Stunning surveillance video shows a 6-year-old girl getting creamed by a bicyclist who rode around a stopped school bus with flashing lights in Brooklyn.

The 53-second clip — posted online Wednesday by The Yeshiva World — shows the bright yellow bus, with its warning lights flashing, pull up and stop diagonally across a tree-lined, residential block as a minivan and other vehicles stop behind it.

Several children hop off, including a little girl who races across the front of the bus and into the path of a man on a bike who knocks her to the pavement, scattering the belongings in her hands.

The cyclist, who appears to have hit the brakes and tried to dismount before the collision, then helps the girl to her feet and guides her as she limps toward a woman on the sidewalk.

The video ends with the bus driver, who’s wearing a traditional Orthodox Jewish outfit, confronting the cyclist and making a cellphone call.

The NYPD said paramedics took the girl to NYU Langone Hospital-Brooklyn for treatment of leg pain following the incident, which unfolded around 4:15 p.m. July 17 near the intersection of Lee Avenue and Middleton Street.

The cyclist claimed he couldn’t stop because the roadway was wet, and no charges have been filed “at this time,” cops said.

Under state law, the maximum first-time penalty for passing a stopped school bus is 30 days in jail and a $400 fine.
