 when he belatedly noticed a pit signal to stop for fuel. Hawthorn slowed suddenly in an effort to stop rather than make another lap. Hawthorn's Jaguar, with the new disc brakes, slowed much more quickly than other cars using drum brakes, such as Levegh's Mercedes. The sudden, unexpected braking by Hawthorn caused Macklin in the Healey to hit his brakes, throwing up a small cloud of dust in front of Levegh, who trailed close behind. Macklin then swerved across the centre of the track, attempting to re-pass the slowing Jaguar, but also apparently out of control. Macklin had not noticed both Levegh and Juan Manuel Fangio

, in another 300 SLR, approaching rapidly from behind. Fangio was in second place at the time, but directly behind, and attempting to lap Levegh.

Levegh, ahead of Fangio on the track, did not have time to react. Levegh's car made contact with the left rear of Macklin's car as he closed rapidly (at about 150 mph) upon the slowed car. The aerodynamic design of the Austin-Healey featured a long, ramp-like rear. When Levegh hit the Austin-Healey from behind, his car became airborne, soaring towards the left side of the track, where it landed atop the earthen embankment separating spectators from the track itself.

Collision

Levegh's 300 SLR struck the mound at such speed and angle that it was launched into a somersault, which caused some parts of the car, already damaged and loosened by the collision, to be flung from the vehicle at very great speeds. This included the bonnet

, both of which separated from the frame and flew through the crowd. The bonnet decapitated tightly jammed spectators like a guillotine. With the front of the spaceframe chassis—and thus crucial engine mounts—destroyed, the car's heavy engine block also broke free and hurtled into the crowd. Spectators who had climbed onto trestle tables to get a better view of the track found themselves in the direct path of the lethal debris. Levegh was also thrown free of the tumbling car, fatally crushing his skull when he landed.

As the remains of the 300 SLR slowed its somersault, the rear-mounted fuel tank ruptured. The ensuing fuel fire raised the temperature of the remaining Elektron

 content was already very low. The alloy burst into white-hot flames, sending searing embers onto the track and into the crowd. Rescue workers, totally unfamiliar with how to attack a magnesium fire, poured water on the inferno – greatly intensifying the fire. As a result, the car burned for several hours. Official accounts put the death total at 84 (83 spectators plus Levegh), either by flying debris or from the fire, with a further 120 injured. Other observers estimated the toll to be much higher.

Fangio, driving behind Levegh, narrowly escaped the heavily damaged Austin-Healey, which was now skidding to the right of the track, across his path. Macklin then hit the pit wall and bounced back to the left, crossing the track again. He impacted the barrier near the location of the now burning 300 SLR, causing the death of another single spectator, although Macklin survived the incident without serious injury.

Conclusion of the race

The race was continued, officially in order to prevent departing spectators from crowding the roads and slowing down ambulances. In the immediate wake of the disaster, an emergency midnight meeting of the Daimler-Benz board of directors was convened. The Daimler board, mindful of sensitivities involving German cars in a French race just 10 years after the end of World War II, made their decision. Eight hours after the accident, the official order came through: pull out. The two remaining Mercedes cars, driven by Juan Manuel Fangio/Stirling Moss

After the race

After the race the French press carried photographs of Hawthorn and Bueb celebrating their win with the customary champagne but treated them with scorn.

Nevertheless, an official inquiry into the accident ruled that Jaguar was not responsible for the crash, and that it was merely a racing incident. The death of the spectators was blamed on inadequate safety standards for track design, leading to a ban on motorsports in France, Spain, Switzerland

s, a race which allowed two cars to compete alongside one another. This forced Swiss racing promoters to organize circuit events in foreign countries including France, Italy, and Germany. In 2003 the Swiss parliament started a lengthy discussion about whether this ban should be lifted. The discussion focused on traffic policy and environmental questions rather than on safety.

won both of these events, and were able to secure the constructors championship for the season.

Opinions differed widely, amongst the other drivers, as to who was directly to blame for the accident, and such differences remain even today. Levegh's co-driver, John Fitch, became a major safety advocate and began active development of safer road cars and racing circuits. At the Le Mans circuit itself, the Grandstand and pit areas were demolished and rebuilt soon after.

After also winning the last major race of the 1955 season, the Targa Florio, Mercedes-Benz announced that they would no longer participate in factory sponsored motorsport in order to concentrate on development of production cars. The self-imposed ban on circuit racing lasted until the 1980s. The Jaguar works racing team also closed down a few months later and did not return to Le Mans for over thirty years. Two drivers, Fangio and Jaguar's Norman Dewis, never raced at Le Mans again.

Macklin had regarded Hawthorn as a friend; but, when he read Hawthorn's autobiography "Challenge Me The Race" in 1958, he was embittered to find that Hawthorn disclaimed all responsibility for the accident without identifying who had actually caused it. With Levegh dead, Macklin presumed that Hawthorn's implication was that he (Macklin) had been responsible, and he began a libel action. The action was unresolved when Hawthorn was killed in a crash on the Guildford bypass in 1959.
