In New York, for example, a paddock code of conduct has been established:
4104.10. Code of conduct.
(a) While in the paddock:
(1) An owner shall not engage in conversation with a driver or trainer who is not employed by him for the owner's horse programmed to race the same day. A driver or trainer shall refuse to engage in conversation with any owner whom he is not representing in a race the same day.
(2) A driver or trainer shall not mark a program for anyone including his own owner.
(3) Owners, drivers and trainers shall so conduct themselves as to avoid creating any appearance or suggestion that would reflect adversely on the integrity of the racing.
The steward and paddock judge are authorized on any occasion to revoke or curtail the paddock privileges of an owner if, in the judgment of the steward or paddock judge, circumstances warrant such action in order to maintain proper decorum in the paddock.
