    General width: 8′6″

    Ordinary vehicle-and-load limit; safety-device, vehicle and load exceptions may apply.

    Loaded height: 13′6″

    Ordinary vehicle-and-load limit; listed exceptions and actual route clearances apply.

    NN semitrailer: 48′

    Federal National Network allowance for a tractor with one semitrailer. Longer trailers may qualify under state axle-position and route rules; local roads can differ.

    Overall length: No NN cap*

    *For a tractor with one compliant semitrailer on the National Network. Other combinations, trailers, projecting loads and local access have separate limits; see the state measurements below.

    Interstate weight: 80,000 lb*

    *Federal baseline, subject to the bridge formula, registration and postings: 20,000 lb single axle and 34,000 lb tandem. A particular configuration may have a lower limit; state grandfather allowances need verified spacing and route eligibility.

    Legal size

    Legal limits are 8′6″ wide and 13′6″ high. Length depends on the vehicle combination and exceptions.

    Weight limits

    Gross weight alone does not settle it in Wisconsin. Check each axle, group spacing, tires and wheels, gross weight, Class A or B roads, seasonal limits and bridges.

    Width

    Legal width is 8′6″. Load projections and Trans 276 exceptions are checked separately.

    Height

    Legal height is 13′6″.

    Axle limits with a permit

    With a permit: steering axle 20,000 lb, any other axle 35,000 lb. Single-trip permit maximums (form MV2600); the route can set lower weight limits. If adjacent axles are less than 42″ apart, the axle can carry no more than a single axle. Legal weights and multiple-trip axle limits are listed in their own cards.

    Legal axle and gross weights

    A permit is typically required above these weights: Any one wheel, or the wheels on one end of an axle: 11,000 lb. Truck-tractor steering axle: 13,000 lb. Single axle: 20,000 lb. Tandem axles: 34,000 lb. Gross on all axles: 80,000 lb. Class B highways: 60% of Class A limits.

    What official sources leave open13

    Where Wisconsin’s official sources disagree or say nothing, confirm with the agency before dispatch.

    • Wisconsin's official sources do not use a 'superload' category or publish a superload process or lead time. The closest are the region route review for single trips over 16′ wide and the bridge review over 150,000 lb (Trans 250.05). Trans 250.025 gives WisDOT 30 days to decide a complete application.
    • No official source fetched sets escort-driver certification, training or out-of-state reciprocity. Trans 252.04 only requires age 18+ and a license valid in Wisconsin.
    • The escort chart does not say how to set the height pole or where the pole car runs.
    • No official source fetched says whether an electronic copy of the permit is accepted. Trans 254.08 says to carry the permit in the vehicle.
    • No USDOT-number or operating-authority requirement was found for general OSOW permits. Only building mover (BM) permits state MC/LC authority and CDL requirements.
    • Conflict: the WisDOT hours page and hours chart (10-31-2024) add a 4–8 p.m. summer-Friday ban for loads over 12′ wide, 13′6″ high or 150′ long statewide. Trans 254.11(3) and form MV2605 (7/2024) apply the summer-Friday ban only in Columbia, Dane, Milwaukee, Rock and Waukesha counties. This guide follows the WisDOT page.
    • Conflict: Trans 250.05(1)(b) sets the bridge review fee at $10 per employee-hour; form MV2600 (6/2021) says $10.00 per review.
    • Conflict: Trans 254.04(5) allows one permit extension; form MV2605 (7/2024) says up to two extensions.
    • Conflict in the 2026 holiday PDF: the five-county page lists Wednesday Dec 30th 2026 for the New Year's 4–8 p.m. ban, but the statewide page says the ban starts at 'noon on Tuesday Dec 30th 2026'. Dec 30, 2026 is a Wednesday.
    • The 2027 restricted-travel holiday list is not published yet (WisDOT must publish it by November 30, 2026 under Trans 254.02(2)(c)). 2027 dates after January 1 are left out.
    • The two-trigger escort crews (wide and long) come from the colored cells of the WisDOT escort chart (dated 7/9/2018). The PDF text does not label each cell, so the quotes show only the chart headings.
    • WisDOT's permit page lists a 34,000 lb tandem and points to SP4075 (maximum weight limitations summary) and Wis. Stat. 348.15–348.18 for exceptions; SP4075 was not reviewed here.
    • No separate legal rear-overhang limit was found in the sources fetched; only the 4′ rear flag and lamp rule (Wis. Stat. § 347.20) applies.

    The rule in full5 official sources

    Travel hours

    Overweight-only loads can move 24/7 unless the permit says otherwise. For oversize loads, size limits, named counties, darkness, weekends, summer Fridays and holidays can stop a move. So can the Milwaukee Expressway and Madison Beltline rules.

    Check your route and date

    Overweight-only loads can travel 24/7 unless restricted. Oversize loads must check county, darkness, weekend, holiday, Milwaukee and Madison windows for their route and date.

    Current route restrictions

    Before leaving, check the 2026 holiday chart, named county limits, frozen and seasonal roads, emergency bridge notices, work zones, 511, weather and every permit condition.

    Hours for big loads

    A load over 12′ wide, 13′6″ high or 150′ long may not move: During the hours of darkness. 4–8 p.m. on Sunday. 4–8 p.m. on Fridays from the 4th Friday in May through Labor Day (per the WisDOT hours page). From noon Saturday until sunrise Sunday. From noon the day before until sunrise the day after each restricted-travel holiday.

    Smaller oversize: five counties

    Oversize loads within 12′ wide, 13′6″ high and 150′ long have no set hours in 67 counties unless the permit says otherwise. In Columbia, Dane, Milwaukee, Rock and Waukesha counties they may not move 4–8 p.m.: On Sunday. On Fridays from the 4th Friday in May through Labor Day. On any restricted-travel holiday. On the day before a restricted-travel holiday, except July 3 when it falls on a Saturday.

    Restricted-travel holidays

    WisDOT must publish each year's restricted-travel holiday list by November 30 of the year before. If no list is published, the rule's default list applies: January 1. Saturday and Sunday of Easter weekend. Last Monday in May and the Saturday and Sunday before it. July 4, and the Monday after if July 4 falls on a Sunday. First Monday in September and the Saturday and Sunday before it. Saturday and Sunday opening the gun deer season. Fourth Thursday in November, and the following Saturday and Sunday if that Sunday ends gun deer season. December 24, 25 and 31.

    Overweight-only loads

    A load that is overweight but not oversize may run 24 hours a day, including weekends and holidays, unless the permit says otherwise.

    Milwaukee County Expressway

    Over legal width, height or length on the Milwaukee County Expressway (except US 45 between W. Florist and W.

    On a single-trip permit over legal width, height or length, stay off US-12/US-18 between Verona Road and Stoughton Road 6–9 a.m. and 3–6 p.m., Monday through Friday.

    Bad weather voids the permit

    A single-trip permit is not valid while fog, smoke, heavy rain, snow, ice or wind make the move unsafe.

    Big-load holiday ban (statewide)
