Elio de Angelis' Lotus dived left to avoid Fabi and was hit by the Ferrari of Michele Alboreto. Fabi suffered damage as did the Arrows-BMW of the second Austrian driver in the race Gerhard Berger. Luckily for those with damaged cars (especially championship leader Alboreto) the first lap was declared null and void and the race was completely restarted meaning those with damaged cars were permitted to start in the team spares. Lucky too was Prost who was able to change cars after his McLaren had developed a misfire. Piercarlo Ghinzani became a non-starter in his Toleman after team mate Fabi took over the spare TG185 for the race as he had qualified 6th while Ghinzani started 19th. This left Ghinzani without a drive. On lap 13 Andrea de Cesaris survived one of the biggest crashes ever seen in Formula One when his Ligier-Renault turned sideways at the left hand Panorama Curve and slid onto the outside grass at high speed. The grass, wet from overnight rain caused the Ligier to initially slide sideways before his right rear hit a slight bank launching the car into a series of rolls with de Cesaris's head bouncing around freely in the cockpit. Somehow as soon as the Ligier came to a rest, de Cesaris undid his seat belt and walked away with nothing more than a mud-splattered helmet and driving suit. When he returned to the pits, the Ligier team had not yet seen a replay of the accident, and de Cesaris told the team that the car had stalled and wouldn't restart. However, the crash was the end for de Cesaris at Ligier, with team owner Guy Ligier firing the Italian after he saw a replay of the crash stating "I can no longer afford to keep employing this man" referring to the constant repair bills from de Cesaris's crashes since he joined the team in . With his 20th career victory, Prost moved into a shared lead in the World Drivers' Championship alongside Alboreto, with each having 50 points. After a string of non-finishes since his win in the second race of the season in Portugal, Senna drove a great race into second from a lowly (for him) 14th on the grid, with Alboreto finishing third in the spare Ferrari to retain his lead in the World Championship (now shared with Prost).
