Saddlemounts - Exemptions and restrictions - Driveaway permits.
A.  1.  Pursuant to such rules as may be prescribed by Oklahoma
agencies of jurisdiction, Oklahoma motor carriers may engage in any
activity in which carriers subject to the jurisdiction of the
federal government may be authorized by federal legislation to
engage.  Provided further, the Transportation Commission shall
formulate for the State Trunk Highway System, including the National
System of Interstate and Defense Highways, and for all other
highways or portions thereof, rules governing the movement of
vehicles or loads which exceed the size or weight limitations
specified by the provisions of this chapter.
2.  Such rules shall be the basis for the development of a
system by the Executive Director of the Department of Transportation
for the issuance of permits for the movement of oversize or
overweight vehicles or loads.  Such system shall include, but not be
limited to, provisions for duration, seasonal factors, hours of the
day or days when valid, special requirements as to flags, flagmen
and warning or safety devices and other such items as may be

consistent with the intent of this section.  The permit system shall
include provisions for the collection of permit fees as well as for
the issuance of the permits by telephone, electronic transfer or
such other methods of issuance as may be deemed feasible.
3.  The Department of Transportation is authorized to charge a
fee of Two Dollars ($2.00) for each permit requested to be issued by
facsimile machine or by any other means of electronic transmission,
transfer or delivery.  The fee shall be in addition to any other fee
or fees assessed for the permit.  The fee shall be deposited in the
State Treasury to the credit of the Department of Transportation and
the monies shall be expended by the Department of Transportation
solely for the purposes provided for in this chapter.
4.  It is the purpose of this section to permit the movement of
necessary overweight and oversize vehicles or loads consistent with
the following obligations:
a. protection of the motoring public from potential
traffic hazards,
b. protection of highway surfaces, structures, and
private property, and
c. provision for normal flow of traffic with a minimum of
interference.
B.  The Transportation Commission shall prepare and publish a
map of this state showing by appropriate symbols the various highway
structures and bridges in terms of maximum size and weight
restrictions.  This map shall be titled "Oklahoma Load Limit Map"
and shall be revised periodically to maintain a reasonably current
status and in no event shall a period of two (2) years lapse between
revisions and publication of the printed version of the Oklahoma
Load Limit Map.  This map shall also be made available by the
Department of Transportation on the Internet, and in no event shall
a period of six (6) months lapse between revisions of the
information provided on the Internet.  Provided, further, the
Secretary of the Department of Transportation shall prepare and
publish a map of this state showing the advantages of this state as
a marketing, warehousing and distribution network center for motor
transportation sensitive industries.
C.  The Executive Director of the Department of Transportation,
or an authorized representative, shall have the authority, within
the limitations formulated under provisions of this chapter, to
issue, withhold or revoke special permits for the operation of
vehicles or combinations of vehicles or loads which exceed the size
or weight limitations of this chapter.  Every such permit shall be
carried in the vehicle or combination of vehicles to which it refers
and shall be open to inspection by any law enforcement officer or
authorized agent of any authority granting such permit, and no
person shall violate any of the terms or conditions of such special
permit.

D.  It shall be permissible in the transportation of empty
trucks on any road or highway to tow by use of saddlemounts, i.e.,
mounting the front wheels of one vehicle on the bed of another
leaving the rear wheels only of such towed vehicle in contact with
the roadway.  One vehicle may be fullmounted on the towing or towed
vehicles engaged in any driveaway or towaway operation.  No more
than three saddlemounts may be permitted in such combinations.  The
towed vehicles shall be securely fastened and operated under the
applicable safety requirements of the United States Department of
Transportation and such combinations shall not exceed an overall
length of seventy-five (75) feet.  Provided, a driveaway saddlemount
with fullmount vehicle transporter combination may reach an overall
length of ninety-seven (97) feet on the National Network of
Highways.
E.  The Executive Director of the Department of Transportation,
upon application of any person engaged in the transportation of
forest products in the raw state, which is defined to be tree-length
logs moving from the forest directly to the mill, or upon
application of any person engaged in the hauling for hire or for
resale of round baled hay with a total outside width of eleven (11)
feet or less, shall issue an annual permit, upon payment of a fee of
Twenty-five Dollars ($25.00) each year, authorizing the operation by
such persons of such motor vehicle load lengths and widths upon the
highways of this state except on the National System of Interstate
and Defense Highways.  Provided, however, the restriction on use of
the National System of Interstate and Defense Highways shall not be
applicable to persons engaged in the hauling of round baled hay with
a total outside width of eleven (11) feet or less.
F.  The Executive Director of the Department of Transportation,
upon application of any person engaged in the transportation of
overwidth or overheight equipment used in soil conservation work
with a total outside width of twelve (12) feet or less, shall issue
an annual permit, upon payment of a fee of Twenty-five Dollars
($25.00) each year, authorizing the operation by such persons of
such motor vehicle load lengths and widths upon the highways of this
state except on the National System of Interstate and Defense
Highways.
G.  Farm equipment including, but not limited to, implements of
husbandry as defined in Section 1-125 of this title shall be
exempted from the requirement for special permits due to size.  Such
equipment may move on any highway, except those highways which are
part of the National System of Interstate and Defense Highways,
during the hours of darkness and shall be subject to the
requirements as provided in Section 12-215 of this title.  In
addition to those requirements, tractors pulling machinery over
thirteen (13) feet wide must have two amber flashing warning lamps
symmetrically mounted, laterally and widely spaced as practicable,

visible from both front and rear, mounted at least thirty-nine (39)
inches high.
H.  Any rubber-tired road construction vehicle including rubber-
tired truck cranes and special mobilized machinery either self-
propelled or drawn carrying no load other than component parts
safely secured to the machinery and its own weight, but which is
overweight by any provisions of this chapter, shall be authorized to
move on the highways of this state.  Movement of such vehicles shall
be authorized on the National System of Interstate and Defense
Highways only by special permit secured from the Executive Director
of the Department of Transportation or an authorized representative
upon determination that the objectives of this section will be
served by such a permit and that federal weight restrictions will
not be violated.  The special permit shall be:
1.  A single-trip permit issued under the provisions of this
section and Section 14-116 of this title; or
2.  A special annual overweight permit which shall be issued for
one calendar year period upon payment of a fee of Sixty Dollars
($60.00).
The weight of any such vehicle shall not exceed six hundred
fifty (650) pounds multiplied by the nominal width of the tire.  The
vehicle shall be required to carry the safety equipment adjudged
necessary for the health and welfare of the driving public.  If any
oversized vehicle does not come under the other limitations of the
present laws, it shall be deemed that the same shall travel only
between the hours of sunrise and sunset.  The vehicle, being
overweight but of legal dimension, shall be allowed continuous
travel.  The vehicles, except special mobilized machinery, shall be
exempt from the laws of this state relating to motor vehicle
registration, licensing or other fees or taxes in lieu of ad valorem
taxes.
I.  1.  When such machinery has a width greater than eight and
one-half (8 1/2) feet, or a length, exclusive of load, of forty-five
(45) feet, or a height in excess of thirteen and one-half (13 1/2)
feet, then the permit may restrict movement to a fifty-mile radius
from an established operating base, and may designate highways to be
traveled, hours of travel and when flagmen may be required to
precede or follow the equipment.
2.  Possession of a permit shall in no way be construed as
exempting such equipment from the authority of the Executive
Director of the Department of Transportation to restrict use of
particular highways, nor shall it exempt owners or operators of such
equipment from the responsibility for damage to highways caused by
movement of the equipment.  Nothing in this subsection shall apply
to machinery used in highway construction or road material
production.

3.  Upon the issuance of a special mobilized machinery driveaway
permit as provided in this subsection, special mobilized machinery
manufactured in Oklahoma shall be permitted to move upon the
highways of this state from the place of manufacture to the state
line for delivery and exclusive use outside the state, and may be
temporarily returned to Oklahoma for modification and repair, with
subsequent movement back out of the state.  Special driveaway
permits for such movements shall be issued by the Executive Director
of the Department of Transportation, who may act through designated
agents, upon the payment of a fee in the amount of Fifteen Dollars
($15.00) for each movement.
4.  The size of the special mobilized machinery shall not be
such as to create a safety hazard in the judgment of the Executive
Director of the Department of Transportation.  Permits for such
special mobilized machinery shall specify a maximum permissible road
speed of sixty (60) miles per hour, designate safety equipment to be
carried and may exclude use of highways of the interstate system.
5.  When such equipment has a width greater than eight and one-
half (8 1/2) feet, or a length exclusive of load of forty-five (45)
feet, or a height in excess of thirteen and one-half (13 1/2) feet,
the permit may designate highways to be traveled, hours of travel
and when flagmen may be required to precede or follow the equipment.
6.  Possession of a special driveaway permit shall in no way be
construed as exempting such equipment from the authority of the
Executive Director of the Department of Transportation to restrict
use of particular highways, nor shall it exempt the owners or
operators of such equipment from the responsibility for damage to
highways caused by the movement of such equipment.
