Race marshals use various F1 flags to take across
vital messages to the drivers. A GPS marshalling system is also
installed in the cars. Each driver's cockpit has a special display. As
the car passes through the particular track, the display lights up with
the relevant flag color. This helps the drivers identify messages easily
when traveling at high speed.
