General - experimental cockpit GPS system 22 October 2006
Trialled in Brazil, this safety feature is due to become mandatory next season. The system comprises three LEDs in the cockpit, representing the yellow, red and blue warning flags used by marshals. The aim is to avoid the risk of drivers not spotting flags being waved by marshals. The marshals will be able to signal race control when an incident occurs, allowing the race director to switch on the appropriate LED in cars as they pass through the affected area of track. In the case of a red flag, the red LED in all cars will come on simultaneously.
