The nearly full fuel tank from Woolfe's car became dislodged and landed, burning, in front of the oncoming Ferrari 312P of Chris Amon. Amon ran over it, and Woolfe's fuel tank jammed underneath causing Amon's to rupture and explode as well. Amon set off the on-board fire extinguisher and was uninjured but forced to retire the car. Debris virtually blocked the road and a number of cars were affected including the Healey, Gardner's Ford and Jabouille's Alpine. The rest of the field was virtually halted and slowly picked its way through the carnage.
