38.6 When the one minute signal is shown, engines should be started and all team personnel must leave the grid by the time the 15 second signal is given taking all equipment with them. If any driver needs assistance after the 15 second signal he must raise his arm and, when the remainder of the cars able to do so have left the grid, marshals will be instructed to push the car into the pit lane. In this case, marshals with yellow flags will stand beside any car (or cars) concerned to warn drivers behind.

38.7 When the green lights are illuminated, the cars will begin the formation lap with the pole position driver leading. When leaving the grid all drivers must proceed at a greatly reduced speed until clear of any team personnel standing beside the track. Marshals will be instructed to push any car (or cars) which remain on the grid into the pit lane by the fastest route immediately after cars able to do so have left the grid. Any driver being pushed from the grid may not attempt to start the car and must follow the instructions of the marshals.

38.8 During the formation lap practice starts are forbidden and the formation must be kept as tight as possible.

38.9 Overtaking during the formation lap is only permitted if a car is delayed when leaving its grid position and cars behind cannot avoid passing it without unduly delaying the remainder of the field. In this case, drivers may only overtake to re-establish the original starting order. Any driver who is delayed leaving the grid may not overtake another moving car if he was stationary after the remainder of the cars had crossed the Line, and must start the race from the back of the grid. If more than one driver is affected, they must form up at the back of the grid in the order they left to complete the formation lap. If the Line is not situated in front of pole position, and for the purposes of this Article as well as Articles 38.10 and 40.16, it will be deemed to be a white line one metre in front of pole position.
Either of the penalties under Articles 16.3a) or b) will be imposed on any driver who, in the opinion of the Stewards, unnecessarily overtook another car during the formation lap.
