Transporting Livestock Laws in Utah: What Every Hauler Needs to Know
June 18, 2026
Moving cattle, horses, sheep, or any other livestock across Utah roads is not as simple as loading up and hitting the highway. The state enforces a layered set of rules that cover your trailer’s registration, its physical condition, the documents you carry, and even the license in your wallet — and officers can check all of it at any weigh station or roadside stop.
Whether you haul your own animals a few miles between pastures or run livestock commercially across county lines, understanding Utah’s transporting livestock laws keeps you legal, protects your animals, and helps you avoid costly fines or delays at inspection points. This guide walks through every major requirement so you can load up with confidence.
Livestock Trailer Registration and Identification Requirements in Utah
Before your trailer ever leaves the property, it must be properly registered and documented. Utah treats livestock trailers as standard motor vehicles for registration purposes, meaning they must carry valid plates issued by the Utah Division of Motor Vehicles.
Utah law does offer a useful option for commercial operators. Effective January 1, 2026, Utah Code § 41-1a-228 allows the owner of a trailer or semitrailer used as a commercial vehicle to obtain an alternative special registration and lifetime license plate valid for the life of the trailer while the trailer is possessed by the registrant. This eliminates annual renewal hassle for qualifying commercial livestock haulers. Owners of intrastate commercial trailers that are not travel trailers may also obtain this alternative special lifetime registration and plate.
Beyond the trailer itself, the animals inside require their own documentation. Utah is a brand inspection state, and those requirements follow you onto the road.
- Cattle and horses leaving the state: Brand inspections are required by law, even if cattle or horses are not branded, when leaving the state. A 72-hour travel inspection costs $20.00 one-way for up to 10 head, then $2.00 per head after the first 10.
- Lifetime travel permits for horses: A lifetime travel permit is honored in all states and Canada for the lifetime of the horse, and costs $40.00 per head.
- Intrastate travel proof of ownership: When traveling within the state, always carry proof of ownership. Acceptable items include a wallet-size brand card matching the brand on the cattle or horse, or a brand inspection certificate or auction invoice showing where you purchased the animal — but a bill of sale alone will not be accepted as proof of ownership.
- Hauling someone else’s animals: When you are transporting cattle or horses that belong to someone else, carry written permission from the owner.
- Scheduling inspections: Call your local brand inspector at least 24 hours in advance to schedule an inspection, as brand inspections are conducted only during daylight hours.
Pro Tip: Livestock inspectors are located in all of Utah’s 29 counties, so finding one near your operation should not be difficult. Plan your inspection appointment at least a day ahead to avoid last-minute delays on moving day.
For cattle moving between brand inspection districts within Utah, cattle or calves may be transported between brand inspection districts without brand inspection if they are destined for a livestock market in this state. However, horses and mules may move within the state without a brand inspection, but a brand inspection is required on a change of ownership or to leave this state.
Owners and operators of trucks or other conveyances used for the transportation of livestock are responsible for ensuring each consignment is prepared for shipment in keeping with state and federal laws and regulations. Certificates of Veterinary Inspection, brand certificates, and permits should be attached to the waybill accompanying the attendant in charge of the animals.

Structural and Safety Standards for Livestock Trailers in Utah
A registered trailer is not automatically a legal trailer. Utah requires that livestock trailers meet basic structural and safety standards before they operate on public roads. These standards protect both the animals inside and other motorists sharing the highway.
Lighting and connection hardware are among the most frequently checked items during roadside stops. Trailers must have functional lights and reflectors that meet state standards, including brake lights, turn signals, and taillights that must be visible from the rear of the trailer.
Safety chains are mandatory. Safety chains are required to connect the trailer to the towing vehicle, and they must be crossed beneath the trailer’s tongue to prevent the trailer from detaching in the event of a hitch failure.
Braking systems are another critical requirement. Trailers above certain weight thresholds must have independent braking systems that function correctly when the trailer is loaded. A fully loaded livestock trailer carrying cattle or horses can reach tens of thousands of pounds — a failed brake system at highway speed is catastrophic.
Important Note: Utah Code § 41-6a-1706 states that a person may not occupy a trailer or semitrailer while it is being drawn by a motor vehicle on a public highway. Livestock trailers used in an agricultural operation are exempt from this rule for animals, but passengers riding in the trailer bed remain prohibited.
Structural integrity of the trailer body itself also matters. Panels, gates, and latches must be strong enough to contain animals under load and during sudden stops or turns. Loose or broken gates that allow animals to escape during transport can result in citations and liability for accidents caused by animals on the roadway. For context on how Utah handles animal-related road incidents, the state’s roadkill laws in Utah outline responsibilities when livestock ends up on public roads.
Before every trip, run through a structured pre-departure check. Before starting your trip, conduct a thorough inspection of your trailer and towing vehicle, checking tire pressure, lights, brakes, and connections to ensure everything is in good working condition.
Size, Weight, and Load Limits for Livestock Trailers in Utah
Utah sets clear dimensional and weight limits for vehicles operating on its highways. Exceeding those limits without a permit is a violation that can result in fines and forced off-loading — neither of which you want when you’re hauling live animals.
The standard legal dimensions for any trailer operating on Utah highways without a special permit are as follows:
| Dimension | Maximum Allowed (No Permit) |
|---|---|
| Height | 14 feet |
| Width | 8 feet 6 inches |
| Straight truck length | 45 feet |
| Straight truck and trailer combined | 65 feet |
Under Utah Admin. Code R909-2-4, the legal size vehicle dimensions that may be operated without special permits on Utah highways are a height of 14 feet and a width of 8 feet 6 inches. For tractor-semitrailer combinations, there is no length limit on the National Network or supplemental highways.
Weight limits are equally important. A driver must obtain a commercial driver’s license to operate any vehicle used in commerce to transport passengers or property that has a gross vehicle weight rating of 26,001 pounds or more, or a gross combination weight rating of 26,001 pounds or more with a towed unit that has a gross weight rating of 10,001 pounds or more.
Utah does allow heavier loads under permit. Long combination vehicles are allowed in Utah up to 129,000 lbs, and other vehicles can obtain overweight permits to these weights as well, assuming compliance with the federal bridge formula.
Pro Tip: Utah’s weigh scales double as ports of entry. Any motor vehicle carrying livestock must stop and report at weigh scale locations, regardless of gross vehicle weight. Plan your route to account for these mandatory stops, especially on interstate corridors.
Agricultural operations do receive some accommodation under Utah’s size and weight rules. Utah Admin. Code R909-2-30 addresses farmers, implements of husbandry, and agricultural operations, including specific provisions for hay truck operations that may transport two rolls or bales of hay side by side when the combined width does not exceed 10 feet. Check with the Utah Department of Transportation (UDOT) to confirm whether your specific agricultural hauling configuration qualifies for any exemptions before your trip.
Ventilation, Flooring, and Animal Space Requirements in Utah
Utah’s livestock transportation rules are not limited to the trailer’s mechanical condition — they also address the welfare of the animals inside. Adequate ventilation, safe flooring, and sufficient space are all part of hauling livestock legally and responsibly.
Ventilation is essential for animal health during transport, particularly in Utah’s climate, which swings from high-altitude cold to intense summer desert heat. Trailers must allow adequate airflow to prevent heat stress, respiratory distress, and dehydration during transit. Solid-sided trailers without ventilation openings are generally not appropriate for livestock in warm conditions.
Flooring requirements are driven by animal safety. Livestock trailers must have non-slip flooring surfaces to prevent animals from falling or injuring themselves during acceleration, braking, or cornering. Rubber mats, grooved metal, or treated wood flooring are common compliant options. Flooring must also be structurally sound — rotted wood or cracked metal grating that could give way under an animal’s weight is a clear violation.
Common Mistake: Many haulers overlook flooring condition during routine maintenance. Inspect trailer floors from underneath at least once per season, especially at the edges and corners where moisture collects and rot or corrosion begins.
Animal space requirements are tied to federal standards under the Twenty-Eight Hour Law for interstate hauls, which requires that animals transported across state lines be unloaded, fed, watered, and rested for at least five consecutive hours after 28 consecutive hours of confinement. Utah’s intrastate rules reinforce humane handling principles consistent with federal guidelines.
Overcrowding is a practical and legal concern. Packing animals too tightly increases injury risk and can constitute animal cruelty under Utah Code Title 76. Each species has different space needs — cattle require more room than sheep or goats, and horses need space to balance themselves during transit. As a general guide, allow enough floor space for each animal to stand naturally and shift its weight without being pinned against the trailer wall.
Water and feed access during long hauls also fall under humane transport obligations. For interstate movements, inspection and proper identification are essential for livestock traceability — if an animal is transported to a different geographical area and later displays clinical signs of a reportable disease, the prior location can be traced to inform health officials of the potential of an outbreak in that area. This traceability system depends on animals arriving healthy, which means proper care during transport is both a legal and a public health obligation.
Utah’s animal welfare framework extends beyond livestock transport. If you raise or keep animals in Utah, it is worth reviewing related state rules, such as backyard chicken laws in Utah and beekeeping laws in Utah, to understand how the state approaches animal care across different contexts.
CDL and Driver License Requirements for Hauling Livestock in Utah
The license you need to legally haul livestock in Utah depends on the weight of your rig and whether you are operating commercially. Getting this wrong is one of the most common — and expensive — compliance errors livestock haulers make.
For lighter personal-use hauls, a standard license may be sufficient. In Utah, if you are towing a trailer, you must have a valid driver’s license. For most standard trailers, a regular Class D license is sufficient. However, if you are towing a trailer that exceeds specific weight limits, you may need a special endorsement or a Class A CDL.
The CDL threshold is clearly defined under Utah law. A driver must obtain a CDL to operate any vehicle used in commerce to transport passengers or property that has a gross vehicle weight rating of 26,001 pounds or more, or a gross combination weight rating of 26,001 pounds or more with a towed unit that has a gross weight rating of 10,001 pounds or more.
CDL classes break down as follows for livestock haulers:
- Class A CDL: Authorizes operation of any combination of vehicles with a gross combination weight rating of 26,001 pounds or more where the gross vehicle weight rating of the vehicle or vehicles being towed is over 10,000 pounds. This is the license most commercial livestock haulers need.
- Class B CDL: Covers straight trucks over 26,001 lbs not towing a heavy trailer — less common for livestock hauling but applicable to some configurations.
- Class C CDL: Covers vehicles carrying hazardous materials or more than 15 passengers — generally not the primary CDL class for livestock transport.
To earn a CDL in Utah, drivers must meet specific requirements, including having held a regular Class D Utah driver’s license for at least one year. Applicants must pass one or more written knowledge tests depending on the type of CDL and endorsements being applied for, pass a vehicle skills test to show the ability to inspect and safely control a commercial vehicle, and pass road skills tests to demonstrate the ability to safely operate a commercial vehicle in various on-road situations in Utah.
Key Insight: The agricultural exemption from CDL requirements applies in some states, but Utah’s exemption is narrow. Farm operators transporting their own livestock in their own vehicles between their own properties may qualify for limited exemptions, but any for-hire hauling or operation of vehicles above the weight threshold in commerce requires a proper CDL. Verify your situation with the Utah Driver License Division before assuming an exemption applies.
Commercial livestock haulers must also comply with federal hours-of-service regulations. Drivers may not drive for more than 11 hours after coming on duty following an off-duty period of at least 10 consecutive hours, may not drive past the 14th hour after coming on duty, and must take a break of at least 30 minutes after driving for eight consecutive hours. These limits apply to interstate commercial operations and are enforced at Utah’s ports of entry.
Understanding driver licensing requirements across state lines is also important if your livestock hauls cross into neighboring states. You can compare Utah’s framework against Arizona animal transport rules or review how other western states handle similar regulations.
Passing Roadside Inspections With a Livestock Trailer in Utah
Utah’s weigh stations are also ports of entry, and livestock haulers are required to stop at them regardless of vehicle weight. Knowing what inspectors look for — and having everything ready before you pull in — is the difference between a quick clearance and a costly delay.
The mandatory stop requirement is unambiguous. In Utah, any motor vehicle carrying livestock must stop and report at weigh scale locations, regardless of gross vehicle weight or gross combination weight. Do not attempt to bypass a weigh station when hauling live animals.
Inspectors at Utah ports of entry check a combination of vehicle compliance, driver credentials, and animal documentation. Here is what you should have organized and ready:
- Driver’s license or CDL — appropriate class for your vehicle combination
- Vehicle registration — current and matching the trailer on the road
- Brand inspection certificate or proof of ownership — the owner or transporter must have an official Brand Inspection Certificate or other acceptable proof of ownership in their possession
- Written owner permission — if hauling animals belonging to someone else
- Certificate of Veterinary Inspection (CVI) — required for interstate movements and certain intrastate movements involving disease-risk animals
- Weight ticket — vehicles that obtain by-pass privileges must have a weight ticket from a scale certified by the Department of Agriculture available for inspection by law enforcement
Inspectors will also conduct a visual check of the trailer itself. Authorities may conduct roadside inspections to ensure that trailers meet safety and legal standards, and being prepared can help you avoid any issues during these checks. This includes verifying lights, safety chains, brakes, and structural integrity of the trailer body.
Pro Tip: Regular vehicle inspections, staying informed about regulation changes, and obtaining necessary permits in advance are key strategies for compliance. Keep a dedicated document folder in your cab with all required paperwork so you are not scrambling at the scale.
For interstate hauls, animal health documentation becomes even more critical. Any horses or livestock entering Utah from a county where Vesicular Stomatitis has been diagnosed within the last 14 days, or a county that contains a premises quarantined from Vesicular Stomatitis, must be accompanied by a certificate of veterinary inspection issued within 14 days of entry confirming the animals are free from clinical signs of the disease.
Disease testing requirements vary by species. All sexually intact cattle over 18 months of age moving across state lines must be officially identified and accompanied by an approved document with official ID numbers. Cattle and bison of any age used for rodeo, recreational events, shows, and exhibitions must be officially identified. Additional testing for diseases such as Tuberculosis, Brucellosis, and Trichomoniasis may be required by the destination state.
For horses entering Utah from out of state, a horse must have a negative EIA (ELISA or Coggins-AGID) test within the last 12 months. EIA is an infectious disease spread via mosquitoes, biting flies, and dirty needles. The test is performed by a licensed and USDA-accredited veterinarian who draws the blood and sends it to an approved laboratory, which takes several days — so consulting with your veterinarian and planning ahead prior to transportation is necessary to avoid unwanted delays.
Violations discovered during roadside inspections carry real consequences. Failing to comply with Utah’s towing laws can result in fines or penalties, and law enforcement may issue citations for violations such as improper hitching, inadequate lighting, or overloading. Serious violations — particularly those involving falsified animal health documents — can result in license suspension or revocation of operating authority for commercial carriers.
Utah’s broader animal law landscape is worth understanding if you work with livestock regularly.

Staying compliant with Utah’s transporting livestock laws comes down to preparation. Register your trailer correctly, maintain it to structural and safety standards, carry every required document, load your animals humanely, know which license your rig requires, and stop at every weigh station when livestock are on board. Do those things consistently, and your roadside inspections become routine clearances rather than stressful surprises. For the most current requirements, always verify with the Utah Department of Agriculture and Food and the USDA APHIS interstate movement guidelines before any significant haul.
