ENFORCEMENT POLICY 2008
Flagrant violation of these rules set forth in this rule book will result in a two race suspension and loss of points. A second offense will result in an expulsion from the River Valley Lawn Racers Organization at the discretion of the committee members. All River Valley Lawn Racers are expected to conduct themselves in such a manner as to not cause detriment to either the River Valley Lawn Racers Organization or the sport of lawnmower racing when at a race or conducting related organization business. All decisions made by the governing body. (Majority of voting membership present at meetings.) The following rules and regulations are designed to provide for the orderly conduct of racing events and to establish acceptable requirements for such events. These rules shall govern the condition of all events. No expressed or implied warranty of safety shall result from publication of, or compliance with these rules and/or regulations. They are intended as a guide for the conduct of the sport and are in no way a guarantee against injury or death to participants, spectators, or others. As with any set of rules or regulations, the track officials reserve the right to add, amend, suspend, or adjust any rule or procedure which they deem necessary to aid in the production of racing. This will be done primarily for the purpose of maintaining safety and fair competition for all. The omission of any rule or guideline does not authorize any participant to assume legality. It is better to get clarification of a rule rather than be disqualified by assuming.
