These rules are developed with the cost of car construction in mind. The cars are to be constructed according
to the rules. If certain items are not specified, it doesn’t mean it is legal. The judges decision will be final, so call
before you do something that you don’t understand. The sport of demolition derbies has grown from a backyard
fun activity, to a hardcore profession for some people. It is our intent at T.E. Promotions to keep the playing field
fair so that local people can still compete and have fun.

| IMPORTANT: PREPARATION OF CAR |
Cars are to be constructed according to rules. We have always mandated a fair playing field and this year specific
measurements have been adopted to several areas of the rules. Demo derbies have went from once a year event to
high dollar every weekend events. Many fairs that don’t have fair rules have seen car count numbers severely drop
off. Derby cars just like race cars must be built to the rules.
