Transporting Livestock Laws in Texas: What Every Hauler Needs to Know
June 20, 2026
Texas moves more livestock than nearly any other state in the country, and with that volume comes a detailed set of rules governing how animals are transported on public roads. Whether you are hauling a few goats to a sale barn or moving a full load of cattle across the state, getting it wrong can mean fines, quarantined animals, or a failed roadside inspection that puts your entire operation on hold.
This guide walks you through every major legal requirement for transporting livestock in Texas — from trailer registration and movement permits to CDL thresholds and what inspectors look for when they pull you over. Knowing these rules before you load up is far easier than dealing with the consequences after the fact.
Livestock Trailer Registration and Identification Requirements in Texas
Before your trailer ever touches a public road with animals aboard, you need to make sure it is properly registered and that you have the correct movement documentation in hand. Texas law treats these two requirements as equally important, and officers can check both at any time.
Trailer titling and registration in Texas depends primarily on weight. Titling is optional for all newly assembled trailers with a gross weight of 4,000 pounds or less, and newly assembled farm trailers with a gross weight of 34,000 pounds or less. For heavier trailers, a full title and registration through the Texas Department of Motor Vehicles (TxDMV) is required.
A farmer or rancher who owns a farm trailer or farm semitrailer may obtain a distinguishing Farm Trailer license plate for a $5 fee under certain conditions, provided the trailer or semitrailer only transports qualifying agricultural goods. A vehicle owner may obtain a “FARM TRAILER” license plate for a farm trailer or farm semitrailer with a gross weight of more than 4,000 pounds but not more than 34,000 pounds, and the fee for that plate is $5.00 per year.
Farm Trailer license plates may only be used on farm trailers and farm semitrailers used exclusively to transport seasonally harvested agricultural products or livestock from the place of production to the place of processing, market, or storage, or farm supplies from the place of loading to the farm. If you use your trailer for anything outside those purposes — including hauling animals to competitions or rodeos — the farm plate exemption no longer applies.
Important Note: A horse trailer with sleeping quarters does not qualify for a farm trailer tax exemption, and any trailer used for transporting horses to and from competitions or shows is also excluded from that exemption under Texas Comptroller rules.
Movement permits and documentation are a separate but equally critical requirement. A person who drives a vehicle, including a truck or an automobile, containing livestock, domestic fowl, slaughtered livestock or domestic fowl, or butchered portions of livestock or domestic fowl on a highway, public street, or thoroughfare or on property owned or leased by a person other than the driver must obtain a permit authorizing the movement.
A permit must be signed by the owner or caretaker of the shipment or by the owner or person in control of the land from which the driver began movement, and must state the point of origin of the shipment, the point of destination, and the number of living or slaughtered animals. Keep this document with you throughout the trip — it is one of the first things an officer will request.
For interstate movement, health documentation requirements are stricter. As of January 1, 2026, all import certificates of veterinary inspection (CVIs) must be electronic. If you are bringing animals into Texas from another state, make sure your veterinarian is using an approved electronic CVI platform before loading day. You can also review pet import laws in Texas for additional context on how the state handles incoming animal documentation across species.
Title 4, Part 2 of the Texas Administrative Code requires cattle, swine, sheep, and goats transported for sale or exhibition to meet health certification requirements, including official identification and negative disease test results. Contact the Texas Animal Health Commission (TAHC) or call their Permits Help Desk at 512-719-0777 to confirm current requirements for your specific species before transport.
Structural and Safety Standards for Livestock Trailers in Texas
A livestock trailer that is mechanically sound protects your animals, other drivers, and your liability exposure. Texas enforces both state-level structural standards and federal safety requirements for trailers used in commercial operations.
Trucking companies are required to conduct intense and extensive inspections of all their trailers and trucks at least once per year, and these inspections must include all items listed in the Minimum Periodic Inspection Standards, covering checks on the brake system, coupling devices, the exhaust system, and the fuel system, plus a litany of other truck and trailer functions.
Truck drivers must also inspect their own vehicles and ensure that the truck and trailer can be safely driven before they begin their trip, and they are instructed to complete a post-trip vehicle report listing any issues or defects that may affect safe operation. For livestock haulers, this pre-trip check is especially important because structural failures — broken floor boards, failed latches, or damaged ramps — can injure animals and create serious road hazards.
Key structural elements inspectors look for on livestock trailers include:
- Functional brake systems on all axles (required on trailers above certain weight thresholds)
- Secure coupling devices, including safety chains or cables
- Working running lights, brake lights, and turn signals
- Intact side walls and gates with no sharp protrusions that could injure animals
- Properly functioning loading ramp or tailgate
- Exhaust routed away from the animal compartment
Pro Tip: Walk your trailer before every haul and document any repairs. A written maintenance log can work in your favor during a roadside inspection dispute and demonstrates good-faith compliance.
A farm trailer or farm semitrailer with a “FARM TRAILER” license plate is exempt from the state inspection certificate requirements. However, that exemption does not mean the trailer is exempt from being in safe operating condition. Officers can still place an out-of-service order on a trailer they deem unsafe, regardless of plate type.
Size, Weight, and Load Limits for Livestock Trailers in Texas
Overweight and oversized loads are one of the most common compliance failures for livestock haulers. Texas enforces both federal and state weight limits, and the consequences for violations — including fines and mandatory off-loading — can be severe.
A truck and trailer, along with its fully loaded cargo, cannot surpass a weight of 80,000 pounds. This federal gross vehicle weight limit applies on interstate highways and is mirrored in Texas state law for most roadways. The Texas Department of Motor Vehicles enforces strict Texas truck weight limits to promote road safety and protect road surfaces from damage caused by heavy commercial vehicles, and trucks may generally carry a gross vehicle weight of up to 80,000 pounds on highways.
Beyond gross weight, axle weight limits also apply. The standard breakdown for most Texas roadways is:
| Axle Configuration | Maximum Weight |
|---|---|
| Single axle | 20,000 lbs |
| Tandem axle group | 34,000 lbs |
| Gross vehicle weight (combined) | 80,000 lbs |
The TxDMV may also issue oversize or overweight permits for specific loads, and these permits outline the approved route, allowable weight, and travel times to help reduce roadway stress and traffic hazards. If your loaded livestock trailer regularly exceeds standard limits, applying for a permit in advance is far preferable to being stopped at a weigh station.
Speed limits also apply specifically to commercial configurations. In the state of Texas, all large commercial vehicles must sustain a maximum of 70 mph during the day and 65 mph at night. When hauling livestock, driving at or below these limits also reduces animal stress and the risk of injury during transport.
Common Mistake: Many livestock haulers load animals without accounting for the combined weight of the trailer, towing vehicle, feed, water, and animals together. Weigh your fully loaded rig before departure — not just the trailer alone.
For load distribution, trucking companies are held to strict standards on how cargo can be loaded and secured, and these regulations include the types of tie-downs available for use and which person is responsible for checking the security of the load before the truck and driver are given the all-clear. While live animals cannot be strapped down, proper pen dividers, gate latches, and density management serve the same function of preventing load shift.
Ventilation, Flooring, and Animal Space Requirements in Texas
Texas does not have a single standalone statute that sets minimum square footage per animal for road transport, but state and federal animal welfare standards — combined with anti-cruelty laws — establish a clear floor for what is acceptable. Hauling animals in overcrowded, poorly ventilated, or dangerous conditions exposes you to both civil and criminal liability.
You could face fines up to $1,000 if you transport livestock without proper documentation, and more serious violations — like transporting animals in inhumane conditions — can bring even steeper penalties. For longer hauls, federal rules under the Twenty-Eight Hour Law also require that animals transported by motor vehicle in interstate commerce must be unloaded, fed, watered, and rested after 28 consecutive hours of confinement.
Practical ventilation and flooring standards that align with Texas and federal expectations include:
- Ventilation: Side vents or slats must allow adequate airflow at all times; enclosed metal trailers with no ventilation are not acceptable for live animals
- Flooring: Non-slip surfaces such as rubber mats, expanded metal, or grooved aluminum help prevent falls and leg injuries during transit
- Drainage: Floors should allow urine and liquid to drain to reduce slip hazards and ammonia buildup
- Space density: Animals must have enough room to stand in a natural position and maintain balance; overcrowding that causes animals to fall is a welfare violation
- Bedding: Recommended for swine, sheep, and young animals, especially in cold weather or on long hauls
Key Insight: The TAHC and USDA both have authority to investigate inhumane transport conditions. A complaint from a weigh station officer or another driver can trigger an inspection of your operation well beyond the initial stop.
Texas animal cruelty law reinforces these standards. Animal cruelty in Texas is serious business, and intentionally causing pain or injury to an animal is a criminal offense. Transport conditions that result in preventable injury or death — such as extreme heat exposure in a sealed trailer — can be prosecuted under these statutes. Reviewing pet laws in Texas can give you broader context on how the state approaches animal welfare obligations for all species. For species-specific concerns, goat ownership laws in Texas and backyard pig laws in Texas cover welfare standards relevant to common livestock species.
CDL and Driver License Requirements for Hauling Livestock in Texas
One of the most misunderstood areas of livestock transport law is when a commercial driver’s license is actually required. The answer depends on the weight of your rig, whether you are operating commercially, and whether you cross state lines.
The CDL threshold is based on gross combination weight rating (GCWR). If the GCWR of your tow vehicle is greater than 26,000 pounds and whatever you are towing has a total GVWR of more than 10,000 pounds, then you need a Class A CDL to operate that tow vehicle, whether that vehicle is a car, truck, or tractor.
Texas follows federal CDL classifications established by the FMCSA. The three primary CDL classes are: Class A — required to operate combination vehicles with a GCWR of 26,001 pounds or more, provided the towed unit exceeds 10,000 pounds; Class B — required for single vehicles with a GVWR of 26,001 pounds or more, or a vehicle towing a unit weighing 10,000 pounds or less; and Class C — required for vehicles designed to transport 16 or more passengers or hazardous materials requiring placards.
| CDL Class | When Required for Livestock Haulers |
|---|---|
| Class A | GCWR over 26,000 lbs AND trailer GVWR over 10,000 lbs |
| Class B | Single vehicle GVWR over 26,000 lbs, trailer under 10,000 lbs |
| Non-CDL Class A or B | Agricultural exemption applies — farm use, not for-hire |
| Standard license | Light trailer combinations under CDL thresholds |
The agricultural exemption is critically important for many ranchers and farmers. Some commercial vehicles, based upon their gross vehicle weight rating, may not require the driver to hold a CDL, and drivers of these vehicles need to hold a Class A or B non-commercial driver’s license. This applies to vehicles used to transport agricultural commodities, livestock, machinery, or supplies to or from a farm or ranch, provided they are not used in for-hire motor carrier operations.
However, the line between personal agricultural use and commercial hauling is not always clear. To qualify as a commercial motor vehicle requiring a CDL, the vehicle must be used in “commerce,” which the FMCSA defines broadly as any trade, traffic, or transportation between points in one state and another, or any trade, traffic, or transportation that affects trade, traffic, or transportation in the U.S. If you are hauling someone else’s cattle for pay, that is commercial operation — and the CDL requirement applies regardless of exemption claims.
In Texas, you must be at least 18 years old for an intrastate commercial driver’s license and 21 for an interstate commercial driver’s license. If your livestock hauls regularly cross state lines, the 21-year minimum age and interstate CDL requirements apply to every driver in your operation.

Passing Roadside Inspections With a Livestock Trailer in Texas
Roadside inspections of livestock trailers are conducted by Texas Department of Public Safety (DPS) Commercial Vehicle Enforcement officers, and they follow a structured process. Knowing what inspectors check — and having everything in order before you pull out — is the best way to get back on the road quickly.
What officers check during a livestock trailer inspection:
- Driver documentation: Valid driver’s license or CDL (appropriate class), medical examiner’s certificate if CDL is required, hours-of-service logs if applicable
- Vehicle registration and permits: Current registration, farm trailer plate eligibility, movement permit for the livestock on board
- Animal health documents: Certificate of Veterinary Inspection (CVI) for applicable species, entry permits for animals coming from out of state, official animal identification (ear tags, brands)
- Trailer mechanical condition: Brakes, lights, coupling devices, tires, and structural integrity
- Load condition: Animal welfare, ventilation, flooring condition, and evidence of inhumane treatment
The Texas Animal Health Commission regulates the entry of many livestock, poultry, and exotic livestock species into the state, and state and federal rules regarding animal movement, travel, entry and show requirements, and international import and export can be complex and involve more than one government agency. During an inspection, officers may contact TAHC directly to verify documentation, so make sure your paperwork matches your actual load.
Species-specific identification is a frequent inspection focus. Title 4, Part 2 of the Texas Administrative Code requires cattle, swine, sheep, and goats transported for sale or exhibition to meet health certification requirements, including official identification and negative disease test results. Animals without proper identification can be held at the inspection point until documentation is produced.
Pro Tip: Keep a dedicated transport folder in your cab that contains your movement permit, CVI, animal ID records, trailer registration, and your driver’s license or CDL. Inspectors appreciate organized documentation and it speeds up the process significantly.
For equine specifically, Texas requires all equine entering Texas to obtain a valid certificate of veterinary inspection (CVI) and EIA test (Coggins) prior to entry. This requirement applies even for horses moving from another state into Texas for a temporary event. Failing to carry these documents during a roadside stop can result in the animals being turned back at the border or held pending veterinary clearance.
If an inspector places your trailer out of service, you cannot legally move it until the deficiencies are corrected. Trucking companies are required to conduct inspections of all their trailers and trucks at least once per year, covering all items listed in the Minimum Periodic Inspection Standards. Staying ahead of this requirement with documented annual inspections dramatically reduces the risk of an out-of-service order during a roadside check.
Penalties for non-compliance are real. Texas enforces strict penalties for violations of agricultural laws, ranging from administrative fines to criminal charges, and the severity depends on the nature of the violation, such as failing to meet livestock health requirements. Beyond fines, a pattern of violations can trigger enhanced scrutiny of your entire operation by both TAHC and DPS.
Understanding Texas animal laws more broadly helps you stay compliant across every aspect of livestock ownership and transport. Resources like roadkill laws in Texas, rooster crowing laws in Texas, and leash laws in Texas cover the wider landscape of animal regulations that Texas livestock owners regularly encounter.
