Nebraska Unified Rules - Demolition Derby
2010 and 2011 Car Building Rules
These rules will be used for the 2010 and 2011 seasons, and supersede all other previous years Nebraska Unified Rules.
You must first pass all Required Nebraska Unified Rules for Safety
Note: These are car building and preparation rules only. Any additional restrictions and rules such as no profanity, size of numbers on doors, registration times, age of participants, releases, local track rules, (such as no Imperials allowed, or 81’ and newer only cars) alcohol consumption, etc., are the duty of the promoter, and should be included on a separate sheet of paper.
These rules are for the full size, passenger cars only class. Imperials, front wheel drive, and mid-size cars are allowed. No compact cars, hearses, ambulances, limos, 4 wheel drive (other than AMC Eagle type cars but must have front drive shafts removed), vans, minivans, or any vehicle considered a "truck" or "SUV" allowed. “Cross-Over” type vehicles are up to the promoter and or officials for that specific event. Specific rules for the 1997 to 2002 and the 2003 and newer Ford cars are to be left up to the promoter and or officials for that particular demolition derby. When building these newer Ford cars, the rules for safety, and these build rules, must be followed. Please call first on specific rules for the front and rear suspension of these Ford cars.
If it is not allowed in the following rules, then do not do it.
Frame and Body Rules:
1. Official's decision is final.
2. No Imperial sub-frames under non-Imperial cars. 67’ – 73’ Imperial sub-frames under 67’ – 73 Imperials only. 66’ and older Imperial frames under 66’ and older Imperials only.
