Arkansas Livestock Trailer Laws: What Every Hauler Needs to Know Before Hitting the Road

Hauling livestock in Arkansas comes with real legal responsibilities that go well beyond hitching up a trailer and pointing the truck down the highway. Whether you are moving cattle between pastures, transporting hogs to market, or hauling horses to a show, Arkansas law — backed by federal regulations — sets specific standards for your trailer, your load, your license, and your documentation.

Getting any one of those elements wrong can mean fines, quarantined animals, or a trailer parked on the side of the road until you come into compliance. This guide walks you through every major requirement so you can haul with confidence and stay on the right side of Arkansas law.

Livestock Trailer Registration and Identification Requirements in Arkansas

Before your trailer rolls onto a public road in Arkansas, it must be properly registered. In Arkansas, trailers must be registered with the Arkansas Motor Vehicle Commission or an authorized agency before use on public roads. Registration confirms ownership, enables license plate issuance, and ensures compliance with state vehicle regulations.

When you go to register, come prepared with the right paperwork. Typical requirements include proof of ownership such as a title or bill of sale, and trailer registration fees are primarily determined by weight, gross vehicle weight rating (GVWR), and the trailer’s purpose. Livestock and farm trailers fall into their own category, and that classification matters for what you pay and what exemptions may apply to you.

Farm trailers and commercial trailers sometimes follow different rules. Farm trailers used for planting, harvesting, or transporting farm products may be eligible for lower fees or exemptions in some counties. If you operate your trailer under a farm LLC or hold agricultural tax exemptions, bring that documentation — documentation such as farm LLC status, tax exemptions, or organizational registrations may be required.

Once registered, keep your plate visible and your registration current. The license plate should be securely attached to the rear of the trailer, ensuring clear visibility to law enforcement and other road users. Trailer registrations in Arkansas require periodic renewal, typically on an annual basis. Renewal reminders may be issued by mail or email, and online renewal is often available. Failure to renew on time can result in penalties, late fees, or discrepancies in license plate status.

Pro Tip: If you use a farm or natural resources license plate (F-prefix), you must complete a qualifying affidavit confirming the vehicle’s agricultural use. Keep a copy of that affidavit in the cab — officers may ask to see it during a roadside stop.

For interstate movements, animal identification requirements layer on top of trailer registration. Most animals require a Certificate of Veterinary Inspection (CVI) issued within 30 days of entry. Entry permits are required for certain animals, including swine, camelids, cervids, ratites, zoo and exotic animals, rodeo bulls, and non-poultry birds. Cattle must have a CVI and individual ID, with additional testing potentially required for brucellosis or tuberculosis depending on origin. Horses require a CVI and a negative EIA (Coggins) test within the past 12 months.

If you haul goats or sheep, note that all sheep and goats imported into Arkansas shall be accompanied by a Certificate of Veterinary Inspection and shall meet the scrapie record requirement, which must be documented in addition to the certificate of veterinary inspection.

Structural and Safety Standards for Livestock Trailers in Arkansas

A livestock trailer has to do more than hold animals — it has to do so safely for both the animals and other drivers on the road. Arkansas follows federal safety standards for commercial motor vehicles and imposes its own requirements for trailer equipment.

Lighting is non-negotiable. Arkansas mandates that all trailers must have functional rear lights. Proper rear lighting is crucial for visibility, especially during low-light conditions like dusk or dawn. Your trailer must also have working brake lights and turn signals that are not obscured by the trailer body or its load.

Safety chains are a required safeguard on every tow. To prevent potential accidents in the event of a trailer disconnecting from its towing vehicle, Arkansas trailer laws require the use of safety chains. These chains serve as a vital safety measure, providing an additional layer of security during towing.

Braking systems become mandatory once your trailer crosses certain weight thresholds. For trailers exceeding certain weight thresholds, Arkansas regulations stipulate the need for a separate and efficient braking system. This ensures that the trailer can come to a halt safely and promptly when required, reducing the risk of accidents.

Important Note: Conveyances used to haul diseased or exposed animals carry a strict sanitation obligation. Owners and operators of trucks and other conveyances that have been used to move any livestock or poultry affected with or exposed to any infectious or contagious disease or to scabies or fever tick infestation shall be required to have such conveyances thoroughly cleaned and disinfected under official supervision before further use for the transportation of livestock or poultry.

Beyond lighting and brakes, the hitch connection itself must be rated for the load you are pulling. Most states require trailers to have a suitable hitch mechanism designed to handle the specific load. Trailer safety chains or cables are another common requirement. Make sure your hitch class and ball size match the trailer’s tongue weight rating — an undersized hitch is both a safety hazard and a compliance problem.

If you haul backyard livestock like chickens, you may also want to review Arkansas backyard chicken laws for any transport-related provisions that apply to poultry movements at the local level.

Size, Weight, and Load Limits for Livestock Trailers in Arkansas

Arkansas sets firm dimensional and weight limits for vehicles operating on its highways, and livestock trailers are no exception. Knowing these numbers before you load up prevents costly overweight citations and keeps your rig legal from the moment you pull onto the road.

For width and height, Arkansas allows a maximum width of 8 feet 6 inches and a maximum height of 14 feet on both the National Network and state supplemental highways. Semitrailers are permitted up to 53 feet 6 inches in length. These limits apply whether you are hauling cattle, hogs, or horses.

On gross weight, the federal and state standard applies: a maximum gross weight, including any allowable variance or tolerance, shall not exceed 80,000 pounds. Axle limits are equally important. The maximum single axle weight is 20,000 pounds, and the maximum tandem axle weight is 36,500 pounds.

There is one notable weight accommodation for livestock feed haulers specifically. Vehicles or combinations of vehicles with five axles and used exclusively by the owner of livestock or poultry for hauling animal feed to the owner’s livestock or poultry for consumption in this state shall be permitted an eight-percent variance above the allowable gross weight. Even with that variance, the 80,000-pound hard cap still applies.

Common Mistake: Overloading a trailer because the animals shifted during loading is a frequent inspection finding. Livestock weight is dynamic — animals move, and axle weights can change between the scale and the next weigh station. Always leave a buffer below the legal limit when loading live animals.

If your loaded rig genuinely cannot stay within legal limits, you will need an oversize or overweight permit before you move. Any load exceeding state law limits may not be moved over the highways of Arkansas without first obtaining a permit for such movement from the Department. Each such permit shall be carried in the vehicle to which it refers and shall be open to inspection by any law enforcement officer or authorized agent of the Department.

Violations carry financial consequences. Oversize and overweight fines in Arkansas start at $10 and rise with the unpermitted weight of the vehicle or load, from 3 to 5 cents per unpermitted pound. If an operator is caught exceeding the weight limits, they will be considered guilty of a minor offense. Upon their first conviction, they will have to pay a fine of up to $100. If convicted a second time within one year, the fine increases to a maximum of $200.

Ventilation, Flooring, and Animal Space Requirements in Arkansas

The physical condition of your trailer interior directly affects animal welfare during transport — and it is an area inspectors actively evaluate. While Arkansas does not publish a standalone livestock trailer welfare statute separate from federal standards, the state enforces federal animal welfare transport requirements and the Arkansas Livestock and Poultry Commission’s health regulations.

Adequate ventilation is a foundational requirement for any livestock trailer. Animals generate significant body heat, moisture, and ammonia during transport. A trailer without proper airflow can cause heat stress, respiratory distress, or death — especially during Arkansas’s hot and humid summers. Side vents, adjustable slats, and roof ventilation panels should all be in working order before you load.

Flooring integrity is equally critical. Trailer floors must be solid, free of holes, and capable of bearing the weight of the animals without flexing or breaking. Many haulers use rubber matting or grooved aluminum flooring to provide traction and reduce leg injuries. Slippery flooring causes animals to fall and injure themselves, and an inspector who finds damaged or inadequate flooring can pull your trailer out of service.

Pro Tip: Inspect your trailer floor from underneath before each haul. Rot, rust, and stress cracks in wooden or metal floors are not always visible from inside the trailer. A floor failure on the highway is both a safety catastrophe and a potential animal cruelty violation.

Animal space requirements are tied to species, size, and transport duration. The general principle under federal and state-level guidance is that animals must be able to stand in a natural position, maintain balance during transit, and not be so tightly packed that they cannot move enough to avoid injury. Overcrowding is a common citation during roadside inspections.

Bedding material — straw, wood shavings, or sand — is strongly recommended and in some cases required for certain species and haul durations. It absorbs waste, provides cushioning, and reduces leg fatigue. For longer hauls, plan stops for watering and feeding as required under federal twenty-eight-hour law, which limits the time livestock may be confined without rest, water, and feed to 28 consecutive hours.

Owners and operators of trucks and other conveyances shall not move any livestock into or within the State of Arkansas except in compliance with the provisions set forth in state regulations. That compliance obligation extends to the interior condition of your trailer on every trip.

CDL and Driver License Requirements for Hauling Livestock in Arkansas

Whether you need a Commercial Driver’s License to haul livestock in Arkansas depends on the weight of your rig, who owns the animals, and how far you are traveling. Getting this right matters — operating a commercial motor vehicle without the proper license is a serious violation.

Arkansas issues CDLs to drivers according to federal standards. A Class A CDL covers any combination of vehicles with a gross combination weight rating or gross combination weight of 26,001 pounds or more, inclusive of a towed unit with a gross vehicle weight rating or gross vehicle weight of more than 10,000 pounds. Most full-size livestock trailer combinations — a pickup and a loaded gooseneck or semi pulling a stock trailer — will exceed this threshold and require a Class A CDL.

A Class B CDL covers any single vehicle with a gross vehicle weight rating or gross vehicle weight of 26,001 pounds or more, or any such vehicle towing a vehicle with a GVWR that does not exceed 10,000 pounds. Smaller livestock hauling setups may fall into this category.

To apply for a CDL in Arkansas, you must meet baseline eligibility requirements. Drivers must be at least 18 years of age, or at least 21 years of age if they plan to drive outside of the state of Arkansas. You must have a valid regular driver’s license and have passed the medical and vision tests with supporting documentation.

Farmers and ranch operators hauling their own livestock may qualify for an important exemption. Section 32934 of MAP-21 provides a statutory exemption from most Federal Motor Carrier Safety Regulations, including those pertaining to commercial driver’s licenses and driver physical qualifications, for the operation of “covered farm vehicles” by farm and ranch operators, their employees, and certain other specified individuals under specific circumstances.

To qualify as a covered farm vehicle, your rig must meet specific criteria. The term “covered farm vehicle” includes any commercial motor vehicle traveling in the state in which the vehicle is registered or another state, operated by a farm or ranch owner or operator (or their employee or family member), and being used to transport to or from a farm or ranch agricultural commodities, livestock, or machinery or supplies. The vehicle must also be equipped with a special license plate or other state designation to allow for identification of the vehicle as a farm vehicle by law enforcement personnel.

If you do not fully qualify for the covered farm vehicle exemption but still haul livestock for agricultural purposes, you may be eligible for a Restricted CDL. Arkansas may, at its discretion, waive the required knowledge and skills tests and issue a restricted CDL to employees of designated farm-related service industries, including livestock feeders. However, restricted CDL holders may not operate a commercial motor vehicle beyond 150 miles from the place of business or the farm currently being served.

Key Insight: In Arkansas, harvest season has been defined as 365 days a year. Hours of service regulations shall not apply to drivers transporting agricultural commodities from the source within a 150 air-mile radius. This year-round exemption gives Arkansas livestock haulers more operational flexibility than drivers in most other states.

Understanding how Arkansas driver licensing rules interact with other Arkansas animal transport laws can help you build a complete picture of your compliance obligations as an animal owner or handler in the state.

Passing Roadside Inspections With a Livestock Trailer in Arkansas

Arkansas Highway Police conduct roadside inspections of commercial motor vehicles, including livestock trailers, on state highways and at weigh stations. Knowing what inspectors look for — and having everything in order before you roll — is the best strategy for getting back on the road quickly.

Inspections typically follow the North American Standard Inspection (NASI) protocols used across the country. Officers will evaluate the vehicle, the driver’s credentials, and the cargo. For livestock haulers, the cargo component includes both the trailer’s mechanical condition and the animals themselves.

What inspectors check on the vehicle:

• Brake system function and adjustment on both the towing vehicle and the trailer
• Lighting — all rear lights, brake lights, and turn signals operational
• Safety chain attachment and condition
• Tire condition, tread depth, and inflation
• Hitch and coupling integrity
• Trailer floor and structural soundness
• Ventilation openings unobstructed

What inspectors check on the driver:

• Valid driver’s license or CDL appropriate to the vehicle combination
• Medical certification if required
• Hours of service logs (unless exempt under the covered farm vehicle or agricultural exemption)
• Vehicle registration and farm plate affidavit if applicable

What inspectors check for the animals:

• Certificate of Veterinary Inspection (CVI) for interstate movements
• Entry permits for species that require them (swine, camelids, cervids, exotics, rodeo bulls)
• Animal identification — ear tags, brands, or other official ID
• Evidence of overcrowding or animal distress
• Trailer cleanliness and absence of disease indicators

Important Note: No animal that is affected with or recently exposed to any infectious, contagious, or communicable disease, or that originates from a quarantined area, shall be transported or moved into Arkansas until written permission is first obtained from the State Veterinarian. An inspector who identifies a sick or exposed animal in your trailer has the authority to quarantine the load on the spot.

Livestock and poultry moving into Arkansas found to be in non-compliance with Arkansas laws and regulations shall be quarantined to the nearest facility until all requirements are met. All costs related to non-compliance, including transport, testing, quarantine, or loss, are the responsibility of the owner or shipper. That financial exposure is a strong incentive to have every document and every piece of equipment squared away before you leave the farm.

To prepare for a smooth inspection, run through this pre-trip checklist every time you haul:

1. Verify trailer registration is current and the plate is secured to the rear
2. Confirm all lights, brakes, and safety chains are functional
3. Check the trailer floor, ventilation panels, and interior for damage
4. Gather CVIs, entry permits, and animal ID documentation for your load
5. Confirm your license class matches the weight of your combination
6. If using a farm plate exemption, have your qualifying affidavit in the cab
7. Verify your gross weight is within legal limits before leaving the property

If you haul multiple species or move animals regularly for shows and sales, it is worth bookmarking the Arkansas Department of Agriculture animal entry requirements page and the ARDOT farm vehicle regulations page so you always have access to the most current rules.

Arkansas livestock owners dealing with related regulatory questions may also find these resources helpful: rooster laws in Arkansas, Arkansas beekeeping laws, and Arkansas hunting laws for those who transport game animals after a hunt. For those curious about broader exotic animal transport rules, the United States laws on exotic pets resource provides a useful national overview.

Staying compliant with Arkansas livestock transport laws is not a one-time task — regulations are updated, permit rules change, and animal health requirements shift based on disease surveillance. Make it a habit to verify requirements with the Arkansas Department of Agriculture and the Arkansas Department of Transportation before every interstate haul, and consult the Arkansas DFA CDL office any time your vehicle combination changes.
