Standing start
A standing start is a type of start in auto racing events, in which cars are stationary when the race begins. Some categories of land speed record also require a standing start, although the absolute land speed record uses a flying start, where the vehicle has reached its top speed by the starting point of the timer.
Procedure
In a standing start, cars are completely still but with their engines running when the signal is given to start the race. This is often preceded by a set number of lights. Standing starts are common in many motorsports, including most single-seater, Touring Cars, drag racing, the Supercars Championship, kart racing, and many types of short-course off-road racing. In a typical standing start, the formation lap takes place, giving time for team personnel to get clear of the starting grid and back into the pit boxes. Once the formation lap is over, all cars position themselves in the order that they qualified, and the Medical Car positions itself behind the pack. Once the Medical Car is in position, a light system consisting of five lights will be shown, and in the process, a marshall walks or runs across the grid while waving a green flag to signal that all cars are correctly positioned. After a predetermined number of seconds, the lights go out, and the race is underway. However, first-lap crashes are common.American-based series such as IndyCar, NASCAR, and SCCA have traditionally utilized rolling starts. During the 2013 and 2014 seasons, the IndyCar Series adopted a rule for standing starts on a trial basis for selected events. IndyCar dropped the procedure after the 2014 season, due to numerous start aborts and a start-line crash at the 2014 Grand Prix of Indianapolis.
Le Mans
A Le Mans-style start was used for many years in various types of motor racing. When the start flag dropped, drivers had to run across the track to their cars which were parked on the other side, climb in, start the car, and drive away to begin the race.Such starts were unsafe, with drivers usually postponing the donning of safety equipment such as seat belts and not checking their vehicles in order to drive as soon as possible. Drivers also ran the risk of colliding with other vehicles as they took off. Britain's RAC prohibited the use of the Le Mans start in English racing in late summer 1962 for this reason. In 1969, Jacky Ickx, who always considered this type of start to be dangerous, decided to walk to his car instead of running. Taking the time to secure everything made him effectively start in last position; however he still went on to win the race. Minutes later, John Woolfe died after crashing in the first lap at the Maison Blanche curve, as he did not fasten his seat belt prior to taking off. Both incidents led to the running start being abolished the following year. As a result, they are no longer used in any motorsport except for endurance motorcycle racing, such as the Suzuka 8 Hours and the 24 Heures Moto, bicycle endurance races, and, in nitro powered radio-controlled racing, except when they are held above the ground until race start by their mechanics.
A Le Mans start variation called a "land rush start" is used at short course off-road races at Crandon International Off-Road Raceway, where the vehicles start lined up side-by-side on a wide part of the track. The "land rush start" is based on the 1970 24 Hours of Le Mans start, and is used in historic races at Le Mans in some situations. However, unlike the true Le Mans start, engines are already running and the drivers are already sitting behind the wheel, wearing their safety belts, when the starting signal is displayed.
A second variation is used in the endurance races at Highlands Motorsports Park in New Zealand that integrate the Le Mans start and the Land Rush start for multiple driver races. The primary drivers are in their cars at the start on pit lane, with the engines running, with each car having a flag attached to the rear of the cars. Co-drivers are positioned about from their cars in uniform with a marshal next to them, lined up in qualifying order of their cars. At the signal from a starting pistol, the co-drivers make the run from the start line to their cars, pulling the flag from their car once they reach their respective cars, with the primary driver then moving the car only after the flag is pulled. Drivers must stay at pit speed limits until they exit pit lane.
