A chicane (/ʃɪˈkeɪn/) is a serpentine curve in a road, added by design rather than dictated by geography. Chicanes add extra turns and are used both in motor racing and on roads and streets to slow traffic for safety. For example, one form of chicane is a short, shallow S-shaped turn that requires the driver to turn slightly left and then slightly right to continue on the road, requiring the driver to reduce speed. The word chicane is derived from the French verb chicaner, which means "to create difficulties" or "to dispute pointlessly", "quibble", which is also the root of the English noun chicanery. The Spanish verb chicanear also means "to use trickery".

Chicane in the context of 24 Hours of Le Mans
The 24 Hours of Le Mans (French: 24 Heures du Mans; French pronunciation: [vɛ̃t.katʁ‿œʁ dy mɑ̃]) is an endurance sports car race held annually near the city of Le Mans, France. It is widely considered to be one of the world's most prestigious races, and is one of the races – along with the Monaco Grand Prix and Indianapolis 500 – that form the Triple Crown of Motorsport, and is also one of the races alongside the 24 Hours of Daytona and 12 Hours of Sebring that make up the informal Triple Crown of endurance racing. Run since 1923, it is the oldest active endurance racing event in the world.
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. The cars on this track are able to achieve speeds of 366 km/h (227 mph), and reached 407 km/h (253 mph) on the Mulsanne Straight in 1988 – instigating the addition of more chicanes to the track to reduce speed reached. Racing teams must balance the demands of speed with the cars' ability to run for 24 hours without mechanical failure. The race is organized by the Automobile Club de l'Ouest (ACO). It is held on the Circuit de la Sarthe, composed of closed public roads and dedicated sections of a racing track.
