By Evan Reid, Founder of Haul Handbook · Updated Aug 5, 2026
Oversize and overweight permits are the one Oklahoma trucking credential the Corporation Commission does not issue. The Department of Transportation Size and Weight Permits office sells them through OkiePROS, its online permit manager, starting at a $40 minimum fee with $10 added for every 1,000 pounds over the legal load limit. Legal limits are 8 feet 6 inches wide, 14 feet high on a turnpike, interstate, US or state highway and 13 feet 6 inches on a county road, and a federal bridge formula gross weight capped at 80,000 pounds on the interstate system and 90,000 pounds off it. Escorts start at 12 feet wide, and oversize movement is daylight only and banned outright on six holidays.
Who issues what in Oklahoma
The permit pages
Oklahoma-specific requirements
Oklahoma puts almost the whole trucking compliance stack behind one counter. The Corporation Commission's Transportation Division issues intrastate for-hire and private motor carrier licences, household goods certificates, USDOT numbers, IRP apportioned plates, IFTA licences, UCR registration, harvest permits, deleterious substance permits, and the 72-hour trip and 120-hour fuel permits. The only major credential it does not touch is the oversize or overweight permit, which the Department of Transportation sells through OkiePROS. Oklahoma issues no branded carrier number; what it issues instead is a $7.00 identification device, one per power unit, bought again every year.
One agency for everything except oversize permits
The Corporation Commission's Transportation Division administers intrastate motor carrier licences, household goods certificates, USDOT number issuance, IRP, IFTA, UCR, harvest permits, deleterious substance permits, trip and fuel permits, transportation network company permits and nonconsensual towing rates. Oversize and overweight permits are the exception: since Senate Bill 638 took effect on November 1, 2015 they are issued by the Department of Transportation Size and Weight Permits office, and the Commission's own forms page redirects carriers there.
No state carrier number, a $7 stamp instead
Oklahoma issues nothing like a CA number or TxDMV number. The Commission assigns a personal identification number to the application file and sells a physical identification device, a stamp, for $7.00 per power unit. The carrier keeps the original licence on file, copies it, puts one stamp on each copy, and carries a stamped copy in every truck. Devices expire with the licence, cannot be sold or transferred except onto a substitute vehicle, and are re-bought every year even when the licence itself was renewed for two or three.
For-hire authority has no weight floor
The 26,000 pound figure carriers hear about Oklahoma is the private carrier trigger, not the for-hire one. OAC 165:30-3-1(a) bars any intrastate motor carrier from hauling passengers or property for hire on an Oklahoma road without a licence, with no weight figure anywhere in the rule. A one-truck for-hire operation running a 16,000 pound straight truck inside the state still needs the licence and still files insurance.
Licence renewable for up to three years, stamps only for one
47 O.S. Section 230.27(B) allows an intrastate licence to be renewed for up to three years at $50 a year, and the Commission's private carrier page says the same. The identification devices never stretch that far: a stamp has to be bought for every vehicle every year, and the Commission notes that stamp renewal takes less paperwork than a licence renewal.
No temporary intrastate authority exists
There is no way to start hauling intrastate in Oklahoma while an application is pending. The Commission states plainly that there is no temporary authority for intrastate motor carrier purposes and that a carrier must hold the proper authority before engaging in intrastate operations. OAC 165:30-3-1(a)(4) reinforces it: filing an application does not of itself authorise any operations, and every requirement must be met within 30 days of receipt or the application is dismissed.
Deleterious Substance Transport Permit at 20 gallons
A carrier moving deleterious substances in any quantity over 20 gallons, in intrastate or interstate commerce, must hold a Deleterious Substance Transport Permit on top of its intrastate authority or UCR registration. It costs $350 a year, is renewed annually, and the applicant has to show proof of access to a licensed disposal site. Storing deleterious substances in a truck yard wash pit needs a separate Truck Yard Wash Pit Permit, and soil farming of drilling fluids needs a permit from the Commission's Oil and Gas Division.
Harvest Permit is three credentials in one
Anyone hauling farm products in a raw state commercially who lacks commercial vehicle registration, an intrastate motor carrier licence or a fuel permit can buy a Harvest Permit instead of all three. 47 O.S. Section 230.34a says the permit is recognised in lieu of registration, fuel permit and intrastate operating authority. It runs 30 days at $20 per axle or 60 days at $35 per axle, extends in 15-day increments at $8.75 per axle, needs $350,000 combined single limit liability per vehicle, and is applied for on Form TOSS 1.
5 percent gross and 8 percent axle weight variance for raw commodities
Oklahoma sells a $350 annual special overload permit that lets a vehicle registered at the maximum allowable rate run 5 percent over the bridge formula gross limit and 8 percent over the axle limits when hauling roll-off recycle metals, rock, sand, gravel, coal, flour, timber, pulpwood, chips in their natural state, oil field fluids or drilling equipment, grain, fertilizer, cottonseed, cotton, livestock, peanuts, canola, sunflowers, soybeans, feed and other raw or unprocessed agricultural products. No component may exceed the manufacturer's rating and the vehicle is barred from the interstate system. The same 2015 law moved Oklahoma onto the federal bridge chart. The ODOT axle chart prints the variance figures beside the legal ones, and a single axle under the permit may reach 21,600 pounds.
Fourteen foot legal height on the state system, thirteen six on county roads
47 O.S. Section 14-103(B)(1) allows 14 feet on any turnpike, interstate, US or state highway but only 13 feet 6 inches on a county road, so the same load can be legal on the highway and oversize on the last mile. The Size and Weight Permits FAQ answers the permit question at the lower figure. An operator over 13 feet 6 inches is liable for damage to any structure spanning the highway regardless.
Six holidays banned, three expressly allowed
47 O.S. Section 14-101(G) bans permitted movement outright on New Year's Day, Memorial Day, Independence Day, Labor Day, Thanksgiving Day and Christmas Day, and then does something most states do not: it expressly allows permitted movement on Martin Luther King Jr's Birthday, Presidents Day and Veterans Day. Oversize movement is otherwise daylight only, one half hour before sunrise to one half hour after sunset, while an overweight-only load has continuous travel.
Metro curfews in three counties only
Oversize permitted loads may not use the interstate system in Oklahoma County, Tulsa County or Cleveland County from 7:00 to 9:00 a.m. or 3:30 to 6:30 p.m., Monday through Friday. The rule carves out a two mile stretch of Interstate 35 in Cleveland County between State Highway 9 East at Exit 108 and State Highway 9 West at Exit 106. Special combination vehicles, longer combination vehicles and overweight-only loads are exempt, and violating a curfew voids an Annual Envelope Vehicle Permit.
A superload is defined by a drawing, not a weight
Oklahoma sets no pound figure for a superload. OAC 730:50-5-4(l) defines it as any overweight permit load that exceeds the Standard Drawing OL-1 trucks, the standard configurations ODOT has already studied against its Overweight Truck Permit Map. If the route has not been studied for the proposed load, every bridge on it gets a detailed structural analysis under the current AASHTO Manual for Bridge Evaluation. Overweight permit requests need at least five working days, more where several bridges are involved, and an Oklahoma Highway Patrol Troop S escort contract can add two to four weeks.
Escorts start at 12 feet wide, and escort operators for hire must be state certified
47 O.S. Section 14-120.1 requires an escort for anything wider than 12 feet on any Oklahoma highway including the interstate, and bars anyone from operating an escort vehicle for hire without Department of Transportation certification. Certified operators carry at least $1,000,000 combined single limit commercial liability coverage with proof in the vehicle, and the equipment list in OAC 730:50-5-16 is long: amber beacon, two-way radio, fire extinguishers, STOP and SLOW paddles, hard hat and vest, flashlight, full-size spare, and a non-conductive height pole once the load reaches 15 feet 9 inches. Retail implement dealers moving farm implements within 150 air miles of the distribution point are exempt from the escort requirement.
Oklahoma left the Alliance for Uniform Hazardous Materials Program
Effective July 1, 2025 the Corporation Commission withdrew from the Alliance for Uniform Hazardous Materials Program. A carrier that only transports hazardous waste through Oklahoma no longer needs an Alliance permit for that movement, but still needs a valid PHMSA hazmat registration number and an EPA identification number issued by the Oklahoma Department of Environmental Quality. Carriers running hazardous waste or materials through Michigan, West Virginia or Nevada still need an Alliance permit for those states.
Paper filing is priced out for larger fleets
The Commission charges a fleet of more than 25 vehicles $100 to file an IFTA application on paper and $25 per vehicle to file an apportioned registration application on paper, and waives both entirely for electronic filing. It also charges $100 per apportioned vehicle as a registration services fee and $100 to reprocess an application spoiled by Commission error or applicant misrepresentation.
A company profile is a prerequisite to buying a size and weight permit
Before ordering any Oklahoma oversize or overweight permit, a company profile has to be on file with the Size and Weight Permits office, submitted with a copy of the driver licence of the person filing it. Permits are then bought through OkiePROS, with a $2 charge for a faxed or emailed permit and a 4 percent convenience fee on credit card payments.
No weight-distance tax
Oklahoma levies no weight-distance, weight-mile or highway use tax on motor carriers. Fuel tax reaches the state through IFTA and the highways through registration and permit fees instead. Recorded here as a sourced negative so a carrier comparing Oklahoma with Kentucky, New Mexico, New York or Oregon can see the difference is real and not a gap in the research.
More Oklahoma rules that catch carriers out
- ELD intrastate adoption: regulation
- OAC 595:35-1-4, read with 47 O.S. Section 230.15 and 47 O.S. Section 14-125
- ELD intrastate adoption: current text amendment
- Oklahoma Register Volume 39, Issue 24, September 1, 2022, effective September 11, 2022
- ELD intrastate adoption: summary: text
- Oklahoma runs intrastate motor carrier safety out of the Department of Public Safety, which adopts 49 CFR Part 395 by reference at OAC 595:35-1-4. The electronic logging device requirement in 49 CFR 395.8 therefore reaches an Oklahoma intrastate driver on the same terms it reaches an interstate one. Two Oklahoma statutes change what that device is recording. 47 O.S. Section 14-125 exempts agricultural motor vehicles engaged in intrastate commerce from the electronic logging device and hours of service requirement outright, which is an ELD-specific exemption written into statute rather than an hours-of-service carve-out. 47 O.S. Section 230.15 caps intrastate driving at 12 hours within a work period against the federal 11, bars driving hours and on-duty status from beginning after less than 8 consecutive hours off duty, and forbids the Department from adopting any rule that enforces the federal 30-minute rest break against a driver or carrier engaged solely in intrastate commerce.
- ELD intrastate adoption: adopted parts: value
- The Department of Public Safety adopts by reference the United States Department of Transportation regulations pertaining to motor carrier safety and hazardous materials transportation, as contained in Title 49 of the Code of Federal Regulations, and makes each adopted part enforceable pursuant to 47 O.S. Section 230.4(2). The list is Parts 40, 107, 171, 172, 173, 177, 178, 180, 382, 383 (in so much as it does not conflict with state law), 385, 386, 380, 390, 391, 392, 393, 395, 396 and 397. Part 395, Hours of Service of Drivers, is on the list, and the list carries no carve-out for subpart B, the electronic logging device specifications.
- ELD intrastate adoption: record of duty status: value
- Because Part 395 is adopted whole and the chapter's deletions section never touches it, 49 CFR 395.8 applies to an Oklahoma intrastate driver as written. Paragraph (a)(1)(i) requires a motor carrier operating commercial motor vehicles to install and require each of its drivers to use an electronic logging device to record duty status in accordance with subpart B of part 395, no later than December 18, 2017. The four manual record-of-duty-status cases in paragraph (a)(1)(ii) are federal, not Oklahoma exceptions, and Oklahoma adds none of its own inside the rule chapter.
- ELD intrastate adoption: agricultural ELD exemption: value
- Agricultural motor vehicles engaged in intrastate commerce shall be exempt from the requirement for electronic logging devices and hours of services as mandated by Section 32301(b) of the U.S. Commercial Motor Vehicle Safety Enhancement Act. For the purposes of this section, agricultural vehicles shall include, but are not limited to, single axel trucks with a gooseneck or bumper pull trailer for the purpose of hauling horses or livestock, and trailers with living quarters.
- ELD intrastate adoption: hours of service variance: regulation
- 47 O.S. Section 230.15(D), directing the Department of Public Safety's rules under OAC Title 595 Chapter 35
- ELD intrastate adoption: unmodified sections: value
- The chapter's deletions, substitutions and additions section is short, applies only to intrastate commerce, and covers four things: terminology substitutions for the federal agency names, Unified Registration System filing and USDOT number display for every intrastate motor carrier, an 18-year-old minimum driving age in solely intrastate commerce, and who may declare an emergency and how the hours are accounted for afterwards. It contains no hours-of-service modification, no rest-break deletion and no change to 49 CFR 395.8. Everything else in the adopted parts runs at its federal text.
- ELD intrastate adoption: driver age: value
- A driver in solely intrastate commerce must be at least eighteen (18) years old, and at least twenty-one (21) years old to transport hazardous materials requiring placarding or marking under 49 CFR 177.823, or to transport more than eight passengers for compensation or more than fifteen passengers not for compensation.
- ELD intrastate adoption: applicability: value
- Which intrastate vehicles the adopted federal safety rules reach is set by OAC 595:35-1-5(b), and the published versions of that subsection disagree. The Legal Information Institute publishes a version labelled effective until September 14, 2025 that reaches intrastate vehicles in excess of 26,000 pounds gross vehicle weight or gross combination weight, and a version labelled effective September 14, 2025 that opens 'Except as provided by 47 O.S. Section 230.15' and reaches intrastate vehicles at a weight rating or weight of ten thousand one (10,001) pounds or more, whichever is greater. Both versions also reach vehicles designed to carry more than 8 passengers for compensation, more than 15 passengers not for compensation, and placarded hazardous materials.
- ELD intrastate adoption: agricultural season: value
- The federal agricultural exception in 49 CFR 395.1(k) switches off part 395 during planting and harvesting periods as determined by each state, for the four listed hauls inside a 150 air-mile radius. The Department of Public Safety publishes Oklahoma's determination as January 1 to December 31, so the federal agricultural relief runs the whole year here.
- ELD intrastate adoption: short haul reference: value
- 49 CFR 395.1(e)(1) is adopted unmodified, so the 150 air-mile short-haul exception releases an Oklahoma intrastate driver from 49 CFR 395.8 and 395.11 on the federal terms: inside 150 air miles of the normal work reporting location, returned and released within 14 consecutive hours, with 10 consecutive hours off separating each 14 hours on duty, and 6 months of time records kept by the carrier.
- ELD intrastate adoption: commerce test: value
- The variance and the exemption are both written for intrastate commerce, and the Department of Public Safety applies the federal definitions in 49 CFR 390.5 and the interpretations at 49 CFR 390.3 to decide which one a load is on. Troop S publishes seven Oklahoma worked examples, including a delivery truck that never leaves Norman running interstate because one appliance on it shipped from a Texas distribution center to that customer.
- ELD intrastate adoption: federal rule suspension lever: value
- The Department of Public Safety may promulgate rules suspending the effective date of any new United States Department of Transportation motor carrier safety regulation for up to three years as applied to vehicles engaged solely in intrastate commerce, provided the suspension does not cost Oklahoma its federal Motor Carrier Safety Assistance Program funding.
- ELD intrastate adoption: notes
- Authored 2026-08-05 by reading 47 O.S. Sections 14-125 and 230.15 in full at OSCN and OAC 595:35-1-4, 595:35-1-5 and 595:35-1-6 in full at two republishers of the Oklahoma Administrative Code. Two facts the plan left open were resolved this pass. First, 47 O.S. Section 230.15 is OSCN CiteID 438772 and its real catchline is 'Violations by Motor Carrier - Liability and Property Damage Insurance - Limitations on Driving Hours', not the longer heading other publishers print. Second, OAC 595:35-1-6 does NOT remove the 49 CFR 395.3(a)(3)(ii) rest break; the deletions section carries no hours-of-service content at all, and the bar is statutory at 47 O.S. Section 230.15(D)(2). One correction to the plan's paraphrase is recorded above: the emergency relief in 230.15(D)(1) is not a general suspension of hours during any declared emergency, it is limited to rural electric cooperatives, public utilities, public service corporations and municipal employees performing emergency restoration service. The rules.ok.gov code-search interface refuses automated requests, so the administrative text used on 2026-08-05 was the Legal Information Institute's republication cross-checked against a second republisher. On 2026-08-06 the cross-check was redone against the official complete export of OAC Title 595 that the rules.ok.gov portal itself serves, because the second republisher's host stopped answering; OAC 595:35-1-6 matches the text recorded here word for word, including its catchline. That re-read does not settle the OAC 595:35-1-5(b) applicability conflict recorded above, so no single threshold is asserted.
ELD intrastate adoption: hours of service variance: items
| Name | Intrastate | Federal interstate | Regulation |
|---|---|---|---|
| Driving time | The maximum driving time within a work period is twelve (12) hours if the vehicle is engaged solely in intrastate commerce and is not transporting hazardous materials as defined by the federal regulations. | A driver may drive a total of 11 hours during the 14-hour period. | 47 O.S. Section 230.15(D)(1), against 49 CFR 395.3(a)(3)(i) |
| 30-minute rest break | No rule shall be adopted that enforces the provisions of 49 CFR Section 395.3(a)(3)(ii) relating to rest breaks, if the driver or motor carrier is engaged solely in intrastate commerce. | Driving is not permitted if more than 8 hours of driving time have passed without at least a consecutive 30-minute interruption in driving status. | 47 O.S. Section 230.15(D)(2), against 49 CFR 395.3(a)(3)(ii) |
| Off duty before driving | Driving hours and on-duty status shall not begin following less than eight (8) consecutive hours off duty. | A driver may not drive without first taking 10 consecutive hours off duty. | 47 O.S. Section 230.15(D), against 49 CFR 395.3(a)(1) |
| Emergency restoration relief | In the event of an emergency, and on notification of the nearest Oklahoma Highway Patrol troop headquarters, the Commissioner or a designated agent shall declare an emergency and there shall be no hour restrictions for rural electric cooperatives, public utilities, public service corporations or municipal employees while the emergency lasts, for service restoring heat, light, power, water, telephone or other emergency restoration facilities necessary to the health, welfare and safety of the public. | Federal relief from part 395 during an emergency runs through 49 CFR 390.23 rather than a state declaration. | 47 O.S. Section 230.15(D)(1) |
The permit office and OkiePROS
The Size and Weight Permits office sits inside the Department of Transportation, with a headquarters counter in Oklahoma City and field locations in Tulsa, Elk City and Enid. Permits are ordered through OkiePROS, and there is a step before the first order: a company profile has to be on file, submitted with a copy of the filing person's driver license.
Charges stack on top of the permit itself. The Department adds a fee for a permit delivered by fax or email, and a percentage convenience fee on credit card payments. Both are sourced fields on the Oklahoma oversize and overweight page.
The permit types Oklahoma issues
Single-trip and monthly permits cover a load over the legal limits, priced from a minimum permit fee with an added charge for every thousand pounds above the legal load limit. A load that is both oversize and overweight is charged as though two permits had been issued.
Annual permits run from cheap to expensive. At the top is the Annual Envelope Vehicle Permit, a year of moves inside a published dimension and weight envelope, valid only on state highway routes shown green on the current permit map and void on any interstate. Below it Oklahoma sells more than a dozen cheaper annuals: special purpose permits for construction equipment and mobilized machinery, longer combination and triples permits, an empty overwidth trailer permit, agriculture permits for round baled hay, tree length logs and soil conservation equipment, and weight variance permits for wreckers, utility and refuse vehicles, and raw commodity hauling.
Our Oklahoma oversize and overweight page carries the full fee schedules, escort thresholds and the superload review.
The permits the Corporation Commission sells
Short-term credentials are the Commission's, not the Department's. A commercial vehicle registration trip permit registers an unregistered truck or trailer in Oklahoma for a few days. A fuel permit satisfies the motor fuel use tax obligation for a set period instead of an IFTA license. An unladen permit buys weeks to move an empty truck after a lease breaks and the carrier keeps the plate and cab card. All three are bought from the same online application or from a contracted wire service, all three can be dated ahead of purchase, and none of them is refundable.
Two more sit alongside. The harvest permit is the Commission's all-in-one seasonal credential for hauling raw farm products, recognized in place of registration, fuel permit and intrastate authority together. The deleterious substance permit is required annually on top of intrastate authority for anyone moving those substances above a published quantity, and the applicant has to show access to a licensed disposal site.
Curfews, holidays and daylight
Oklahoma restricts permitted movement three ways. Oversize permitted loads move in daylight only, from a half hour before sunrise to a half hour after sunset, and the Department's Executive Director can endorse a permit for night travel for good cause. Overweight-only loads travel continuously.
Six holidays close the road to permitted movement outright, and the statute then does something most states do not: it expressly allows permitted movement on three more. Metro curfews cover the interstate system in three counties on weekday mornings and afternoons, with one short stretch of interstate carved out, and violating a curfew voids an Annual Envelope Vehicle Permit. On top of all that the Department publishes a dated restriction list of every current route restriction, updated continuously, which permittees are expected to check before traveling.

Frequently asked questions
Where do I apply for Oklahoma truck permits?
- Oversize and overweight permits go through OkiePROS, the Department of Transportation permit manager, after a company profile is on file. Trip, fuel, unladen and harvest permits come from the Corporation Commission's online application instead.
Does Oklahoma offer an annual oversize permit?
- Yes, several. The Annual Envelope Vehicle Permit is the broad one, covering a year of moves inside a published dimension and weight envelope on approved state highway routes. More than a dozen cheaper annual permits cover farm, forestry, construction, utility and longer combination work.
Are there commodity-specific permits in Oklahoma?
- Yes. Oklahoma issues annual permits for round baled hay, tree length logs and soil conservation equipment, plus a weight variance permit for raw and unprocessed commodities such as rock, sand, gravel, timber, grain, livestock and oil field fluids. Most of them bar interstate travel.
When can permitted loads not move in Oklahoma?
- Oversize permitted loads move in daylight hours only, and six named holidays stop permitted movement altogether. Interstate curfews close weekday rush windows in three counties. Overweight-only loads are exempt from the daylight rule and the curfews.
