Article B5.8.3
Race Shortened by One Lap Per Aborted Start
Chapter: B5
In Simple Terms
If the race start is aborted (called off and restarted) multiple times, the total number of laps in the race will be reduced by one lap for each aborted start that occurs. This ensures the race doesn't go on too long due to repeated restart attempts.
- Each aborted start procedure triggers a one-lap reduction in the race distance
- The reduction applies to the TTCS (Total Target Competition Starting) - the planned race length
- Multiple aborted starts result in multiple lap reductions
- This rule prevents excessively long races when there are repeated false starts or safety issues at the start line
Official FIA Text
For each Aborted Start procedure completed the TTCS will be shortened by one (1) lap.
