From this ban alomst 4,000 drivers were fined, and some even had their cars impunded due to their reactions from the fines. But these fines and bans came out with a positive effect in the end. Congestion went down 60 percent in the capital of France, just after a few days of putting the ban into effect. The smog cleared enough for the French ruling party to rescind the ban for certain days.
