Kansas Oversize & Overweight Permits filed with KDOT for you, 24/7

In Kansas, a load over 8 ft 6 in wide, 14 ft high or 80,000 lbs on the interstate (85,500 lbs on other roads) needs a KDOT permit, issued through K-TRIPS. A standard permit is good for 7 days, and permitted loads may move every day of the year, holidays included. Send us the load and route: our permit desk quotes the price and files it for you.

Routes and road rules

Where Kansas routes add their own rules

Western Kansas, the Turnpike and the triples network each put conditions on top of the KDOT permit.

  1. US-83 in western Kansas

    Loads 14 ft or wider, or 126 ft or longer, must share their live location while they run US-83.

    Since:KDOT's August 2024 letter to carriers.

  2. The Kansas Turnpike

    KDOT permits are not required on the Turnpike, which sets its own rules: no night travel over 8 ft 6 in wide, Turnpike pre-authorization over 12 ft wide or 125 ft long, and loads over 16 ft wide are rarely approved.

    Legal there:Double 53-ft trailers and 22,000 lbs on a single axle.

  3. Triples network

    Triples need a special vehicle combination annual permit and get on only at US-69 Alt in Baxter Springs, I-70 at Goodland and terminals near Turnpike toll booths.

    Not on:Holidays or holiday weekends.

  4. Weigh stations

    Commercial vehicles must stop at open weigh stations in Kansas, and a truck on a permit is no exception.

    Plan:Build scale stops into the drive time.

What we check before filing in Kansas

  1. Escorts that meet Kansas rules

    Kansas wants escort companies registered each year and every escort driver trained, and the Highway Patrol does not escort. We confirm the escort setup the permit calls for before filing.

  2. Is the Turnpike on the route?

    A Turnpike leg follows its own rules and access permits. We check whether your route uses it and plan the permits for that stretch separately.

  3. Holiday miles at the border

    Kansas permits run on holidays; Nebraska permits do not. When a holiday falls mid-trip, we plan where the load stops before crossing the line.

FAQ

Kansas oversize permit questions

Which dimensions make a Kansas load oversize?

Over 8 ft 6 in wide, 14 ft high, 45 ft for a single vehicle or 59 ft 6 in for a semitrailer. By weight, over 20,000 lbs on a single axle, 34,000 lbs on a tandem, 80,000 lbs gross on the interstate or 85,500 lbs on other roads.

How much does a Kansas oversize permit cost?

It depends on the permit, the size and weight, and the route; superloads need a bridge analysis. Put your route into our permit cost calculator for an estimate, or send us the load and our permit desk quotes the exact price before filing.

Can an oversize load move on Thanksgiving or Christmas in Kansas?

Yes. Kansas lets carriers move every day of the year, holidays included; oversize loads still keep to daylight. Triples on a special vehicle combination permit are the exception and stay parked on holidays and holiday weekends.

Can a Kansas standard permit cover more than one trip?

Yes, over the same route. A standard KDOT permit is good for 7 days, and the load may make multiple trips on that route inside the window. Superloads over 150,000 lbs get a single trip only.

Who is allowed to escort an oversize load in Kansas?

An escort company registered with the state for the year, with drivers who completed an approved escort training course. The Kansas Highway Patrol does not provide escorts.

Which loads must share their location on US-83 in Kansas?

Since KDOT's August 2024 letter to carriers, loads 14 ft or wider, or 126 ft or longer, must share their live location while on US-83 in western Kansas.

How does Route One GO get my Kansas permit?

Send us the truck, trailer, load dimensions, axle weights and route. Our permit desk checks the Kansas rules, files with KDOT in K-TRIPS, and sends you the permit with a route map. Requests are taken 24/7.
