This is the shocking moment a car reversed out of control and crashed into a parked vehicle.

Mr Mei was navigating a narrow road when he saw the black Cadillac blocking the way, with a man standing outside the car at Panzhihua Park in Sichuan, China.

The lad in a black shirt can be seen guiding the driver to park the four-wheeler, but it suddenly lurched backward on October 25.

Dashcam footage shows the Cadillac accelerating rearward, knocking the man aside.

It then continued reversing up the slope and over the ledge before swerving and colliding with the front of the white sub-SUV.

The female driver then engaged the brake while the man was seen knocking on the window to check if she was okay.

No one was reportedly injured in the incident.
