In motorsports, a pit stop is where a racing vehicle stops in the pits during a race for refuelling, new tires, repairs, mechanical adjustments, a driver change, or any combination of the above. Not all are allowed in all formulae.
The pits usually comprise a pit lane which runs parallel to the start/finish straight and is connected at each end to the main track, and a row of garages (usually one per team) outside which the work is done. Pit stop work is carried out by anywhere from five to twenty mechanics (also called a pit crew), depending on the series regulations, while the driver waits in the vehicle (except where a driver change is involved).
Depending on the circuit, the garage may be located on pit lane or in a separate area. Most North American circuits feature a pit lane with number of pit stalls (typically 30-50) and a pit wall which separates the pit lane from the infield, with the garages (if used) on a separate road in the infield. In races where there are different series racing together, each series has its own separate garage or are parked in their own area. Circuits in other areas (used in F1) typically have the individual garage stalls open directly onto the pit lane through the team's assigned pit stall. In American English, it is common to drop the definite article and just refer to "pit road", whereas in British English one would always refer to "the pit lane". A further difference is that in British English, the term "pit box" is universally used, whereas in American English one would say "pit stall". It is important to note that in NASCAR, a pit box is a tool (see below).
For all but the shortest races, refueling is the primary purpose of a pit stop. Race engines generate high power but also burn fuel at an extreme rate, and most series have a limit on the size of the car's fuel tank, so many races will require multiple stops for fuel based on the distance of the race alone. However, many other adjustments can be performed during a pit stop, and some can even be performed without taking any more time than refueling. By making pit stops, cars can carry less fuel, and therefore be lighter and faster. During refueling, the tires can be changed as well, which permits the use of softer tires that wear faster but provide more grip. Teams usually plan for each of their cars to pit following a planned schedule, with the number of stops determined by the fuel capacity of the car, tire lifespan, and tradeoff of time lost in the pits versus how much time may be gained on the race track through the benefits of pit stops. Choosing the optimum pit strategy of how many stops to make and when to make them is crucial in having a successful race. It is also important for teams to take competitors' strategies into account when planning pit stops, to avoid being "held up" behind other cars. An unscheduled or extended stop, such as for a repair, can be very costly for a driver's chance of success, because while the car is stopped for service, cars remaining on the track can rapidly gain distance on the stopped car.
In most series (except NASCAR), pit assignments may be assigned by points standings, race results, or previous qualifying results before the start of the race meet. In NASCAR and in INDYCAR's Indianapolis 500, typically pit assignments are made after qualifying, with the fastest qualifiers choosing their pit stall first.
In any racing series that permits scheduled pit stops, pit strategy becomes one of the most important features of the race; this is because a race car travelling at 100 miles per hour (160 kilometres per hour) will travel approximately 150 feet (45 metres) per second. During a ten-second pit stop, a car's competitors will gain approximately one-quarter mile (one-half kilometre) over the stopped car.
However, the car that made the additional pit stop will run faster on the race track than cars that did not make the stop, both because it can carry a smaller amount (and thus lower weight) of fuel, and will also have less wear on its tires, providing more traction and allowing higher speeds in the corners. In racing series where teams have their choice of different compound tires, the lower tire wear may be enough to allow the team to choose to use a tire with a softer rubber compound that provides increased grip at the expense of faster wear; going longer between stops may even cause enough wear on the softer tire to cause the tires to fail.
Because of this, race teams plan a pit strategy prior to the start of every race. This is a schedule for each car's planned pit stops during the race, and takes into account factors such as rate of fuel consumption, weight of fuel, cornering speed with each available tire compound, rate of tire wear, the effect of tire wear on cornering speed, the length of pit road and the track's pit road speed limit, and even expected changes in weather and lighting conditions. The pit strategy does not just include a schedule of when pit stops will happen; it also includes what service and adjustments are scheduled for each pit stop, particularly in endurance racing, where scheduled changes of wear-limited parts such as brake pads may be planned for specific points during the race. The pit strategy is calculated carefully so that the amount of time to be "given away" to other competitors in pit stops is balanced out by the time gained while on the track, resulting, theoretically, in the shortest possible time to cover the scheduled distance.
However, a team's pit strategy is not a fixed, immutable thing; it is subject to change during the race to take into account the unpredictable events that happen in every race. In road racing, for example, if the weather changes from dry to rain, teams will be forced to recalculate their pit strategy based on the unscheduled stop to change from dry-weather "slick" tires to treaded wet-weather tires. Full-course caution periods often see mass pit stops by many teams, hoping to take advantage of the slowed pace to reduce the ground lost to other teams while making pit stops; this forces teams that do so to immediately recalculate their pit strategy to optimize it for the remaining race distance after the stop.
Even when a team chooses not to take advantage of the opportunity to stop during a full-course caution, it can still result in significant changes to pit strategy; under caution, the cars run at a reduced speed that results in greatly reduced tire wear and fuel burn for a distance travelled. Depending on the circumstances, this may be enough for a team to gain more by choosing not to pit, hoping that the reduced fuel burn and tire wear will allow them to make one pit stop fewer than the other teams, allowing them to gain distance and time on their opponents. At tracks noted for frequent full-course cautions, teams may even plan their entire race strategy around this, using a suspension and aerodynamic setup suited to short sprints instead of extended runs to gain positions in the short bursts of green-flag racing, and planning their pit strategy on the assumption that cautions will extend their fuel mileage and tire wear enough to make fewer stops than would otherwise be needed to complete the race distance.
During a scheduled pit stop, the team's pit crew services the car as swiftly as possible, completing a number of different services. The most visible services performed are refuelling the car and changing tires.
Other services performed in routine pit stops include removing debris from radiator air intakes; cleaning the windshield; and making adjustments to tire pressure, suspension settings, and aerodynamic devices to optimize the car's performance for the current conditions. In endurance racing, scheduled driver changes and brake pad replacements are also considered "routine" service when done as part of a scheduled pit stop.
An unscheduled pit stop may see other service performed; because unscheduled stops are usually due to damage or mechanical problems, they frequently see emergency repairs performed on the car. These tend to have extremely long duration, due to the need to diagnose the car's problems prior to the time-consuming repairs.
In Formula One, mid-race refuelling has been banned since 2010, and cars make pit stops with the primary purpose of changing tyres. Teams sometimes also make adjustments to the front and rear wings and perform minor repairs, most commonly replacing the nose and front wing assembly. Pit strategies generally call for between two and four scheduled stops, depending on the circuit. The drives between pit stops are commonly known as 'stints'.
When the car is approximately one lap away from making its stop, the team's pit crew will set up fresh tires and all needed pit equipment. Because of the overhead pneumatic rig, the team may have all pit mechanics in position prior to the car's arrival, with the exception of the rear jack man.
Interestingly, unlike almost all other forms of racing that feature routine pit stops, Formula One rules limit teams to a single pit crew for the mandatory two cars entered. Therefore, teams must stagger their pit schedules so that only one of their two cars is in the pits at any given time. Most other racing series that feature routine pit stops permit each car its own pit stall and crew.
Refuelling was permitted from the 1994 season until the end of the 2009 season. During this period, a pit stop involved about twenty mechanics, with the aim of completing the stop as quickly as possible. Stops generally lasted for six to twelve seconds depending on how much fuel is put into the car. However, if there is a problem, such as a fuel pump failing or the engine stalling, or repairs having to be made, it can take much longer. Cars were fuelled at a rate of more than 12 litres per second. This is accomplished by a fairly complex closed system that pumps air out of the car's fuel tank as the fuel is being pumped in.
As refuelling is a potentially hazardous situation, the mechanics wore fire-resistant multi-layer suits & flame-resistant gloves, long underwear, balaclava, socks and shoes, which have to meet the guidelines set by FIA Standard 8856-2000.
F1 pit crew roles
- The lollipop man holds the team's pit sign, helping the driver identify his pit stall on a possibly crowded pit road. During the stop, he holds the sign in position to remind the driver to keep his brakes on while tires are being changed, and then to remember to put the car in first gear once the jacks are lowered. He also gives the driver the sign to depart his pit stall by raising the sign from in front of the driver.
- In 2008, Ferrari used a traffic light system to replace the lollipop man. A red light signalled the driver to keep his brakes on, an amber light to put the car in first gear, and a green light to signal the driver to depart his pit stall. After human error caused Felipe Massa to drive off with his fuel hose still attached during the Singapore Grand Prix, Ferrari reverted to the Lollipop Man system. However, in the 2010 and 2011 seasons, Ferrari reverted to a traffic light system, as did some other teams.
- The four tyre changers, one at each corner of the car, have the sole responsibility of using a pneumatic wrench to remove the car's single locking lug nut from each tyre, then reinstall it on the new tyre.
- Eight tyre carriers are used, two at each corner of the car, one assigned the task of removing the old tyre from the car, and one to install the new tyre on it. The front new tyre carriers also have the responsibility of adjusting the car's front wing during the stop.
- The front and rear jack men use simple lever-type jacks to lift the car and permit the changing of tyres. The job of front jack man is considered the most hazardous, as it requires standing directly in front of the car as it enters its pit stall. By contrast, due to the location of his duties directly behind the car, the rear jack man is the only team member not in his working position before the car enters its pit stall.
- The fire extinguisher man does not actually work on the car; instead, he stands ready with a hand-held fire extinguisher to try to stop any accidental fires that may occur during a stop, at least long enough for the pit crew and driver to evacuate. This job became standard following Jos Verstappen's 1994 pit fire.
- The starter man does not normally work on the car. His job is to stand ready with a starter tool to restart the car should the driver stall his engine during the stop.
NASCAR Sprint Cup Series
Crew chiefs lead the pit crew during pit stops in addition to coaching the driver during the race. Pit crew members were once the mechanics on the racecar, but most teams feature individuals dedicated to pit stops only, and often former collegiate or professional athletes are used for pit stops. Former NFL player Tim Goad is regarded as the first former professional athlete involved in a pit crew, as a jackman. Nonetheless, some pit crew members work with the team in fabricating or designing the race cars during the week while training for their "pit job" on the weekends. Teams have built training centers similar to that of professional athletes for their pit crews.
There are a number of penalties that can be incurred on a pit stop. The driver must keep the car below the pit road speed from the pit entrance to the pit exit; the speed limit is typically 35-55 mph depending on the size of the track. Teams can be penalized if the car is serviced outside of the designated pit stall, if the car drives over an air hose, or if any of the old tires are not on the pit wall side (usually left) of the vehicle's centerline before the car leaves. The most common penalty for a pit infraction is a "drive-through": the driver must enter the pits again, under the green flag, and maintain the pit speed limit for the entire length of pit road. If a car stalls, the pit crew may provide a push start, but the car cannot be pushed beyond three pit stalls ahead of its own, or beyond the pit exit light and steward at the end of pit road.
Pit stops are timed from the moment the car stops in its pit stall, until service is finished and the car leaves the stall. A pit stop for four tires and fuel can last 12–16 seconds, and a stop for two tires and fuel may take 5–7 seconds. Late in a race, a team may only need a small amount of fuel to make it to finish; this is called a "splash and go" and may take as little as 2–3 seconds. These times depend upon any suspension adjustments performed and the quality of the crew.
NASCAR Sprint Cup Series team pit strategies vary widely, depending on the track. Fuel is generally a more limiting factor than tire wear, and the phrase "fuel window" or "pit window" is used to indicate the maximum number of laps possible with a full load of fuel, assuming continuous green flag conditions and a small reserve. The window is used to calculate (or recalculate after a stop) the minimum number of pit stops required to complete the race. The road courses on the schedule may see as few as two scheduled stops; oval race tracks generally see between four and six scheduled stops. Races at short tracks such as Bristol Motor Speedway and Martinsville Speedway are short enough to be completed with only two scheduled stops for fuel, but teams plan on more stops due to rapid tire wear and significant loss of cornering speed on worn tires.
Pit strategy can play a significant role in the outcome of a NASCAR race, perhaps more so than other racing series. Under caution, most teams use similar strategies to avoid being caught alone, typically following the leaders decision to stay out or pit, but sometimes teams will deliberately pit "off-sequence" if they feel they can gain an advantage later. Race tactics can affect strategy as well. Late in a race, drivers can reduce throttle input to save fuel at the cost of slower lap times, but by doing so they can stretch their pit window to the end of the race and skip the final pit stop. A late caution can force teams to make a tough call: stay out on worn tires, or pit and give up track position. The green-white-checker rule can cause headaches, as it can potentially extend the race an unknown number of both green-flag and yellow-flag laps. Furthermore, strategy can be determined by qualifying position. A team that qualifies in the top six positions will have the best choice of pit stalls, most often choosing the first, last, or a stall with an opening either in front of or behind that one. A team that qualifies deeper in the field will have a greater opportunity to be stacked behind cars during a pit stop, slowing them down.
NASCAR pit crew roles
- The Crew chief is the leader of the pit crew and assigns a Pit Crew Coach to help coordinate the pit stops and train the pit crew members how to stay in good physical shape. NASCAR regulations dictate that only six individuals can go "over the wall" to service a racecar during a pit stop. The tool limits on the crew are two impact wrenches, one jack, and two cans of gasoline. Other tools may be used if needed, but major work must be performed in the garage area. An important tool used by the crew chief is referred to as the pit box. The pit box is generally equipped with two satellites, along with several flat-screen monitors. These tools are used to help analyze the car up close during any moment of the race.
- The Car chief performs a majority of the scheduling and day-to-day preparations at the shop prior to the race weekend. This person is responsible for managing the crew throughout the weekend, ensuring that the car meets all of NASCAR’s inspection requirements, and overseeing changes to the car requested by the crew chief or the team engineer. This role is similar to that of a chief operating officer's in general.
- The jackman raises each side of the car so that the tires can be replaced. The jackman can do this quickly with the use of a 20-pound jack. The jackman will, also, usually pull the old right rear tire from the car after the rear tire changer loosens the lug nuts. This is to help get the new right rear tire on faster. The jackman signals for the driver to leave the pits by lowering the car.
- The two tire changers remove the lug nuts and (if not done by the jackman) the old tire, and tighten the new tire's lug nuts. One tire changer is responsible solely for the front tires, while the other is responsible for the rears. NASCAR requires a wheel to have five traditional lug nuts, as opposed to the single locking lug nut seen in Formula One. Many jackmen watch the tire changers to make sure the lug nuts are tight.
- The gas man fills the car with gasoline with a special gas can. The gas man may, also, help pull old tires from the race car after lug nuts are loosened if the car does not need fuel or if the car needs little fuel and the gas man finishes his job before anyone else.
- The two tire carriers bring new tires over the pit wall and guide them onto the studs. They must stay in contact with the old tires when they are being taken to the wall. The front tire carrier is usually responsible for pulling the front fenders away from the tire if necessary. He may also be responsible for cleaning and adding or removing tape to/from the grille during a pit stop in order to adjust front-end downforce and engine temperatures. The rear tire carrier is usually responsible for making any necessary adjustments to the rear track bar and/or wedge.
- The seventh man or utility is only permitted over the wall in the second half of the race (sometimes earlier if conditions and NASCAR dictate otherwise). He may clean the windshield and provide the driver with fresh drinking water and other necessities, but he may not make any other adjustments to the car.
In the IndyCar Series, a pit stop is a more complex operation than in NASCAR, but far less so than in Formula One. Rules permit six mechanics over the pit wall during a stop. The pit rules and procedures have origins in USAC National Championship racing.
During a routine pit stop, the tires are laid out and three of the four tire changers are pre-positioned before the car enters its pit stall; the fourth tire changer, whose responsibility is the rear tire on the far side of pit road from the pit wall, doesn't take his position until after the car arrives, due to a rule against having the car run over the feed hose for the impact wrench used to change the tires.
After the car arrives, the first step, taken while the fourth tire changer takes his position, is for a mechanic to insert the "vent hose" into its socket on the engine cowling. This hose vents the air out of the fuel tank, captures any overflow fuel, and also activates the car's built-in pneumatic jacks. After the vent hose is in place, another mechanic attaches the refuelling hose to its socket, allowing the ethanol fuel to flow into the fuel tank. Simultaneously, the four tire changers remove the tires and install the new ones. After the tire changes are complete, the front tire changers may use manual adjusters to adjust the angle of the car's front wing.
After the tire changes are complete, the vent hose is removed, allowing the car to return to its wheels. However, the driver usually must wait until the fuelling is finished and the fuel hose is removed from the car. The right front tire changer (who is usually also the crew chief) signals the driver when the stop is complete. Before the car departs its pit stall, a crew member must use a squirt of water to wash any excess fuel from the fuel hose and vent hose sockets; this is usually done with a pressurized hose by a crew member behind the pit wall.
Under normal conditions, a routine stop for an IndyCar team lasts between ten and fourteen seconds. IndyCar teams are permitted to set their own pit strategies.
In the various forms of sports car endurance racing, pit stops are a more leisurely affair, but no less important than in other forms of racing. While stops take longer, much more routine maintenance is scheduled during such pit stops, needed to keep the car running for as long as twenty-four hours; this includes major aerodynamic changes to deal with the changing temperature in such a long race, and replacement of certain wear-limited parts, such as brake pads. Due to the fact that the race is scheduled to last a certain length of time rather than a specific distance, pit strategies are generally not designed to be synchronized with the race distance, but rather to happen on a schedule based on the car's requirements for routine service.
Under the rules of the Automobile Club de l'Ouest (ACO) only five mechanics are permitted to work on the car. One man is permitted to fuel the car; all fuelling must be completed before any other service occurs. The other four mechanics on pit lane at any given time are typically two tire changers and two tire carriers, each of whom handles his task on only one side of the car. Automatic pneumatic jacks are used, integrated into the car itself. At all times the car's engine must be shut off during the stop, and may start only when the stop has concluded.
The Grand American Road Racing Association allows only four mechanics to service a car during a pit stop. One crew member will refuel the car while the other three are responsible for changing tires and operating the pneumatic jacks. A fifth crewmember must serve as the teams designated firefighter and must stand ready in the pit stall with a fire extinguisher while the car is being refuelled. A sixth crewmember may assist in a driver change. Neither the firefighter or driver's assistant may perform any additional service to the car itself. Unlike the ACO, Grand-Am does not force crews to wait for fuelling to complete before changing tires, and does not require the car's engine be shut off during the stop.
In endurance racing, driver changes are mandatory; the shortest endurance races are scheduled for four hours, one hour longer than the longest nonstop time permitted behind the wheel. During a pit stop with a driver change, the new driver and a driver change assistant are permitted into the pit lane. The assistant, who may not do any mechanical work on the car, is tasked with helping the current driver out of the car, removing or swapping driver seat inserts, helping the new driver into the car, and helping the new driver tightly fasten his safety harness and connect his various helmet connections to the car's systems, including the two-way team radio and the drink bottle used to stave off dehydration.
A routine pit stop with no scheduled maintenance and no driver change generally lasts from thirty to forty seconds. With a driver change included, that time increases by about ten seconds. Should there be significant scheduled maintenance, such as changing brake pads, the stop can easily last well more than a minute.
Unlike most other forms of racing, the practice of "double-stinting" or even "triple-stinting" tires is commonplace in longer races; tires hard enough to withstand the rigours of racing in the heat of the daytime may be so hard that they do not wear significantly during the nighttime hours. In a race where this is an issue, significant time can be gained by choosing to leave worn tires on the car during the first stop after they were put on the car; if the temperature drops low enough, teams may even be able to go two pit stops without changing tires.
The frequency of pit stops depends on a large number of factors, such as fuel consumption, fuel tank size, and tire wear. In endurance events such as Super GT, the pitstops and driver changes during the race are done within mandatory windows, which is similar to the two stops that are obligatory under the rules of Deutsche Tourenwagen Masters. Since the 2007 Formula One season, two different tyre compounds must be used during a race, effectively setting the minimum number of pitstops to one.

Notable pit stops
- 1963 Daytona 500: Wood Brothers Racing developed choreographed pit stops to reduce the amount of time spent on pit road. Driver Tiny Lund spent so little time on pit road that he went on to win the race without changing his tires once. For this, Wood Brothers Racing is often credited with inventing the modern pit stop.
- 1965 Indianapolis 500: Wood Brothers Racing fielded a Ford powered Lotus driven by Scottish Formula One driver Jim Clark. This brought their new concept of fast pit stops into open-wheel racing. Clark won the race with an average speed of 150.686 (a new Indianapolis 500 record). This was Ford's first win at Indy.
- 1976 Indianapolis 500: A world record was set for time taken in a pit-stop when Bobby Unser pitted in four seconds.
- 1981 Daytona 500: During the final round of pit stops, Richard Petty's crew called off a planned tire change, and serviced fuel only. The lightning-fast stop put Petty back on the track in the lead, and he held off a shocked Bobby Allison for a record 7th Daytona 500 victory.
- 1982 Indianapolis 500: Gordon Johncock and Rick Mears were running together on the track as they approached their final pit stops. Johncock's crew saved time by giving him just enough fuel to finish the race, sending him out with an 11-second lead. The better-handling Mears closed the gap but ran out of laps as Johncock hung on to win by 0.16 seconds.
- 1989 Portuguese Grand Prix: Nigel Mansell came in too fast and missed his pit box. He then reversed back to take his spot, and mechanics changed the tyres. Due to reversing in pit lane, he was disqualified. He did not acknowledge the black flag, collided with Ayrton Senna and was given one-race ban.
- 1991 First Union 400: After an offseason of discussion at the end of the NASCAR season during the Atlanta Journal 500 when Melling Racing rear tire changer Mike Rich was killed by Ricky Rudd's car going out of control during a pit stop, NASCAR experimented with various rules on tire changes in an attempt to prevent a similar incident from happening again. The first was to only allow tire changes during green flag racing, with the first lap after the restart being assigned to cars that started in odd-numbered starting positions, and the second lap after restart for even-numbered starting positions. The rule was unpopular, and teams began to change tires only for regularly scheduled times under the green flag. After the first five races, NASCAR experimented with a rule for the Valleydale Meats 500 in Bristol. The same odd-even rules were used for the first two laps of a pit stop under caution, with the cars starting double-file, with the odd cars on the inside and even cars on the outside. After more complaints, for the seventh race, at North Wilkesboro Speedway, NASCAR reverted to the rules prior to the 1990 crash, along with a new rule mandating a pit lane speed limit. By the middle of the 1990s, almost all motorsport began enforcing a pit lane speed limit.
- 1991 Toyota Grand Prix of Long Beach: Michael Andretti's pit service was complete as he passed by Emerson Fittipaldi, who began exiting his pit area. Fittipaldi was apparently unaware that Andretti was approaching, and as the two made wheel-to wheel contact Andretti's car was launched into the air. Andretti's damaged car slid into another pit stall, but, though very angry, Michael walked away uninjured. As this incident took place in the wake of a tragic crash in NASCAR that killed a mechanic, this incident prompted CART to mandate pit lane speed limits.
- 1991 Portuguese Grand Prix: Nigel Mansell lost a wheel instantly after making his stop. The mechanics put the wheel back on in the middle of pit road, and Mansell was disqualified for the second time in three years in the event.
- 1993 Australian Grand Prix: McLaren's Ayrton Senna came into the pit unexpectedly for new tires; the team serviced the car in under four seconds.
- 1994 San Marino Grand Prix: Michele Alboreto lost a wheel after his pit stop. The wheel caused injuries to mechanics from Ferrari and Lotus. Following this and other tragic events during the weekend, the pit lane speed limit was introduced in Formula One.
- 1994 German Grand Prix: Benetton driver Jos Verstappen came into the pits; while refuelling, some fuel was accidentally sprayed onto the hot bodywork of the car – a few seconds later the fuel ignited and Verstappen's car was engulfed in a ball of flames. Verstappen escaped the incident with burns around his eyes, as he had his visor up during the pit stop.
- 1995 Spanish Grand Prix: Johnny Herbert exited his pit box with the rear jack still attached to his car. It fell off harmlessly at the pit lane exit.
- 1996 24 Hours of Daytona: "Mad Max" Papis was charging around the track on the final stint of the race, trying to catch the leader. On his final pit stop, Papis entered the pit area at full speed (~200 mph). Despite still finishing second, the startling sight helped earn him the name "Mad Max." This is no longer possible, as almost all federations controlling motorsport have adopted pit lane speed limits because of crew safety.
- 1998 British Grand Prix: Two laps from the finish, Ferrari driver Michael Schumacher was issued with a ten-second penalty, meaning he had to drive through the pit lane obeying the speed limit, stop at the penalty box (not the team's pit box), and remain stationary for ten seconds before leaving the pits and continuing with the race. On the final lap of the race, Schumacher came in to serve the penalty and in doing so crossed the finish line (which extends across the pit lane) before reaching his pit box and before Mika Häkkinen crossed the finish line on the race track.
- 1999 Portland Grand Prix: Gil de Ferran was leading but had insufficient fuel to make it to the finish. Rather than try to conserve fuel, de Ferran's Walker Racing team instructed him to drive all-out to build enough of a margin to make an extra pit stop. The strategy was a gamble as a yellow flag would bunch the field and wipe out any margin de Ferran built. The green flag stayed out, de Ferran pitted without losing the lead and he went on to take the team's first win in four years.
- 2001 24 Hours of Le Mans: Joest Racing changed the transaxle on their Audi R8 (a process that usually takes hours) in less than 5 minutes. They went on to win the overall race.
- 2002 UAW-Daimler Chrysler 400: Sterling Marlin of Chip Ganassi Racing spun while attempting to make a late race pit stop, causing him to break the pit road speed limit. At the time, NASCAR's penalty for speeding while entering pit road was to hold the driver in his pit stall for an additional 15 seconds. The official in Marlin's pit was not informed of the penalty until after the crew released the car. NASCAR determined that they had no precedent for forcing Marlin to return to the pits as his early release was their mistake (and they could not order him back for a stop and go penalty). Marlin won the race by 1.163 seconds. Following the incident, NASCAR amended its rules so that all speeding violations are enforced with a drive through penalty (forcing the driver to travel the length of pit road at the speed limit).
- Sprint All-Star Race XVIII (2002): Roush Racing's Jeff Burton made a pit stop on the final lap of the first 40-lap segment. A pit stop for tires was mandatory during the segment, but the rule did not stipulate when it had to be taken. By selecting a pit stall only 100 yards shy of the start/finish line, Burton did not have to spend the time all the other drivers took traveling the entire length of pit road. Since Sprint All-Star Race XIX, the rule was modified to mandate the stop within a specific number of laps in the race.
- 2008 Canadian Grand Prix: Ferrari's Kimi Räikkönen came to a stop at the end of the pit lane as the exit was closed, with the red indicator light on. Räikkönen was alongside BMW's Kubica at the end of the pit lane when Hamilton sped towards them not noticing the red light at first. Hamilton slid into the back of Räikkönen's car, with Nico Rosberg further hitting the back of Hamilton. Both Hamilton and Räikkönen retired from the race, each leaving their vehicles at the exit of the pitlane. Both Hamilton and Rosberg were penalised a 10 place grid penalty at the next Grand Prix in France.
