The following Race Car Rules are locked in for 3 years (2010 - 2012 race seasons).

The rules set forth herein are designed to provide fair parameters for competition and a high level of safety. No expressed or implied warranty of safety shall result from publications of or compliance with these rules and regulations, they are intended as a guide for the conduct of sport and are in no way a guarantee against injury or death to participant, spectator, or official. Driver/Car owner is legally responsible for all crew signed in under car.

It is the Driver/Car Owner’s sole responsibility to ensure his or her car is legal. If there are questions regarding the rules, please seek clarification from any member of the rules committee prior to arrival at the track. Non-conforming cars will generally be permitted to run, except for the Tech Officials discretion regarding safety related items.Tech Officials will work cooperatively with any driver/car owner to develop a reasonable timeline for bringing any existing car into compliance with the revised rules.  Penalties of additional weight and/or weight percentage changes may be implemented during this interim period for non-conforming cars.

All of the rules are to be read and interpreted in the “spirit of the rules”. The intent of these rules will not change for the 3 race seasons specified. Any issue of alternate interpretation (grey area) will result in the specific rule wording being adjusted if required to reflect the original intent. These adjustments may be made at any time during the term of the rules.

Interpretation of these rules and regulations is left to the sole discretion of the Okanagan Street Stock Club’s appointed Tech Officials.  All race cars are subject to inspection by Tech Officials prior to being allowed on the track, at any time during the race program, and/or after the main event.  Tech Officials have the authority to refuse any car the right to practice or race.

 The Driver/Car Owner must clearly declare any components of the car to Tech Officials if requested, and remove any parts required for inspection.  Failure to cooperate with Tech Officials will result in the race car being deemed illegal and may result in disqualification, fines and/or suspension.

 Decisions by the Tech Officials may be formally appealed to the Rules Committee.  The existing Rules Committee will remain in place for the duration of the rules (3 years) to provide the Tech Officials with any interpretation of the rules that may be required, make rulings on appeals, and to make any necessary wording changes to the official rules.
