SAFETY INFRACTIONS: If at any time during qualifying or eliminationís,
an entry exceeds the MPH or ET for which the car or driver are safely certified,
 or if the driver or car are found to be in violation of any other safety standards,
 the T.D.R.A.has the sole authority to: (1) restrict the driver and vehicle from
further runs until the problem is remedied or (2) disqualify the entry from the
 event. There is no recourse through the T.D.R.A. for any safety infraction
rulings made by the host track safety inspectors. If a vehicle during eliminationís
exceeds the MPH or ET that it is teched for, that vehicle will be immediately
 disqualified from further competition and the opponent he/she was racing will
advance in the eliminationís. If a car exceeds its MPH/ET rating during
qualifying it will receive one warning from the T.D.R.A. prior to disqualification.

ELIGIBILITY-CAR: An individual vehicle cannot be used for multiple
entry and hold multiple qualified positions in either a single eliminator or 
in multiple points earning eliminators.
ELIGIBILITY-DRIVER: The T.D.R.A. with the approval of the Tech
Director, has the option of allowing a vehicle change, but only under certain conditions:
*All previous event times are voided for vehicles and drivers involved.
*Changes must be made, and the driver re-qualify, during the normal
scheduled qualifying rounds for the event. No changes are permitted once 
eliminations have begun.
*Driver must stay within class and category entered.

These are a few of the rules that you will be required to meet in order to
compete at a T.D.R.A. event. We recommend that you obtain a copy of the
N.H.R.A. rulebook and read it over. Please pay attention to your class only!
We operate under the ET BRACKET rules, (pages 22-28). You only need
to read Section 1A and the general regs. The other pages are for classes we do not run.
