Rules and Regulations

Flag System

Flags are one of the primary ways that race control communicates with drivers during a session. Each flag color carries a specific meaning, and ignoring a flag can result in serious penalties. Modern Formula 1 circuits also use electronic light panels around the track that mirror the flag signals, making them easier for drivers to see at high speeds.

Green Flag

The green flag signals that the track is clear and racing can proceed at full speed. It is shown at the start of sessions and after an incident zone has been cleared. Drivers are free to overtake and push their cars to the limit when the green flag is displayed.

Yellow Flag (Single)

A single yellow flag warns drivers that there is danger ahead, such as a car off the track or debris on the circuit. Drivers must slow down and are not permitted to overtake in the yellow flag zone. Under the 2026 regulations, one method of demonstrating compliance is to increase the time taken to traverse the flag sector by at least 5% compared to the driver's previous lap under similar conditions.

Yellow Flag (Double)

A double waved yellow flag indicates a more serious incident where the track may be partially or fully blocked and marshals may be on or near the circuit. Drivers must slow down significantly and be prepared to stop if necessary. The required speed reduction must be noticeably greater than under a single yellow flag.

Red Flag

The red flag means all track activity is stopped immediately. It is used for serious accidents, dangerous weather conditions, or any situation where the track is unsafe. During a race, all drivers must slow down, return to the pit lane, and wait for further instructions from race control before the session can resume.

Blue Flag

The blue flag is shown to a driver who is about to be lapped by a faster car. Upon receiving a blue flag, the slower driver must allow the faster car to overtake at the earliest safe opportunity. If a driver ignores three consecutive blue flags without letting the faster car through, they will receive a penalty from the stewards.

Other Flags

• Yellow and Red Striped: This flag indicates that the track surface is slippery, which is often caused by oil, water, or debris on the circuit.
• White: The white flag warns drivers that a slow-moving vehicle, such as a recovery crane or medical car, is on or near the track.
• Black: The black flag means the driver has been disqualified from the session and must return to the pits immediately.
• Black and White: This flag serves as an official warning for unsportsmanlike behavior. If the driver commits another offense, they will receive a penalty.
• Black with Orange Circle: This flag tells the driver that their car has a mechanical problem that could be dangerous. The driver must return to the pits for repairs before continuing.
• Checkered: The checkered flag signals the end of a session or race. It is waved when the leader crosses the finish line.

Safety Car and Virtual Safety Car

Safety Car (SC)

When a serious incident occurs on the track, race control may deploy the physical Safety Car, which is a high-performance Mercedes-AMG driven by Bernd Mayländer, who has held the role since the year 2000. The Safety Car enters the circuit and all drivers must slow down and fall into a single-file line behind it at reduced speed. No overtaking is allowed while the Safety Car is on the track.

The purpose of the Safety Car is to allow marshals to safely clear debris, recover damaged cars, or repair barriers without putting anyone at risk. All laps completed under the Safety Car still count as race laps. Once the incident has been cleared, the Safety Car returns to the pit lane and racing resumes.

Virtual Safety Car (VSC)

The Virtual Safety Car was introduced in 2015 and is used for less severe incidents, such as a stranded car near a marshal post, where a full Safety Car deployment is not needed. There is no physical car on the track during a VSC period.

When the VSC is deployed, all drivers must reduce their speed by approximately 30% across every sector of the circuit. Each driver follows a delta time displayed on their steering wheel to ensure they are maintaining the correct reduced speed. Overtaking is not permitted during the VSC period. Once the incident has been cleared, the "VSC Ending" message is displayed on the timing screens, and after a short countdown the green signal is shown and racing resumes immediately.

Active Aero and Overtake Mode

For the 2026 season, the Drag Reduction System (DRS) that was used from 2011 through 2025 has been replaced by a more advanced system built around movable wing elements and electrical power management. Cars now feature fully movable front and rear wings that switch between two configurations throughout each lap.

Active Aerodynamics

All cars in 2026 operate in two aerodynamic modes as they travel around the circuit. In Corner Mode, the wing flaps on both the front and rear wings are closed to generate the maximum amount of downforce, which gives the car more grip through corners. In Straight Mode, the wing flaps on both the front and rear wings open simultaneously to reduce drag and increase top speed on designated straights around the circuit.

Unlike the old DRS system, Straight Mode is available to every driver on every lap in the designated activation zones. A driver does not need to be within one second of the car ahead to use it. In wet conditions, race control can enable a partial aero mode where only the front wing elements open while the rear wing stays in Corner Mode to maintain rear stability.

Overtake Mode

Overtake Mode is the direct replacement for DRS as the primary overtaking aid in Formula 1. When a driver is within one second of the car ahead at a designated detection point (typically at the final corner of the lap), they are granted an extra 0.5 MJ of electrical energy to deploy on the following lap. The lead car's electrical power tapers off above 290 km/h, while the overtaking car in Overtake Mode can use the full 350 kW of electrical power up to 337 km/h, which creates a meaningful speed difference on the straights.

The driver can choose to use this extra energy all at once for a single burst of speed or spread it across the entire lap for a more strategic approach. Overtake Mode becomes available one lap after the start or restart of a race and activates immediately after the Safety Car returns to the pits. The race director retains the authority to disable Overtake Mode if conditions require it.

Boost Mode

Boost Mode is activated by pressing a button on the steering wheel that triggers a change in the power unit's settings. The setting can either be a personalized profile configured by the team's engineers, or one that deploys extra battery power that has been harvested through the energy recovery system. Unlike Overtake Mode, Boost Mode does not require the driver to be close to another car and can be used both when attacking to attempt a pass and when defending to hold a position. Its effectiveness depends entirely on how much energy the driver has stored in the battery during the lap.

Track Limits

Drivers must keep at least part of their car in contact with the track at all times during a session. The white lines painted on the edges of the circuit are considered part of the track. If all four wheels of a car cross entirely beyond the white line, it is counted as a track limits violation. The stewards will always confirm that each infraction is clear before counting it, and drivers will be given the benefit of the doubt when the violation is not obvious.

Penalty Escalation

Track limits violations follow a "three strikes" system that escalates with each additional offense during a race or sprint session.

1. First and second violations: The infraction is noted by race control, but no penalty is issued.
2. Third violation: The driver is shown the black and white flag as an official final warning.
3. Fourth violation: The driver receives a 5-second time penalty.
4. Fifth violation: The driver receives a 10-second time penalty.
5. Further violations: The cycle of escalating penalties repeats for every additional infraction.

Pit Stop Rules

Pit stops are a mandatory part of every dry weather race in Formula 1. Because the regulations require drivers to use at least two different tire compounds during a Grand Prix, at least one pit stop is needed to change tires. In wet weather races where rain tires are used throughout, this requirement does not apply.

Key Pit Lane Rules

• Speed Limit: There is a strict speed limit of 80 km/h in the pit lane during race sessions at permanent circuits. If a driver exceeds the pit lane speed limit, their team may be fined on a sliding scale based on how far over the limit the driver was traveling.
• Pit Exit: A traffic light system at the end of the pit lane controls when cars can rejoin the track. Cars may only exit the pit lane when the light is green. A flashing blue light at the pit exit warns drivers leaving the pits if cars are approaching on the main track.
• No Reversing: A car may never be reversed under its own power in the pit lane at any time.
• Unsafe Release: If a team releases a car from the pit box into the path of another car or into oncoming traffic, the team may receive a fine or the driver may be given a time penalty.

Serving Penalties in the Pits

Time penalties of 5 or 10 seconds can be served during a scheduled pit stop. After the car comes to a stop in its pit box, the mechanics must wait the full penalty duration before they are allowed to touch the car and begin working on it. If any mechanic touches the car before the penalty time has elapsed, the driver will receive an additional penalty for serving it incorrectly.

Late-Race Penalties

If a drive-through or stop-and-go penalty is imposed during the last three laps of a race, the driver is not required to serve it in the pit lane. Instead, 20 seconds will be added to the driver's total race time for a drive-through penalty, or 30 seconds will be added for a stop-and-go penalty.
