At the start Piquet went into the lead but halfway around the lap there was a big accident at Bottom bend as Riccardo Patrese (Alfa Romeo) tried to pass Jacques Laffite's Williams-Honda. The Italian spun. This caused his team mate Eddie Cheever to lift off. Behind him Johansson did the same but Philippe Alliot in the RAM did not have time to react and went into the back of the Tyrrell and then flew over it, landing on the rear of Cheever's car. Also involved was Gartner who tried to avoid the crash and ended up in the tire barrier.
