Starting Monday, a team of parking cops will “reluctantly” roam the city with specific instructions to ticket illegally parked police vehicles and officers’ personal cars.

The initiative ordered last month by Mayor de Blasio will consist of eight sergeants, eight officers and a rotating cast of traffic agents.

Their job will be to ticket parking placard-abusing employees of all city agencies.

They’ll focus on illegally parked NYPD vehicles, and on private cars with department-issued parking placards.

Ticket-worthy offenses will include double parking and parking on a sidewalk or at a fire hydrant, crosswalk or bus stop. Police cars on official business will get some leeway, a law-enforcement source said.

But team members are chafing at having to ticket fellow officers, who, for as long as anyone can remember, have been able to put a city parking placard in their civilian-car windshield and park pretty much anywhere with impunity.

“These guys are not liking that they have to go out and write summonses on department vehicles,” a source told The Post. “All this is going to do is cause bad blood and issues with morale.”
