Levistre was driving in front of Diana's Mercedes when the collision happened in the Alma underpass in Paris.
Mr Levistre described how a motorbike had overtaken the princess's car in the tunnel.
Levistre then saw a very bright flash, which had been directed at the Mercedes.
Mr Levistre said: "I realised there was this major white flash of the motorbike in front of the Mercedes, in front of the car.
"I was nearly at the exit of the tunnel and I realised that because I heard the noise of the motorbike within the tunnel...
"The light was not directed towards me. It was directed towards the car which was behind."
Mr Levistre said he had stopped near the exit from the Pont de l'Alma tunnel following the accident.
He saw the motorcycle passenger get off the motorbike, approach the car, and then gesture to the bike's driver before climbing back on and driving off.
