Four days into New York City's controversial congestion pricing plan, and police have already busted dozens of drivers trying to figure out ways to cheat the new toll.

With congestion pricing now in effect in NYC, officials are cracking down on obscured license plates, or "ghost plates," to avoid the toll.

The crackdown could include a $50 fine for parked cars with obstructed plates, in addition to penalties for those caught driving through toll areas undetected.

The toll, known as congestion pricing, is meant to reduce traffic gridlock in densely packed Manhattan while also raising money to help fix the city’s ailing public transit infrastructure. It formally took effect Sunday.

One day after New York City completed its first full weekday of the new congestion pricing tolling program, police are cracking down on motorists trying to bypass the system. Assisting the MTA, the NYPD stopped several drivers who tried to cover up parts of their license plates to avoid being charged as they entered the congestion zone.

Three days after congestion pricing began, officials are already tackling toll evasion and cracking down on drivers breaking the law. One city council member is also facing criticism after explaining how to disable the cameras.

Anticipating a rise in so-called "ghost vehicles" with the advent of congestion pricing, New York City officials are looking to give police more leeway to go after drivers who hide or obstruct their license plates.

The NYPD is warning drivers not to fake or cover their license plates before entering the congestion pricing zone in Manhattan. The agency’s Transportation Bureau posted two photos to X on Tuesday of two license plates – both showing tape covering one letter.

New York City officials say they will ramp up enforcement efforts against drivers trying to evade the new $9 congestion pricing toll by obscurig their license plates. FOX 5 NY's Linda Schmidt has the story.
