installed or will flow around the Circuit in both directions as adjacent Marshals Posts display both their waved yellow Signal and“ SC” board where there are no panels.
2.5. Flashing yellow lights may also be used at the start-line and at other points around the Circuit.
2.6. All competing Vehicles, when notified of the Safety Car intervention( by the flag Signals,“ SC” boards, or by any other means) will reduce speed and line up behind the Safety Car no more than 5 car lengths apart and maintaining the same speed as it. Overtaking or overlapping of any other competing Vehicle during a Safety Car intervention is forbidden. Overtaking of a Safety Car is forbidden unless the particular Competitor concerned is signalled to overtake the Safety Car by the observer in the Safety Car. Any overtaking or overlapping during the Safety Car intervention will be deemed a breach of signals, Ch. 2 App. 12 Art. 1.2. b
2.7. When ordered to do so by the Clerk of the Course, the observer in the Safety Car will wave past any Vehicles between the Safety Car and the Race leader. These Vehicles will continue at reduced speed and without overtaking until they reach the line of Vehicles behind the Safety Car.
2.8. While the Safety Car is in operation competing Vehicles may enter the pit lane but may only rejoin the Track when signalled to do so and not when the Safety Car and the line of Vehicles following it are about to pass or are passing the pit exit. A Vehicle re-joining the Track must proceed at an appropriate speed until it reaches the end of the line of Vehicles behind the Safety Car.
2.9. The Safety Car will remain in operation until at least the majority of competing Vehicles on the Circuit are lined up behind it.
2.10. When the Clerk of the Course calls in the Safety Car it will extinguish the yellow / amber flashing lights prior to exiting the Circuit. This would normally be such that a minimum of 25 % of a lap for Circuits over 2 miles and 50 % of a lap for Circuits under 2 miles should be completed by the Safety Car with its lights extinguished.
2.11. Following the Safety Car extinguishing its lights and prior to passing the green Signal the Race leader will dictate the pace and if necessary fall more than five car lengths behind the Safety Car. 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 Vehicle are extinguished Drivers must proceed at a pace which will not lead to the Safety Car being overtaken before it has entered the pit road, involves no erratic acceleration or braking nor any other manoeuvre which is likely to either endanger other Drivers or impede the restart.
2.12. As the Safety Car is entering the pit entry road the green Signal will be displayed at the Start / Finish line and the“ SC” board withdrawn. Following this display of the start Signal yellow Signal and“ SC” boards at the Signalling Posts will be withdrawn and be replaced with a‘ waved green’ Signal for one lap. The‘ waved’ green Signal will be displayed simultaneously by Race Control where light panels are installed or will flow around the Circuit in both directions as an adjacent post displays their‘ waved’ green Signal where there are no panels. This system may be supplemented by a message being simultaneously broadcast to all Signalling Posts if such a communication system is available. Overtaking or overlapping remains strictly forbidden until the start Signal at the Start / Finish line is passed. Any overtaking or overlapping after the Safety Car signals have been withdrawn and before passing the Green Signal at the Control Line will be deemed to be gaining an advantage( Ch. 2 Annexe A Art. 1.3).
2.13. Each lap covered while the Safety Car is in service will be counted as a Race lap unless specified to the contrary in Championship Regulations.
2.14. Under certain circumstances the Clerk of the Course may ask the Safety Car to use the pit lane. In this case and provided its yellow / amber lights remain illuminated all Vehicles must follow it into the pit lane without overtaking. Any Vehicle entering the pit lane under these circumstances may stop at its designated garage area.
2.15. Should it be necessary to stop a Race during a Safety Car deployment the Safety Car with all competing Vehicles following will pass through the Red Signal at the Start / Finish line complete one further lap at reduced speed and then once the Safety Car comes to a stop at a position indicated by the Safety Car observer( which will usually be either the grid or Parc Fermé), all competing Vehicles must stop behind it unless otherwise directed.
