3.8. Stopping of Free Practice, Official Qualifying Session or Race:
3.8.1.a. Should the need arise to stop free practice or official qualification, RED lights will be switched on at the Start Line and RED flags will be displayed at the Start Line and waved at all Marshals Signalling Posts around the track.
This is the signal for all drivers to immediately cease driving at racing speed and proceed slowly, without overtaking, and with maximum caution to the Pit Lane,
and being prepared to stop should the track be blocked. The BTCC Clerk may request the BTCC Doctor to proceed onto the track in the BTCC Medical Car, stopping if necessary at any incident.
3.8.1.b. Any car not returning to the Pits under its own power during the official qualifying session will only be allowed to participate further in that session at the discretion of the BTCC Clerk.
3.8.2. Should the need arise to stop a race, RED lights will be switched on at the Start Line and Red flags will be displayed at the Start Line and at all Marshals Signalling Posts around the Circuit.
This is the signal for all drivers to cease driving at racing speeds, to slow to a safe and reasonable pace and to return to the Starting Grid area which will automatically become a Parc Ferme area.
Cars may not enter the Pits unless directed to do so. Work on cars already in the Pits must cease when a race is stopped. The BTCC Clerk may request the BTCC Doctor to proceed onto the track in the BTCC Medical Car, stopping if necessary at any incident.
3.8.2. a Case A – Less than two laps completed by the Race leader.
The Race will be null and void. The race will restart from the original grid positions. Competitors unable to take the restart may be replaced by reserves who will start from the back of the grid in reserve order. Gaps on the grid should not be closed up. The length of the restarted race will be
determined by the BTCC Clerk.
3.8.2.b. Case B – More than two laps completed by the Race leader but less than 75%. The Race will restart from a grid set out by the finishing order of part one (as per MSA General Regulation G23). The result of the race will be the finishing order at the end of part two. The length of the restarted race will be determined by the BTCC Clerk.
3.8.2.c. If the race leader has completed more than 75% of the race distance, it may not be restarted and the results will be declared in accordance with MSA General Regulation G23.
3.8.2.d. Incidents occurring during the discounted part of a race (as per Sporting Regulations 3.8.2.a. and 3.8.2.b) will be dealt with in accordance with the Regulations. 3.8.2.e. In the event of a race being stopped, no team personnel are permitted on the grid until authorised to do so by a BTCC Official.
