MotoGP Flags and Lights Explained: Complete Beginner’s Guide
During a MotoGP™ Grand Prix, riders must constantly monitor the flags and lights displayed around the circuit. These signals provide essential information about track conditions, incidents, overtaking restrictions, race interruptions, and instructions from Race Direction.
Flags are displayed by marshals at designated posts around the circuit. They may be shown motionless or waved, and the way a flag is displayed can affect its meaning.
Failure to obey flag signals can lead to penalties ranging from a warning or fine to a long-lap penalty, position penalty, time penalty, ride-through, disqualification, loss of championship points, suspension, or exclusion.

Black Flag — Disqualification
The black flag means that a rider has been disqualified.
It is normally displayed at the marshal posts together with the rider's race number. Once shown, the rider must enter the pits at the end of the current lap and cannot continue the session or race.
The rider's team is normally notified before the flag is displayed.
A black flag is one of the most serious instructions a rider can receive because it removes the rider from the competition.
Black Flag with Orange Disc — Mechanical Problem
The black flag with an orange disc tells a rider that their motorcycle has a mechanical problem that could create a danger to the rider or other competitors.
The rider must leave the racing line and return to the pits as soon as it is safe to do so.
This signal is particularly important when a motorcycle is leaking fluids, has a damaged component or has another mechanical problem that could affect safety.
White Flag — Bike Change Permitted
The white flag has a particularly important role in MotoGP when weather conditions change.
When the white flag is waved during a race, it indicates that riders are permitted to change motorcycles.
This is associated with a flag-to-flag race, where changing weather conditions make different motorcycle settings or tyres necessary. For example, a race that started in dry conditions may become wet enough for riders to switch to a motorcycle equipped for wet-weather tyres.
The white flag therefore tells riders that the pit lane is open for a motorcycle change when the relevant race procedure allows it.
White Flag with Red Cross and Yellow/Red Striped Flag — Rain
A white flag with a diagonal red cross, shown together with the yellow- and red-striped flag, indicates that there is rain or a wet section of track in the area controlled by that marshal post.
These flags warn riders that grip may be reduced.
The warning can be especially important when rain is falling in only one part of the circuit while other sections remain dry.
Blue Flag — Faster Rider Approaching
The blue flag, when waved, tells a rider that another rider is approaching and should be allowed to pass.
During a race, it commonly indicates that a rider is about to be lapped.
The rider receiving the blue flag must not unnecessarily obstruct the faster rider and should allow the pass to happen safely.
Blue flags can also be shown during practice sessions when a faster rider is approaching. In that situation, the slower rider should maintain a predictable line and allow the faster rider to pass safely.
A blue flag may also be displayed to a rider leaving the pit lane when other traffic is approaching on the circuit.
Chequered Black and White Flag — Session Finished
The chequered flag marks the end of a race or track session.
It is displayed at the finish line and waved as riders cross the line.
In a race, the winner is the first rider to receive the chequered flag after completing the required race distance or duration, subject to the official classification.
The checkered flag is also used to signal the end of practice and qualifying sessions.
However, seeing the chequered flag does not necessarily mean a rider can immediately slow down anywhere on the circuit. Riders must continue to follow the instructions and procedures applicable after the session.
Yellow Flag — Danger Ahead
The yellow flag warns riders of a hazard ahead.
When a yellow flag is waved at a marshal post, riders must slow down and be prepared to stop if necessary. Overtaking is prohibited in the affected area until the appropriate green signal is displayed.
Possible hazards include:
- A crashed motorcycle or rider
- Debris on the circuit
- A stranded motorcycle
- A vehicle or recovery equipment near the track
- Marshals working in a dangerous area
- Other unexpected hazards
Yellow flags can be displayed at individual marshal posts, meaning the danger may be limited to a particular section of the circuit.
Yellow Flags at the Start
Yellow flags may also be used around the starting grid when the start procedure is interrupted or delayed.
Riders must pay close attention to the signals given by Race Direction because the procedures can differ depending on the circumstances.
Penalties for Yellow-Flag Overtaking
Overtaking under yellow flags is treated as a serious safety infringement.
In practice or qualifying, a rider may have a lap time cancelled when an infringement occurs.
During a race, the rider can be required to surrender positions or receive another penalty determined under the applicable regulations.
This is why riders must react immediately when they see a yellow flag.
Red Flag — Race or Session Stopped
The red flag means that the race or track session has been interrupted.
When the red flag is displayed, riders must reduce speed and return to the pits or follow the instructions given by Race Direction.
Red flags can be used when continuing the session would be unsafe. Examples include:
- A serious crash
- Dangerous track conditions
- Heavy rain
- Significant debris
- Problems with circuit infrastructure
- Other circumstances requiring the track to be cleared
Red lights around the circuit may also be illuminated when the session is stopped.
A red flag does not necessarily mean that the race has been permanently cancelled. Depending on the regulations and circumstances, a race may be restarted after the track has been made safe.
Red Lights — Race Start
The red starting lights are one of the most recognizable signals in MotoGP.
Before the start of a race, the red lights on the starting gantry are illuminated. They remain on for a short period before going out.
When the lights go out, the race begins.
This is the moment riders launch from their grid positions and accelerate towards the first corner.
At the end of practice and warm-up sessions, red lights may also be used at the finish line to indicate that the session has ended.
Green Light — Pit-Lane Exit Open
A green light at the pit-lane exit indicates that riders are permitted to leave the pit lane and enter the circuit, subject to the session and applicable procedures.
It can be used at the beginning of practice, warm-up, and other track activities.
Riders must still check for approaching traffic before entering the circuit.
Green Flag — Track Clear
The green flag indicates that the track is clear following a previous hazard.
It is especially important after yellow flags have been displayed.
When a green flag is shown at a marshal post, it indicates that riders have passed the affected hazard area and normal track conditions have resumed in that section.
A green flag can also be used during the opening lap of certain sessions, sighting laps and warm-up laps according to the applicable procedures.
At the pit-lane exit, a green flag can indicate that the pit lane is open.
Why MotoGP Riders Must Know the Flags
MotoGP riders travel at extremely high speeds, often with only fractions of a second available to react to changing conditions.
Flags allow marshals and Race Direction to communicate important information without relying on radio communication with every rider.
A rider approaching a corner may need to know immediately whether:
- There has been a crash ahead.
- Overtaking is prohibited.
- The track is wet.
- Another rider is approaching.
- A motorcycle needs to be changed.
- The session has been stopped.
- The track is clear again.
- The race has finished.
Flags and Rider Safety
Flags are not simply warnings. They are part of the safety system used to manage a MotoGP event.
Riders must remain alert throughout every lap because conditions can change quickly. A section of track that was clear on the previous lap can suddenly contain debris, a crashed motorcycle, or a marshal attending an incident.
Ignoring a flag can create a dangerous situation for the rider, marshals and other competitors.
