To provide you with important information such as e.g. end of the driving time, a broken-down vehicle on the track or possible loss of grip due to contamination on the route, there are track marshals around the route equipped with colored flags. The Pistenclub orients itself on the flag signals that are common in motorsport. All flag signals are shown and explained in the drivers' briefing on the day of the event. Here, we have summarized all information about the flag signals for you.

Flag	Location	Meaning
	Start / Finish	Chequered flag End of the driving session. Finish the lap at a moderate speed - also to cool down your car, especially the brakes - and head for the pits at the end of the lap.
	Start / Finish Track marshal points to affected vehicle	Black flag You behaved unsportsmanlike, your vehicle has a technical problem visible from the outside or it is louder than the dB limit of the track. Drive into the pit at the end of the lap, further instructions are provided in the pit lane.
	Entire track	Red flag / Red signal lights Abort or interruption of the driving session. Finish the lap at a moderate speed - also to cool down your car, especially the brakes - and head for the pits immediately. Overtaking is absolutely forbidden.
	Entire track	Yellow flag / Yellow signal lights Danger due to a broken-down or damaged vehicle on or off the track. Reduce speed and be ready to brake. Overtaking is absolutely forbidden. Double waved flags The rules of the yellow flag / yellow traffic light apply. Great danger, the track may be completely or partially blocked or there are track marshals on the course. Extreme caution is required, be prepared to stop at any time. The maximum speed is 60 km/h. Full Course Yellow The rules of the yellow flag / yellow traffic light apply. A broken-down or damaged vehicle is secured during driving so that the driving time is not reduced. Full Course Yellow is only used on some courses and marked with the signal "FCY".
	Entire track	Green flag Danger is over. The overtaking ban is lifted. Continue driving at normal speed. Depending on the situation, the green flag can be omitted - if you have passed a very obvious danger spot, you can continue driving and overtaking even without the green flag. At the start of the first session, the green flag is usually shown to signal to all participants where the track marshals are located.
	Entire track	Blue flag A faster vehicle approaches from behind and wants to overtake. Let the vehicle pass at a place where overtaking is possible without danger. In addition, you can show this with an indicator - indicator left means: You stay left, the other vehicle can overtake on the right. In contrast to road traffic, at our events there is no right-hand drive requirement, i.e. overtaking is allowed on both the right and left. On some Italian racetracks the blue flags are very dark and can easily be confused with the black flag. If you have any doubts, please note that the black flag is only shown on the start and finishing straight.
	Entire track	White flag Slow vehicle (e.g. safety car or broken-down vehicle) on the track. Drive with foresight and overtake the vehicle with sufficient safety distance.
	Entire track	Red-and-yellow-striped flag Leaked resources, sand, gravel or other slippery contamination on the track. Track marshal pointing to the sky with the finger: Slippery surfaces possible due to e.g. beginning of rain. The red-and-yellow striped flag is only an indication, the speed does not need not be reduced.
