This Rule Book is divided into two Chapters. Chapter One is a compilation of the Rules and Regulations of The United States Trotting Association; Chapter Two consists of the Articles of Incorporation and Bylaws of the Association. Since it is anticipated that in most instances the user of this Rule Book will be concerned primarily with the chapter on Rules, it is important for such a user to understand that the rules recited herein relating to the racing of horses, as opposed to the registration of horses, are applicable only to those non-pari-mutuel meetings over which no State Racing Commission, or other State Regulatory Body asserts primary jurisdiction.

The rules governing the racing of horses at all non-pari-mutuel meetings and serve as a guide for states with pari-mutuel racing for the State Regulatory Bodies which promulgate and enforce their own rules.

Requirements: Compatible with iPhone, iPod touch, iPad, and Android. Requires iOS 5.0 or later or ANDROID: 2.1 and up.
