The NYPD will crack down on abuse of city-issued parking placards with beefed-up fines and violations starting on Monday, The Post has learned.

“WARNING!!” police brass told rank-and-file cops in an e-mail notice Sunday. “Due to new laws passed by the city council on placard abuse, multiple units are tasked to enforce and document the abusers by taking photos of cars, plates and placards to record and submit to [the Department of Investigation].

“Cant stress this enough for you to tell your personnel that this will commence Monday 1/6/2020!” the email continued. “Be Safe!”

Additional units will be out tracking misuse of the placards and issuing two tickets to violators — one for illegal parking and another for misuse of the placard.

The placards allow bearers to defy some city parking regulations when executing their job duties, but cops and other offenders sometimes use them to “park by their homes and when going places off duty” with impunity — including Yankee Stadium, Madison Square Garden and Bloomingdales, a law enforcement source said.

But another source griped that cops should be allowed to continue bending the law.

“The whole thing is ridiculous. I think we have bigger things to worry about. You got bail reform. You got bad people on the street. They’re having a hate problem in the Jewish areas. Maybe they should be guarding the synagogues instead of going after parking placard problems. Maybe they should put more guys in Morningside Park. They should use their traffic cops,” the high-ranking police source told The Post, referring to a spate of anti-Semitic crimes rocking the city, as well as the still unsolved murder of Barnard College freshman Tessa Majors.

City Council Speaker Corey Johnson pitched the heightened enforcement in November and received overwhelming support from the rest of City Council.

Lawmakers called for the fine for illegal placard use to be bumped from $250 to $500, and the maintenance of an electronic database of all placards in circulation to track down improper use.

The placard enforcement unit already has a list of nearly three dozen areas where the worst abuse occurs, including around City Hall and the federal courthouse and jail. That list was shared with rank-and-file in the email sent out by police leaders Sunday.
