Article B5.16.2
End-of-session signal timing
Chapter: B5
In Simple Terms
If the race ends early (before all scheduled laps are completed), the official result is based on when the leader crossed the finish line just before the end signal was given. If the end signal is delayed, the race is still considered finished at its originally scheduled time.
- Early end signal: Results are determined by the leader's last crossing before the signal, not at the signal itself
- Delayed end signal: The race is deemed finished at its originally scheduled time, regardless of when the signal actually occurred
- Protects fairness by preventing the timing of the signal from artificially affecting final classifications
- Applies to all timed track championship sessions (practice, qualifying, race)
Official FIA Text
Should the end-of-session signal be given before the leading Car completes the scheduled number of laps, the TTCS will be deemed to have finished when the leading Car last crossed the Line before the signal was given. If delayed, the TTCS is deemed finished when it should have finished.
