Black and Orange Diagonal Flag

The Black and Orange Diagonal Flag in motorsport typically refers to the black flag with an orange circle in the center, commonly called the "meatball flag," which warns a driver that their car has a mechanical problem that could be dangerous and requires an immediate pit stop for inspection and repairs.

When race officials wave this flag at a specific driver, it means they've spotted something wrong with that car. The problem might be a loose body panel flapping in the wind, a damaged wing that's dragging on the track, fluid leaking from the engine or gearbox, or any part that looks like it might fall off. These issues don't just affect the driver receiving the flag—they can create hazards for everyone on the track.

The nickname "meatball flag" comes from its appearance: the orange circle on the black background resembles a meatball. This informal name is widely used in racing paddocks and commentary, making it easier to identify quickly during the fast-paced action of a race.

Unlike some flags that apply to all drivers on track, the black and orange flag is shown only to the specific driver whose car has the problem. Race marshals will typically display the flag along with the car's number so there's no confusion about who needs to respond. The driver is expected to acknowledge the flag and head to the pits within the next lap or two.

Once in the pit lane, the team must fix the issue before the car can return to the track. Sometimes the repair is quick—taping down a loose panel or removing a damaged piece. Other times, the problem might be serious enough that the car cannot continue racing safely, ending that driver's day.

Ignoring the black and orange diagonal flag carries serious consequences. Race stewards can impose time penalties, issue stop-and-go penalties, or even disqualify a driver who fails to respond. This strict enforcement exists because mechanical failures can cause crashes, debris on the racing surface, or fires—all situations that endanger drivers, track workers, and spectators.

Some confusion exists because a blue flag with a diagonal orange or yellow stripe serves a completely different purpose. That flag tells slower drivers that faster cars are approaching and they should allow them to pass. However, when people refer to the "black and orange diagonal flag" or "black and orange flag," they almost always mean the meatball flag indicating a mechanical problem.

This flag appears in most major racing series worldwide, including Formula 1, IndyCar, NASCAR, and sports car racing, though the exact design might vary slightly between organizations. The core meaning remains consistent: your car has a problem that needs immediate attention for safety reasons.
