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.

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.

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.

The FDNY will be forced to use firetrucks and other heavy vehicles to move firefighters around the city because smoke eaters will no longer want to drive their personal cars into manhattan, warned

Uniformed Firefighters Association president Andrew Ansbro and Uniformed Fire Officers Association Jim Brosi join 'Fox & Friends' to explain their efforts against the newly implemented congestion pricing and the impact the toll will have.

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.

Meanwhile, New York’s bravest are sounding the alarm on congestion pricing. Union leaders say this could slow down the response time of first responders arriving at a fire. FOX 5 NY’s Meredith Gorman has the details.
