context_page_description: The 24 Hours of Le Mans is the world's oldest active sports car race in endurance racing, held annually since 1923 near the town of Le Mans, France. It is considered one of the most prestigious automobile races in the world and has been called the "Grand Prix of Endurance and Efficiency". The event represents one leg of the Triple Crown of Motorsport, other events being the Indianapolis 500 and the Monaco Grand Prix. Unlike fixed-distance races whose winner is determined by minimum time, the 24 Hours of Le Mans is won by the car that covers the greatest distance in 24 hours. Racing teams must balance the demands of speed with the cars' ability to run for 24 hours without mechanical failure. In the 2019 race, 47 of the 61 qualifying cars ran the full duration.
  The race is organized by the Automobile Club de l'Ouest and is held on the Circuit de la Sarthe, which is composed of closed public roads and dedicated sections of racing track.
  The 24 Hours of Le Mans was frequently part of the World Sportscar Championship from 1953 until that series' final season in 1992. In 2011, it was a part of the Intercontinental Le Mans Cup.
context_section_description: Although it has been a part of the World Sportscar Championship for most of its existence, the race has had different regulations for safety and competition reasons partly due to its length. For many decades, cars were required to run at least an hour into the race before they were allowed to refill fluids for the car, such as oil or coolant, with the exception of fuel. This was an attempt by the ACO to help increase efficiency and reliability. Those who could not last the first hour without having to replace lost fluids risked disqualification.
  Another rule unique to Le Mans is that cars must be switched off while they are refuelled in the pits. Not only is this safer and less of a fire hazard, but it is also another test of reliability, as cars with the guaranteed ability to restart many times under race conditions are harder to make. Another element of this rule is that mechanics are not allowed to work on the car while it is being refuelled (other than helping a driver in or out of the car), which has led teams to adapt innovative ways in which to decrease the time of these lengthy pit stops. Drivers are allowed to get out of the car and be replaced by another driver during refuelling. Those rules are also in application in the FIA World Endurance Championship.
  There are various long-standing traditions at Le Mans, including the waving of the French tricolor to start the race. This is usually followed by a fly-over featuring jets trailing blue, white and red smoke. A similar flag tradition is the waving of safety flags during the final lap of the race by track marshals, congratulating the winners and other finishers.
  Le Mans was the venue for the first televised instance of a winning driver celebrating by spraying champagne instead of drinking it. When Dan Gurney won the 1967 race with co-driver A. J. Foyt, the two drivers mounted the victory podium and Gurney was handed a magnum of champagne. Looking down, he saw Ford CEO Henry Ford II, team owner Carroll Shelby and their wives, as well as several journalists who had predicted disaster for the high-profile duo. Gurney shook the bottle and sprayed everyone nearby. Gurney autographed and gave the bottle of champagne to Life photographer Flip Schulke, who used it as a lamp for years before returning it to Gurney.
