Former Formula One driver Clay Regazzoni was killed in a road accident in Italy on Friday, police said.
The Swiss-born racer, who gave Williams their first grand prix victory at Silverstone in 1979 and won four races for Ferrari, was 67.
Police said Regazzoni, who was paralysed after breaking his back in a crash at the 1980 U.S. Grand Prix West in Long Beach, died when his car collided with a truck on a highway to the west of the Italian town of Parma.
"Clay won the very first Grand Prix for the Williams Team in 1979 at Silverstone," said Frank Williams. "This was probably the most important event ever to occur in the history of our time in Formula One.
