If, after returning to the starting grid at the end of the formation lap a problem arises, the
following procedures shall apply :
a) If a car develops a problem that could endanger the start the driver must immediately
raise his hands above his head and the marshal responsible for that row must
immediately wave a yellow flag. If the race director decides the start should be delayed
the green lights will be illuminated two seconds after the abort lights are switched on, a
board saying “EXTRA FORMATION LAP” will be displayed and all cars able to do so must
complete a further formation lap whilst the car which developed the problem is moved
into the pit lane.
When leaving the grid to complete the extra formation lap all drivers must respect the
pit lane speed limit until they pass pole position.
The team may then attempt to rectify the problem and, if successful, the car may then
start from the end of the pit lane. Should there be more than one car involved their
starting order will be determined by the order in which they reached the end of the pit
Every time this happens the race will be shortened by one lap.
Why wasn't the race shortened by a lap yesterday then?
