2009 CDCRA Rulebook
The following are "common sense" type rules. Our objective is to minimize the need for rules changes. Do not attempt to build a Dwarf Car without first contacting a CDCRA board member for rules clarifications. If a car is built that does not meet CDCRA specifications it WILL NOT compete in CDCRA events. The Board of Directors reserves the right to make rulings based on the intent to preserve the concept of Dwarf Car racing and in the interest of fair competition. The following rules are for CDCRA Dwarf Cars. The rules, regulations and specifications set forth herein are designed to provide for the orderly conduct of racing events and to establish minimum acceptable requirements for said events. These rules shall govern the condition of all events, and by participating in these events, all licensees will be deemed to have complied with these rules. No express or implied warranty of safety shall result from the publication of or compliance with rules, regulations and/or specifications. They are intended as a guide for the conduct of the sport and are in no way a guarantee against injury or death.

If a car is involved in a second Yellow flag incident it will be Black Flagged and leave the track. If the starter deems a car unsafe for any reason, it will be Black Flagged, and must leave the track. Black Flag penalties for these cases will be scored as a DNF.

In the case of race results, the word “IN PROTEST” will be placed on the scoreboard, and no monies or trophies will be awarded until the Board resolves the matter. In the case of technical violations the technical Stewarts, and the Board will use the club approved measurement instruments to determine the validity of a protest.
