PRE-TECH INSPECTION and RULES
This is a recommended visual inspection that should be done by owner/driver's prior to any racing at any track or function. These checks will make sure the above items meet a minimum safety guideline at the time the inspection was performed. It is recommended that this inspection be performed prior to each racing event and/or after any significant repairs are performed to the vehicle. This does not insure the safe operation of the inspected vehicle. Racing is a hazardous sport, which causes stress on all working pieces. It is the owner/driver's responsibility to maintain and keep their vehicle in safe working order.
