Transporting Livestock in Minnesota: Rules Every Hauler Needs to Know

Hauling cattle, hogs, horses, or sheep across Minnesota roads is not as simple as loading up and hitting the highway. State law imposes specific rules on trailer registration, structural standards, size and weight limits, animal welfare conditions, driver licensing, and roadside compliance — and getting any one of them wrong can mean fines, an out-of-service order, or worse, injured animals.

Whether you are a farmer moving your own stock to market, a commercial carrier hauling for hire, or a hobby producer trailering a few animals to a show, Minnesota’s transporting livestock laws apply to you in different ways depending on how, why, and how far you drive. This guide breaks down each layer of the law so you can plan every trip with confidence.

Livestock Trailer Registration and Identification Requirements in Minnesota

The first question most livestock owners ask is whether their trailer needs to be registered at all. The answer depends on the trailer’s weight and how it is used.

Small farm trailer exemption. Minnesota registration is not required if your livestock trailer meets the definition of a small farm trailer — a farm trailer with a gross weight of less than 10,000 pounds that is drawn by a qualifying farm vehicle and not used for commercial hire. If your trailer falls under that threshold and meets all other statutory conditions, it is exempt from standard motor vehicle registration taxes and does not need license plates.

Trailers above 10,000 lbs. Once your loaded trailer crosses the 10,000-pound gross weight threshold, standard registration rules apply and you will need plates. At that point, the trailer must be registered through the Minnesota Driver and Vehicle Services (DVS) office, and the registration documents must be available in the vehicle during transport.

Farm truck classification. A “farm truck” under Minnesota law means all single-unit trucks, truck-tractors, tractors, semitrailers, and trailers used by the owner to transport agricultural, horticultural, dairy, and other farm products, including livestock, produced or finished by the owner, from the farm to market, and to transport property and supplies to the farm. Vehicles registered in this class carry different fee structures and operational permissions than commercial trucks.

USDOT number and carrier identification. If you operate only in Minnesota and the vehicle’s or combination’s gross vehicle weight (GVW) is greater than 10,000 pounds, the carrier must have a USDOT number, and that number must be displayed on the power unit in addition to the carrier name. For interstate operators, the same display requirement applies but the threshold for commercial motor vehicle classification also triggers additional federal rules.

Pro Tip: Keep a printed copy of your registration documents, farm truck classification paperwork, and any USDOT self-designation forms in the cab at all times. Officers at roadside inspections will ask to see them, and a missing document can trigger a compliance review even when your equipment is otherwise legal.

Covered Farm Vehicle (CFV) self-designation. Vehicles that transport agricultural commodities, livestock, machinery, or supplies to or from a farm — and that meet gross weight and operational radius requirements — may qualify as a Covered Farm Vehicle. Vehicles displaying Minnesota apportioned, truck class, or passenger class license plates, and meeting all other qualifications, may complete, print, and carry a CFV self-designation form, which must be carried in the vehicle and displayed upon demand by enforcement personnel.

If you also move animals into or out of Minnesota, note that it is unlawful for the owner or the person having custody or control of domestic animals subject to a quarantine to remove any of them from their first location within the state after interstate shipment or transportation is completed until they are released by authority of the Minnesota Board of Animal Health. Always confirm disease status and movement clearance before crossing state lines. You can learn more about disease-related movement rules in our guide on brucellosis laws in Minnesota.

Structural and Safety Standards for Livestock Trailers in Minnesota

Minnesota does not operate in isolation — commercial livestock trailers operating on public roads are subject to both state vehicle safety statutes and federal motor carrier safety regulations (FMCSRs) when the vehicle qualifies as a commercial motor vehicle. Structurally, your trailer must be roadworthy, properly lit, and equipped with functioning safety systems before you leave the driveway.

Brakes. If a trailer has an empty weight of over 3,000 pounds, it must be equipped with working brakes. All trailer brake systems must ensure the vehicle can stop within 40 feet at 20 mph. For heavier livestock loads, you should also test your brake controller settings before each trip, since the correct gain setting changes with load weight.

Safety chains and breakaway systems. Trailers with a GVW or GVWR of 3,000 pounds or more are required by Minnesota state law to meet specific safety equipment standards. You should attach tethers in a break-away system directly to the towing unit, not to the chains or hitch itself. Minnesota law requires safety chains adequate to hold the vehicle.

Lighting and load markers. Combinations of vehicles must be equipped with sufficient clearance markers, or lamps for night transportation, on both sides and upon the extreme ends of a projecting load to clearly mark the dimensions of the load. For livestock trailers operating at dusk or after dark, all marker lights, taillights, and brake lights must be fully functional.

Important Note: Federal motor carrier regulations under 49 CFR Parts 390-397 apply to commercial livestock operations in Minnesota. If your rig qualifies as a commercial motor vehicle, annual vehicle inspections, driver qualification files, and vehicle condition reports are mandatory — not optional.

Annual inspection requirement. Transport vehicles must show proof of an annual inspection performed by a Minnesota Certified Inspector. This applies to commercial motor vehicles. Keep the inspection report on board — roadside officers will ask for it. If you haul livestock commercially, treat the annual inspection as a non-negotiable calendar item, not an afterthought.

Loading chute trailers. A livestock or poultry truck owned or operated by a livestock or poultry carrier and used primarily for transporting livestock or poultry for hire may draw one additional two-wheel trailer, the loaded weight of which does not exceed 3,000 pounds, for the sole purpose of transporting a livestock or poultry loading chute. That two-wheel chute trailer is classified as special mobile equipment under Minnesota law. Note that this provision does not apply to the seven-county metropolitan area.

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

Minnesota enforces strict dimensional and weight limits on all vehicles, and livestock trailers are not exempt. Exceeding these limits without a permit exposes you to civil weight penalties and potential out-of-service orders.

Standard weight limits. Minnesota weight regulations limit gross vehicle weight (GVW) to 80,000 pounds. Single axles cannot bear a weight greater than 20,000 pounds, with tandem axles limited to 34,000 pounds. These limits apply on Interstate highways, U.S. highways, and MN State Trunk Highways.

County roads and local streets. All other streets and county roads within the state carry a 9-ton axle weight limit. If your route takes you off the trunk highway system to reach a farm or sale barn, plan your axle weights accordingly — the lower county road limit can catch haulers off guard.

Livestock hauler special weight allowance. Minnesota allows a vehicle or combination of vehicles with six or more axles while exclusively engaged in transporting livestock to operate with a gross vehicle weight of up to 88,000 pounds. This is a significant allowance for larger commercial livestock rigs, but it requires the vehicle to be exclusively transporting livestock — mixed loads do not qualify. No interstate travel is permitted under this allowance.

Weight Category	Limit	Notes
Standard GVW (all vehicles)	80,000 lbs	Applies on trunk highways and interstates
Single axle	20,000 lbs	Standard limit statewide
Tandem axle	34,000 lbs	Standard limit statewide
County roads / local streets	9-ton axle limit	Lower than trunk highway limit
Livestock hauler (6+ axles, livestock only)	88,000 lbs	No interstate travel; no mixed loads

Dimensional limits. Minnesota limits the length of a semi-trailer to 53 feet. Trailer combinations are limited to twin doubles, with each trailer not exceeding 28 feet 6 inches in length. The width of vehicles is limited to 102 inches, with the total height not to exceed 13 feet 6 inches.

Overall combination length. Statewide, except on highways identified under special provisions, no combination of vehicles may exceed a total length of 75 feet. Livestock carriers operating on four-lane divided highways may access additional route flexibility for terminal access, but must still respect the 75-foot limit on other roads.

Oversize/overweight permits. To obtain an oversize or overweight permit, the road authority over whose roadway you wish to travel must issue the permit. For Interstate or State Trunk Highways, the road authority is MnDOT. If your loaded livestock trailer exceeds any standard limit, apply for the appropriate permit before departure — not after you are flagged at a weigh station.

Common Mistake: Many livestock haulers assume the 88,000-pound special allowance applies to their operation automatically. It does not — it requires six or more axles, exclusively livestock cargo, and no interstate travel. A mixed load of livestock and feed, for example, disqualifies you from the allowance entirely.

Ventilation, Flooring, and Animal Space Requirements in Minnesota

Minnesota does not have a standalone state livestock transport welfare statute that specifies square footage per animal or precise ventilation dimensions for trailer interiors. However, federal standards under the Twenty-Eight Hour Law, FMCSA regulations, and general animal cruelty statutes collectively establish the baseline for how animals must be cared for during transport.

The 28-Hour Law. For extended trips, federal hauling rules — like the 28-Hour Law — require commercial haulers to give livestock a break for feed, water, and rest every 28 hours. Short trips under 150 miles may avoid some requirements, but you should not assume exemption. The 28-Hour Law applies to livestock transported by rail or motor vehicle across state lines in interstate commerce. For purely intrastate Minnesota trips, the law does not directly apply, but it represents the accepted baseline for humane transport duration.

Hours of service and livestock exemptions. Motor carriers transporting livestock have been eligible to use the 150 air-mile exemption from the hours-of-service (HOS) rules at the end of a trip since November 15, 2021. The HOS rules are not in effect for livestock haulers between a point 150 air miles from the source of the livestock and a point 150 air miles from the place where the livestock will be delivered. This is a meaningful operational relief for most Minnesota livestock movements, which tend to be regional.

30-minute break waiver. In response to industry concerns over animal welfare, the 30-minute break requirement is waived when live animals or bees are on the vehicle. This means commercial drivers hauling live livestock are not required to take the standard 30-minute rest break that otherwise applies after 8 hours of driving, as long as animals remain on board.

Trailer floor condition. Inspect the trailer floor before each trip to make sure it is sturdy and clean. If more traction is needed, install rubber matting. Consider replacing floorboards that are showing signs of wear or rot. A compromised floor is both a safety hazard for your animals and a likely out-of-service violation at a roadside inspection. Officers check floor integrity as part of standard livestock trailer reviews.

Ventilation. While Minnesota statutes do not specify ventilation slot dimensions, adequate airflow is required to prevent heat stress and suffocation. Slatted sidewalls, roof vents, and adjustable air gaps are standard on commercial livestock trailers. In summer months, ensure vents are open and unobstructed before loading — heat buildup inside a sealed trailer during a Minnesota July can become life-threatening for animals within minutes.

Weight distribution and loading. When using a bumper pull trailer, place the heaviest animals in front of the axles. Load older and larger animals first, followed by younger and smaller animals. Proper weight distribution protects both your animals and your towing vehicle’s handling stability.

Key Insight: Minnesota’s Board of Animal Health has authority to hold livestock at the first in-state station with suitable facilities if transport rules have not been followed. The inspection is at the owner’s expense. Proper loading, documentation, and animal condition records protect you from this outcome.

If you raise livestock in a residential or semi-rural setting, you may also want to review rooster laws in Minnesota and kennel zoning laws in Minnesota for related local regulation guidance.

CDL and Driver License Requirements for Hauling Livestock in Minnesota

Whether you need a commercial driver’s license (CDL) to haul livestock in Minnesota depends on a specific sequence of weight thresholds, commercial intent, and vehicle configuration. Work through the following steps before your next trip.

Step 1 — Check your truck’s GVWR. Check your truck’s GVWR. Is it over 26,000 pounds? If yes, you need a CDL regardless of what you are towing. If no, move to Step 2.

Step 2 — Check the combined GVWR. Check your trailer’s GVWR. Does the combination of the truck’s and trailer’s GVWR exceed 26,000 pounds? If yes, continue to the next step. If no, you do not need a CDL.

Step 3 — Check the trailer’s GVWR alone. Check your trailer’s GVWR. Is it over 10,000 pounds? If yes, continue to the next step. If no, you do not need a CDL.

Step 4 — Living quarters exemption. Does your trailer have living quarters or temporary living quarters? If yes, continue to the next step. If no, you need a CDL. This is where gooseneck trailers with living quarters can qualify for an RV exemption.

Step 5 — Commercial intent. Are you in commerce or using your truck and trailer for business-related reasons? If yes, you need a CDL. If no, you do not need a CDL.

RV exemption for horse and livestock trailers. In Minnesota, recreational vehicles (RVs) are exempt from having a CDL. RVs contain temporary human living quarters and are used strictly for recreation. Gooseneck horse trailers with living quarters meet the definition of RV and may be exempt from a CDL. To be exempt, the truck must have a GVWR below 26,000 pounds and you must not be in commerce.

Commercial use changes everything. For example, if you are a trainer and training horses is your business and livelihood, and you are hauling horses to a show for clients with a truck and trailer combination exceeding 10,001 pounds, it is a commercial motor vehicle. However, if you take the same truck and trailer to take your personal horses trail riding as a personal vacation, it is not considered a commercial motor vehicle. As a vacation, nonbusiness-related trip, you are exempt for those days.

Situation	CDL Required?
Truck GVWR over 26,000 lbs	Yes
Combined truck + trailer GVWR over 26,000 lbs, trailer over 10,000 lbs, no living quarters, commercial use	Yes
Same rig, personal/recreational use only	No
Gooseneck with living quarters, truck GVWR under 26,000 lbs, personal use	No (RV exemption)
Combined GVWR under 26,000 lbs	No

Interstate vs. intrastate age requirements. If you operate only in Minnesota and the vehicle’s or combination’s GVW is greater than 10,000 pounds, commercial motor vehicle drivers must be at least 18 and possess a valid USDOT physical card. If the vehicle’s or combination’s GVW is greater than 10,000 pounds and you cross state lines, commercial motor vehicle drivers must be at least 21 and possess a valid USDOT physical card.

Federal exemptions for non-commercial haulers. You will not be required to follow federal hours-of-service regulations or hold a CDL if you are transporting horses or animals to shows, events, or for another personal reason. In other words, if the transportation is not part of a business, the FMCSA considers you exempt. However, just because the federal DOT does not require you to hold a CDL does not mean your state will allow you to operate without one. It is always a good idea to check with your state’s licensing agency to ensure you are operating compliantly.

Passing Roadside Inspections With a Livestock Trailer in Minnesota

Minnesota State Patrol troopers and MnDOT enforcement officers conduct roadside inspections of commercial vehicles on trunk highways, at weigh stations, and at designated inspection sites. If your livestock trailer qualifies as a commercial motor vehicle, you are subject to these inspections — and being unprepared can result in an out-of-service order that strands your animals on the road.

Weigh station stops. If your vehicle’s or combination’s GVWR exceeds 10,000 pounds, you must stop at the weigh station. All drivers are subject to weigh stations in Minnesota. Most weigh stations will take your vehicle’s weight as you enter, and lights will further direct you through the weigh station. There are six operating weigh stations in Minnesota. Know their locations on your planned route so you are not caught off guard.

What inspectors check. Minnesota roadside inspections follow the North American Standard Inspection (NASI) protocols used across the U.S. and Canada. Officers typically review:

• Driver’s license class and CDL endorsements (if applicable)
• USDOT number display and carrier identification
• Registration and operating authority documents
• Annual vehicle inspection report
• Brake function and adjustment
• Lighting — taillights, brake lights, clearance markers
• Trailer floor structural integrity
• Safety chains and coupling devices
• Tire condition and inflation
• Hours-of-service logs or ELD compliance (for applicable commercial operators)

Enforcement tools used. Minnesota law enforcement personnel use several different types of weighing equipment to monitor overweight loads. These include portable scales, weigh-in-motion scales, approved privately owned scales, and official truck weigh stations along state trunk highways and Interstates. Weigh-in-motion technology means your axle weights can be captured before you even see a trooper — do not rely on being waved through.

Out-of-service criteria. An out-of-service order stops your trip immediately. Common triggers for livestock trailers include brake defects, broken floor boards, non-functional lights, missing inspection documentation, and overweight axles. With animals on board, an out-of-service order creates an immediate animal welfare problem — you cannot legally move the vehicle until the violation is corrected.

Pro Tip: Conduct your own pre-trip inspection using the same checklist officers use. Walk around the trailer, check all lights, test the brakes, inspect the floor, verify the coupling and chains, and confirm your documents are in the cab. A five-minute pre-trip check can prevent a multi-hour roadside delay with a trailer full of animals.

Covered Farm Vehicle inspection exemptions. When the gross vehicle weight is 26,001 pounds or less and is operated anywhere in the United States, or when the GVW is greater than 26,001 pounds and is operated wholly within its state of registry or within 150 miles of the farm when crossing state lines, vehicles that transport agricultural commodities, livestock, machinery, or supplies to or from a farm may qualify for Covered Farm Vehicle status. CFV-designated vehicles receive certain regulatory exemptions, but they must still carry the self-designation form and comply with Minnesota vehicle safety requirements.

Interstate travel and destination-state rules. If you haul your livestock outside of Minnesota, you must follow the laws of the state you are traveling in. Just as you would follow speed limit changes from one state to another, you also need to abide by all other state motor vehicle laws. If you travel into another state, you are an “interstate” carrier. That status triggers additional federal compliance requirements and higher driver age minimums.

Animal health documentation at inspections. To prove ownership and track livestock from one owner to the next, most states require livestock like cattle, goats, sheep, or swine to have some form of ID — such as eartags, RFID tags, brands, or tattoos. Minnesota Board of Animal Health rules require Certificates of Veterinary Inspection (CVIs) for certain species movements. If Board of Animal Health rules have not been complied with, transportation companies shall notify the board and shall hold the animals or poultry at the first station within Minnesota where there are suitable facilities for inspection. The inspection must be at the owner’s expense.

Staying current on Minnesota animal health and ownership regulations can help you avoid compliance gaps across related areas.

Conclusion

Transporting livestock in Minnesota involves more moving parts than most haulers initially expect. Your registration status, trailer weight, driver license class, vehicle dimensions, animal welfare standards, and inspection readiness all interact — and a gap in any one area can derail a trip or result in penalties.

The key action items are straightforward: know your trailer’s gross weight and whether it triggers registration and CDL requirements, confirm your USDOT number is displayed if required, keep annual inspection documentation in the cab, verify your axle weights match the roads on your route, and conduct a thorough pre-trip inspection before every load. If you haul commercially or cross state lines, layer in federal FMCSA requirements on top of Minnesota’s state rules.

When in doubt, contact the Minnesota Department of Transportation’s Office of Freight and Commercial Vehicle Operations or the Minnesota Board of Animal Health directly. The regulations are detailed, but the underlying goal is simple: safe roads and healthy animals.
