flew up only to be stuck up in the air, blocking Villeneuve's race-line vision. With his forward vision impaired, he used his peripheral vision to navigate using the yellow track markers as reference. After racing this way for minutes he used vibration on the ribbed curbing, to the point it flew off the car. This way he managed to keep control until the end of the race, without a front wing and under the rain. Mansell pitted for slicks, convinced the weather would turn. It did not. Within minutes he spun, heavily damaging his rear wing, and was pushed by marshals back onto the circuit. Driving slowly toward the L'Epingle at the northern end, he placed his JPS Lotus in the middle of the track but slowly edging to his left onto the racing line, at the braking area. Prost, on the racing line and much faster, tried unsuccessfully to avoid colliding but could not, resulting in both drivers retiring from the race. Watson was able to catch and pass Villeneuve a few laps later and the two finished second and third respectively, with Villeneuve clinching his third and last podium of the year on home soil. Bruno Giacomelli of Alfa Romeo, who had started fifteenth, came home fourth, with pole-man Piquet coming in behind him.
