Oversize/Overweight Permits
PURPOSE: This rule provides a uniform system for issuing special
permits to regulate vehicles used on state highways that when
loaded exceed the limitations on length, width, height, and/or
weight established in Chapter 304, RSMo.
PUBLISHER’S NOTE: The secretary of state has determined that
publication of the entire text of the material that is incorporated
by reference as a portion of this rule would be unduly cumbersome
or expensive. This material as incorporated by reference in this
rule shall be maintained by the agency at its headquarters and
shall be made available to the public for inspection and copying
at no more than the actual cost of reproduction. This note applies
only to the reference material. The entire text of the rule is printed
here.
(1) General Regulations for Oversize/Overweight Permits.
(A) In the design and fabrication of all vehicles, machinery,
equipment, structures, buildings, or other units or components,
careful consideration must be given to the legal and physical
limitations applicable to all available forms of transportation
between point of fabrication and the original or subsequent
destinations.
(B) Except for the following exceptions, permits will not be
granted for travel on the state highway system for movement
of a load reducible in size or weight. Reducible portions of any
oversize or overweight load shall include but are not limited to
any attachment, accessory, member, or assembly designed to
be detached with hand tools:
1. Farm products (hay), and farm equipment with dual
tires, and construction equipment with blade/bucket attached,
but only as permitted in sections (6) and (10);
2. Emergency response vehicles loaded with salt, sand,
chemicals, or a combination thereof, with or without a plow
or blade attached in front, and being used for the purpose
of spreading the material on state highways that are or may
become slick or icy;
3. Military vehicles transporting marked military equipment or material; or
4. A vehicle carrying raw fluid milk products from a farm
and/or raw milk products to or from a milk plant, receiving
station, or transfer station.
(C) Unladen vehicles or combinations are to comply with
legal size and weight limitations as listed in Chapter 304 of
the Missouri Revised Statutes unless exceptions can be justified
by safety considerations based on an oversize or overweight
object to be transported by the vehicle.
(D) Economic factors in either the saving of time or costs
for routing will not be considered of primary importance in
the routing process, and the department reserves the right to
designate routing and travel time for all movements. Safety,
structure capacities and clearances, roadway widths, and traffic
volumes will all be considered in route determination. The
routing will primarily use the designated state highway system
and be as direct as possible. When streets or highways off the
state highway system are used, it will be the responsibility of
the applicant to obtain approval from the agency responsible
for that off-state highway and adhere to all bridge capacity
postings off the state highway system.
(E) Limitations for all oversize and overweight load
movements will be determined by the least hazardous road
conditions and volume of traffic which will be encountered
and the practical capacity of the roadway, structures, and
the vehicle involved, based upon axle loads. All responses to
requests for routing approval prior to application are furnished
for general information only. Due to constantly changing
highway conditions, such routing approval is subject to change
without notice.
(F) Exceptions may be made for feasible oversize and/
or overweight movements certified as essential to national
defense, upon receipt of written documentation by designated
officials within the Defense Department.
(G) Permits may specify maximum and minimum speeds
to reduce hazards or control impact factors on pavement or
structures and may specify lane restrictions while crossing
structures to provide for better load distribution to the
structural members of that structure. Power units shall have
sufficient weight and power to handle the load safely and
maintain reasonable speeds.
(H) Each single trip permit covers the movement of one
(1) load only, between one (1) origin and one (1) destination,
except for the multi-stop permit designed for transportation
of farm implement delivery only. Legal size loads will not
be permitted as part of a multi-stop permit. Moves must be
completed in seven (7) moving days.
(I) Movement is restricted on the following holidays: New
Year’s Day (January 1), Memorial Day (last Monday in May),
Independence Day (July 4 or designated day of observation),
Labor Day (first Monday in September), Thanksgiving Day
(fourth Thursday in November), and Christmas Day (December
25).
1. Restrictions will begin at 12:00 noon on the last business
day preceding the holiday and apply until one-half (1/2) hour
before sunrise on the first business day following observation.
When Independence Day falls on a Saturday, the holiday will
be observed on the preceding Friday. When Independence Day
falls on a Sunday, the holiday will be observed on the following
Monday.
(J) The permittee may travel a distance of one (1) mile onto
another contiguous state highway for food, fuel, repairs,
and rest, provided that no structures are crossed, no posted
weight limits are exceeded, travel under overhead structures
can be completed safely, and oversize loads do not cause
an obstruction. All other provisions of the permit must be
followed.
(K) Travel under permit must be with properly licensed,
insured, and permitted vehicles under Chapters 260, 301
through 307, 390, and 622 of the Missouri Revised Statutes, and
vehicles must be licensed for maximum weights in order to
obtain overweight permits.
(L) All references to recognized sunrise and sunset times,
as applicable to the travel restrictions herein, shall be in
accordance with the National Oceanic and Atmospheric
Administration – National Weather Service.
(M) References to highway types utilized throughout this
rule shall mean the following:
1. Divided highway—A travelway with two (2) or more
traffic lanes in opposing directions separated by a physical
barrier, raised curbed median, or depressed earth/vegetated
median;
2. Multilane undivided highway—A travelway with two
(2) or more traffic lanes in opposing directions that is not
separated by a median or other physical barrier. Undivided
highways are typically delineated by pavement markings only;
and
3. Two- (2-) lane highway—A travelway typically with one (1)
traffic lane in each opposing direction. This definition includes
travelways with intermittent or directionally alternating
continuous third lane sections designed to facilitate turning,
climbing, passing, and/or other traffic management purposes.
(2) Financial Responsibility.
(A) An applicant for an oversize/overweight permit shall
have coverage for bodily injury to, or death of, an individual
and for loss or damage to property. Coverage shall be effective
during all of the applicant’s oversize/overweight operations
authorized under such permit covering each motor vehicle
operating under the authority of the applicant’s permit in
amounts not less than the following:

(B) Any automobile insurance policy required under
this administrative rule shall not include coverage of the
cargo transported under the permit, and instead, any cargo
transported by the applicant under a permit issued under this
administrative rule shall be insured under a separate insurance
policy.
(C) The Motor Carrier Services’ director or his/her representative may reject an applicant’s request for a permit or suspend
the applicant’s privileges of obtaining oversize/overweight

(12) Procedures for Emergency Movements.
(A) Railroad derailments and other civil or natural disasters
may create the necessity for an emergency movement by
oversize/overweight vehicles. The Missouri Department of
Transportation shall also issue emergency utility response
permits for the transporting of utility wires or cables, poles,
and equipment needed for repair work immediately following
a disaster where utility service has been disrupted, except for
and excluding movements under section (15).
(B) Emergency movements into or within the state may be
allowed day or night, seven (7) days a week by permit or verbal
approval from either the motor carrier compliance supervisor
or other designated motor carrier services representative.
(C) Following verbal approval, an official permit covering
each emergency movement must be obtained on the first
working day immediately following the move.
(D) Verbal authority for an emergency movement may be
granted only after confirmation that an emergency exists by
an authorized representative of the permittee who shall be
required to furnish information on conditions at the location of
the emergency and the name of the company to perform the
emergency service.
(E) The Missouri Department of Transportation representative
granting authority for an emergency movement will advise the
Missouri State Highway Patrol that the move is authorized and
furnish information on the vehicle involved, such as make
and license of hauling units, axle weights, load dimensions,
location, routes of travel, and the estimated time of the
movement. The restriction prohibiting travel in tourist areas,
during curfew hours, at night, and on holidays or holiday
weekend periods will be waived for the initial response to the
emergency site.
(F) Permits for return trips will be issued during regular
working hours only and each unit must comply with the
permit regulations’ limitations for weight and dimensions.
(G) Emergency movements are not exempt and will not be
waived of the requirement to stop at weigh stations.
(H) Violations are not in the interest of public safety and
any misrepresentation in the application, verbal request for
a permit, or violation of the terms of the verbal authority for
movement may result in denial of future authorizations being
granted for an emergency move.

2. Movement of a building that will not allow one- (1-) way
TRANSPORTATION
traffic to pass the load will be limited to no more than one (1)
mile in length on the state highway system if the traffic volume
on the proposed route exceeds five hundred (500) vehicles per
day. If the traffic volume is less than five hundred (500) vehicles
per day, movement will be considered up to a distance of three
(3) miles on the state highway system.
3. Movement of a building greater than sixteen feet (16')
in overall width that will allow one- (1-) way traffic to pass the
load will be limited to no more than two (2) miles on the state
highway system if the traffic volume on the proposed route
exceeds two thousand (2,000) vehicles per day. If the traffic
volume is less than two thousand (2,000) vehicles per day,
movement will be considered up to a distance of ten (10) miles
on the state highway system.
4. The traveled distances listed in the above two (2)
paragraphs reflect the total miles of the move on the state
highway system rather than miles allowed to move per
attempt. Short segments of the state highway system may
be used in a move provided the total mileage allowed on the
state highway system is not exceeded. The district engineer or
his/her representative may consider a longer travel distance if
the entire move can be made during periods of lower traffic
volumes listed in the above two (2) paragraphs of this section.
Additional restrictions regarding travel during adverse weather
conditions are at the discretion of the Missouri Department of
Transportation district engineer or his/her representative.
(B) The allowable overall height, width, length, and time of
travel shall be based on physical features and traffic volumes
along the route. Bridges posted with a maximum weight limit of
less than forty (40) tons should be avoided and will be analyzed
for the type of vehicle and load prior to receiving approval to
cross that bridge. All axles on the hauling unit shall be load
carrying with a maximum degree of equalization. The district
engineer or his/her representative shall determine whether or
not the hauling unit, number of axles, and axle arrangements
are acceptable. When it is determined a bridge analysis is
required, an additional fee shall be charged to recover bridge
analysis costs. See subsection (4)(B). Loads in excess of sixteen
feet (16') in width may require a sketch displaying the side and
rear view of the load with dimensions including any overhang.
(C) If the load is over seventeen feet (17') high the applicant
shall check all overhead clearance restrictions and provide
written documentation from any involved utility company
indicating approval to disturb aerial lines across the route. The
applicant must also submit written acknowledgment from all
cities/counties in which the move occurs. If it is necessary to
adjust, modify, or remove state-owned property such as signal
and sign mast arms, flashers, signs, etc., a qualified contractor
approved by the Missouri Department of Transportation shall
be hired by the applicant to perform the necessary adjustment
or removal and replacement. See section 324.721, RSMo, for
additional information.
(D) For the purpose of moves under section (16), the applicant
must have a current house-mover license or be the individual
owner of the house being transported. As applicable, the
applicant must be compliant with all necessary operating
