Formula One regulations

The Formula One regulations, made and enforced by the FIA, are rules that govern car specifications, racing procedures, scoring, and penalties in Formula One. The primary goals of the Formula One regulations are to ensure driver safety and fairness in competition. As of 2026, the regulations are designed with an additional goal of promoting environmental sustainability in the sport.

There are two main types of regulations; technical and sporting. Technical regulations are related to car specifications, such as the chassis or the engine. Meanwhile, sporting regulations involve race procedures and set rules that pertain to the sport as a whole. There are also financial regulations that place restrictions on the budgets of teams and power unit manufacturers, and operational regulations that dictate factory testing procedures.

The regulations in Formula One are updated by the FIA on a yearly basis. Typically, only minor changes are made, such as in order to close loopholes, improve safety, or adjust the scoring system. However, major regulation changes have also occurred, such as in 2014, with the introduction of 1.6-litre V6 turbo-hybrid engines, and in 2026, with the significantly increased electrification of the engine and the introduction of new power unit and aerodynamic modes. Such major regulation changes are announced years in advance, to give teams and manufacturers time to plan and design the new cars.

Current rules and regulations

Technical

Chassis

An F1 car can be no more than 190 cm wide and 95 cm tall. Though there is no maximum length, other rules set indirect limits on these dimensions, and nearly every aspect of the car carries size regulations; consequently the various cars tend to be very close to the same size. The car and driver must together weigh at least 724 kg as of 2026. The same chassis must then sustain a rear impact from a sled travelling at , with no damage in front of the rear axle. Side impacts by a object at must be decelerated at less than 20g, and absorb no less than 15% and no more than 35% of the total energy; can not be exceeded more than 3 milliseconds. Active suspensions were also banned in 1994 due to safety concerns by the FIA over ever-higher speeds, and other "driver aids" were also banned that same year, including 4-wheel steering, which was tested and found to provide negligible if any reduction in lap times.

Since 2014, transmissions with 8 gear ratios and 1 reverse gear ratio are required in Formula 1 cars.

The engines, now commonly referred to as power units, are divided into 6 components: the internal combustion engine (ICE); turbocharger (TC); Motor Generator Unit-Kinetic (MGU-K), which harvests energy that would normally be wasted under braking; Energy Store (ES), which functions as a battery, storing the energy gathered by the MGU-K; Control Electronics (CE), which includes the Electronic Control Unit and software used to manage the entire power unit; and Exhaust (EX). From 2014 to 2025, there was a seventh component called the MGU-H (Motor Generator Unit-Heat), which collected energy in the form of heat as it was expelled through the exhaust, but it was removed from the 2026 regulations due to being overly costly and complex for new teams to develop.

In 2026, each driver may use up to four ICEs, Turbochargers, and Exhaust sets, and up to three MGU-Ks, Energy Stores, and Control Electronics throughout the season; however, from 2027 onward, this allocation will decrease to only three and two respectively, unless it is the manufacturer's first year supplying power units since the onset of the 2026 regulations. A grid place penalty will be enforced upon drivers who exceed these allocation limits, once for each additional component at the first event where the replacement element is used.

Devices designed to inject any substance into the cylinders other than air and fuel (petrol) are forbidden, as are variable-length intake and exhaust systems. The crankshaft and camshafts must be made from an iron-based alloy. The use of carbon composite materials for the cylinder block, cylinder head and pistons is not allowed. Separate starting devices may be used to start engines in the pits and on the grid. If the engine is fitted with an anti-stall device, this must be set to cut the engine within ten seconds in the event of an accident.

From to , 2 types of dry tyres were provided at each race weekend, known as the Prime and the Option. Teams are supplied with more sets of Prime tyres than Option tyres for use throughout the weekend. The Prime tyre is usually harder and therefore more durable than the Option tyre, while the Option tyre provides more grip and therefore allows faster lap times when the tyres are fresh. At some events the selection is reversed, with the Option tyre being harder than the Prime. The combination of longer lasting and faster tyres adds an element to each car's race strategy. Additionally, 2 wet-weather compounds are provided by the supplier: intermediate and full wet.

From onward, 3 dry tyre compounds are brought to a race weekend. Since 2019, regardless of tyre compound, one tyre is designated as soft, one as medium, and one as hard. One set of the softest tyres is set aside for Q3 and two sets of the middle and the hardest tyres are kept for the race. Each compound is differentiated by a colour-coded band painted around the tyre's sidewall including the supplier's logo: red for soft, yellow for medium, white for hard, green for intermediate, and blue for full wet.

Competitors are allowed only a limited number of tyre sets during a race weekend: 13 dry, 4 intermediate, 3 wet. However, if the race weekend includes a sprint race, only 12 sets of dry tyres are allocated. Each tyre must be marked with a unique identifier for tracking and scrutinising during a race event. During the practice sessions drivers are limited to the use of 3 sets of dry tyres, and certain sets must be returned to the supplier before the second and third sessions. From 2014 to 2021, if qualifying and starting the race on dry tyres, drivers who completed a lap during the third period of qualifying (the top ten) were required to start the race on the tyre set with which they recorded their fastest time during the second period. Any cars that qualified outside the top ten may have started the race on any remaining set of tyres. This rule was removed prior to the 2022 season. Cars must race on any 2 dry compounds during a race unless intermediate or wet tyres have been used by that car in that race.

Prior to qualifying, wet and intermediate tyres may only be used if the track is judged wet by the race director. Starting the race behind the safety car due to heavy rain requires cars to be fitted with wet tyres until they make a pit stop.

Heaters may be applied only to the outside of tyres.

Aerodynamics

Historically, constructors were able to build Formula One cars around the concept of ground effect. Following the deaths of Roland Ratzenberger and Ayrton Senna in the season, skid blocks were mandated to increase the ride height, reduce the impact of ground effect, and slow the cars down. However, from 2022 to 2025, ground effect was re-introduced to the Formula One regulations. The 2026 regulations have once again reduced the impact of ground effect, with flatter floors and an increased ride height.

From to , the drag reduction system, which was a piece of movable aerodynamics on the car's rear wing, was mandated. In 2026, it was replaced by a system called Active Aerodynamics in which both the car's front and rear wings may rotate between two positions. In their upright closed position, called 'corner mode', they increase downforce on the car in order to improve tyre grip, allowing the car to make turns at higher speeds. Their flat open position, called 'straight-line mode' or more simply 'straight mode', trades reduced downforce and grip for a reduction in drag, allowing the car to achieve a faster top speed in a straight line.

Sporting

Parc fermé

After weighing during each qualifying session, teams are required to take their cars to a place in the paddock, sectioned off by the FIA, known as parc fermé; they may not do work on the cars, other than routine maintenance, until they are released from parc fermé for the race the next morning.

If a team must do other significant work, body work or suspension adjustments, including switching to another chassis or setup, the car will start from the pit lane.

The pit lane opens forty minutes before the start of a race (t−40:00). Drivers may do as many reconnaissance laps as they wish, driving through the pit lane each time around in order to avoid the grid. Drivers must be in their cars and in place on the grid by time the pit lane closes at t−30:00; otherwise they must start the race from the pits. Meanwhile, teams may work on their cars on the grid.

At t−10:00 the grid is cleared of everyone except team mechanics, race marshals, and drivers. A team will generally want to keep its tyres off their cars and heated in their tyre-warmers for as long as possible, but they must be attached to the cars by t−3:00.

Engines must be running by t−1:00; at fifteen seconds to the start all personnel must be clear of the track. Green lights signify the start of the formation lap, also known as the parade lap, during which drivers must remain in the same order (no passing) except if a car ahead has stopped due to a technical problem, or has had an accident. The cars circle the track once, usually weaving from side to side to warm up their tyres, and form up again in their starting positions on the grid. A series of short, controlled burnouts is usually performed as each driver approaches their grid box in order to maximize rear tyre temperature and clean off any debris from the parade lap.

If, for some reason, a car cannot start the race (engine failure during qualifying or practice, suspension fails, etc.), the car can still join the race, but will take a 10-position penalty at the start. For example, if the car qualifies in 3rd, but has to change an engine at any point during the race weekend prior to the actual race, the car will start from 13th position. For strategy's sake, teams will sometimes opt to start a car affected in this way from the pit lane. This means they start at the tail end of the grid; however, they can not only change an engine, but also start the race with fresh tyres.

Gearboxes must be used for five consecutive events (counted as P3, the qualifying practice session and the race). A 5-place grid penalty will be incurred if a replacement gearbox is used (Pole position becomes 6th). Due to the reliability of modern gearboxes, in 2025 the grid penalties incurred for replacement gearboxes was removed.

The race is started by ten red lights in two rows of five (i.e. 5 columns of 2). The red lights in each column operate as a pair i.e. both go on and off together. The lights illuminate one pair at a time, left to right, in one-second intervals, and then go out simultaneously after a random interval (i.e. 4–7 seconds). When the lights go out, the race officially begins. Should the start need to be aborted for any reason, all 5 pairs of red lights will come on as normal, but instead of going out, the orange lights will flash. All engines are stopped and the start resumes from the 5-minute point. If a single driver raises their hand to indicate that they can't start, the marshal for that row will wave a yellow flag, then after a few seconds, both the red and orange lights will extinguish and the green lights will come on to indicate another formation lap.(No overtaking in formation laps)

Scoring

The Drivers' and Constructors' Championships are decided by points, which are awarded according to the place in which a driver classifies at each Grand Prix. To receive points a racer need not finish the race, but at least 90% of the winner's race distance must be completed. Therefore, it is possible for a driver to receive some points even though they retired before the end of the race. In that case the scoring is based on the distance completed in comparison to other drivers. It is also possible for the lower points not to be awarded (as at the 2005 United States Grand Prix) because insufficient drivers completed 90% of the winner's distance. The system was revised in 2003 and later amended for the 2010 season because of two new teams entering the sport. From 2019 to 2024, a point was awarded for fastest lap, but this was discontinued for 2025. The scoring system from 2025 on is:

{| class="wikitable"

|+ Driver completed 90% of winner's race distance

| 1st place || 25 points

| 2nd place || 18 points

| 3rd place || 15 points

| 4th place || 12 points

| 5th place || 10 points

| 6th place || 8 points

| 7th place || 6 points

| 8th place || 4 points

| 9th place || 2 points

| 10th place || 1 point

| 11th place onwards || No points

For scoring systems prior to 2025, refer to the List of Formula One World Championship points scoring systems. Drivers finishing lower than tenth place receive no points.

From 2010 until the end of 2021 championship, if the race had to be abandoned for any reason before 75% of the planned distance (but after a minimum of two completed laps), then the points awarded were halved: 12.5, 9, 7.5, 6, 5, 4, 3, 2, 1, 0.5. The rules regarding the awarding of points were reviewed by FIA, teams and Formula One following criticism after the 2021 Belgian Grand Prix, during which the race was red flagged on lap 3 after two laps behind the safety car, with no laps having been completed under green flag conditions at racing speed, before the race was abandoned prematurely, with the race result—a win for Max Verstappen—being taken after the first lap. More than two laps were considered by the FIA to have been completed by the leader because the leader Verstappen had crossed the control line three times before the race was abandoned.

Following this, the point allocation for suspended races was changed for the 2022 season. The points awarded follow a gradual scale system as follows:

No points will be awarded unless a minimum of two laps had been completed under green flag conditions.
If more than two laps are completed, but less than 25% of the scheduled race distance, points will be awarded to the top 5 on a 6–4–3–2–1 basis.
If 25%–50% of the scheduled race distance is completed, points will be awarded on a 13–10–8–6–5–4–3–2–1 basis to the top 9.
If 50%–75% of the scheduled race distance is completed, points will be awarded on a 19–14–12–9–8–6–5–3–2–1 to the top 10.

If more than 75% of the scheduled race distance is completed, full points will be awarded.

However, these rules do not apply and full points will be awarded when a race is suspended and then resumed, even if the whole race distance cannot be completed in the 3 hour race window. However, this was changed for 2023 thereby satisfying the original intent of the gradual scale system.

Points are awarded equally to the driver and their constructor; for example, if a driver for one team comes second, eighteen points are added to their season total; if their teammate finished third in the same race, they add fifteen to their total and the team adds 33 (the sum of the drivers' points) to its total. The championships are awarded to whichever driver and constructor have the most points at the end of the season. In case of a tie, the FIA compares the number of times each driver has finished in each position. The championship goes to whichever had the greater number of wins; if they have the same number of wins, it goes to the driver with the greater number of second places, and so on. For example, if drivers A and B were tied at the end of a season, and B had six wins and 3 second-place finishes, but A had six wins and four second-place finishes (even if they had fewer third places than B, etc.), then A would be champion.

On 10 December 2013, it was confirmed that drivers and constructors would score double points in the final Grand Prix from 2014 onwards, but this was abandoned in the weeks following the 2014 season.

Flags

Many venues make use of electronic displays to indicate flags to give various messages to drivers. However, race marshals continue to use physical flags as a redundancy mechanism in the event of electronic display failure. Marshals are positioned at numerous points around the track during every race. Flags have different meanings depending on their colour; the colours (with Pantone values as specified by the FIA) signify as follows:

{| class="wikitable" style="width:100%; margin:auto;"

|- "

! Flag !! Pantone value !! Description !! Meaning

| 70px

| Yellow

| Caution

A single yellow indicates danger ahead, such as debris from a crash. Drivers must slow down as they pass; overtaking is forbidden, unless it is unavoidable such as a driver retiring in the section, or a driver is lapped.
2 waved yellows at the same post indicates great danger ahead. Drivers must slow down and be prepared to stop; no overtaking is permitted unless a driver is lapped.

A drive-through penalty requires the driver to enter the pit lane, drive through it while obeying its speed limit, and exit without stopping. As a drive-through penalty does not require the driver to stop, it is less costly than a stop-go penalty.

A ten-second stop-go penalty requires the driver to enter the pit lane, stop at their pit for ten seconds, and exit again. As the stop is designed to punish the driver for an offence, team mechanics are forbidden to work on the offending car at any time while the driver is serving the penalty. Stop-go penalty is the harshest penalty short of disqualification and is given for serious offences such as endangering other drivers. This occurred at the 2024 Qatar Grand Prix, where Lando Norris was penalized for failing to slow down under double-waved yellow flags, caused by debris on the main straight, costing him around 35 seconds in race time.

For drive-through and stop-go penalties, a driver has 2 laps from the time their team hears of the penalty to enter the pits; if the driver does not pit within 2 laps, the driver will be black-flagged. The exception to this rule is if the Safety Car is deployed before a driver serves their penalty, in which case the driver is not allowed to serve the penalty until after the Safety Car comes back in. If the driver incurs a penalty within the last 5 laps of the race, the driver need not pit at all; instead, twenty seconds will be added to their total race time in case of a drive-through penalty, and thirty seconds in case of stop-go penalty.

The most severe penalty in common use is a black flag, which may be imposed for ignoring penalties or for technical irregularities of any sort; it signifies that the driver has been disqualified from the race and their results for that race will not count toward the championship. If the black flag is not considered sufficient for the offence that the driver has committed, the driver may be banned for a number of races after the event. For example, Romain Grosjean's crash at the 2012 Belgian Grand Prix earned him a one-race ban at the next race. In modern Formula One, most disqualifications have occurred due to infringements found during post-race scrutineering; for example, Sebastian Vettel was disqualified from the 2021 Hungarian Grand Prix due to insufficient fuel sample, and Lewis Hamilton and Charles Leclerc were both disqualified during the 2023 United States Grand Prix due to excessive plank wear.

A grid penalty may be given for the next race, which may increase depending on the severity of a penalty. Grid penalties have also been given due to exceeding the quota of an engine component, but from gearboxes are exempt. For example, a 5-place grid penalty means if the driver qualified first, they would start the race from sixth position.

Should a driver accumulate twelve unexpired penalty points at the same time, they will be banned from participating in the following race and would have to be replaced by another driver.

The most extreme punishment of all (used for seriously endangering the life of another driver or trying to gain an unfair advantage in the championship) is to be excluded from the drivers' world championship that year. Such cases may be taken to judicial court. The only time that this has happened was in 1997, where Michael Schumacher, at the final race, deliberately turned in on Jacques Villeneuve, damaging both cars and taking himself out of the race, though inflicting enough damage to Villeneuve's car to slow him down. Teams may also be excluded from the Constructors' Championship; some examples include the Tyrrell team in due to a technical infringement, and McLaren due to the "Spygate" scandal in .

Pit to car messages

There is no restriction on what information can be given to the driver, except during the formation lap.

Previously, to ensure that drivers drive the car 'alone and unaided' and are not being 'coached' from the pit wall, stricter rules were in place to govern what information could and could not be given to a driver over team radio. For example, it was not allowed for a driver to be given information about driving lines or how to adjust their car to make it faster whilst out on the track. These restrictions were removed at the 2016 German Grand Prix.

History

The primary reasons behind rule changes have traditionally been to ensure safety and, in more recent years, to limit the cost of the sport.

Regulation disputes

Formula One teams have often sought to exploit loopholes in the regulations in order to gain a competitive advantage. When they do so, other teams typically take notice and report them to the FIA for review. In such situations, the FIA may determine the team to have breached the regulations, and enact a financial or sporting penalty. Alternatively, the FIA may determine the loophole to be a fair and acceptable interpretation of the regulations, but still choose to close the loophole for the future.

Examples of notable Formula One regulation disputes include:

2009: Brawn BGP 001 double diffuser
2019: Ferrari Tipo 064 power unit fuel-flow
2026: Mercedes and Red Bull power unit compression ratio
