Check how many horses a trailer can safely carry by weight.
A safety margin reduces the trailer's usable load, and the horse weight then divides into that reserved capacity. Overloaded trailers destabilize towing and strain axles, so counting horses against a margin keeps every trip legal and safe.
Horse Trailer Capacity
Usable load = max load x (100 - margin%) / 100; horses = usable / horse weight
