RouteAllOklahoma Oversize Load Permits: OkiePROS, Escorts, Curfews
Last verified November 3, 2026 against the Oklahoma rules linked below.
An Oklahoma load needs a permit once it is wider than 102 inches, taller than 14 feet on state highways (13 feet 6 inches on county roads) or heavier than 80,000 pounds on an Interstate. The Oklahoma Department of Transportation (ODOT) issues size and weight permits through OkiePROS. A single-trip oversize permit costs $40; overweight adds $10 for every 1,000 pounds over legal.
On This Page
Oversize loads move in daylight only, and Interstates in three metro counties close at weekday rush hours. This page covers that and the rest, each linked to the rule.
What are Oklahoma's legal size limits?
Oklahoma allows 102 inches wide without a permit. Height is 14 feet on turnpikes, Interstates, U.S. and state highways, and 13 feet 6 inches on county roads. Gross weight tops out at 80,000 pounds on an Interstate and 90,000 pounds on other state highways.
The table lists each limit with the source it comes from.
| Dimension | Legal limit | Source |
|---|---|---|
| Width | 102 inches, tire bulge and safety devices excluded | 47 O.S. §14-103(A) |
| Height | 14 feet on turnpikes, Interstates, U.S. and state highways; 13 feet 6 inches on county roads | §14-103(B) |
| Single truck | 45 feet | §14-103(C)1 |
| Semitrailer | 53 feet | §14-103(C)3 |
| Axle weight | 20,000 pounds single; 34,000 tandem | §14-109 |
| Gross weight | 80,000 pounds on Interstates; 90,000 on other state highways | OAC 730:50-5-4(b), §14-101(E) |
The widest load Oklahoma permits on an Interstate is 16 feet (OAC 730:50-5-6(a)(3)). ODOT's own permit FAQ says a permit is needed over 13 feet 6 inches high, so treat that as the line whenever the route touches a county road.
How do you get an Oklahoma oversize permit?
Order it in OkiePROS, the Oklahoma Department of Transportation's (ODOT) online size and weight permitting system, also called Permit Manager. Before the first order, ODOT needs a New Company Profile form and a copy of the applicant's driver's license. The Oklahoma City permit office answers at 405-425-7012 (ODOT Size and Weight Permits).
The application names the owner, the truck and every trailer by make and plate, and the load. For oversize it lists all oversize dimensions and the front and rear overhang. For overweight it adds gross weight, axles, spacings and axle weights (OAC 730:50-5-3(4)).
Oklahoma applies no permit tolerances (730:50-5-3(5)). A vehicle on out-of-state plates cannot take an intrastate permit unless its registration is prorated or temporarily licensed in Oklahoma ((1)). A load is non-divisible only if splitting it ruins its use or value, or takes more than 8 work hours ((2)(A)).
| Permit | Fee | Source |
|---|---|---|
| Single-trip or monthly oversize | $40 | ODOT fees |
| Single-trip overweight | $40 plus $10 per 1,000 pounds over legal | ODOT fees, §14-116(A) |
| Oversize and overweight | $80 plus $10 per 1,000 pounds over legal | ODOT fees |
| Multi-trip | $40 a month, $480 at most for 12 months | ODOT fees |
| Special movement, new manufactured items over 16 to 23 feet wide | $500 | ODOT fees |
| Annual envelope | $4,000 | ODOT fees, 730:50-5-13 |
| Permit sent by fax or email | $2 | ODOT fees |
Card payments carry a 4% convenience fee (ODOT fees). Each permit gets one revision at most, and the load description and dimensions cannot be changed (OAC 730:50-5-1(7)). For bad weather, road conditions or a breakdown, you can suspend a permit once, for up to two weeks, by calling the permit office within the trip dates (730:50-5-2).
An annual envelope permit covers up to 12 feet wide, 14 feet high, 110 feet long and 120,000 pounds. It runs only on the "green" routes of ODOT's envelope map, never on an Interstate, and breaking the metro curfews voids it (OAC 730:50-5-13). The choice is covered in annual vs single-trip oversize permits, and reading the result in how to read an Oklahoma oversize permit.
RouteAll reads the permit you upload and keeps you on the roads it names. It never reroutes you off them; ODOT can invalidate a permit for not following its routes of travel (730:50-5-3(9)).
What are Oklahoma's bridge and clearance rules?
A permitted load must clear every overhead structure on ODOT's Vertical Clearance of Bridge Structures Map by at least 2 inches. It must make every turn without using shoulders or leaving the travel lanes and ramps (OAC 730:50-5-6(a)). Overweight requests go to ODOT at least five working days before the move, longer when many bridges are involved (730:50-5-4(j)).
"No permit tolerances shall apply to any permitted vehicle and/or load." — OAC 730:50-5-3(5). Verified November 3, 2026.
- Overweight Truck Permit Map: ODOT's standard OL-1 trucks may use routes shown green. Routes shown red cannot carry them (730:50-5-4(i)-(j)).
- Bridge reviews: ODOT's Bridge and Maintenance Divisions check each route to the AASHTO Manual for Bridge Evaluation, and may lower the allowed stress on a deteriorated bridge (730:50-5-4(h)).
- Lane position: keep right of center, except on a bridge where the permit says to run the centerline (730:50-5-3(7)).
- Construction: ODOT publishes a current Restriction List. City streets and county roads may need the local authority's permission too (municipal and county contacts).
Read what happens if you leave your permitted route before you plan a detour around a closure.
When does Oklahoma require a pilot car?
Oklahoma requires one escort over 12 feet wide, in front on two-lane highways and behind on multi-lane highways. Over 14 feet wide, two-lane roads need front and rear; over 16 feet, every road does. At 15 feet 9 inches high or more, front and rear escorts and a height pole are required.
| Load | Escorts | Source |
|---|---|---|
| Over 12 to 14 feet wide | One; front on two-lane and super two-lane, rear on multi-lane | (b)(1) |
| Over 14 feet wide | Front and rear on two-lane and super two-lane; rear on multi-lane | (b)(2) |
| Over 16 feet wide | Front and rear on all roads | (b)(2) |
| 15 feet 9 inches high or more | Front and rear, with a height pole; call utilities and railroads ahead | (b)(3) |
| Tractor-semitrailer over 80 feet long | One in front on two-lane highways | (b)(4) |
| Any combination over 100 feet long | Front and rear on two-lane and super two-lane | (b)(5) |
Anyone escorting for hire must hold ODOT certification: at least 18, the Oklahoma State University course and 75% on the exam, renewed every five years (730:50-5-17). Each escort carries a roof-mounted amber beacon visible at 500 feet, a two-way radio good for 1 mile and $1,000,000 of liability cover (730:50-5-16). Escorted loads may not travel in convoy (730:50-5-3(8)). Credentials and reciprocity are in Oklahoma pilot car qualifications; other states in pilot car requirements by state.
When can an oversize load move in Oklahoma?
An oversize load moves in daylight only, half an hour before sunrise to half an hour after sunset, unless ODOT endorses the permit for night travel. A load permitted only for overweight may move around the clock (47 O.S. §14-101(F)).
- Metro curfews: no oversize loads on Interstates in Oklahoma, Tulsa or Cleveland County from 7 to 9 a.m. and 3:30 to 6:30 p.m., Monday through Friday. I-35 between SH-9 East (Exit 108) and SH-9 West (Exit 106) is exempt (OAC 730:50-5-1(1)). ODOT gives the times in Central Time (ODOT FAQ).
- Curfew exemptions: overweight-only loads, longer combination vehicles and special combination vehicles (730:50-5-1(3)).
- Holidays: no movement at any time on New Year's Day, Memorial Day, the Fourth of July, Labor Day, Thanksgiving Day or Christmas Day. Martin Luther King Jr. Day, Presidents' Day and Veterans Day stay open (§14-101(G)).
- Weather: stop when snow, ice, sleet, fog, dust, smoke or wind make the move unsafe, and resume only when it is reasonably safe (730:50-5-1(4)).
- Weekends: Section 14-101 and Rule 730:50-5-1 list no weekend ban. Houses and buildings never move on Saturday or Sunday (730:50-5-21(2)).
Every state's windows are side by side in oversize load travel restrictions by state.
What signs, flags and lights does Oklahoma require?
Every oversize load carries an OVERSIZE LOAD sign on the front of the towing vehicle and on the rear of whatever extends farthest. Each is at least 5 feet by 14 inches, with 8-inch black letters of 1 1/8-inch stroke on yellow, and is never shown at legal size (OAC 730:50-5-15(a)).
Flags are solid red or fluorescent orange, at least 18 inches square, on the corners and widest points of overwidth and overlength loads. A rear overhang of 4 feet or more takes one flag if it is 2 feet wide or less, and two if wider (730:50-5-15(b)). Escort signs may be 10 inches high (730:50-5-16(c)). Details are in Oklahoma oversize load signs, flags and lights, and other states in sign requirements by state.
What is a superload in Oklahoma?
ODOT defines a superload as an overweight load heavier than its standard OL-1 trucks. On a route not studied before, every bridge gets a detailed structural analysis (OAC 730:50-5-4(l)). Dual-lane superloads may be up to 16 feet wide on an Interstate and 20 feet on other state highways (730:50-5-4(m)).
At 15 feet 9 inches high or more, file ODOT's Contact List for Utilities and Railroads. A newly manufactured item over 16 feet wide needs the Special Movement Application, and loads that may need a Highway Patrol escort file the OHP Escort Contract (ODOT forms).
Use This Check In RouteAll
After OkiePROS issues the permit, use RouteAll’s permit-to-GPS workflow to compare its highway sequence with a reviewable map. Keep curfews, holiday dates and escort instructions available separately. RouteAll does not issue permits or amend the authorized roads.
Before you roll
Plan a daylight move, and time it to clear Interstates in Oklahoma, Tulsa and Cleveland counties outside the weekday rush windows. Over 12 feet wide, book a certified escort; at 15 feet 9 inches high, two escorts and a height pole. Check the current Restriction List the morning you leave. For a stop such as TA Sayre at I-40 Exit 26, see the Oklahoma truck stop guide and check the approach against your permit.
Common questions
How much is an Oklahoma oversize permit?
A single-trip oversize permit costs $40 on ODOT's fee schedule, the minimum 47 O.S. 14-116 sets. Overweight adds $10 for each 1,000 pounds over the legal limit, and a load that is both oversize and overweight starts at $80. An annual envelope permit costs $4,000.
Can oversize loads travel at night in Oklahoma?
Only if ODOT endorses the permit for it. Section 14-101(F) limits permitted vehicles to daylight, half an hour before sunrise to half an hour after sunset. Loads permitted only for overweight are exempt and may run around the clock.
What are the Oklahoma City and Tulsa oversize curfews?
Oversize loads may not use Interstates in Oklahoma, Tulsa or Cleveland County from 7 to 9 a.m. or 3:30 to 6:30 p.m., Monday through Friday, under OAC 730:50-5-1. Interstate 35 between Exits 106 and 108 in Cleveland County is exempt, and so are overweight-only loads.
When does Oklahoma require a pilot car?
Over 12 feet wide, one escort: in front on two-lane highways, behind on multi-lane highways. Over 14 feet, front and rear on two-lane highways; over 16 feet, front and rear on all roads. At 15 feet 9 inches high or more, front and rear with a height pole.
Which holidays stop oversize loads in Oklahoma?
New Year's Day, Memorial Day, the Fourth of July, Labor Day, Thanksgiving Day and Christmas Day, under 47 O.S. 14-101(G). Permitted loads may move on Martin Luther King Jr. Day, Presidents' Day and Veterans Day.
Do Oklahoma pilot car drivers need a certification?
Yes, anyone escorting for hire. OAC 730:50-5-17 requires ODOT certification: at least 18, a valid license, the state course and 75% on the exam, renewed every five years. A nonresident may use a home-state certification if that state has reciprocity with Oklahoma.
