Oklahoma Oversize & Overweight Permits filed with ODOT for you, 24/7

In Oklahoma, a load over 8 ft 6 in wide or 13 ft 6 in high needs an ODOT permit, and so does a truck over 80,000 lbs on the interstate or 90,000 lbs on other state highways. Permits go through ODOT's OkiePROS system. Send us the load and route: our permit desk quotes the price and files it for you.

Which permit you need

Oklahoma permits for oversize and overweight loads

  1. Wider than 8 ft 6 in or taller than 13 ft 6 in

    Oversize permit

    A single-trip ODOT permit for a non-divisible load past the legal width, height or length. On the interstate the load can be at most 16 ft wide.

  2. Heavier than the interstate or state highway limit

    Overweight permit

    For a non-divisible load over 80,000 lbs on the interstate, 90,000 lbs elsewhere, or the bridge formula. ODOT checks the route's bridges before it issues.

  3. Over both size and weight

    Oversize and overweight permit

    One permit covers both the size and the weight of the move. ODOT still charges each part as if the two permits were issued separately.

  4. Beyond ODOT's standard trucks

    Superload permit

    Any overweight load heavier than the standard trucks on ODOT's drawing OL-1. Unless the route was studied before, every bridge on it gets a structural analysis.

Routes and road rules

Where Oklahoma routes add their own rules

The road you take changes what the permit allows: interstates, state highways and turnpikes each play by different rules.

  1. Interstates through Oklahoma City, Tulsa and Norman

    No oversize loads on the interstates of Oklahoma, Tulsa and Cleveland counties from 7 to 9 a.m. and 3:30 to 6:30 p.m., Monday to Friday.

    Exception:The two miles of I-35 between SH 9 East and SH 9 West in Norman stay open.

  2. Interstates cap the width at 16 ft

    ODOT will not permit a load over 16 ft wide on the interstate for any part of the trip. Wider loads, up to 20 ft for dual-lane superloads, are routed on state highways.

    Escorts:Over 16 ft wide, front and rear escorts on every road.

  3. Green and red routes for overweight trucks

    ODOT keeps an Overweight Truck Permit Map: trucks matching drawing OL-1 can be permitted on green routes without a new bridge review; red routes cannot carry them.

    Off the map:A specific load route review, requested at least 5 working days ahead.

  4. Turnpikes are a separate authority

    Toll roads outside the state highway system belong to the Oklahoma Turnpike Authority. ODOT's permit rules apply there only with the Turnpike Authority's approval.

    Annual permits:Valid on state highway green routes only, never on the interstate.

Oklahoma industries

Oklahoma permits for the loads Oklahoma hauls

Beside the single-trip permit, ODOT has permits written for the state's wind, farm, oilfield and housing loads.

  1. Wind energy

    Turbine blades

    An annual envelope permit for trucks hauling wind turbine blades, with cargo up to 160 ft long. It is valid only while the truck carries blades.

  2. Farm and timber

    Round bales, raw forest products, soil conservation equipment

    Annual agriculture permits for each, with Oversize Load signs and flags. Forest products and soil conservation equipment stay off the interstate.

  3. Oilfield and farm trucks

    Weight variance

    Qualifying oilfield and farm trucks registered at the maximum rate may run 5% over the gross limit and 8% over the axle limits, off the interstate.

  4. Housing

    Manufactured homes and buildings

    Separate rules for manufactured homes, portable and industrialized buildings. Manufactured items over 16 ft wide need ODOT's special movement application.

What we check before filing in Oklahoma

  1. Book the Highway Patrol early

    When ODOT requires a Highway Patrol escort, it runs on a contract that can take two to four weeks. We flag it when we quote, not on moving day.

  2. 15 ft 9 in is the line to watch

    From 15 ft 9 in high you need escorts front and rear, a height pole and calls to every utility and railroad on the route. Send us the exact height.

  3. The length escort line moved to 90 ft

    Since July 2026 a front escort on two-lane highways starts above 90 ft, up from 80 ft. An 85 ft load that needed one before runs without it now; we quote by the current rule.

FAQ

Oklahoma oversize permit questions

What size and weight need a permit in Oklahoma?

A load over 8 ft 6 in wide or 13 ft 6 in high, past the legal length for its vehicle type, or over 80,000 lbs on the interstate and 90,000 lbs on other state highways. Axle limits and the federal bridge formula apply too.

How much does an Oklahoma oversize permit cost?

It depends on the size, weight and route; an oversize and overweight load pays for both parts. 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.

How wide can a load be before Oklahoma requires an escort?

Up to 12 ft wide runs without one. Over 12 ft you need one escort, over 14 ft two on two-lane highways, and over 16 ft two on every road. Height from 15 ft 9 in and length over 90 ft also bring escorts.

Are there rush-hour restrictions for oversize loads in Oklahoma?

Yes. Oversize loads may not use the interstates in Oklahoma, Tulsa and Cleveland counties from 7 to 9 a.m. and 3:30 to 6:30 p.m. on weekdays, and move only from 30 minutes before sunrise to 30 minutes after sunset. Overweight-only loads can run around the clock.

Does Oklahoma have an annual permit for oversize loads?

Yes. The annual envelope permit covers loads up to 12 ft wide, 14 ft high, 110 ft long and 120,000 lbs, on state highway green routes only and never on the interstate. A wind blade version allows cargo up to 160 ft.

What counts as a superload in Oklahoma?

Any overweight load heavier than the standard trucks on ODOT's drawing OL-1. It needs a bridge-by-bridge structural analysis unless the route was studied before, so plan extra time.

How does Route One GO get my Oklahoma permit?

Send us the truck, trailer, load dimensions, axle weights and route. Our permit desk checks the Oklahoma rules, files with ODOT in OkiePROS, and sends you the permit with a route map. Requests are taken 24/7.
