People who watch the Formula One racing game would have seen marshals showing flags to the drivers. Do you know the flag communicates a message to the drivers? There are several standard flags, and it will be seen around the racing track. The GPS marshalling system is a special display found in the cockpit of each driver. It lights up with suitable flag colour when the driver has passed through the affected section. It is hard for the driver to view the flag shown by the Marshal. They will be driving the car at utmost speed, and it is hard for them to keep an eye on the flags. The system present in the car helps the driver to identify the message and control the vehicle accordingly.
Chequered Flag: The chequered flag indicates that the race session is completed. During qualifying and practice sessions, the chequered flag will be waved at the estimated time. It will be shown to the winner who wins the race while conducting the race. It will be displayed in other cars that follow the winner at a particular time.
Yellow Flag: It means danger. If there is a stranded car ahead, the yellow flag will be shown. It will warn the driver to slow down. If they have waved a single yellow flag, the driver should slow down. When they have waved double or two yellow flags, the driver should be ready to slow down anytime and stop the car if necessary. They are not allowed to overtake at this moment.
Green Flag: It means all roads are clear. The driver has cleared the possible prohibitions and danger points when the yellow flags were lifted.
