Driving Past Scales

[Richard Grant]

I notice where some racers have been re-instated because the winner drove past the scales. My question is: if the losing driver also drove past the scales are they(the loser) re-instated? I know in the past some racers have waited until the opponent passes weight and fuel before returning to the pits. So I wonder if the loser should follow that procedure or if they are re-instated anyway.
