Relates to harness racing

This bill amends racing law to define "racing" as exclusively involving registered standardbred horses harnessed to a sulky or similar vehicle. It directly affects harness racing tracks by requiring all races to use only these registered horses, excluding any racing where horses are mounted by jockeys. The key provision changes the legal definition in the racing statute to restrict competition to standardbred harness racing, eliminating other formats like flat racing at these venues. The law takes effect immediately upon enactment.
