Hauling to the Race: A Trailer Safety Checklist for Barrel Racers
The AP Barrel Co. Team · November 8, 2026
Ask any barrel racer how they spent their weekend and the honest answer is usually "driving." A 15-second run can come at the end of hours on the highway, and the trip is where a lot can go wrong. The good news is that most trailer trouble can be caught in the driveway, before the horse ever steps on.
This checklist pulls together guidance from university extension programs at the University of Maryland, the University of Georgia and the national eXtension horse program. Print it, keep it in the truck, and run through it before every haul.
Before You Hook Up: The Trailer
Start inside the trailer. The University of Georgia's equine program suggests looking for loose or sticking-out nails, bolts and screws, clearing the drainage holes, checking for wasp and bee nests, and making sure every lock and divider works. Swap out old hay for fresh.
Then check the floor, because a horse stands on it the whole trip. Pull up the mats and look for soft spots, rot, cracks or corrosion, on the floor and on the ramp if you have one. After a trip, UGA recommends lifting the mats, sweeping or hosing the floor and letting it dry before the mats go back, and replacing rotten boards once a year.
Tires deserve more attention than most of us give them. Look for bulges, cracks from dry rot, slices and worn tread on every tire, including the spare. UGA recommends at least a quarter inch of tread and suggests confirming your state's rule with the DMV. Check the air pressure on all of them, and make sure the lug nuts are tight.
Lights should all work and be bright: marker, tail, brake, turn signals and the interior light.
Hitching Up
The University of Maryland's fact sheet starts with the truck itself: make sure its tow rating is enough for your trailer with horses in it. A longer wheelbase is more stable, and a bigger, heavier trailer needs more power.
When you hook up, confirm the ball matches the coupler, grease the ball, and check the safety chains, the electrical plug and the breakaway system. Once hitched, the trailer should sit level, not nose-up or nose-down. Whenever the trailer is unhitched, chock the wheels.
Brakes matter most when your horse is standing behind you. Make sure the breakaway battery is charged. Before getting on a busy road, Maryland recommends driving a short distance and testing the brakes, and adjusting the brake controller if the trailer pushes the truck when you slow down.
Once a Year
Some jobs only come around once a year, and a slow month in the race season is a good time to get them done. UGA's yearly list includes checking the frame for cracks, checking the wiring for loose connections and worn coverings, greasing hinges and springs, checking ramp hinges, and pulling the wheels to check and repack the bearings. Have the brakes, breakaway cable and controller inspected too. If you are not comfortable doing this yourself, a trailer shop can do it.
What to Keep in the Truck
Maryland's fact sheet suggests three kits.
A safety kit: a fire extinguisher, a flashlight, reflective triangles, tire-changing equipment rated for your rig's weight, and a pocketknife so you can cut a tie rope in an emergency. UGA points out that ignitable flares should not be stored in the horse trailer because of the fire risk.
A horse first aid kit: non-stick bandages and gauze, self-sticking bandage, bandage scissors, a thermometer, eye wash, antiseptic ointment and electrolytes. Ask your veterinarian what else belongs in your kit, including any medication and how to use it.
Emergency information, kept in both the truck and the trailer: your cell number, your horse's name and registration, your vet's phone number, your home or barn address, and vaccination records. If something happens on the road, a stranger or first responder may need it.
Papers
Health papers are easy to forget until you are standing at the race office. The eXtension horse program notes that for out-of-state travel a horse generally needs a negative Coggins test drawn within six months of travel and a health certificate signed by a veterinarian within 30 days. Rules vary by state, and race producers and venues can set their own requirements, sometimes stricter than the state's. Check with your vet before you cross a state line, and check the race flyer or call the office before you haul.
Loading and Tying
Load early, and keep it calm. UGA notes that a calm loading lowers the stress of the trip. Haul in a halter that fits well and will break in an emergency. Leather breaks more easily than nylon. Never wrap the lead rope around your hand.
Tie with a quick-release knot or a quick-release trailer tie, and give your horse enough rope to balance with its head and neck, but not enough to get a leg over or get tangled. Know how you would get out of the trailer in a hurry, and keep that path clear.
Air, Water and Hay
Fresh air matters year round. In warm weather open every vent and window. In winter, don't close the trailer up tight, because horses need air moving through all the time. Keep window bars and screens closed on the road, and never let a horse ride with its head out of the window.
The eXtension program recommends stopping every three to four hours, for 30 to 60 minutes, offering water at each stop and more often when it is hot. You don't have to unload at every stop. Park in the shade when you can. Hydration helps prevent problems like colic, and some horses won't drink strange water, so bring water from home or ask your vet how to get a picky drinker to drink.
Keep a full hay net in front of your horse, and carry extra nets on long trips so you can swap them quickly. Straw or shavings on the floor give cushion and soak up urine.
For trips longer than about 18 hours, both eXtension and Maryland recommend a longer rest with the horse unloaded and stabled overnight.
On the Road
Driving with a horse behind you is different driving. Start, stop, change lanes and turn smoothly. UGA suggests a four-second following distance, driving for the road conditions rather than the speed limit, and putting the phone away. Practice driving and backing with an empty trailer before you haul a horse, and set your mirrors before you leave.
Every time you stop, walk around the rig: tires, lights, hitch. It takes a minute and it catches problems while they are small.
When You Get There
Horses can be wound up after a haul in a new place, so keep a good hold when you unload. Let them stretch their legs, offer water and give them time to settle before you warm up.
Plan the Weekend Before You Leave
Knowing how far you are going and how long it will take is part of hauling safely. The Events page on The AP Barrel Co. lets you search barrel races by town, state or ZIP, and members can save races to their own calendar and plan a whole race weekend. When a race takes entries on AP AlleyPass, you can enter online, book your stall or RV spot and get a check-in pass on your phone before you hook up.
Safe travels, and good luck on your run.
