Pre-race chaos wipes out McLaren’s Chinese GP before lights out!

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 shown. 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.

When the green lights are illuminated, the cars will begin the formation lap with the pole position driver leading. When the leading car returns to the grid all the cars must take up their grid positions, the pit exit lights will turn red and no cars may enter the track from the pit lane. Once the last car has taken up its grid position, the five red lights will be switched on one by one at one second intervals. The start will be signalled by the red lights being extinguished.
