Horse Transportation Safety Act of 2025

This bill would make it illegal to haul horses across state lines in motor vehicles with two or more levels stacked on top of each other. It defines “motor vehicle” as something made for use on public highways, not rail, so the rule targets multi-level highway trailers often used to move livestock. It also adds fines for breaking the rule: $100 to $500 for each horse transported in a stacked trailer, on top of any other penalties under other laws.

Key points

• Who’s affected: Horse owners, shippers, transport companies, and event organizers who move horses between states.
• What changes: No more interstate transport of horses in double-deck (or multi-level) highway trailers; each horse moved that way can trigger a separate fine .
• Penalties: Civil fines of $100–$500 per horse, plus any other penalties allowed by law.

If passed, this would push haulers to use single-level trailers that give horses more headroom and reduce injury risk during long trips.
