PROCEDURAL RULES:


28. NON-CONFORMING CARS – To encourage participation, vintage style cars from other clubs will be allowed to participate one time per season without becoming a member. Non-conforming cars must meet the minimum safety standards of the club and meet track safety rules. After the race the Technical Committee will rule on any infractions or changes that need to be made on the non-conforming car before it could be considered for regular registration with the club. Non-conforming cars are not eligible to win events or collect trophies.

29. TECHNICAL COMMITTEE –The Technical Committee will be charged with enforcement of the rules and will make rulings on subjects not covered or set forth in these rules. (technical committee rulings are final).

A group of three (or more) club members, plus the club coordinator, assembled to decide on a questionable rule, car, component or procedure shall constitute a "technical committee". A technical committee may be convened at any time, by the club coordinator. Race day decisions made by the club coordinator with consultation with at least three members of the club shall be valid as a "technical committee ruling". All technical committee rulings are subject to further discussion by club members prior to being incorporated in the club’s official rules.

30. LINE-UPS for Racing Events - Feature lineup will be posted at designated location (usually at one of the vehicles in Pit Area). It Is the driver’s responsibility to know where they start in each event (if you are moving to the back of the field or if you are scratched from the race, you must let the person doing lineup know before feature is posted). Starting lineup for the race will be achieved by drawing for position before each race (except previous winners). Anyone who wins will start in the rear of their next race. Any car or driver winning three (3) events in a single season will be required to start at the rear of the field for the balance of the season. The Technical Committee may change the lineups at their discretion, to level the playing field for all competitors. Cars unable to start under their own power must start at the rear of the field.
[After any member’s second win, in one season, the Technical Committee may rule on adding more weight, limiting gear ratios or otherwise reducing speeds of exceptionally fast cars. The club goals are good competition, not domination]

31. ON-TRACK PROCEDURE for Racing Events – For club race events, the event will be conducted as an actual race and all of the hosting track’s rules regarding starting, restarting, flagging, etc…will be in effect. Complete control and discretion shall be in the hands of the hosting track’s officials. Please keep in mind that these are vintage cars and every attempt should be made by the drivers to avoid incidents. Rough or overly aggressive driving will not be tolerated and the technical committee may rule on incidents even if the hosting tracks’ officials have ignored them. ALL DRIVERS SHALL CONDUCT THEMSELVES PROFESSIONALLY AND USE COURTESY TOWARDS THEIR FELLOW PARTICIPANTS AND ALL TRACK OFFICIALS.

32. SPORTSMAN DIVISION CARS – Until such a time that car counts dictate separation, Sportsman and Modifieds will race together with line-ups drawn regardless of division. Upon conclusion of the race event, the highest finishing car registered as a Sportsman will be recognized as the Sportsman class winner. In the event that a Sportsman car is able to finish ahead of all the Modified division cars, the Sportsman car will be declared the overall race winner and no winner’s award shall be made to the highest finishing Modified division car, nor shall the next highest finishing Sportsman be recognized as the class winner.

33. OVER COMPETITIVE CARS – All club members and participants should keep in mind that many of today’s modern classes of racecars are quite expensive and have gotten out of reach, financially, to the average person. One of the primary goals of the club should be to keep the costs of being competitive at a reasonable level to ensure healthy car counts. Technical infractions discovered at the conclusion of a race may result in disqualification or other penalty. Repeat offenders may be punished by suspension and/or expulsion from the club.

34. RULES SUBJECT TO VARIATION – All club rules are subject to variations at the discretion of the club coordinator. In most instances, variations will be used to bolster car-counts and encourage participation. Technical Committee may be convened if dispute arises.

35. RULES MEETING – A meeting will be held annually where current and proposed rules can be discussed and a vote of members in attendance can be taken on any changes considered. It is recommended that rule change proposals be submitted in writing at least two weeks prior to any scheduled rules meetings.
