In a session that would see the drivers struggle to match the times set during Friday practice the BMW WilliamsF1 drivers of Mark Webber and Nick Heidfeld would set times that would see them in sixth and seventh. It was a sesion that would see the track damp in places after rain had hit the track.

The third practice session for the French Grand Prix would see Minardi's Patrick Friesacher take to the track first, followed by team-mate Christijan Albers. Both drivers would complete their installation lap as others also took to the track including the Renaults of Fisichella and Alonso, and both McLaren's of Montoya and Raikkonen.

Also completing their installation lap was the Jordan pair of Karthikeyan and Monteiro. With ten minutes of the session run no driver had set a time and neither BMW WilliamsF1's Mark Webber or Nick Heidfeld had taken to the track.
Both Toyota's had also come out. Nick would take to the track and would set the fastest first sector time, 28.4 seconds, followed by the fastest second sector time, 31.8 seconds. He would complete the lap setting a time of 1m:30.935 to go fastest but well on the pace of the Friday practice. He would improve this with a 1m:30.272. Massa had also come out for his installation lap.

With twenty five minutes of the session remaining only Nick had set a time. Fisichella would set a time of 27.1 seconds for the first sector, followed by 30.4 for the second. He would finish with a time of 1m:26.798 to go fastest. He had completed five laps but only set a time on one of them. Team-mate Alonso would set his first lap time, a 1m:26.904 to move into second. Fisichella would improve his time with a lap of 1m:26.651.

Raikkonen would complete his first lap setting a time of 1m:27.123 to be in third, with twenty minutes of the session remaining. Mark Weber had taken to the track to complete his installation lap. Kimi would improve his time to go fastest with a lap of 1m:26.483 but Alonso would take this spot with a time of 1m:25.934. But compared to de la Rosa's time of 1m:14.460 these times were very slow, with the drivers suffering from a lack of grip due to the wet conditions.

Mark Webber would set his first lap time, a 1m:28.425, fifth position, while BAR's Jenson Button was in fourth with a 1m:27.344. Nick was now down in sixth, but the German would improve to move ahead of Mark with a 1m:27.510. Albers would set a time of 1m:31.872.

With fifteen minutes of the session left it was Alonso from Raikkonen,
Fisichella, Button, Heidfeld and Webber. Red Bull's David Coulthard was out and he would move into fourth with a time of 1m:27.019. Ten minutes remaining and neither Ferrari had taken to the track. Klein would come out to be the only driver on the track. But Mark would come out with five minutes of the session remaining.

Mark would set the fastest first sector, a 26.8, followed by a slow second sector, 30.9, to complete the lap with a time of 1m:27.313 to move into sixth ahead of Nick. Fisichella was out on a quick lap and would finish with a time of 1m:24.922 to move ahead of his team-mate and go fastest. Friesacher was in eighth. After completing an extensive number of laps on Friday it appeared that most drivers were limiting their track time.

Alonso would take the top spot away from his team-mate with a time of 1m:23.939 as the session came to a close. Only nine drivers would set a time during the session, Alonso followed by Fisichella, Raikkonen, Coulthard, Button, Webber, Heidfeld, Friesacher and Albers.
