Two of New York City’s firefighter unions are criticizing the city’s newly-implemented congestion pricing plan, stating at a press conference on Sunday that the $9 toll will hurt response times and hike overtime fees.

The tolling program, the first of its kind in the United States, was introduced just after midnight on Sunday, and imposes a $9 toll on drivers entering Manhattan’s busiest areas.

FDNY unions are sounding the alarm on the city's new congestion pricing, warning it could delay response times and have deadly side effects as a result.

Congestion pricing is underway, but some unions say the toll is putting the health and safety of New Yorkers at risk. The president of the Uniformed Fire Officers Association and James Brosi and president of Uniformed Firefighters Association Andrew Ansbro explain why.
