Vanletino Rossi won the 500cc Grand Prix at Rio, which was red-flagged after four laps for rain, then restarted to run another 20 laps on a drying track (Rossi turned the fastest lap of the race, 1:53.258, on lap 20 of 24).

Crashers included Shinya Nakano (who restarted), Oliver Jacque, Jurgen van den Goorbergh, Sete Gibernau (who restarted), and Tohru Ukawa. Kenny Roberts pitted shortly after the restart, then rejoined the race.
