  RACE DAY POLICY'S
SCALES:
After each qualifying and elimination pass, all cars must stop and weigh at the track scales. If you lose in eliminations, and your opponent fails to make weight you will be reinstated into the eliminations only if you made minimum weight requirements. If both cars failed to make minimum weight, both cars will be disqualified. It is the driver's responsibility to verify with each track scale, the weight of his/her car prior to each race day. There will 5lb error factor allowed. 

TOW BACK:
All vehicles must drive or be pushed by the driver  to the track scales. Even on bye runs, car must still drive down to scales and weigh in. If vehicle is broken, you must first get permission from a PSCA official, before allowing tow vehicle past the scales (this is to insure no weight is added to vehicle) It is up to the PSCA officials whether a vehicle is allowed to tow to scales for mechanical problems.

BYE-RUNS:
All vehicles must take the tree, and run down the 1/4 mile.
