When Does Overtaking Become Legal Again After a MotoGP Yellow Flag?

The Green Signal Boundary

Passing a crash scene during a Grand Prix race does not immediately clear a rider to resume fighting for position. Under MotoGP yellow flag overtaking rules, competitors must slow down, exercise caution, and hold their track position until they pass the specific marshal post or light panel displaying a green signal. Even if the disabled bike or debris is already behind them, making a pass prior to that physical green marker remains an infringement.

Resolving an Inadvertent Pass

Riders who complete an overtake in a yellow-flagged sector can avoid sanction if they immediately recognize the error and deliberately surrender the position back to every competitor passed. If the position is not promptly returned, race officials communicate penalties directly to the rider via dashboard messages, with the compliance window starting the first time the machine crosses the finish line following the notification.

Signal Distinctions and Penalty Zones

Track regulations differentiate between a single yellow flag, which denotes a hazard beside the track, and a double yellow, which warns that an obstruction is partially or fully on the circuit itself. Both require identical caution and prohibit passing. Furthermore, if a yellow zone coincides with the designated Long Lap penalty route, riders are barred from serving their penalty until the area is cleared, and additional laps are added to their compliance window.

Official reference: danger ahead beside the track.
