58 Pa. Code § 183.282
Complaints by drivers of foul driving or other misconduct during the heat or dash shall be made at the termination of the heat or dash, unless the driver is prevented from doing so by accident or injury. At the conclusion of each heat or dash, every driver shall return to a point designated by the presiding judge to be dismissed by the judges. A driver desiring to enter a claim of foul or another complaint of violation of the rules shall indicate to a judge his desire to enter a claim or complaint and forthwith upon dismounting shall proceed to the telephone or judges stand where and when the complaint shall be immediately considered. In cases of injury to either horse or driver or broken equipment, the driver may approach the nearest official on foot and indicate his desire to enter a claim of foul. Otherwise he shall make the claim before dismounting. The judges may not cause the official sign to be displayed until the complaint has been entered and considered. After being dismissed by the judge, drivers shall return to the paddock and remain there until the race is made official.
