The word demolition means collisions and hitting two objects together while derby mean a race. These two words put together creates a competitive place for people to enjoy derby cars. Demolition derby drivers come from long family history of drivers. The pasion starts when they are old enough to walk, helping dad at the garage. He can remember their first demolition derby going forty miles per hour, smashing into another car and coming in third. From that moment on, he was hooked. From my experience and research, I know there is a lot of time and effort that goes into building the car, participating in the demo derby, and keeping a driver and spectators safe and these are the three areas of focus on in this paper.
The first area that is important to understand when entering demo derby is the general rules. Rules for the participants have to be followed in order to participate in the demo. These rules help to keep the playing field even. These rules can change depending on the promoter that is in charge. The promoter has the full authority to allow participants to race or to tell them that their vehicle is too over built. The participant then must put it back on the trailer and cannot participate in the derby. An example of these rules entering the right vehicle into the right class. A typical night at the derby would have five different derby classes a night. The class are determined by wheel base. A truck cannot be entered in a derby classification against a van because a truck has better motor, stronger body frame and would completely destroy the van. In an impact like this, the driver of the van could possibly be hurt.
At any derby event, some participants will have participated in many many times; some will have come for the first time. The promoter is tougher on the new participants and will look their cars over a lot. The promoter will not spend as much time checking a car if the participant is a seasoned driver. The car may be checked quickly to see if any new modifications have been made.
Steve Heitman is a local Impact Motor-Sports Promotion (IMP) manager. He has a list of rules for each participant in each class. He places arranges a number of events throughout the derby season.
The rules the IMP has depends on the class a participant is in. Every vehicle has to follow the set of general rules in order to compete in the derby. The main reason for these rules are to keep the cars and participants safe. An example of a class rule is the Mega Stock Mid-Size Car rule. This rules states that no functioning all-wheel or four-wheel drive vehicles are allowed. (Heitman 1) The mid-sized vehicle must operate with front-wheel or rear-wheel drive only. All-wheel drive mechanism must be disengaged.
Generally, the derby vehicle must be left completely as factory stock. A participant cannot swap out a motor. The vehicle is run with the motor that was originally put into that car. The computer must remain with...
