So far in 2007, the prefecture has imposed 155 fines totaling 78,466 euros, with most offenses involving customers being overcharged or taxi drivers refusing to accept a customer based on their destination. Each fine is between 300 to 1,000 euros and is often accompanied by the temporary revocation of the taxi license.
