Laps during Sprint Qualifying, Qualifying Sessons and Reconnaissance Lap(s), In order to ensure that cars are not driven unnecessarily slowly on in laps during and after the end of the Sprint Qualifying, Qualifying or during reconnaissance laps when the pit exit is opened for the Sprint and the Race, drivers must stay below the maximum time set by the FIA between the Safety Car lines shown on the pit lane map. Teams and Drivers will be informed of the maximum time after the Practice Session. For the safe and orderly conduct of the Event, other than in exceptional circumstances accepted as such by the Stewards, any driver that exceeds the maximum time from the Second Safety Car Line to the First Safety Car Line on ANY lap during and after the Sprint Qualifying, Qualifying session, including in-laps and out-laps or during reconnaissance laps when the pit exit is opened for the Sprint and the Race, may be deemed to be going unnecessarily slowly. For the avoidance of doubt, this does not supersede Articles 33.4 and 37.5 of the FIA Formula One Sporting Regulations, which apply to the entire Circuit, furthermore this includes the pit lane as well. Incidents will normally be investigated after the Sprint Qualifying, Qualifying session, the Sprint or the Race. 2. Parc Fermé The Parc Fermé cameras must be always uncovered and operational during the Event. 3. Post-Sprint Parc Fermé For the safe and orderly conduct of the Event, all Teams are requested to ensure they have three (3) mechanics per car available within the Parc Fermé area, or at the gate to the grid in the case of a car finishing in the top three, directly after the Sprint. As soon as a car is weighed and/or checked, it will be released to the Team mechanics, it must be immediately put on the trolley boards and returned to the Team garage. The car must stay on the trolley boards inside the garage with the wheels fitted until it is notified via the official messaging system, using the message “F1 - POST-SPRINT PARC FERME - WORK MAY COMMENCE AT ”, that all cars have been weighed and/or checked and Parc Fermé Conditions are lifted. Work on all cars may only be started following such notification via the official messaging system. 4. Lapping during Sprint and the Race The ISC requires drivers who are caught by another car to allow the faster driver past at the first available opportunity. The F1 marshalling system will be set to give a pre-warning when the faster car is within 3.0s of the car about to be lapped, this should be used by the team of the slower car to warn their driver he is soon going to be lapped and that allowing the faster car through should be considered a priority. When the faster car is within 1.2s of the car about to be lapped blue light panels will be shown to the slower car (in addition to blue light panels, blue cockpit lights and a message on the timing monitors) and the driver must allow the following driver to overtake at the first available opportunity. 1 5. Article 55.15 SR “In order to avoid the likelihood of accidents before the safety car returns to the pits, from the point at which the lights on the car are turned out drivers must proceed at a pace which involves no erratic acceleration or braking nor any manoeuvre which is likely to endanger other drivers or impede the restart”. 6. ERS safety check after covers off In accordance with the provisions of Article 40.2 k of the Sporting Regulations, as work required by the Technical Delegate; Each morning, immediately after covers are removed when the cars are under parc fermé conditions (Articles 40.7 and 40.8), all Teams must connect the umbilical to their cars and start a telemetry data logging for the sole purpose of checking the car ERS safety status. 7. Pit Lane Safety Article 26.3 of the Sporting Regulations states: “Save where these Sporting Regulations require otherwise, pit lane and track discipline and safety measures will be the same for all Free Practice sessions, the Sprint Qualifying, the Qualifying session, the Sprint as for the Race.” Additionally, Article 34.13 of the Sporting Regulations states: “Team personnel are only allowed in the pit lane immediately before they are required to work on a car and must withdraw as soon as the work is complete.” For the safe and orderly conduct of the event, in the context of the race only, the requirements of Article 34.13 are considered to apply until such time as all cars able to do so have completed the Race and have entered the designated Parc Ferme area. Following the end-of-session signal, described in Article 59.1, and when the Race Director considers it safe to do so, the message “ALL PASS HOLDERS MAY ACCESS THE PIT LANE” will be sent to all competitors using the official messaging system; this being the signal to all competitors that the requirements of Article 34.13 are no longer applicable, and thus holders of passes not valid for access to the Pit Lane (i.e. passes other than those marked “Pit Lane” or “Pit Lane All Times”) may enter the pit lane. Competitors are reminded that in accordance with the International Sporting Code, Article 9.15.1 “The Competitor shall be responsible for all acts or omissions on the part of any person taking part in, or providing a service in connection with, a Competition or a Championship on their behalf, including in particular their employees, direct or indirect, their Drivers, mechanics, consultants, service providers, or passengers, as well as any person to whom the Competitor has allowed access to the Reserved Areas. 8. Lap times in each Practice Session, Sprint Qualifying, Qualifying session, Sprint and the Race Only lap times which have been completed on the track will be included for the purpose of any classification. 9. Finishing the Sprint and the Race For the purpose of finishing the Sprint and the Race, pursuant to Article 59.1 of the FIA Formula One Sporting Regulations, the “Line” referred to will be the Control Line on the track and not in the Pit Lane. 2 Event Specific Instructions 10. Marshalling System 10.1 A car entering the Pit Lane will be subject to the marshalling state (i.e. yellow flag or double yellow flag) of the associated sector until it passes the blue line marked on the image below. ![Extracted image from page 4](images/race-directors-event-notes-v2_p4_img2.jpeg) 10.2 A car leaving the Pit Lane will be subject to the marshalling system state i.e. yellow flag or double yellow flag of the sector into which it is emerging after it passes the blue line marked on the image below. ![Extracted image from page 4](images/race-directors-event-notes-v2_p4_img1.jpeg) 11. Specific Technical Procedures Please note that the FIA have introduced an Appendix Index File which contains all the relevant and active Appendix documents, Technical and Sporting Directives. The latest version of this Index file (“2025 Formula 1 Appendix – iss 13 – 2025-10-10.xlsx”) and all relevant documents can be found on the FIA SFTP site. Competitors are hereby required to ensure compliance with these directives for the safe and orderly conduct of the Event. 12. Support Races team barrier placement and movements Team barrier placement prior to and during all support category practice sessions and races: No more than ten (10) meters from the garages. Please ensure that your pit stop gantry arms are moved back towards the garage during all support category activities. Support Category competition vehicles will be released from the marshalling area no earlier than 15 minutes prior to the opening of Pit Exit for their respective sessions. 13. Practice starts 13.1 During the Free Practice session and the reconnaissance laps prior to the Sprint and the Race, practice starts may be carried out in the merging lane to the left-hand side to fast lane, using one of the painted grid boxes shown in the image below. Cars queuing to perform a practice start must keep be in the merging lane, to allow sufficient space for cars not wishing to do a practice start to pass. 3 ![Extracted image from page 5](images/race-directors-event-notes-v2_p5_img3.jpeg) 13.2 For the avoidance of doubt, practice starts may not be carried out during the Sprint Qualifying and the Qualifying Session. 13.3 Practice starts after the Free Practice will be performed according to Article 38.3 of the Sporting Regulations. 13.4 If the Free Practice session is resumed with less than 2 minutes remaining, for the purpose of facilitating practice starts on the grid as provided for in Article 38.3 of the Sporting Regulations, any car wishing to leave the pit lane must proceed down the pit lane without undue delay and exit the pit lane without leaving a significant gap to the car ahead. 14. Article 34.8 Sporting Regulations (…) Any car(s) driven to the end of the pit lane prior to the start or re-start of a Free Practice session, Sprint Qualifying or Qualifying session must form up in a line in the fast lane and leave in the order they got there (…) It is noted that a car will be considered to be “in the fast lane” when a tyre has crossed the solid white line separating the fast lane from the inner lane, in this context crossing means that all of a tyre should be beyond the far side, with respect to the garages, of the line separating the fast lane from the inner lane. ![Extracted image from page 5](images/race-directors-event-notes-v2_p5_img4.jpeg) For the avoidance of doubt, ISC Appendix L, Chapter IV, Article 5b) states that: Once a car has left its garage or pit stop position it should blend into the fast lane as soon as it is safe to do so, and without unnecessarily impeding cars which are already in the fast lane. Thus, after the start or re-start of the Free Practice session, Sprint Qualifying or Qualifying session, if there is a suitable gap in a queue of cars in the fast lane, such that a driver can blend into the fast lane safely and without unnecessarily impeding cars already in the fast lane, they are free to do so. Furthermore, it is noted that during the Free Practice session, Sprint Qualifying or Qualifying session a car driving in the inner lane, parallel to the fast lane, will not be considered to have blended into the fast lane at the earliest opportunity. 4 Additionally, ISC Appendix L, Chapter IV, Article 5d) states that: Cars in either the fast lane or working lane may not overtake other cars in the fast lane except in exceptional circumstances. In this context a “stopped car” is one which has an obvious mechanical problem. 15. Lines at the Pit Entry and Pit Exit 15.1 In accordance with Chapter 4, Articles 4 and 6 of Appendix L to the ISC drivers must follow the procedures at pit entry and pit exit. 15.2 Pertaining to Chapter 4, Article 4 of Appendix L to the International Sporting Code any driver passing to the left hand side of the bollard at pit entry will be considered as entering the pit lane. ![Extracted image from page 6](images/race-directors-event-notes-v2_p6_img5.jpeg) 15.3 During the reconnaissance laps prior to the Sprint and the Race drivers are allowed to cross the white line separating the pit exit road from the circuit. 16. Stopping Sprint Qualifying or the Qualifying Session For the safe and orderly conduct of the event, should any period of the Sprint Qualifying or Qualifying Session be stopped with less than 90 seconds remaining, the Race Director with the agreement of the Stewards may decide that the relevant period of the Sprint Qualifying or the Qualifying session will not be resumed, i.e. that part of the competition will be stopped. 17. Post Sprint Qualifying and Qualifying Session drivers weighing Any driver who as finished participating in the Sprint Qualifying or Qualifying Sessions after SQ1/ Q1 and SQ2/Q2 must proceed through the pit lane directly to the FIA scales immediately after they have returned to their team’s garage. The drivers may not drink anything or do anything which increases their weight before it is recorded by the FIA. Any driver who stops on the track during the Sprint Qualifying or the Qualifying sessions and is not required to visit the Medical Centre must proceed to the FIA scales to get their weight recorded before returning to his team. Drivers who finish within the top 10 must proceed to the FIA scales immediately when out of their cars without contact with any other person. 18. DRS during Free Practice session, Sprint and the Race DRS Detection will be automatically disabled in each individual zone if any of the light panels in that zone are displaying yellow.

Track Limits In accordance with the provisions of Article 33.3 of the Sporting Regulations, the white lines define the track edges. During Sprint Qualifying, Qualifying, the Sprint and the Race, each time a driver fails to negotiate the lap within the track limits, this will result in that lap time being invalidated by the Stewards.

Unsafe or Unknown ERS Status If the status of the ERS changes to unsafe or unknown, the relevant team will be required to send mechanics to the race control door area, in the pit lane side. They will then be picked up by car to be brought to their car (depending on the location of the car, they can be taken during the session). 22.
