Flags
| Marshals at various points around the circuit are
issued with a number of standard flags, all used to communicate vital
messages to the drivers as they race around the track. A special display
in each driver’s cockpit - known as a GPS marshalling system - also
lights up with the relevant flag colour, as the driver passes the
affected section of track. Travelling at such high speeds, it may be
hard for a driver to spot a marshal’s flag and this system helps them
identify messages from race control more effectively. Chequered flag Indicates to drivers that the session has ended. During practice and qualifying sessions it is waved at the allotted time, during the race it is shown first to the winner and then to every car that crosses the line behind him. Yellow flag Indicates danger, such as a stranded car, ahead. A single waved yellow flag warns drivers to slow down, while two waved yellow flags at the same post means that drivers must slow down and be prepared to stop if necessary. Overtaking is prohibited. Green flag All clear. The driver has passed the potential danger point and prohibitions imposed by yellow flags have been lifted. Red flag The session has been stopped, usually due to an accident or poor track conditions. Blue flag Warns a driver that he is about to be lapped and to let the faster car overtake. Pass three blue flags without complying and the driver risks being penalised. Blue lights are also displayed at the end of the pit lane when the pit exit is open and a car on track is approaching. Yellow and red striped flag Warns drivers of a slippery track surface, usually due to oil or water. Black with orange circle flag Accompanied by a car number, it warns a driver that he has a mechanical problem and must return to his pit. Half black, half white flag Accompanied by a car number, it warns of unsporting behaviour. May be followed by a black flag if the driver does not heed the warning. Black flag Accompanied by a car number, it directs a driver to return to his pit and is most often used to signal to the driver that he has been excluded from the race. White flag Warns of a slow moving vehicle on track. |
