Why stop every 3.5 hours?

Research from UC Davis shows that horses transported for more than 4 hours without a break have significantly higher respiratory bacterial counts. Stopping every 3–3.5 hours to lower heads and clear airways reduces shipping fever risk.

Should I unload horses at rest stops?

Generally no. Unloading and reloading at highway rest stops is risky (unfamiliar terrain, traffic, no fencing). Keep horses on the trailer with windows open. Only unload for overnight stops at a safe facility.

How long can a horse safely travel in one day?

Most healthy adult horses can handle 8–12 hours of travel in a single day with adequate rest stops. Beyond 12 hours, plan an overnight stop. Young, old, or compromised horses should travel shorter distances.

Should I feed during the trip?

Yes — hang a hay net in the trailer. Hay keeps the digestive system active and reduces stress. Avoid grain during transport. Offer small amounts of water at each rest stop.

Rest Stop Schedule

Enter trip duration and departure time to generate the rest stop schedule.

Based on UC Davis Center for Equine Health transport guidelines and AAEP recommendations. Stop every 3\u20133.5 hours for 20 minutes to reduce shipping fever risk. Always carry a current health certificate and Coggins test for interstate travel.

How It Works

Enter trip duration, departure time, and optionally customize the stop interval and duration. Default settings are a stop every 3.5 hours of driving with each stop lasting 20 minutes. The planner generates a schedule showing every rest stop with exact start and end times, then calculates your adjusted arrival time including all rest breaks. During each stop, open trailer windows/vents for fresh air, offer water in small amounts, allow horses to lower their heads to clear respiratory secretions, do a visual check of legs, bandages, hay, and water, and do not unload unless stopping overnight. Export to ICS calendar for phone reminders or CSV for your trip binder.

Transport Safety

Before the trip: obtain a health certificate (required for interstate travel), Coggins test (within 12 months, some states 6 months), inspect trailer (tires, lights, floor, hitch, breakaway brake), load hay nets, water buckets, and emergency kit, and bandage legs with shipping boots or standing wraps. During transport: drive smoothly avoiding hard braking and sharp turns, monitor ambient temperature, stop on level ground when possible, and never park in direct sun with horses loaded. After arrival: unload carefully as horses may be stiff, offer small amounts of water frequently for the first 2 hours, monitor temperature, appetite, and manure for 48 hours for shipping fever risk, and take rectal temperature twice daily for 3 days post-arrival. Shipping fever is pleuropneumonia from prolonged head elevation during transport, with signs appearing 24–72 hours after arrival including fever over 102°F, nasal discharge, and depression — this is a veterinary emergency.

Method

Default rest interval: every 3.5 hours of driving. Default stop duration: 20 minutes. Both are adjustable. Stops allow horses to lower their heads (clearing airways), rehydrate, and stretch. Total trip time is adjusted for cumulative rest. Based on UC Davis Center for Equine Health transport guidelines and AAEP long-haul recommendations.

Equine Transport Physiology

During transport, horses must constantly brace against vehicle movement, which is physically demanding — heart rates are elevated 15–25% above resting. The head-up posture required by most trailer designs impairs mucociliary clearance, allowing bacteria to accumulate in the lower airways. This is the primary mechanism of shipping fever (pleuropneumonia). Dehydration accelerates because horses often refuse water during transport, while respiratory water loss increases. Cortisol levels rise within the first hour and remain elevated, suppressing immune function. These physiological stressors compound over time, which is why regular rest stops are essential for trips over 3–4 hours.
