Oklahoma Oversize Permit Cost: Worked Examples

Oklahoma writes one minimum permit fee into statute and then forks it three ways. A load that is only oversize pays the base. A load that is only overweight pays the base plus ten dollars for each 1,000 pounds it runs over the legal load limit. A load that is both pays two bases plus that same weight charge, because the permit rules issue a single permit for a combined move and price it as though two permits had been written. Distance never enters the arithmetic. Every current figure renders with its official source on the Oklahoma oversize and overweight permits page; this guide walks four moves through the fork so the schedule reads like a quote instead of a table. To check whether your load is oversize anywhere on the route in the first place, run it through the oversize permit cost estimator.

What an Oklahoma permit costs, component by component

• Oversize only: $40.00Permit Fees, the Oklahoma Size and Weight Permits fee schedule (Oklahoma Department of Transportation)Verified Aug 5, 2026 for a single trip or a month, whether the load is over on width, height or length.
• Overweight only: $40.00Permit Fees, the Oklahoma Size and Weight Permits fee schedule (Oklahoma Department of Transportation)Verified Aug 5, 2026 as the base, plus ten dollars for each 1,000 pounds over the legal load limit.
• Oversize and overweight: $80.00Permit Fees, the Oklahoma Size and Weight Permits fee schedule (Oklahoma Department of Transportation)Verified Aug 5, 2026 as the base, plus the same charge for each 1,000 pounds over.
• Multi-trip: $40.00Permit Fees, the Oklahoma Size and Weight Permits fee schedule (Oklahoma Department of Transportation)Verified Aug 5, 2026 per month, issued date to date, with a published ceiling once the months add up to a year.
• Delivery and payment: $2.00Permit Fees, the Oklahoma Size and Weight Permits fee schedule (Oklahoma Department of Transportation)Verified Aug 5, 2026 rides on any permit sent by fax or email under 47 O.S. Section 14-118(A)(3), and card payments add a 4 percent convenience fee.

The base comes from 47 O.S. Section 14-116(A), which sets a minimum fee for any permit issued under the size and weight chapter and adds ten dollars for each 1,000 pounds over the legal load limit. The doubling comes from the permit rules at OAC 730:50-5-3(11), which require a single permit to cover a load that is both oversize and overweight and price it as though two permits had issued. Permits are bought through OkiePROS, the department's online permit manager, and a company profile with a copy of the submitting person's driver license has to be on file before the first order.

Two consequences follow. Distance is free, so a fifteen mile move and a three hundred mile move cost the same, which is the opposite of Tennessee, Pennsylvania and New Mexico, where the overweight charge is billed by the ton mile and the route sets the bill. Compare the same load across states on the oversize permit costs by state table. And the combined rule runs the other way from Ohio's, where a movement that is both over width and overweight pays one processing fee and the overweight surcharge only. Price an Oklahoma wide-and-heavy move on an Ohio assumption and you are short a full base fee before the weight charge is counted.

Worked example 1: eleven feet wide at legal weight

A baler on a step deck running eleven feet wide, inside legal height, length and weight, is a one-charge permit: $40.00Permit Fees, the Oklahoma Size and Weight Permits fee schedule (Oklahoma Department of Transportation)Verified Aug 5, 2026 and nothing else moves it. The mileage does not, and neither does how far over legal the width sits, because Oklahoma's oversize fee has no width bands the way Tennessee's does. The legal width it crossed is 102 inches under 47 O.S. Section 14-103(A), measured with or without the load, and tire bulge and approved safety devices are excluded from that measurement.

What the fee schedule does not price is what actually shapes this day. Eleven feet sits under the escort line, which starts above twelve feet wide under OAC 730:50-5-18. But oversize movement is daylight only under 47 O.S. Section 14-101(F), a half hour before sunrise to a half hour after sunset, and permitted movement is banned outright on New Year's Day, Memorial Day, Independence Day, Labor Day, Thanksgiving and Christmas. The permit is cheap. The calendar is not.

Worked example 2: overweight only, and the route picks the overage

Oklahoma's legal gross is not one number. 47 O.S. Section 14-109(A) sets no flat figure: gross is whatever the federal bridge formula allows for the axle spacing, with no single axle over 20,000 pounds and no tandem set over 34,000 pounds. Two ceilings sit on top of the formula. On the interstate system an overweight permit is required above 80,000 pounds. Off it, 47 O.S. Section 14-101(E) lets a vehicle run to 90,000 pounds gross without one.

Take a load grossing 96,000 pounds on a spacing the formula allows to the ceiling. Off the interstate the overage is 6,000 pounds, six increments of 1,000, so the weight charge is sixty dollars on top of the base fee. Route the same load onto I-40 and the ceiling drops to 80,000 pounds: the overage becomes 16,000 pounds, sixteen increments, and the weight charge is a hundred and sixty dollars on top of the same base. Same truck, same load, same day, and the interstate leg costs a hundred dollars more in permit fees than the state highway one.

That is the arithmetic most out-of-state carriers get wrong in Oklahoma. They price the overage against 80,000 pounds everywhere, because 80,000 is the number their home state uses, and then either overpay on a US highway run or discover on the interstate that the permit they bought was written for a different ceiling. Read the route first, then count the increments.

One relief on this move: an overweight-only load is not subject to the daylight rule. 47 O.S. Section 14-101(F) applies to vehicles permitted for anything other than weight alone, so a heavy but legal-dimension load has continuous travel.

Worked example 3: wide and heavy, and where the second base fee lands

An excavator twelve feet six inches wide and grossing 96,000 pounds off the interstate is over on both counts, and this is where the fork bites. The move does not pay the oversize fee, and it does not pay the overweight fee. It pays the combined base, $80.00Permit Fees, the Oklahoma Size and Weight Permits fee schedule (Oklahoma Department of Transportation)Verified Aug 5, 2026, which is exactly double

$40.00Permit Fees, the Oklahoma Size and Weight Permits fee schedule (Oklahoma Department of Transportation)Verified Aug 5, 2026

because the rule prices one permit as two.

The weight charge does not change. Six increments of 1,000 pounds is still sixty dollars, added to the doubled base rather than to a single one. So the width, which cost nothing extra in example 1, costs a full extra base fee here purely because the load is also heavy.

The width also crosses the escort line. OAC 730:50-5-18 puts one escort on a load over twelve feet and up to fourteen feet wide, running in front on two-lane and super two-lane highways and behind on multi-lane highways. That escort is a certified job, not a friend in a pickup: 47 O.S. Section 14-120.1 requires anyone driving an escort vehicle for hire to hold a Department of Transportation escort certification and carry it for inspection, and Oklahoma's escort rules require at least $1,000,000 combined single limit commercial liability coverage with proof in the vehicle. The escort never appears on the permit invoice, and on a move like this it will cost more than every fee above it on this page combined.

Worked example 4: legal on the highway, oversize on the last mile

47 O.S. Section 14-103(B)(1) writes two legal heights rather than one: fourteen feet on any turnpike, interstate, US or state highway, and thirteen feet six inches on any county road. Most states publish one legal height and stop, so a ceiling that changes with the class of road is easy to read past, and the fourteen foot allowance looks like free headroom until the delivery address is rural.

A load riding thirteen feet nine inches is legal for the entire highway portion of the trip and becomes oversize the moment it turns onto a county road for the last mile. That turn buys a permit at the flat oversize fee, and it converts the whole move to daylight only. It also shifts liability: an operator whose load exceeds the height limit is liable for damage to any structure spanning the highway, which is why the department publishes an official state bridge vertical clearance map. Note that the Size and Weight Permits FAQ answers the height question more conservatively than the statute does, telling carriers a permit is needed above thirteen feet six inches, which is the county road figure rather than the highway one. The statute is the controlling text; the FAQ is the safe habit.

When the monthly permit beats the trip permit

The multi-trip permit is priced by the month rather than by the trip, at the same figure as a single trip, and it is issued date to date. The break-even is therefore one extra move: a month carrying two permitted trips has already paid for the month, and a carrier with a standing lane should be buying months instead of trips. The published cap stops the meter once the months reach a year, so the worst case for a year of continuous permitted movement is twelve months of the monthly fee.

Above that, Oklahoma sells a long roster of annual permits, and the spread across them is the widest thing on the fee sheet. Each one is written for a named use rather than sold as general coverage, so the question is never which is cheapest but which one your work fits. The special purpose annual oversize-only permit, for special mobilized machinery under 47 O.S. Section 14-103(C)(9)(b), is $10.00Permit Fees, the Oklahoma Size and Weight Permits fee schedule (Oklahoma Department of Transportation)Verified Aug 5, 2026. The longer combination annual, which doubles need only when the combination passes 80,000 pounds but stays under 90,000 pounds, is $20.00Permit Fees, the Oklahoma Size and Weight Permits fee schedule (Oklahoma Department of Transportation)Verified Aug 5, 2026. The annual round bale hay, tree length log or soil conservation permit is $25.00Permit Fees, the Oklahoma Size and Weight Permits fee schedule (Oklahoma Department of Transportation)Verified Aug 5, 2026, and it comes with a split most haulers miss: round baled hay eleven feet wide or less may use the interstate system, while raw forest products and soil conservation equipment may not. Special purpose annuals expire on December 31 each year rather than running date to date.

The headline annual sits at the other end. The Annual Envelope Vehicle Permit is

$4,000.00Permit Fees, the Oklahoma Size and Weight Permits fee schedule (Oklahoma Department of Transportation)Verified Aug 5, 2026

and non-refundable, covering non-divisible loads up to twelve feet wide, fourteen feet high, a hundred and ten feet long and 120,000 pounds gross. Two conditions decide whether it earns that price. It is valid only on the state highway system and only on routes shown green on the current envelope permit map, and it is void on any interstate highway. And exceeding any envelope figure voids it outright, with one narrow mercy: a cumulative overage of a thousand pounds or less voids it for that move only.

What the schedule does not price

A newly manufactured item over sixteen feet but not over twenty-three feet wide carries a special movement fee of $500.00Permit Fees, the Oklahoma Size and Weight Permits fee schedule (Oklahoma Department of Transportation)Verified Aug 5, 2026, which does not apply to houses or manufactured homes. It is the one line on the fee sheet large enough to change a bid on its own, and it is easy to miss because it sits outside the base and weight logic everything else follows.

Oklahoma also declines to define a superload by weight. OAC 730:50-5-4(l) makes a superload any overweight permit load exceeding the Standard Drawing OL-1 trucks, the pre-studied configurations the department has already checked against its overweight truck permit map. There is no gross weight to shop for, which is why no pound figure is recorded for the threshold rather than one being inferred from the neighbors. Where the route has not been studied, every bridge on it gets a structural analysis under the current AASHTO Manual for Bridge Evaluation. Requests go through the automated overload permitting system at least five working days ahead of the movement, more where several bridges are involved, and a Highway Patrol Troop S escort for a super load is arranged by contract through the Size and Weight Permits office, which can take two to four weeks on its own.

Then there are the curfews. Oversize permitted loads may not use the interstate system in Oklahoma, Tulsa or Cleveland counties from 7:00 a.m. to 9:00 a.m. or from 3:30 p.m. to 6:30 p.m., Monday through Friday. Overweight-only loads are exempt from the curfews as well as from the daylight rule, so on a route through Oklahoma City or Tulsa, being heavy rather than wide is the easier schedule.

Reading the schedule like a quote

Ask three questions in order. Is the load over on any dimension? Is it over the legal load limit for the road it will actually run? And does the route touch a county road or the interstate system, either of which moves the answer to the first two? Oversize alone or overweight alone pays one base; both together pays two. Count the thousand pound increments from the ceiling that applies to the road you are on, add the delivery charge if you want the permit emailed, and add four percent if you are paying by card. Everything after that, the escort, the daylight window, the holiday ban and the metro curfews, is schedule rather than fee, and in Oklahoma the schedule is usually the expensive half.

FAQ

How much does an Oklahoma oversize permit cost?

A single trip or monthly permit starts at a minimum fee set by statute, and an overweight load adds ten dollars for each 1,000 pounds it runs over the legal load limit. Distance is not part of the calculation. The current figures render with their sources on the state permits page.

Why does an Oklahoma load that is both oversize and overweight pay two base fees?

Because the permit rules require one permit to cover a load that is both, and price it as though two permits had been issued. The combined base is double the single base, and the per thousand pound weight charge is added on top of it exactly as it would be on an overweight only move.

Does the route change what an Oklahoma overweight permit costs?

Yes, because the legal load limit the overage is measured from changes by road. An overweight permit is required above 80,000 pounds on the interstate system, while off it a vehicle may run to 90,000 pounds gross without one, so the same load has two different overages.

What is Oklahoma's superload threshold?

Oklahoma publishes no gross weight that starts the superload regime. A superload is any overweight permit load exceeding the Standard Drawing OL-1 trucks, the pre-studied configurations the department has already checked against its overweight truck permit map, so the trigger is a drawing rather than a pound figure.
