lap seven. Only those cars that arrived back at the pits under their own power would be allowed to start in the second part and there would be no changing to spare cars, though repairs and resetting of suspension and brakes for rain conditions would be allowed, and naturally everyone fitted rain tyres. During the red flag, Rebaque's was towed back by the marshals undamaged but could not join the restart, though Peterson and Reutemann drove their cars back, having been extricated from the grass verges. Patrese's Arrows was towed in with the nose cone damage, and should have been wheeled away along with Rebaque's Lotus but in the confusion the Arrows management sneaked the car into the pit lane and started repairing it, even though it was illegal. The restart was timed for 3:00 pm giving everyone adequate time to prepare their cars for a really wet track. At 2:40 pm. the pit road was to be opened to allow cars to set off on a warm-up lap, and it was to shut at 2:50 pm and anyone left behind would be out of the second part of the race. It was all quite clear, but there was some discussion as to whether Peterson and Reutemann had received outside assistance driving the first part of the race, even though they had driven their cars back to the pits. With Peterson on pole position and Reutemann in last position, having spun off on lap 5, it was a delicate situation, but was resolved by allowing them both to restart, though Reutemann would be considered to be two laps behind at the start of the second race. There should have been 21 cars lined up in pairs for the second part with Andretti, Scheckter, Rebaque and Piquet already out but there were 22 cars on new grid due to the Arrows team's shady tactics for Patrese. Race restart The race restarted at 3:15 pm after the rain relented, and once again Peterson led followed by Depailler and Lauda. As the track began to dry, Peterson started to pull away, and behind, Reutemann was on a charge and passed Lauda for third but he was black-flagged for receiving outside assistance, and Lauda crashed out soon after, leaving Gilles Villeneuve third. The drivers changed to slicks but the top 3 remained the same and stayed so till the end; Peterson winning ahead of
