What is legal without a permit?
Axle limits with a permit With a permit- Steer (Annual Envelope)15k lb
- Single (Annual Envelope)20k lb
- Tandem (Annual Envelope)40k lb
- Triple (Annual Envelope)60k lb
- These are the Annual Envelope permit limits. Single-trip overweight permits are set by ODOT's load route review and the OL-1 standard trucks.
- No overweight permit may need a fixed single axle over 20,000 lb or 600 lb per inch of tire tread width, whichever is less.
- Dual-lane superload axles: at least 4 tires and no more than 20,000 lb or 600 lb per inch of tread, whichever is less.
The rule in full5 official sources
General width: 8′6″
Ordinary vehicle-and-load limit; safety-device, vehicle and load exceptions may apply.
Loaded height: 13′6″ / 14′
13′6″ on county roads; 14′ on Interstate, turnpike, U.S. and state highways.
NN semitrailer: 59′6″
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 width is 8′6″. Legal height is 13′6″ on county roads and 14′ on Interstate, turnpike, U.S. and state highways. Length depends on the vehicle setup.
Weight limits
Gross weight alone does not settle it in Oklahoma. Check axle and group spacing, tire limits, Formula B and Table B, registration, route class, bridge maps and postings.
Width
Legal width is 8′6″, with exceptions for some routes, equipment and permits.
Axle limits with a permit
With a permit: steer (annual envelope) 15,000 lb, single (annual envelope) 20,000 lb, tandem (annual envelope) 40,000 lb, triple (annual envelope) 60,000 lb. These are the Annual Envelope permit limits. Single-trip overweight permits are set by ODOT's load route review and the OL-1 standard trucks. No overweight permit may need a fixed single axle over 20,000 lb or 600 lb per inch of tire tread width, whichever is less. Dual-lane superload axles: at least 4 tires and no more than 20,000 lb or 600 lb per inch of tread, whichever is less.

Where Oklahoma’s official sources disagree or say nothing, confirm with the agency before dispatch.
- 47 O.S. § 14-103(B)(1) says the daylight and holiday bans do not apply to vehicles moving under a special permit for greater height issued under that subsection, while ODOT's FAQ says all oversize movement is daylight only. Follow the issued permit.
- ODOT's FAQ says a permit is needed for anything over 13′6″ high, but 47 O.S. § 14-103(B)(1) sets 13½ feet only for county roads and 14 feet for turnpikes, Interstates, U.S. and state highways.
- OAC 730:50-5-6(a)(3) caps oversize permits at 16′ wide on any trip using an Interstate, and 730:50-5-12(d) applies the same 16′ Interstate limit to disaster-area manufactured homes, but 730:50-5-19(d) says manufactured homes over 14′ up to 18′ wide will be permitted on Interstates.
- OAC 730:50-5-16(c)(8) requires a height pole as escort-vehicle equipment for loads 15′9″ or taller without saying which pilot car carries it or how it is set; 730:50-5-18(b)(3) requires a front and a rear pilot car.
- ODOT publishes no general police-escort size trigger. The DPS escort contract form mentions oversize loads over 20 feet but does not say which dimension.
- No two-trigger rule and no overhang escort rule are published.
- No general legal front or rear overhang limit appears in the sources read; ODOT flags loads hanging 4′ or more past the rear.
- No fixed statewide maximum width, length or height for single-trip oversize permits appears in the sources read, apart from the 16′ Interstate width cap; height must clear posted structures by at least 2 inches.
- Single-trip overweight axle and gross limits come from ODOT's OL-1 drawing and load route review; only the Annual Envelope axle limits are stated in the rule text. Legal axle limits (47 O.S. § 14-109) are not repeated in this file.
- The holiday statute does not say whether a holiday that falls on a weekend moves to another day.
- ODOT's rules require the signed original permit or a true and correct facsimile or copy; they do not say whether an electronic copy on a phone or tablet is accepted.
- ODOT's rules say accepting a permit means the permittee meets all operation, registration, license and financial-responsibility requirements, but they name no specific insurance amount, USDOT number or operating-authority filing for carriers.
- ODOT's own Chapter 50 PDF is a marked-up draft showing struck and new text together; this file follows the Chapter 50 text on rules.ok.gov, with sections amended effective 7-13-26.

Which permit do you need?
- ODOT's Size and Weight Permits office runs OkiePROS and publishes current restrictions, axle-weight guides and city and county contacts.
- Start with the carrier and exact route, so the application matches the truck that will move.
SuperloadHeavier than the OL-1 trucks
Any overweight permit load heavier than ODOT's Standard Drawing OL-1 trucks is a superload.

The permit authority
ODOT's Size and Weight Permits office runs OkiePROS and publishes current restrictions, axle-weight guides and city and county contacts. Start with the carrier and exact route, so the application matches the truck that will move.
Roads & authorities
ODOT Size and Weight permits authorize only the identified vehicle/load and approved route; state highways, Interstate/turnpike, county/city, construction, bridge and facility controls must be checked separately.
When a permit is needed
A vehicle/load above the applicable Oklahoma size or weight limit needs the applicable ODOT permit before travel. Single-trip, annual, multi-trip, envelope and special products have different eligibility and durations.
Larger-load review
The Annual Envelope product screen is 12 feet wide, 14 feet high, 110 feet long and 120,000 pounds on green state-highway routes; superloads beyond OL-1 or the envelope need bridge/route review.
Superload
Any overweight permit load heavier than ODOT's Standard Drawing OL-1 trucks is a superload. If the route hasn't been studied for that superload, each bridge on it needs a detailed structural analysis, unless a comparative analysis shows stresses no higher than OL-1. ODOT can also require an evaluation of potential pavement damage on the route. Dual-lane superloads: at most 16′ wide on Interstates and 20′ on the state highway system, clearing posted structures by at least 2″.
Overweight route review
Overweight permit requests go through ODOT's automated system and must arrive at least five working days before the move. More time may be needed when several bridges are involved. OL-1 standard trucks may be permitted on green routes of the Overweight Truck Permit Map; red routes can't carry them.
Interstate and clearance limits
Under ODOT's general oversize rule, a load over 16′ wide can't be permitted on any trip that uses an Interstate, and the load must clear every structure on ODOT's Vertical Clearance of Bridge Structures Map by at least 2 inches.
Special movement permit
Manufactured items over 16′ up to 23′ wide, moving from their point of manufacture, need a $500 special movement permit in addition to the regular permit to use state or U.S. highways. Wider than 23′ only if ODOT finds it in the state's best interest. Does not cover manufactured homes or industrialized housing. Good for one trip; escorts follow ODOT rules.

About the example equipment
The samples use ODPermit’s editable 48 ft flatbed · 5 axles planning profile. Loaded dimensions, gross weight, 100 state miles and Oklahoma registration are example inputs, not a capacity rating or a route approval. Replace them with your actual setup.
Great Dane Freedom flatbed brochure — Drop-deck option: 20–26 in drop from the upper deck with a 40–34 in rear deck height, which gives the 60 in upper-deck planning height. Platform length, combined tare and tractor geometry are editable ODPermit assumptions.

General information only. It is not legal advice and not a permit. ODPermit is operated by Frontline Express LLC, a private company, not a government agency.
We summarize official sources as of the dates shown, but rules change often and a summary can be incomplete or out of date. Only a permit issued by the state or local agency authorizes an oversize or overweight move, and that permit and the agency’s current rules control. Confirm limits, escorts, routes and travel times with the issuing agency before you move a load.

BEFORE THE TRUCK ROLLS
