Livestock Transport Fatigue

Long hauls tire animals and drivers. Planning rest, water, route and timing reduces stress on animals and lowers the risk of a crash.

What is transport fatigue?

Transport fatigue refers to the tiredness and stress animals experience from standing in a moving vehicle, balancing, dealing with noise and unfamiliar surroundings and going without feed or water. Longer trips and rough roads add to it.

It also describes tired drivers. Early starts, long days and late arrivals make drivers less alert, and a tired driver with a loaded stock trailer is a risk to everyone on the road.

Stress adds up. Animals that have been handled, mixed, fasted and driven over a long distance may be more prone to illness, which is why planning matters before they ever step on the trailer.

How does it show in animals?

Signs can include weakness, reluctance to stand, stumbling, heavy breathing, loss of body condition and more illness after the trip. Some animals show few signs at first but are more prone to disease after a stressful journey.

Veterinarians and extension livestock specialists can explain what to watch for in each species. Seek their advice instead of relying on general rules from memory.

• Stumbling or reluctance to stand
• Heavy breathing or restlessness
• Weakness after unloading
• Poor appetite or illness days later

Are there rules on transport time?

Some rules limit how long certain animals may be confined in a vehicle without feed, water and rest, and they differ by species, by state and by whether the animals cross state lines. We do not give any time limits here.

Check with the U.S. Department of Agriculture, your state department of agriculture or state veterinarian, and your extension office to learn which rules apply to your situation.

A veterinarian can also help you understand when certificates or inspections are needed for movement between states, and the state veterinarian's office can answer questions about animal movement rules.

How do you plan a long haul?

Plan the route, rest stops and destination before loading. Consider whether the trip could be split, whether a closer facility is available or whether it can wait for better weather. Make sure the destination is ready to receive the animals promptly.

Share driving where possible and plan breaks for the driver. Check animals at safe stops, and avoid unloading in unfamiliar places unless it is part of a planned rest.

Think about the driver's shift as well as the animals' time on board. A well-planned relay of drivers is often safer than one person pushing through, if the animals are comfortable and the route is safe.

• Plan the route and rest stops
• Check whether a closer facility is possible
• Confirm the destination is ready
• Share driving when you can
• Check animals at safe stops

How do you reduce stress for animals?

Handle animals calmly and prepare them gradually. Avoid mixing unfamiliar animals if you can, load at a comfortable density and drive smoothly. Avoid sudden braking, sharp turns and rough shoulders.

Keep the trailer clean, dry and well ventilated. Ask your veterinarian about feed and water before a trip, and about care afterward.

• Handle animals calmly
• Drive smoothly and brake early
• Avoid mixing unfamiliar animals
• Keep the trailer clean and ventilated

How do you protect the driver?

Get proper rest before a trip, avoid long stretches without breaks and stop if you feel drowsy. Do not rely on caffeine, loud music or open windows to fix tiredness. Fatigue is a safety hazard for everyone on the road.

NIOSH publishes information on work schedules and fatigue, and many state agencies offer driver safety material. If you cannot stay alert, stop in a safe place and rest or hand over the wheel.

Talk to family about expectations. A person who feels pressure to arrive on time may take risks, so agree in advance that stopping to rest is acceptable.

• Rest before the trip
• Stop if you feel drowsy
• Do not rely on caffeine alone
• Hand over the wheel if possible

What should you do on arrival?

Unload calmly and promptly, offer water as advised and observe animals closely over the next days. Watch for signs of illness and call your veterinarian if you notice any.

Review the trip with your crew and note what could be improved, from route to timing to rest stops.

• Unload calmly
• Offer water as advised
• Watch for illness over the next days
• Call your veterinarian if concerned
