Never climb under or over dividers, chest bars or the horse to exit the trailer. Never leave yourself in the position of being trapped in the trailer with the horse between you and the exit. Make sure that the trailer is securely and properly hitched to the towing vehicle before loading a horse. Never load a horse or leave a horse in an unhitched trailer. Do not unhitch a trailer with a horse still inside.
Trailers are very unstable and can easily tip on end.
When loading a single horse, place the horse on the left side of the trailer. When trailering two horses, place the heavier horse on the left side. This will make towing the trailer smoother and the ride easier for the horse because of the crown contour of the road surface. When approaching the ramp make sure the horse is in the center of the ramp so that the horse does not step off the sides. If the horse pulls back before the butt bar is in place it wont break the tie, the halter or fall down.
