The 14-year-old boy who died after being found unconscious on the side of the M67 motorway has been named as Samuel Berkley.
The teenager died from his injuries after being involved in a collision with a grey convertible BMW near Junction 3 at Hyde, Greater Manchester, around 5:25pm on 1 December.
The boy, who played football for youth side Hattersley FC, was found in a critical condition and was taken to hospital before he later died from his injuries.
The driver of the car did stop at the scene and spoke to police about the incident.
His family have said they are "heartbroken" at their loss of the boy who attended Audenshaw School.
In a statement released via police, they added "Although nothing will ever replace losing Sam [we] hope everyone remembers him for the fun, outgoing and friendly boy he will always be."
Samuel lived at home with his parents Sarah and Gary in Denton.
He has a big brother called Scott, 21, and an older sister called Charlie, 20, and had just become an uncle to his brother's new baby, Lilly.
Police are still appealing for anyone who was driving on the motorway that evening who may have seen a pedestrian on the road to get in touch.
Sergeant Lee Westhead, of GMP's Serious Collision Unit, said: "My thoughts are with the victim's family who are being looked after by specially trained officers at this difficult time.
"Whilst we work to uncover how this has happened and piece together the moments before the collision, I am asking the public to help in any way that they can.
"If you were in the area at approximately 5.25pm on December 1 and saw a pedestrian on the motorway, or have dashcam images, please get in touch and share this information."
