuing costs nothing extra, and refunds go only to permits issued in error, on Form 560-024 within 60 days.

Escort and pilot car rules in Washington

Washington certifies pilot/escort operators: a driver licensed in Washington carries a WSDOT certificate card from an 8-hour course with an 80 percent written test, renewed every 3 years with a 4-hour course, and operators licensed elsewhere may use an Arizona, Colorado, Georgia, Minnesota, North Carolina, Oklahoma, Utah or Virginia certification, as our pilot car requirements by state page compares. WAC 468-38-100(1) sets the triggers, and WSDOT may add escorts to any move.

Washington pilot/escort triggers (WAC 468-38-100(1), eff. 3/25/2023)
LoadEscort requirement
Over 11 ft wide, two-lane highway 2 escorts, one in front and one at the rear (a)
Over 14 ft wide, multilane highway 1 rear escort (b)
Over 12 ft wide on a multilane highway when height already needs a front escort 1 rear escort added to the front height-pole car (i)
Over 20 ft wide, multilane undivided highway 2 escorts, front and rear (c)
Trailer plus load over 105 ft, or rear overhang over one-third of trailer plus load, two-lane 1 rear escort; the permit may allow a riding flag person instead (d), (3)
Trailer plus load over 125 ft, multilane 1 rear escort (e); the load is also a superload
Front overhang over 20 ft from the steer axle, two-lane 1 front escort (f)
Rear overhang over 20 ft on a single-unit vehicle, two-lane 1 rear escort (g)
Height over 14 ft 6 in 1 front escort on all highways with a height pole set 3–6 in above the load (h), (14); manufactured housing only over 15 ft
Driver cannot see 200 ft behind in the mirrors 1 rear escort (j)
Length-only superloads on the Interstate A rear escort alone, except front and rear on I-5 MP 0–9 and all of I-205, I-5 MP 119–208, all of I-405, I-90 from Seattle to MP 22, I-90 around Spokane and I-82/I-182 in the Tri-Cities (Permit Desk Guide 5-5)
Washington State Patrol No fixed trigger; set case by case for superloads, and WSP gets 48 hours' notice of building moves (WAC 468-38-405(6), -360(10))

A Washington escort vehicle is a car, van or two-axle truck of 16,000 lb GVWR or less, 60–102 in wide and towing nothing, with at least one amber light above the roofline visible 500 ft and a roof sign reading OVERSIZE LOAD at least 5 ft by 10 in (the Permit Desk Guide says 14,000 lb and two lights; the WAC governs). It carries an 18 in STOP/SLOW paddle, 3 reflective triangles, a 5 lb B,C extinguisher and a copy of the permit with all its conditions, and the rear car keeps within one-half mile of the load. For-hire operators carry $100,000/$300,000 bodily injury and $50,000 property damage cover. Escort-required loads do not convoy without WSDOT authorization, and the truck carries a two-way radio.

Travel times, curfews and holidays

Washington has no blanket daylight rule: loads no more than 12 ft wide and 14 ft 6 in tall, within 105 ft overall, may move at night without special approval (WAC 468-38-075(3)), and larger loads need a permit marked 'Night movement approved' (WAC 468-38-175(3)).

  • Night approvals: requests go to CVS with a justification, the route and the hours, and CVS replies by letter with times and escort conditions; self-issued requests over 12 ft wide, 14 ft 6 in high or 105 ft long wait for WSDOT approval within 3 business days. Night loads need 49 CFR 393.11 lighting and still obey the commuter curfews.
  • Commuter curfews, Monday–Friday: 23 segments around Seattle-Everett, Tacoma, Olympia, Vancouver, Kelso and Spokane close to signed loads at set hours. All of I-405 and I-90 from I-5 to I-405 shut both ways 6–9 AM and 3–7 PM, for example, and Tacoma's I-5 from Exit 118 to SR 512 6:30–8:30 AM and 4–6 PM. A load that is over width only, and no wider than the segment's listed width (10 ft on most, 9 ft on two, 11 ft 2 in on Spokane's I-90), is exempt (Form 560-002).
  • Weekends: no statewide weekend ban appears in WAC 468-38-175, and the commuter curfews run on weekdays only, but a holiday window can fall on a weekend.
  • Visibility and weather: no permitted move at visibility of 1,000 ft or less (WAC 468-38-095(5)), and the night rule separately bars moves at 500 ft or less and on snow, ice, mudslides or water. Oversize loads also leave the road when compact snow and ice require chains, and resume only once the nearest WSDOT or WSP office clears them.
  • Speed: permitted loads run at the posted truck speed unless the permit sets lower, hold 25 mph while on a two-lane shoulder letting traffic by, and void the permit by exceeding a speed it states (WAC 468-38-175(5)).
  • Exempt from curfews and holidays: WAC 468-38-075 permits (56 ft single trailers, 68 ft doubles, 61 ft non-divisible loads, tarping systems to 9 ft) and overweight-only loads that hold posted speeds.
Washington holiday restrictions, 2026 and New Year's Day 2027 (computed from WAC 468-38-175(1))
HolidayNo oversize movement on state highways
New Year's Day From noon Wed Dec 31, 2025, and all day Thu Jan 1
Memorial Day From noon Sun May 24, and all day Mon May 25
Independence Day (a Saturday) From noon Fri Jul 3, and all day Sat Jul 4
Labor Day From noon Sun Sep 6, and all day Mon Sep 7
Thanksgiving and the day after From noon Wed Nov 25, and all day Thu Nov 26 and Fri Nov 27
Christmas From noon Thu Dec 24, and all day Fri Dec 25
New Year's Day 2027 From noon Thu Dec 31, 2026, and all day Fri Jan 1, 2027

WSDOT publishes no dated schedule, so we applied the rule: from noon the day before through the holiday (Form 560-002 says 'the afternoon' before). The WAC says loads 'may be restricted', while WSDOT's form applies it as a ban on all overdimensional loads and on overweight loads that cannot keep up with traffic. The rule says nothing about observed weekday holidays.

Washington emergency load restrictions for freeze-thaw

Washington has no calendar frost law. When freeze-thaw or a similar emergency threatens a state highway, WSDOT must restrict or close the segment without delay (RCW 46.44.080; WAC 468-38-080), and the limit is legal only while signs stand at each end and at every intersecting state highway. Instead of axle weights, the restriction caps load per tire by tire size, a different method from the axle-percentage programs on our frost laws by state page.

  • Two levels: under an Emergency restriction an 11-22.5 or 11-24.5 tire carries 4,000 lb and a 12-22.5 or larger 4,500 lb; under a Severe Emergency restriction the same tires drop to 2,750 lb and 3,000 lb (WAC 468-38-080(2)). A truck on 10:00 x 20 or 11:00 x 22.5 tires or larger may still put 10,000 lb on the front axle, and restricted speeds are posted with the signs.
  • Permits do not override it: an oversize/overweight permit does not exempt a load (Permit Desk Guide 7-7), temporary additional tonnage permits do not lift posted limits, and only vehicles on tires listed in the table run under permit. Special permits for perishables, school buses or goods local residents need come from WSDOT region offices, not eSNOOPI Pro.
  • Counties and cities: local agencies restrict their own roads by ordinance once signs are up. Spokane County keeps an online list of weight-restricted roads in thaw season and, per its Jan 30, 2026 release, issues no permits for them except in emergencies.
  • Dates: neither WSDOT nor any county published 2026 start or end dates in the sources checked. On Oct 17, 2026 the first page of WSDOT's live truck restrictions list (355 entries) showed no emergency load restriction; the full list was not reviewed entry by entry.
  • Penalty: violating a posted limit costs at least $150, and a second violation by the same power unit within 12 months brings a registration suspension of at least 30 days (RCW 46.44.105(2)).

What catches carriers in Washington

Traction signs stop the permit

Where WSDOT displays TRACTION ADVISORY OVERSIZE VEHICLES PROHIBITED, VEHICLES OVER 10,000 GVWR CHAINS REQUIRED or ALL VEHICLES CHAINS REQUIRED EXCEPT ALL-WHEEL DRIVE, permitted movement is prohibited and entering the area violates the permit. From November 1 to April 1, trucks over 10,000 lb GVWR also carry chains plus two spares on routes such as I-90 from North Bend (MP 32) to Ellensburg (MP 101), US 2 from Index to Dryden and US 12 from Packwood to Naches.

WAC 468-38-095(8)-(9); WAC 204-24-050

The Vantage Bridge is closed to wide loads

From March 2, 2026 until about November 2026, the I-90 Vantage Bridge segment (MP 111–149.75) takes no load over 9 ft wide. eSNOOPI Pro routes around it by default, over I-82, I-182 and US 395 or the SR 970/US 97/US 2/SR 28/SR 281 alternates, and using the bridge at all takes a via point.

WSDOT Vantage Bridge truck restriction sheet (Feb 2026)

Restricted bridges carry no signs

Posted bridges are signed, but restricted bridges are not: their axle limits for permitted loads appear only on the permit, and crossing one over those limits voids it. WSDOT's live list showed 141 bridge and 214 road restrictions on Oct 17, 2026.

WAC 468-38-420; WSDOT Truck restrictions (live list)

OVERSIZE LOAD is the only wording

Every over-dimensional load shows an OVERSIZE LOAD sign at least 7 ft wide by 18 in high, black letters at least 10 in tall with a 1.4–1.5 in stroke on yellow, front and rear; the rule provides no other wording, so a WIDE LOAD banner does not meet it, which is not true everywhere, as our guide to load sign wording and sizes in other states shows. Red or orange fluorescent flags at least 18 in square mark the four corners of an overwidth load, lights take their place after dark, and the sign comes down whenever the load is not in transit.

WAC 468-38-155(3), (8); RCW 46.37.140

Self-issue privileges can be suspended

Officers may confiscate a permit for violated conditions, and each confiscation within 12 months costs a self-issuer its eSNOOPI privileges for 24 hours, then 15 days, 30 days and 1 year. Overweight fines start at 3 cents a pound for the first 4,000 lb over and reach $2,640 plus 30 cents a pound beyond 20,000 lb.

RCW 46.44.105; Permit Desk Guide 1-2

Superloads, ferries, tolls and the Columbia River

Past the self-issue envelope, Washington's extra steps come from the superload review, Washington State Ferries, the Puget Sound toll facilities and the movable bridges on the Columbia and Hood Canal.

Superloads

A non-divisible load over 200,000 lb, 16 ft high, 16 ft wide or 125 ft of trailer plus load is a superload (WAC 468-38-405(1)). File Form 560-022 at least 30 calendar days ahead over 200,000 lb (RCW 46.44.091(5)) or 7 days for a dimension-only superload, then apply for the single-trip permit, which only CVS issues. WSDOT may ask for proof that rail or water is not feasible, a loaded-vehicle schematic with axle loads and spacings, and a traffic control plan covering delay points, flaggers and rail crossings; loads over 300,000 lb go to pavement analysis, and loads over 16 ft high or 300,000 lb need a shipper's letter. No statutory superload fee exists, but the applicant may share analysis costs estimated in advance.

Tall loads

Over 14 ft, the carrier owns overhead clearance: the applicant checks or preruns the route and arranges any detour or temporary removal (WAC 468-38-070(1)(b)), using WSDOT's bridge height list and Bridge Vertical Clearance Trip Planner. WSDOT's signals office hears of loads over 16 ft, and over 16 ft 6 in the move waits for its approval (Permit Desk Guide 5-6). Rail crossing emergencies go to 1-888-877-7267.

Washington State Ferries

Vehicles registered over 80,000 lb GVW, over 13 ft 4 in high, over 8 ft 6 in wide or over 85 ft long contact the WSF Marine Division at 206-390-8543 at least 24 hours ahead, or a full work day for overweight loads. WSF issues a sailing-specific permit shown at the terminal, even for a load holding a WSDOT permit; hazmat is barred on passenger sailings, and charters need 7 days' notice.

Toll roads and lanes

Tolls rise with axle count on the SR 520 bridge, the SR 99 tunnel and the SR 16 Tacoma Narrows Bridge (toward Tacoma only), paid by Good To Go! pass or Pay By Mail, and the new SR 167 Expressway from the Port of Tacoma to I-5 in Fife stays free until axle-based tolling starts, which WSDOT puts at late 2026. Vehicles over 10,000 lb may never use the I-405 express toll lanes, and on limited-access highways with three or more lanes each way they stay out of the left lane.

Movable bridges and the Columbia River

WSDOT runs 17 movable bridges where marine traffic has right of way, among them the I-5 Interstate Bridge, whose openings are restricted weekdays 6:30–9 AM and 2:30–6 PM, and the SR 104 Hood Canal floating bridge, which generally closes when sustained wind tops 40 mph for 15 minutes. The I-5 bridge segment (MP 0–7.48) also closes to signed loads northbound 3–6 PM and southbound 6–9 AM, I-205 from the Oregon line northbound 4–7 PM and southbound 6–9 AM, and the SR 433 Lewis and Clark Bridge at Longview 6–9 AM both ways.

Heavy-haul corridors

RCW 46.44.0915 allows 105,500 lb for sealed international containers on SR 509 at the Port of Tacoma, 139,994 lb on US 97 from the Canadian border to the Oroville railhead, and 129,000 lb on SR 128/SR 193 from the Idaho line to the Port of Wilma. The statute sets the SR 509 corridor at MP 0.25–5.7 while the Permit Desk Guide says MP 0.25–3.88; the statute governs.

Local roads and ports of entry

A WSDOT permit does not authorize county roads or city streets, and not every county or city runs a formal permit system, so the road's owner gets a call; a city permit is not needed where the move stays on a state route through town (RCW 46.44.096). Commercial vehicles stop at open scales, including WSP ports of entry at Bow Hill (I-5 southbound), Ridgefield (I-5 northbound), Cle Elum (I-90 westbound), Spokane/Liberty Lake (I-90 westbound) and Plymouth/Kennewick.

Crossing into a neighboring state

  • South into Oregon over the I-5 or I-205 bridges: ODOT's Attachment H keeps loads over 14 ft off I-5 from Washington to MP 278 and off I-205 in the weekday morning and afternoon peaks (7 to 9, 4 to 6), and single-trip non-divisible loads pay a road use assessment of 10.9 cents per ESAL mile on top of the $8 permit fee, as our Oregon oversize permit rules explain.
  • East into Idaho on I-90 or US 12: ITD stops every oversize vehicle at each port of entry, starting at Huetter west of Coeur d'Alene, and keeps loads wider than 13 ft off I-90 between MP 0 and MP 17 during the morning and evening commute. Our Idaho oversize permits by route color page covers the escort map and the Lochsa corridor.

Washington oversize permit questions

Does Washington require certified pilot/escort drivers?

Yes. An operator with a Washington driver's license carries a Washington pilot/escort certificate card, earned through an 8-hour course from a WSDOT-approved provider with an 80 percent written test and renewed every 3 years with a 4-hour course. Operators licensed elsewhere may get the Washington card or use a certification WSDOT recognizes: Arizona, Colorado, Georgia, Minnesota, North Carolina, Oklahoma, Utah or Virginia (WAC 468-38-100(4)).

Which Washington oversize loads may travel after dark?

A load no wider than 12 ft, no taller than 14 ft 6 in and no longer than 105 ft overall, legal overhangs included, may move at night without special approval (WAC 468-38-075(3)). Larger loads need a permit stating 'Night movement approved', requested from CVS with a justification, the route and the hours; self-issued requests wait for WSDOT approval within 3 business days. Night moves need 49 CFR 393.11 lighting and still obey the commuter curfews.

What are WSDOT's commuter curfew hours for oversize loads?

They cover 23 segments around Seattle-Everett, Tacoma, Olympia, Vancouver, Kelso and Spokane on weekdays only, and the hours vary by segment and direction. All of I-405 closes to signed loads 6 to 9 AM and 3 to 7 PM both ways, for example, while I-5 from the Oregon line to I-205 closes northbound 3 to 6 PM and southbound 6 to 9 AM. Loads over width only, within the listed width, are exempt.

What is a superload in Washington?

Any non-divisible load over 200,000 lb, 16 ft high, 16 ft wide or 125 ft of trailer plus load (WAC 468-38-405(1)). Loads over 200,000 lb need a written application 30 calendar days ahead and dimension-only superloads 7 days, on Form 560-022, before the single-trip permit is requested. Only CVS issues superload permits, and WSDOT may require a traffic control plan, extra escorts or law enforcement vehicles.

How do I get a Washington oversize permit online?

Self-issue it in eSNOOPI Pro, which runs 24/7 for tractor-trailer loads up to 16 ft wide, 16 ft high, 125 ft of trailer plus load and 200,000 lb; weight permits need an axle spacing report number. Superloads and 8-tire axle permits over 43,000 lb tandem or 22,000 lb single go through CVS at 360-704-6340 or [email protected]. Ports of entry do not sell permits, and WSDOT offices take cash or check only.

Does an oversize load need its own permit for a Washington State Ferry?

Yes, above set sizes. Vehicles registered over 80,000 lb GVW, over 13 ft 4 in high, over 8 ft 6 in wide or over 85 ft long contact the WSF Marine Division at 206-390-8543 at least 24 hours ahead, or a full work day ahead for overweight loads. WSF issues a sailing-specific permit shown at the terminal, even when the load already holds a WSDOT oversize or overweight permit.

When must trucks carry chains in Washington?

From November 1 to April 1, vehicles over 10,000 lb GVWR carry enough chains, plus two extra, on routes including I-90 from North Bend to Ellensburg, US 2 from Index to Dryden, US 12 from Packwood to Naches and SR 410 from Enumclaw to Naches (WAC 204-24-050). Wherever WSDOT posts a chains-required or oversize-prohibited traction sign, permitted oversize movement stops, and entering the area violates the permit.

Routing a wide load over the Cascades?

Traction signs on I-90, the Vantage Bridge width limit and 23 commuter curfew segments each decide when a Washington load can roll. Give us the machine, its loaded width and height and the pickup and delivery points, and we will plan the WSDOT permit, the certified escorts and the carrier around those limits.
