The fixed green flag is usually displayed by the starter to indicate the start of a race. During a race, it is displayed at the end of a yellow time or temporary delay to indicate that the race is starting again. The waving of a green flag is almost universally complemented by the illumination of green lights (similar to traffic lights) at different distances around the course, especially on ovals. In MotoGP, a white flag is used to warn riders of rain. Stop! If you see a red flag on the track, you should stop immediately and leave the track. This means either that a driver is injured on the track and needs medical attention, or that track conditions do not allow the race to continue. When the safety car is on the track, a “Safety Car Board” is displayed on all points of the flag (a large whiteboard with “SC” in large black letters). If the flag points are radio controlled, this is done immediately, otherwise the table will be displayed when the safety car comes for the first time. This is accompanied by a waving yellow flag. The usual yellow flag conditions apply to the entire circuit; Remarkably, overtaking is totally prohibited. When the safety car arrives and the race continues, a green flag is displayed on the start line and then at all flag points around the track for one lap. Overtaking is only allowed when the cars have crossed the start/finish line, or in Formula 1 the safety car line at the pit entrance.
 The FCY procedure will be used at the 2019 24 Hours of Le Mans in response to Porsche`s dominant GTE-Pro victory in 2018. Partial lane slowdown zones are indicated by horizontal wayside markings at the beginning and end and by “Next Slow” signals in the previous zone. In the area, all Marshall posts display yellow doublewave flags and “SLOW” signs, and all illuminated signs feature the letters “SZ” surrounded by a flashing yellow border. All cars inside the zone must brake at 80 km/h until they have left the green flag waved at the end.   There is a persistent urban legend claiming that the flag originated in horse racing, but there is no basis for this myth.  Another myth claims that the first known use of the checkered flag for 19th century cycling races was in France, but this claim has no evidence either.  In the snowmobile water cross, the checkered flag is attached to the rider`s life jacket, and the rider is rewarded with a victory lap. One more ride! When the white flag flies, you are in your last turn towards the lady. This is considered a “courtesy flag” when drivers start their final lap.
Check out a summary of last weekend`s AMSOIL Championship snocross races below and see if you can spot the flags. And note that Lincoln Lemieux takes this lady! A light blue flag, sometimes with a diagonal yellow, orange or red stripe, informs a driver that a faster car is approaching and that the driver must move away to allow one or more faster cars to pass. During a race, this is usually only shown to one driver, but during practice or qualifying, it can be shown to any driver. In most series, the blue flag is not mandatory – drivers only obey it out of courtesy to their fellow riders. As such, it is often referred to as the “courtesy flag”. In other series, drivers are severely punished if they do not give in or disrupt the leaders, including stopping for the rest of the race. In Formula One, if the driver, who is about to be beaten, ignores three blue flags in a row, he must impose a drive-through penalty. The blue flag can also be used to warn a driver that another car will attempt to overtake him on the same lap.
Deliberately ignoring the black flag or black and white cross flag may result in post-race disciplinary action in addition to disqualification from the race. Fines, suspended sentences, suspensions and other penalties (for example, points attached to the championship standings) may result depending on the severity of the situation. Cars that drive at low speeds due to machine problems have a difference in speed compared to other cars, so the white flag is waved. Checkered flags were also placed at each corner of the end areas of the original Yankee Stadium when the facility was used by the New York Giants of the National Football League from 1956 to 1973. In Formula One races, a yellow flag on the starting grandstand or Marshall station indicates that there is danger “downstream” of the station. The type of display depends on the location of the danger: if a driver sees a blue flag, it means a faster car is behind him and he is on his way, according to the BBC. In all championships that use the FIA International Sporting Code, as well as in North American road races, the white flag indicates the presence of an official car such as an ambulance, fire truck, jet dryer, etc. or a competitor moving at a below-average speed in the section covered by the flag station. In Indycar, a stationary white flag means they move above 1/3 race speed while ripple means they travel below 1/3 race speed.
The “passing flag” signals slower cars to yield faster with diagonal traffic. Instruction indicators are typically used to communicate with one driver at a time. The continuous yellow flag or warning flag requires drivers to slow down due to danger on the track, usually an accident, a stopped car, debris or light rain. However, yellow flag display procedures vary by race styles and sanctioning bodies. The time at which the yellow phase begins is controversial in oval racing. Traditionally, cars were fixed in their positions when they crossed the start/finish line, but technological advances have made it possible to lock them when caution is expressed. This ended the “race for caution” where riders accelerate during the yellow flag to beat the leader to the flag. Although this practice gave lap drivers a better chance to recover their lap, it was sometimes very dangerous as it encouraged drivers to take big risks for track safety. Safety guards were unable to react to the crashes until the cars were under the control of the pilot car, which significantly slowed down their response times for potentially injured drivers.
To compensate for the loss of the race out of caution, NASCAR and several other motorsport series, both road racing and short ovals, have introduced the favor rule, which allows the best-placed car that is a full lap or more behind the leader to complete an extra lap during the caution period to make up for a lap. If the race is not subject to precautions or is delayed, it is said to be held under a green flag. However, the flag itself is usually not constantly waved by the starter. The absence of a flag on the starting stand means safe conditions with a green flag. However, the green lights are still on. The checkered flag (or checkered flag) is displayed on the start/finish line to indicate that the race is officially over. On some circuits, the first dot of the flag indicates a repeated checkered flag (usually on the opposite side of the track). The flag is usually associated with the winner of a race, as it is the first rider to “take” the checkered flag (in other words, to pass). Since the 2017 season, NASCAR has used a white and green variant of the checkered flag to indicate the end of a stage of a race. After the flag has been waved, the race is temporarily placed in caution so that drivers who have been placed in the top 10 after a stage can enter the pit lane in time.
It`s easy – running! Green indicates the start of the race. It also displays a restart after a warning. You will also see the green flag in normal race conditions. Some administrators (NASCAR and IndyCar) do not distinguish mechanical problems or unsporting behavior from rule violations and simply use the continuous black flag for all violations. The checkered flag was created in 1906 during the Glidden Tours, a road rally.  Sidney Walden divided the courts into sections; The time control at the end of each section was carried out by race directors called “checkerboards”.  These inspectors used checkered flags to identify themselves.  The earliest known photographic record of a checkered flag used to finish a race dates from the 1906 Vanderbilt Cup race on Long Island, New York.  Historically, the only way for race control to communicate with drivers was to use flags. With the advent of two-way or full-duplex radios, this is not necessarily the case. Most drivers who race on paved oval courses on short tracks do not rely on flags. Instead, they are informed of track conditions by their team leaders and observers or by flashing yellow/red lights on most oval tracks.
Sometimes, however, some drivers have to rely on the use of flags to get information when radio interference occurs. Flags are still used to tell the crowd of spectators what is going on. Dirt tracks and low-level runners are less likely to have radios than their cobbled counterparts. There are many dangers that can lead to the interruption or premature termination of a session. Many hazards such as rain, lightning, darkness, a blocked course (due to debris, water or safety vehicles), a car on fire or an accident involving several cars (especially an accident resulting in serious injury or damage to walls, fences or the surface itself that needs to be repaired) could prompt those responsible for the series to call the red flag.
