When getting in line, if the car ahead of you is not there yet, please leave room for them to pull in line.

In the event that a qualified car cannot make first round of eliminations, then a "break rule" will apply and the next car will be inserted. If no alternate is available, then the run will be considered a "break single" not a "bye run."
