General requirements
Reducible expectations | A permit is required when a non-divisible vehicle or load which exceeds legal size and/or weight limits is to be moved upon the roads and highways of Oklahoma. A nondivisible load is any load or vehicle exceeding applicable length, width, height, or weight limits which cannot be separated into smaller loads or vehicles without compromising the intent of the load or vehicle. On the Interstate highway system, a vehicle carrying fluid milk products is considered a load that cannot be easily dismantled or divided, or nondivisible. | |||
Permit timing | Requests should be received at least five working days prior to the actual movement of the load. | |||
Method of application | A permit can be applied for and obtained from the Size and Weight Permit Division of the Department of Public Safety, by contacting a permit office either in person, by telephone, from the Department website, or through J. J. Keller & Associates, Inc., Trip Permits, at (800) 231-5266. | |||

Flagpersons
Escort vehicle operators may need to act as flagpersons and direct traffic to stop, slow down, or proceed in situations to allow traffic or the escorted vehicle or load to continue moving safely.
The flagperson must require the escorted vehicle or load to stop, and the escorted vehicle must move as far off of the roadway as possible and stop to allow other traffic to pass, under the following conditions:
- If the escorted vehicle or load becomes disabled;
- When the movement of the escorted vehicle or load on a particular section of roadway presents a safety risk or unreasonable risk to or unreasonably interferes with the efficient movement of other traffic;
- When driving conditions for the escorted vehicle or load are hazardous; or
- When the escorted vehicle or load stops, the escort vehicle operator must direct other traffic past the escorted vehicle or load as necessary until such time as the escorted vehicle or load can reenter the roadway and continue moving without presenting a safety risk or unreasonably interfering with efficient movement of other traffic.
Escort car/company requirements
Escort vehicles must be either a pickup truck of at least one-quarter ton rated load capacity or an automobile weighing at least 2,000 pounds and must be properly licensed. If commercially licensed, an escort for an intrastate move must obtain a temporary registration from the Oklahoma Tax Commission, Motor Vehicle Registration Division.
Escort vehicle operators when performing escort duties must have their drivers license and escort certification on their person and present them for inspection at the request of any law enforcement officer.
The owner of an escort vehicle must display on each side of the escort vehicle the name, city, and state of the escort vehicle company or operator, or the owner of the escort vehicle, or both. The markings must be plainly legible and visible to the motoring public, readily legible during daylight hours from a distance of 50 feet while the vehicle is stationary, kept and maintained in a manner to preserve legibility, and in a color or colors which sharply contrast with the background on which they are placed.
The operator of the escort vehicle cannot perform as a tillerman or steerman while performing escort operations. A tillerman is a person who is physically located on the CMV, has a valid commercial driver license, and who operates by remote control or other means any axle of the CMV. A steerman means a person who is not physically located on the CMV, not required to have a valid commercial driver license, and who operates by remote control or other means any axle of the CMV.
Escort vehicles may not tow any trailer or other vehicles, except that an escort not required to be certified may tow a trailer when escorting a manufactured home. The trailer cannot exceed 8 feet 6 inches in width and 20 feet in length with siding not to exceed 4 feet in height measured from the bed of the trailer. The trailer may only be used to transport supplies and equipment necessary to carry out the mission of escort vehicle operators and cannot be used to carry supplies, cargo, or equipment.
Each certified escort vehicle operator who operates in interstate commerce must maintain a valid insurance policy, and proof of insurance must be carried in the escort vehicles at all times. The insurance policy must protect the public against loss of life, bodily injury, and property damage, and must be at least $1,000,000 combined single limit or $1,000,000 per occurrence, or both, of commercial liability coverage. Coverage must be maintained at all times during the term of the certification. The insurance certificate must indicate on the face of the document that the policy is for the operation of escort vehicles and escort duties and responsibilities.
Escort vehicles must be equipped with the following when escorting an oversize/overweight vehicle or load:
- Red flags at least 12 inches square attached to standards angled upward to the left and right at 45 degree angles and mounted on the top of the cab (no flags may be displayed unless the escort vehicle is actually engaged in escorting);
- Outside rear-view mirror must be on each side of the vehicle;
- Two-way radios capable of transmitting and receiving voice messages over a minimum distance of one mile and compatible with radios in the escorted vehicle and any other escort vehicle(s);

- One AAMVA-approved rotating or flashing amber beacon or a flashing amber light bar system must be mounted on top of the escort vehicle (blue lights are strictly prohibited and red or white rotating lights are not authorized);
- A height measuring pole made of non-conductive, flexible, non-fragile material when escorting a load or vehicle 15 feet 9 inches or more in height;
- Two standard 24-inch STOP and SLOW paddle signs, with reflective surfaces meeting the standards set out in the Manual of Uniform Traffic Control Devices;
- A hard hat and a jacket or vest, both of which meet standards set by the Manual of Uniform Traffic Control Devices, for each person who may be assigned to traffic control, setting reflectors or any other duties conducted on or near a roadway;
- Flashlight equipped with and powered by at least two D-cell batteries; and
- A full-size spare tire for the escort vehicle, tire jack and lug wrench.
Headlights must be lighted at all times during movement. Warning lights may also be used, but warning lights must be removed when not escorting an oversize/overweight movement.
Certification requirements
Pilot/Escort operators must be trained and certified to perform the above duties according to MUTCD (Section 6E.01 Qualifications for Flaggers). To be certified, the person must meet the following requirements:
- Be at least 18 years of age;
- Possess a valid driver license from the state or jurisdiction in which the person is a resident;
- Submit an application for certification to the Size and Weight Permit Division of the Department of Public Safety on the form provided by the Department. The application must contain all required information including a driving record issued within the immediately preceding 30 days; and
- Attend a course in escort vehicle certification, as prescribed by the Department, and successfully pass the escort vehicle certification examination (for more information on courses, contact the Oklahoma Department of Public Safety or visit https://www.ok.gov/dps/).
An escort vehicle operator shall possess an Oklahoma certification, unless the escort vehicle operator is a resident of a state other than Oklahoma which has a reciprocal agreement with Oklahoma recognizing escort vehicle operator certifications issued by that state and is in possession of a current escort vehicle operator certification issued by that state. Under all circumstances, an escort vehicle operator who is an Oklahoma resident must have an Oklahoma certification.
Oklahoma has entered reciprocal compacts and agreements with the following states for the purpose of recognizing escort vehicle operator certifications issued by those states: Colorado, Florida, Georgia, Minnesota, North Carolina, Utah, Virginia, and Washington.
Escort car signs, flags, and lights
