The purpose of this legislation, known as the Horse Transportation Safety Act of 2025, is to enhance the safety and welfare of horses during transportation. It specifically aims to prohibit the transportation of horses in multi-level motor vehicles, which can pose risks to their health and safety. The key provision of this law is the outright ban on transporting horses in vehicles that have two or more levels stacked on top of each other. This applies to any motor vehicle used for interstate transportation, meaning moving horses between states or territories within the U.S.
