PREFACE TO THE RULES:

All mentions of RTS/ PRI will hereafter mean The Rolling Thunder Show as members of Promotorport-Raceway- International. In consideration of acceptance by the RTS of the Drivers Licence application and payment of license fees, the signee agrees to abide by all rules and regulations of PRI, as to conduct and mechanical specifications, as now published in the Official PRI Rule  sheet, or hereafter modified. RTS/PRI reserves the right to alter or amend these rules and/or regulations at any time in the interests of safety, cost control and/or fair competition.

It is the responsibility of each competitor to read and fully understand the contents of these rules. If there is a disagreement or dispute regarding the meaning or application of these rules, the interpretation and application of the officials at the track shall prevail. Appeals may be considered by RTS /PRI.

Any rules updates or safety bulletins published by  PRI  for the purpose of implementing, interpreting or enforcing these rules will be deemed as part of and will supersede these rules. The rule updates or safety bulletins will only appear on official RTS/PRI letterheads, or in the official publication of an PRI face book  pages.  The rule updates will also be posted on the Rolling Thunder Show and Promotasport Raceway International  websites.

The rules and regulations set forth herein are designed to provide orderly conduct for PRI events and to establish minimum acceptable standards and requirements for such events. These rules and regulations shall govern the conditions of all PRI promoted events, unless otherwise noted. All members are required to comply with these rules.  No express or implied warranty of safety shall result from publication of, or compliance with these rules and regulations. They are intended as a guide for the conduct of the sport and are in no way a guarantee against injury to participants, spectators, or others. No pretense is made for having designed a foolproof set of rules and regulations. The spirit and intent of these rules is the standard by which PRI promoted racing is guided. Race Scrutineers are authorised to decide if an equipment change is an attempt to circumvent these rules.  Officials can and will disqualify an entry in violation of the spirit and intent of these rules. Since it is impossible to anticipate every potential circumstance, a PRI scrutineer or official shall have the right to initiate action correcting a hazardous condition or a condition not in compliance with the spirit and intent of these regulations.  Decisions are to be based on “common sense”, consistency, impartiality and fair play. Developments in racing may necessitate changes that we cannot anticipate at the time the rules were written.

If this rulebook does not specifically say that you can change, modify, add something, then you must consider that the change, modification, addition is illegal. Any questions about the legality of a change not covered in this rule book, must be answered by PRI officials and that decision is final.

RTS MEMBERSHIPS
