The Commissioner and each officer of the Department of Public Safety as shall be designated and all members of the Oklahoma Highway Patrol Division shall have the following powers and duties:
2. The officers and members of the Oklahoma Highway Patrol Division are hereby declared to be peace officers of the State of Oklahoma and shall be so deemed and taken in all courts having jurisdiction of offenses against the laws of the state. The members of the Oklahoma Highway Patrol Division shall have the powers now or hereafter vested by law in peace officers except the serving or execution of civil process. The members of the Oklahoma Highway Patrol Division shall have authority to arrest without writ, rule, order or process any person detected by them in the act of violating any law of the state. When a member of the Oklahoma Highway Patrol Division is in pursuit of a violator or suspected violator and is unable to arrest such violator or suspected violator within the limits of the district or territory over which the jurisdiction of such member of the Oklahoma Highway Patrol Division extends, the officer shall be and is hereby authorized to continue in pursuit of such violator or suspected violator into whatever part of the state may be reasonably necessary to effect the apprehension and arrest of the same, and to arrest such violator or suspected violator wherever he or she may be overtaken, and to assist in the location of stolen property, including livestock and poultry or the carcasses thereof, and to make any inspection necessary of any truck, trailer or contents thereof in connection therewith.

The Commissioner may designate any portion of the National System of Interstate and Defense Highways, and those portions of the federal-aid primary highways and the state highway system which are located on the outskirts and are within the boundaries of any municipality, as hereinbefore defined for special traffic-related enforcement by the Oklahoma Highway Patrol Division and issue a written notice to any other law enforcement agency affected thereby. Upon receipt of such notice, the affected law enforcement agency shall not regulate traffic nor enforce traffic-related statutes or ordinances upon such designated portion of the National System of Interstate and Defense Highways or such designated portions of the federal-aid primary highways and the state highway system without prior coordination and written approval of the Commissioner. Nothing in this section shall limit a member of the Oklahoma Highway Patrol Division from requesting assistance from any other law enforcement agency nor limit officers of such agency from rendering the requested assistance. The officer and the law enforcement agency responding to the request of the member of the Oklahoma Highway Patrol Division or sheriff's department shall have the same rights and immunities as are possessed by the Oklahoma Highway Patrol Division.
The powers and duties conferred on the members and officers of the Oklahoma Highway Patrol Division shall not limit the powers and duties of sheriffs or other peace officers of the state or any political subdivision of the state; provided, however, that the Oklahoma Highway Patrol Division shall have primary law enforcement authority respecting traffic-related offenses upon the National System of Interstate and Defense Highways, and may have special law enforcement authority on those portions of the federal-aid primary highways and the state highway system which are located on the outskirts and are within the boundaries of any municipality, and designated by the Commissioner of Public Safety for such special law enforcement authority. The outskirts of a municipality may be determined by reference to the following factors:
10. It shall be the duty of the Oklahoma Highway Patrol Division to enforce the laws of the state relating to the registration and licensing of motor vehicles; to enforce the laws relating to the operation and use of vehicles on the highway; to enforce and prevent, on the roads of the state highway system, the violation of the laws relating to the size, weight, and speed of commercial motor vehicles and all laws designed for the protection of the highway pavements and structures on such highways; to investigate and report to the Corporation Commission and the Oklahoma Tax Commission violation of their rules and regulations and the laws governing the transportation of persons and property by motor transportation companies and all other motor carriers for hire; to investigate and report violations of all laws relating to the collection of excise taxes on motor vehicle fuels; and regulate the movement of traffic on the roads of the state highway system. It shall be the duty of the Oklahoma Highway Patrol Division, whenever possible, to determine persons causing or responsible for the breaking, damaging, or destruction of any improved surfaced roadway, structure, sign, marker, guardrail, or any other appurtenance constructed or maintained by the Department of Transportation, and to arrest persons responsible therefor and to bring them before the proper officials for prosecution. It shall be the duty of the Oklahoma Highway Patrol Division to investigate and report all motor vehicle accidents on the state highway system outside of incorporated municipalities.
Whenever any person is arrested by a patrol officer for a traffic violation the provisions of Sections 47-16-101 through 47-16-114 of this title shall apply.
