The 11-year-old boy was left fighting for his life after he was his by two cars on Nabbs Lane, at the junction with Godber Road, on Tuesday night.
The boy, who is believed to be from the area, was struck by an Iveco Daily van and Audi A4 Quattro.
A police spokesman said he was taken straight to Nottingham’s Queens Medical Centre with “life-threatening” injuries - where he currently remains.
But before the fire service arrived at the scene, paramedics were struggling to treat the boy - leading 12 nearby people to lend a hand.
A spokesman for East Midlands Ambulance Service said:“On arrival, paramedics realised the boy had suffered very serious injuries but they could not treat him as he was trapped under a car.
“They have asked us to pass on their thanks to around 12 onlookers who physically lifted the car off the casualty because their actions saved valuable minutes and allowed crews to provide life-saving clinical care.”
The onlookers lifted the Audi A4 Quattro from its wheel arches and pushed the car backwards from the bonnet.
The van involved in the collision was also parked nearby.
Several Hucknall residents have also been in touch to show their support for the boy and his family.
There have also been numerous calls to launch a campaign for traffic calming measures in the area.
One petition has already been set-up calling for a zebra crossing on the road.
The petition states: “This petition is to present our need for at least one zebra crossing on Nabbs Lane for us, our children and the most vulnerable amongst us; to cross the road safely. Especially as there is a children’s park on Nabbs Lane, where it is believed the boy was leaving from. This is the most serious case to my knowledge but there have certainly been other children ran over on this road.”
