Jarno Trulli has praised the FIA for its calls during last Sunday's action-packed Canadian Grand Prix.
The race started behind the safety car after a downpour had hit the track, and was red-flagged later because of more torrential rain.
The race direction restarted the event behind the safety car two hours after the stoppage, with a total of five safety car periods on the day.
Lotus driver Trulli believes the FIA made all the rights calls during a difficult race.
"It wasn't easy to race, but neither was managing the progress of the race," wrote Trulli in his column for Repubblica newspaper.
"I think that, never as much as today, the FIA must be applauded. It did not make a wrong decision and got everything right: the start behind the safety car, deployment of it when there was debris or cars standing still on the track, the red flag interruption when it was too dangerous, and then the restart after more than two hours.
"It was right to wait that long: track conditions had to improve in order to make the cars drivable again. They did everything right.
"Obviously confusion reigned supreme, and someone may think it's too much, but Montreal is a different race from all the others.
"That's Canada: Formula 1 and its new rules have nothing to do with it. It's the nature of that track that makes you make mistakes: the deluge did the rest by increasing the difficulties."
