penalties.

Oklahoma Statutes - Title 47. Motor Vehicles Page 496

A. Any person driving a vehicle on a highway shall drive at a

careful and prudent speed not greater than nor less than is

reasonable and proper, having due regard to the traffic, surface,

and width of the highway and any other conditions then existing. No

person shall drive any vehicle upon a highway at a speed greater

than will permit the driver to bring it to a stop within the assured

clear distance ahead.

B. Except when a special hazard exists that requires lower

speed for compliance with subsection A of this section, the limits

specified by law or established as hereinafter authorized shall be

maximum lawful speeds, and no person shall drive a vehicle at a

speed in excess of the following maximum limits:

1. On a highway, part of a highway, or on roads located on

lands owned by a state beneficiary public trust, unless otherwise

established in law, a speed established by the Department of

Transportation on the basis of engineering and traffic

investigations used to determine the speed that is reasonable and

safe under the conditions found to exist on the highway, part of the

highway, or road;

2. For a school bus, fifty-five (55) miles per hour on paved

two-lane roads except on the state highway system, the interstate

highway system, and the turnpike system where the maximum shall be

sixty-five (65) miles per hour;

3. On any highway outside of a municipality in a properly

marked school zone, twenty-five (25) miles per hour, during certain

times as provided in Section 11-806.1 of this title and provided the

zone is marked with appropriate warning signs placed in accordance

with the latest edition of the Manual on Uniform Traffic Control

Devices for Streets and Highways. The Department of Transportation

may determine on the basis of an engineering and traffic

investigation that a speed limit higher than twenty-five (25) miles

per hour may be reasonable and safe under conditions as they exist

upon a highway, and post an alternative school zone speed limit.

The Department shall mark such school zones, or entrances and exits

onto highways by buses or students, so that the maximum speed

provided by this paragraph shall be established therein. Exits and

entrances to controlled-access highways which are within such school

zones shall be marked in the same manner as other highways. The

county commissioners shall mark such school zones along the county

roads so that the maximum speed provided by this paragraph shall be

established therein. The signs may be either permanent or

temporary. The Department shall give priority over all other

signing projects to the foregoing duty to mark school zones. The

Department shall also provide other safety devices for school zones

which are needed in the opinion of the Department;

4. Twenty-five (25) miles per hour or a posted alternative

school zone speed limit through state schools located on the state-

owned land adjoining or outside the limits of a corporate city or

town where a state educational institution is established;

5. Thirty-five (35) miles per hour on a highway in any state

park or wildlife refuge. Provided, however, that the provisions of

this paragraph shall not include the State Capitol Park area, and no

person shall drive any vehicle at a rate of speed in excess of

fifty-five (55) miles per hour on any state or federal designated

highway within such areas; and

6. For any vehicle or combination of vehicles with solid rubber

or metal tires, ten (10) miles per hour.

The maximum speed limits set forth in this section may be

altered as authorized in Sections 11-802 and 11-803 of this title.

C. The Transportation Commission is hereby authorized to

prescribe maximum and minimum speeds for all vehicles and any

combinations of vehicles using controlled-access highways. Such
or combination of vehicles with solid rubber

or metal tires, ten (10) miles per hour.

The maximum speed limits set forth in this section may be

altered as authorized in Sections 11-802 and 11-803 of this title.

C. The Transportation Commission is hereby authorized to

prescribe maximum and minimum speeds for all vehicles and any

combinations of vehicles using controlled-access highways. Such

regulations shall become effective after signs have been posted on

these highways giving notice thereof. Such regulations may apply to

an entirely controlled-access highway or to selected sections

thereof as may be designated by the Transportation Commission. A

speed limit of seventy-five (75) miles per hour may be set in

locations comprising rural segments of the interstate highway system

by the Transportation Commission; provided, however, that speed is

determined to be safe and reasonable after a traffic or engineering

study has been completed by the Department. It shall be a violation

of this section to drive any vehicle at a faster rate of speed than

such prescribed maximum or at a slower rate of speed than such

prescribed minimum. However, all vehicles shall at all times

conform to the limits set forth in this section.

Copies of such regulations certified as in effect on any

particular date by the Secretary of the Transportation Commission

shall be accepted as evidence in any court in this state. Whenever

changes have been made in speed zones, copies of such regulations

shall be filed with the Commissioner of Public Safety.

D. The Oklahoma Turnpike Authority is hereby authorized to

prescribe maximum and minimum speeds for trucks, buses and

automobiles using turnpikes; provided, however, a speed limit of

eighty (80) miles per hour may be set in locations comprising the

turnpike system, as may be approved by the Authority. The

regulation pertaining to automobiles shall apply to all vehicles not

commonly classified as either trucks or buses. Such regulations

shall become effective only after approval by the Commissioner of

Public Safety, and after signs have been posted on the turnpike

giving notice thereof. Such regulations may apply to an entire

turnpike project or to selected sections thereof as may be

designated by the Oklahoma Turnpike Authority. It shall be a

violation of this section to drive a vehicle at a faster rate of

speed than such prescribed maximum speed or at a slower rate of

Oklahoma Statutes - Title 47. Motor Vehicles Page 498

speed than such prescribed minimum speed. However, all vehicles

shall at all times conform to the requirements of this section.

Copies of such regulations, certified as in effect on any

particular date by the Secretary of the Oklahoma Turnpike Authority,

shall be accepted in evidence in any court in this state.

E. The driver of every vehicle shall, consistent with the

requirements of subsection A of this section, drive at an

appropriate reduced speed when approaching and crossing an

intersection or railway grade crossing, when approaching and going

around a curve, when approaching a hillcrest, when driving upon any

narrow or winding roadway, and when special hazard exists with

respect to pedestrians or other traffic, or by reason of weather or

highway conditions. The Department of Transportation and the

Oklahoma Turnpike Authority may post, by changeable message sign or

other appropriate sign, a temporary reduced speed limit for

maintenance operations or when special hazards with respect to

pedestrians, other traffic, an accident, by reason of weather, or

other hazardous highway conditions exist.

F. 1. No person shall drive a vehicle on a county road at a

speed in excess of fifty-five (55) miles per hour unless posted

a. the board of county commissioners may determine, by

resolution, a maximum speed limit which shall apply to

all county roads which are not otherwise posted for

speed,

b. the board of county commissioners shall provide public

notice of the speed limit on all nonposted roads by

publication in a newspaper of general circulation in

the county. The notice shall be published once weekly

for a period of four (4) continuous weeks, and

c. the board of county commissioners shall forward the

resolution to the Director of the Department and to

the Commissioner of Public Safety.

2. The Department shall post speed limit information, as

determined pursuant to the provisions of subparagraphs a through c

of paragraph 1 of this subsection, on the county line marker where

any state highway enters a county and at all off-ramps where

interstate highways or turnpikes enter a county. The signs shall

read as follows:

ENTERING __________ COUNTY

COUNTY ROAD SPEED LIMIT

UNLESS POSTED OTHERWISE

The appropriate board of county commissioners shall reimburse

the Department the full cost of the signage required herein.
