Apparently to avoid confusion next year, the FIA have announced the following revised flag system for all F1 races:
yellow light blinking every second – hazard on track, no overtaking
Yellow light turning orange once every three seconds – marshals on track, slow down and be prepared to stop
Yellow light blinking once every second, but twice every third time – slippery track, caution
Yellow light with small orange lights winking three times each second – race stopped
Orange and yellow striped light – safety car
Yellow and orange striped light – track clear, proceed at racing speeds
Orange light with yellow checks, winking two times a minute – lapped driver must allow a faster car past
Yellow light with orange checks – warning over driving standards
Light off – flag system failure. use your initiative.
