1/5

7. Observing yellow flags during free practice and qualifying

7.1 Double waved: Any driver passing through a double waved yellow marshalling sector must reduce speed significantly and be prepared to change direction or stop. In order for the stewards to be

satisfied that any such driver has complied with these requirements it must be clear that he has not

attempted to set a meaningful lap time, for practical purposes any driver in a double yellow sector

will have that lap time deleted.

7.2 Single waved: Drivers should reduce their speed and be prepared to change direction. It must be clear that a driver has reduced speed and, in order for this to be clear, a driver would be expected

to have braked earlier and/or discernibly reduced speed in the relevant marshalling sector.

Drivers should not overtake any car in a single waved yellow marshalling sector unless it is clear that

a car is slowing with a completely obvious problem, e.g. obvious accident damage or a deflated tyre.

8. In laps during qualifying and reconnaissance laps

8.1 In order to ensure that cars are not driven unnecessarily slowly on in laps during and after the end of qualifying or during reconnaissance laps when the pit exit is opened for the race, drivers must stay

below the maximum time set by the FIA between the Safety Car lines shown on the pit lane map.

You will be informed of the maximum time after the first day of practice.

9. Parc Fermé Cameras

9.1 To assist with the revised FIA Event procedures, the Parc Fermé cameras must be uncovered and operational at all times during the Event.

10. Operational personnel curfew

10.1 Boards warning anyone attempting to enter the paddock that the curfew is in operation will be placed immediately before the turnstiles at the appropriate times.

10.2 At this Event, Personnel will be permitted to enter the Paddock 30 minutes prior to the curfew to assist social distancing. No work is permitted to be undertaken until the curfew has ended.

11. Tyre Blanket Usage during Pit Stops in the Race

11.1 For reasons of safety, tyre blankets are not permitted in the Pit Lane at any time during the race.

12. Lapping during the race

12.1 The ISC requires drivers who are caught by another car about to lap him to allow the faster driver past at the first available opportunity. The F1 Marshalling System has been developed in order to

ensure that the point at which a driver is shown blue flags is consistent, rather than trusting the ability

of marshals to identify situations that require blue flags.

As it was at the end of last season the 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 flags 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.

It should be noted that the aim of using F1MS is to ensure consistent application of the rules,

additional instructions may also be given by race control when necessary.
