Motorsport Flag and Penalty Interpreter
Motorsport Flag and Penalty Interpreter
What each racing flag published in Appendix H to the FIA International Sporting Code actually means, in the FIA’s own words, with the two that mean different things in practice and in the race separated out. Three of them are addressed to one named car and carry a penalty or a warning.

|---|---|---|
| Red | waved at the start line to stop a session or the race | until the session or race is stopped |
| Yellow, single or double waved | waved | normally only at the marshal post immediately preceding the hazard, though the Clerk of the Course may order more than one |
| Yellow with red stripes | motionless | “for at least (depending on the circumstances) 4 laps unless the surface returns to normal beforehand” |
| Light blue | normally waved; motionless to a car leaving the pits if traffic is approaching | while it applies |
| Black | motionless, with the car’s number on a board | “this flag should not be shown for more than four consecutive laps” if the driver fails to comply |
| Black with an orange disc | motionless, with the number board | the car “must stop at his pit on the next lap” |
| Black and white divided diagonally | motionless, with the number board | “shown once only” |
| Green | waved | at the marshal post immediately after the incident; it is what ends the overtaking ban |
Twelve flags, three of them addressed to one car, two of them session-dependent
This page is about motorsport — circuit racing in cars — whose international rules are the Fédération Internationale de l’Automobile’s: the International Sporting Code and its appendices for the sport as a whole, and a separate set of Sporting Regulations for each championship. Every figure below is printed with the regulation, the issue and the date it was read from, because motorsport regulations are not merely revised between seasons — they are reissued several times within a season and renumbered between editions, and a rule quoted without its issue will be wrong for somebody. The FIA published nine issues of the 2026 Formula 1 Sporting Regulations between October 2024 and October 2026.
Racing flags are published, in words, in Appendix H to the FIA International Sporting Code, which is the appendix on the supervision of the route. The edition read for this page is the 2026 one, published 23 June 2026, and the meanings below are quoted from Articles 2.5.4.1 and 2.5.5 of it. Only that one edition was read, so nothing here says a meaning is unchanged from any earlier year — and that caution is not theatre, because Appendix H is reissued like every other FIA document.
The appendix divides the flags by who shows them. Articles 2.5.4.1 (a) to (f) are the flags used by the Clerk of the Course: the national flag that may start the race, the red flag that stops a session, the chequered flag that ends one, and three that are addressed to a single named car. Articles 2.5.5 (a) to (g) are the flags used at marshal posts: red again, the single and double waved yellows, the yellow with red stripes, the light blue, the white and the green.
Three of the twelve are the penalty and warning flags, and what makes them different is that they name a car. The black and white flag divided diagonally “should be shown once only and is a warning to the driver concerned for unsportsmanlike behaviour or for an action which may result in a penalty if repeated” — a warning, not a penalty. The black flag with an orange disc is not a penalty either: it means “his car has mechanical problems likely to endanger himself or others” and that he “must stop at his pit on the next lap”, after which, “when the mechanical problems have been rectified to the satisfaction of the chief scrutineer, the car may rejoin the race”. The black flag is the serious one, and the appendix is careful about who may show it: “The decision to show this flag rests solely with the Stewards, and the team concerned will immediately be informed of the decision.” All three “should be shown motionless and accompanied by a black board with a white number”, so a driver who sees one without a number beside it is not the driver being addressed.
Two flags mean different things depending on the session, which is the reason this page asks which session you are in. Appendix H says it outright of the light blue flag — “It has different meanings during practice and the race” — where in practice it tells you “A faster car is close behind you and is about to overtake you”, and in the race it is shown to a car about to be lapped, whose driver “must allow the following car to pass at the earliest opportunity”. The double waved yellow is the other: it carries an extra instruction in practice and qualifying, that “it must be evident that a driver has not attempted to set a meaningful lap time”, which the article glosses as abandoning the lap — “this does not mean he has to pit as the track could well be clear the following lap”. In the race there is no lap to abandon and the instruction has nothing to attach to.
Two details that catch people out. First, the overtaking ban under yellows does not end where the yellows end: “Overtaking is not permitted between the first yellow flag and the green flag displayed after the incident”, so it is the green flag that releases the field. Second, the same colour means two things depending on whether it is moving. A waved yellow is about a hazard; a motionless yellow with red stripes is about grip, “a deterioration of grip due to oil or water on the track in the area beyond the flag”, and it stays out “for at least (depending on the circumstances) 4 laps unless the surface returns to normal beforehand” — and, unusually, “It is not, however, necessary for the sector beyond where this flag is being shown to show a green flag.”
What this page is not. Appendix H is a recommendation to organisers for supervising the route, not a championship’s disciplinary code: it says what a flag means, not what penalty follows a breach, and the penalties live in each championship’s own sporting regulations. Nothing here is advice about driving, and nothing here replaces a drivers’ briefing — the Race Director’s Competition Notes for a single event run to some fourteen thousand characters of circuit-specific instruction on top of all of this. Formula One also signals most of these messages on FIA light panels as well as with flags, and the virtual safety car is a light-panel message with no flag of its own at all: that one is on the race suspension and virtual safety car interpreter.

Frequently asked questions
What does a double waved yellow flag mean?
“Reduce your speed significantly, do not overtake, and be prepared to change direction or stop”, because “There is a hazard wholly or partly blocking the track and/or marshals working on or beside the track” — Article 2.5.5 b) of the 2026 Appendix H. In free practice and qualifying it also requires that “it must be evident that a driver has not attempted to set a meaningful lap time”, which means abandoning the lap.
When can you overtake again after a yellow flag?
At the green flag, not at the end of the yellow sector. Article 2.5.5 b): “Overtaking is not permitted between the first yellow flag and the green flag displayed after the incident.” The green flag is waved “at the marshal post immediately after the incident that necessitated the use of one or more yellow flags”.
What is the difference between a black flag and a black flag with an orange disc?
One is disciplinary and one is mechanical. The black flag tells a named driver to stop at his pit, and “The decision to show this flag rests solely with the Stewards”. The orange disc means the car “has mechanical problems likely to endanger himself or others” and must stop at the pit on the next lap, after which it may rejoin once the problem is rectified “to the satisfaction of the chief scrutineer”.
What does the yellow flag with red stripes mean?
Loss of grip, not a hazard. Shown motionless, it informs drivers “that there is a deterioration of grip due to oil or water on the track in the area beyond the flag”, and it stays out “for at least (depending on the circumstances) 4 laps unless the surface returns to normal beforehand”. No green flag is needed afterwards.
Why does the light blue flag have two meanings?
Because Appendix H gives it two. Article 2.5.5 e) states that “It has different meanings during practice and the race”: in practice “A faster car is close behind you and is about to overtake you”, and in the race it is shown to a car about to be lapped, which “must allow the following car to pass at the earliest opportunity”. Shown motionless, it warns a car leaving the pits that traffic is approaching.

Article 2.5.4.1 (a) to (f) are the flags used by the Clerk of the Course and Article 2.5.5 (a) to (g) those used at marshal posts; the meanings are written out as plain text in both languages, not drawn as pictures, which was checked because a flag table is the obvious candidate for being an image. Only this one edition was read, so nothing in this batch claims a flag meaning is unchanged from any earlier year.

Read specifically to find a named circuit’s pit lane length and pit lane speed limit, and it contains neither — no lap distance, no race distance, no pit lane length, no speed limit, no DRS zones. It does define the Safety Car lines and the pit entry, states that the finish is taken at “the Control Line on the track and not in the Pit Lane”, and several of its items refer to “the image below”, so any pit lane dimension that is published at all appears to be published as a drawing.
