Several other U.S. cities have implemented taxi fuel surcharges. Non-regulated industries have raised prices because of higher gas costs.
The TLC has granted taxi drivers two fare increases since 2004.
The city's 43,000 yellow cabbies each put about 20 gallons of gas per shift, according to the taxi alliance. And the drivers say they are losing more than $1,000 monthly because the TLC won't help them.
