Marshals are stationed at various places around the track and have to be quick so as not to get hit by an oncoming car. Two marshals rush to help and overturned car during a race. They want to be quick to avoid being hit by another oncoming car. When the race ends, the racers remove their cars from the track and station themselves on the field to serve as marshals for the next race. Once racers have fulfilled their marshalling duties, they usually return to the sanctuary of their repair tables, stationed around the parking lot.
Repairs are usually necessary.
It is common for racers to return to their pits with broken parts and broken egos.
