Fatal accidents to competitors at the Hockenheimring circuit during the German Grand Prix and other national and international motor-sport events. The circuit was first used in 1932 using the Hockenheim "triangle course". It was rebuilt in 1938 into the "Kurpfalzring" (oval course) with the addition of the "Motodrom" stadium section in 1964. Metal Armco barriers and chicanes were added in 1970 and a further chicane added in 1980 at the site of the Ost-Curve. The Hockenheimring was shortened to a Grand Prix circuit used from 2002 onwards.
