N.J. Admin. Code § 13:71-20.7
All complaints by drivers of any foul driving or other misconduct during the race or heat shall be made at the termination of the race or heat unless the driver is prevented from doing so by an accident or injury. At the conclusion of each race or heat, any driver desiring to enter a claim of foul or other complaint of violation of the rules must, before dismounting, indicate to the patrol judge his desire to enter such claim or complaint immediately after the race and, upon dismounting, shall proceed to the nearest telephone and advise the judges of the complaint or foul involved. The judges shall not cause the official sign to be displayed until such complaint shall have been entered and considered. All drivers must return to the paddock and remain there until the race is made official. The judges will not consider any claim of foul instituted after the race has been made official.
