Combination Trucks Only
Farm-vehicle-drivers of combination semi-trucks (within 150 air-miles of their farm) are exempt from:
Both Combination and Straight Trucks
Farm-vehicle-drivers of both combination (articulated) trucks and straight trucks operating within 150 air-miles of
their farm, wholly within Missouri, not hauling for-hire or placarded hazardous materials, are exempt from:
Farmers and Agri-Business Operations
The provisions of this part shall not apply during planting and harvesting periods, as determined by each State,
to drivers transporting
Note: Crossing state lines may require full compliance with this requirement,
depending on that adjoining state's planting and harvesting season. While Missouri's is year round, other states do vary.
Missouri Farm License Plate Exemptions
Trucks with Missouri farm license plates designated for farm use by the "F" tab, and licensed for 42,000
pounds or less, are exempt from:
This Missouri farm plate exclusion basically exempts farm vehicles licensed for 42,000 lbs or less from the DOT Federal Motor Carrier
Safety Regulation driver qualifications and file, medical qualification & certification card, hours-of-service rules, and the maintenance
Farmers and farm truck drivers are still required to have a Class E Missouri driver’s license or CDL. If a CDL is required, then
drug & alcohol testing requirements must be met also. Drivers must be at least 18 years old, speak English, and be physically
capable of operating a truck safely. All trucks must be operated with the proper equipment and comply with Missouri state traffic laws.
Farm Trucks as Commercial Motor Vehicles (CMVs)
Farm trucks are considered commercial motor vehicles (CMV) if they meet the size description of a CMV, which is basically a truck with a gross
weight over 10,000 lbs. In Missouri this varies some. Please see the Commercial Motor Vehicle definition in the glossary.
Marking of Farm Trucks
Federal regulations and Missouri State Statutes require that all trucks must have markings on their truck with at least the
operating business or farm name and location of the business or farm, on both sides of the truck. In certain cases a USDOT
number may be required if crossing state lines at all or hauling for hire. These requirements do include farm trucks.
Insurance Requirements for Farm Trucks
You need to have at least the minimum required amount of state liability insurance coverage on any vehicles operated.
Higher public liability may be required if you carry bulk hazardous materials, operate for-hire, or various other factors.
Commercial Driver’s License’s (CDL) Requirements for Farm Trucks
However, if you strictly meet all of the following guidelines, no CDL is required.
The farmer operating their "farm vehicle"
as a "farm-vehicle-driver"
are exempt from the CDL requirements if:
A CDL is required if your truck and/or trailer is required to be
placarded due to the Hazardous Materials carried, no matter what size or
gross vehicle weight rating (GVWR) of the truck and trailer.
Missouri Class E Driver's License
This is Missouri's non-CDL license for commercial vehicles that do not require a CDL. This license is required for all non-family
employee farm truck drivers if they do not have a CDL.
CDL Required Drug and Alcohol Testing Rules
Drivers who are required to have a CDL for the type of truck operated must also comply with the controlled substance
and alcohol testing requirements of the Federal Motor Carrier Safety Regulations (FMCSR). These include such things as:
These are just some of the basic requirements. Please find out more by reviewing the actual regulations. For
further clarification please call or view websites indicated in the contact information.
Minimum Age for Farm Truck Drivers
Drivers of a commercial vehicle must be at least 18 years old. Drivers must be at least 21 years old if:
Driver's License Requirements
If a CDL is not required (see page 5 for CDL requirements), then all non-family member farm employees must have at least a Missouri Class E
driver's license (previously known as the Missouri Chauffeur's License).
Missouri Farm License Plate Exemptions
Trucks with Missouri farm license plates designated for farm use by the "F" tab, and licensed for 42,000 pounds or less,
are exempt from the general safety regulations (FMCSR Parts 390-397) when operating in Missouri intrastate farm commerce only.
The Missouri "F" tab farm plate regulations exemptions are only applicable when a vehicle is lawfully licensed for a gross
weight of 42,000 pounds or less (not in excess of its licensed gross weight of 42,000 pounds) and is designated "F" for
farm use in accordance with the applicable requirements of Missouri law. The vehicle may only transport property to or from a farm
owned or operated by that person and the property transported to the farm is only for use in the operation of this farm.
A farmer operating on a local commercial motor vehicle license plate with a farm tab may not make a for-hire haul! Farmers also
lose all farmer exemptions when doing this. Farm truck drivers must still have at least a Missouri class E driver's license,
or a CDL if required, be at least 18 years old, and comply with Missouri state traffic laws.
Note: The above exemption based on Missouri "F" tab license plates exists separately from
all other regulations and does relate to or overlap any other requirements or exemptions discussed in this booklet.
All persons who operate a commercial vehicle are considered "drivers" regardless of pay/non-pay status, being the vehicle owner, etc. In general,
all drivers must be of the proper age, speak English, have a valid operating license, not be physically impaired (i.e. not physically incapable
of operating a truck), and follow all other applicable state laws.
Medical Certification Requirements
In certain cases, drivers (including the farmer) must be medically examined and certified (DOT physical and certification) to operate a commercial
vehicle farm truck. They must maintain records of these qualifications by carrying the DOT medical certification card while operating their
farm truck commercial vehicle.
There are three exceptions from this requirement:
Recordkeeping of Driver Qualifications
Requirements will vary according to what specific exemptions apply, but in general a complete driver qualification file for each Commercial Vehicle
farm truck driver (including the owner/operator/farmer) should contain the following required information:
The driver qualification file for each Commercial Vehicle farm truck driver must be maintained by the
farm business owner and kept on file there. One exception from most of the above requirements is the Missouri
"F" tab Farm Plate Exemption: Trucks with Missouri farm license plates designated for farm use by the
"F" tab, and licensed for 42,000 pounds or less, are exempt from the general safety regulations
(FMCSR Parts 390-397) when operating in Missouri intrastate farm commerce only.
Farmers are not exempt from the Drug & Alcohol testing requirements if the driver is required to have a CDL:
These farm-vehicle-drivers are exempt when operating their "farm vehicle" within Missouri,
unless adjoining state's have a reciprocal agreement and depending on that state's planting and
harvesting season. Missouri does have such an Agreement with all of its surrounding states other than Kentucky.
Compliance With Hours-of-Service Requirements
Generally, all Commercial Vehicles must follow the following hours-of-service rules:
These apply to all Commercial Vehicles. However two exemptions are allowed from these requirements:
Note: Crossing state lines may require full compliance with this area, depending on
that adjoining state's planting and harvesting season; Missouri's is year round, other states vary.
Hours-of-Service Logbooks or Time records for Farm Truck Drivers
Generally all working hours, driving hours, and off-duty time must be documented by either using a logbook
or time record. These must be kept showing all driving time, all working time, and off-duty time.
Two exemptions are allowed for farmers from these requirements:
Note: Crossing state lines may require full compliance with this area,
that adjoining state's planting and harvesting season; Missouri's is year round, other states vary.
Truck Maintenance Requirements
Equipment and Maintenance Rules for Farm Trucks
All farm trucks must be operated safely with the proper equipment such as lighting, brakes, tires, load-securement,
steering and suspension parts, etc. This means that all equipment, parts, and accessories must be properly
maintained according to state and federal regulations. Inspections, repairs, and maintenance must be done
and documented as explained below.
Maintenance Records and Proof of Repairs
All farm trucks and trailers operated on a public roadway must have a complete maintenance file
containing documentation for each truck and trailer listing:
Note: One exception from the Federal Motor Carrier
Safety Regulations (FMCSR) maintenance requirements, which is the Missouri "F" tab Farm
Plate Exemption. Trucks with Missouri farm license plates designated for farm use
by the "F" tab, and licensed for 42,000 pounds or less, are exempt from the
federal maintenance regulations when operating in Missouri intrastate farm commerce only.
Safety Inspection Requirements for Drivers
All drivers are required to do a daily pre-trip "walk around" inspection of the truck and
trailer before operating it on any roadway to ensure it is safe. This is to find and correct
vehicle and trailer defects, load securement problems, and equipment violations before
they cause accidents and injure someone!
When a driver is made aware of a safety defect, the driver must complete a daily
vehicle inspection post-trip report showing that the defects noted and
repaired for that were repaired.
Exemptions from this driver daily vehicle inspection report requirement include:
Economic Regulations, Licensing, and Permits
Besides the safety regulation requirements, other rules and fees apply to farmers operating trucks both
within Missouri and interstate. These include fuel tax licenses, over-dimension/over-weight
(OD/OW permits), apportioned license plates, for-hire authority, etc.
Intrastate (within Missouri)
Overdimension Loads (OD)
No OD permits are needed on Missouri state highways for farmers occasionally and temporarily transporting an agricultural
implement for a short distance on a state highway, or transporting hay as a farm product. OD permits are always required
on the federal highway (interstate) system. Farm drivers must operate safely and in compliance with applicable rules and
laws at all times or the OD permit will be voided.
Overweight Loads (OW)
Farmers must comply with the maximum legal weight limits or obtain an OW permit. Overweight loads are not exempt and always
require a proper OW permit. Fees start at $15 with an additional $20 for every 10,000 lbs over the state maximum legal weight limit.
Reminder: Depending on the dimensions of the load and time of the movement, when traveling under an OD or OW permit,
visible warning signs, flags, and lighting (when required due to darkness or weather) may be needed on the
vehicle! This includes transporting hay!
Limits vary by roadway designation, commercial zone operation, and the type of vehicle.
Generally, current Missouri statutory limits are as follows:
This is based on gross weight, bridge weight, axle weight and axle spacings. These vary,
so please call or visit our website for information regarding RSMo 304.180 for legal weights
according to the number of axles and axle spacings.
If hauling livestock 85,500 lbs. is legal on state maintained highways, not allowed on the
interstate system and is only good for livestock. The increased weight for grain and grain
co-products is now (10% over allowable vehicle configuration axle limitations).
Not allowed on the interstate system and is only good for grain or grain co-products.
Weight/height commercial zones set by statute within Missouri:

Missouri For-Hire Hauling Certificate of Authority
For intrastate authority within Missouri, there are a few simple steps to complete:
Note: If you fall under these for-hire hauling requirements, you are then
NOT operating as a farmer and none of the previous exemptions from the safety regulations covered will apply to you.
You also may not haul for-hire using a Missouri farm license plate.
Interstate (beyond Missouri)
Operation Beyond/Across Missouri State Lines
Any Commercial Motor Vehicle (CMV) crossing state lines, including farmers and farm trucks, must register with the
Federal Motor Carrier Safety Administration and obtain a USDOT number. There may be a charge to receive this
required number for private carriers such as farmers. Presently, this can be done by phone, mail, or via the Internet.
Note: There are no exceptions from this requirement, if you cross state
lines at all in a Commercial Motor Vehicle with a gross vehicle weight rating (GVWR) or gross combination weight
rating (GCWR), even as a farmer.
Hauling For-Hire Beyond Missouri
For interstate operating authority, you must apply to the USDOT, Federal Motor Carrier Safety Administration
for this authority. You may obtain this through the U.S. Department of Transportation. Fees start at
approximately $300 and increase from there for each additional authority type needed.
Note: If you fall under these requirements, then you are NOT
operating as a farmer and none of the previous exemptions from the safety regulations covered will apply to you.
License Plate Requirements for Interstate Transportation
Missouri farm license plates are essentially local license plates to be used with a 50-mile radius. There are some
exceptions within Missouri for occasionally going beyond the 50-mile radius for farm business and personal use.
However, adjoining states may have different rules for farm license plates. Farmers are urged to check with the
Missouri Department of Revenue, MODOT - Motor Carrier Services, or equivalent agencies of the state in which
they will be traveling.
If engaged in interstate for-hire transportation, farmers may need to obtain an apportioned license plate.
Note: If you are required to have an apportioned license plate, then you are
NOT operating as a farmer and none of the previous safety regulation exemptions explained will not apply to you.
Fuel Tax License for Farmers
As a farmer operating across any state lines, International Fuel Tax Agreement (IFTA) license requirements
apply if any of these two conditions is present:
International Fuel Tax Agreement (IFTA) is a required license to operate in interstate commerce and
applies to farmers by just crossing state lines. The license is free but requires quarterly reports
and submission of fuel taxes. For infrequent trips out of state, a 72-hour permit may be purchased
for $10 instead of obtaining this IFTA license.
The regulations and requirements in this booklet are explained in a very abbreviated manner and are only a
brief overview of some common requirements. The regulations should be consulted for a full explanation of
these rules and guidelines. They can be viewed on the websites listed below or copies obtained from any
regulatory supplier. The complete regulations and state statutes, while complex, will cover these
areas in much more detail and should be read in their entirety.
