Flags

		Chequered Flag Indicates the end of a race
		Red Flag All racing to stop immediately. All competitors to proceed to the finish line.
		Black Flag Together with competitor's number in white on black board, informs the driver that he must stop at his pit at the end of the lap.
		Yellow Flag Danger! Competitors must slow down, and maintain their positions.
		Blue Flag Informs a competitor that he is about to be overtaken
		Black / Orange Disc Together with competitor's number informs driver that he has mechanical problems, and that he must stop at his pit at the end of the lap.
		Green Flag "All Clear" after a dangerous situation. May also be used to start warm-up or practice sessions.
		White Flag Attention! Slow-moving traffic on the circuit. e.g. emergency vehicles
		Yellow & Red Stripes Deterioration of track surface due to oil or water.
		Black & White Together with competitor's number warns the driver of unsportsmanlike behaviour

To ensure adequate supervision of a racing circuit, the clerk of the course and/or Assistant and the observation posts, rely largely on the use of safety signals to:

a) contribute to the safety of the competitors

b) enforce the regulations

Signals are given in day-time by different coloured flags, possibly aided by lights. At night-time or in conditions of poor visibility the flags should preferably be replaced by lights and reflective panels, but all drivers must be aware of this beforehand. Yellow lights at each post are obligatory for events run at night.

Flags

The minimum size of signal flags is 60cm by 80cm

Flags will be used during both practice and the race itself and will have the same meaning. They shall be respected by the competitors at all times. Any competitor failing to acknowledge or act upon a signal conveyed to him/her personally, or to a group of competitors of which he/she forms a part, engaged in a practice or a race, by an authorised official using any of the flag or light signals listed herein, shall be guilty of an offence which may be dealt with by the Clerk of the Course in terms of GCR 156.

Start

Shall be given by the MSA flag or red lights. In the latter case the red lights shall normally remain lit for between 4 and 7 seconds before being extinguished. In the case of a start by flag, the signal to start will be the lowering of the flag which, for standing starts, should not be raised until all vehicles are stationary and in no case for more than 10 seconds.

Finish

A Black and white chequered flag, usually waved.

Red Flag

Shown waved under direction of the Clerk of the Course, at all marshal points around the circuit, (except that immediately prior to the incident which shall show double waved yellow flags), indicates that the practice or race has been terminated and all competitors must stop their practice or race immediately and proceed to the pits, or place stipulated by the SR's for the event, exercising extreme caution and being prepared to stop at any time if necessary, It is not permitted for any competitor to pass another once the practice or race has been terminated by the display of the waved red flag.

Black Flag

Shown by the Clerk of the Course together with a number board indicated to the competitor whose number is shown that he/she must stop at the pits at the end of the lap.

Black & White Flags divided diagonally into black and white halves:

Shown by the Clerk of the Course together with a number board indicated to the competitor whose number is shown that he is warned for unsportsmanlike behaviour.

Black Flag with Orange disk

Shown together with the number board indicated that the vehicle concerned has a potentially dangerous defect and must stop at the pits at the end of that lap.

Yellow Flag

Indicates danger, either temporary or permanent, whatever its nature. A waved yellow flag denotes a dangerous situation in the sector following the marshal post concerned. Drivers will be warned of any new danger occurring in the same sector by waving the yellow flag for two laps and then displaying it stationary for two laps, after which it will be withdrawn, even if the cause of the danger has not been removed.

Drivers are to be instructed, either by hand or flag, to use the unobstructed portion of the track, and if the obstruction is very serious, 2 yellow flags may be waved at the same post. In the case of a total obstruction, two yellow flags may be used prior to the Clerk of the Course stopping the race.

When an obstruction occurs in a sector and a yellow flag is being waved, the preceding post will display a stationary yellow flag to warn drivers in good time of the danger. If 2 yellow flags are being waved, the preceding post will show two stationary flags.

Should a danger such as debris extend beyond the accident or obstruction into another sector, the post in this sector will also display a yellow flag. Otherwise, if this sector is clear, a green flag will be displayed.

Competitors passing any yellow flag must slow down, maintaining their position relative to other competitors and being prepared to stop if so instructed by a competent Official.

DRIVERS MUST, AS SOON AS THEY HAVE PASSED A YELLOW FLAG (BE IT WAVED OR MOTIONLESS) SLOW DOWN, BEING PREPARED TO STOP IF NECESSARY AND KEEP THEIR RESPECTIVE POSITIONS AND MAY NOT OVERTAKE UNTIL THEY HAVE PASSED A GREEN FLAG.

Green Flag

Shown motionless denotes:

	a)	when shown on the first lap of practice or outlap of a race that the sector being entered is clear; or
	b)	that the sector controlled by the yellow flags following a dangerous situation is being exited and racing may continue once the competitor has passed the green flag; or
	c)	used to start a warm up or parade lap or practice session under direction of the Clerk of the Course.

Shown waved at the start/finish line denotes that a Safety Car intervention has ended and racing may continue once the competitor passes the Green flag at the start/finish line.

Yellow Flag with Red Stripes

Indicates a deterioration of surface due to oil, water, etc. This flag can also be used to inform drivers of either a pool of water large enough to create aquaplaning, or that due to a local shower, drivers/riders are about to pass from a dry to a slippery surface: this being the case, the flag will be displayed accompanied by a hand pointed at the sky. Shall be displayed for 4 laps, or until the surface returns to normal.

White Flag

Denotes either a service vehicle (ambulance etc) or a competing car moving slowly. It should be waved while the vehicle is in a sector and then held stationary while the vehicle reaches the end of the next sector, after which it should be withdrawn. Should the vehicle stop on the track, the white flag must be replaced immediately by yellow flags.

Blue Flag

To be shown:

	a)	in cases of obvious obstruction by a competitor;
	b)	when slower vehicles are being overtaken by the leader;
	c)	when a faster vehicle making up time is working its way through the field

It is not necessary to show the Blue flag:

	a)	during the first lap of the race when competitors are still grouped together
	b)	when two or more drivers are racing wheel to wheel over several laps
	c)	when, by his actions, a driver is aware he is about to be overtaken

The Blue flag should always be used with discretion, bearing in mind that in the wet during bad visibility it is often the best means of warning a competitor he is about to be overtaken.
