The family of a 24-year-old man who died in a crash on the M4 early on Sunday said they hope his death acts as a warning to his friends who drive.
James Walker, known as Scott, from Swffryd, Blaenau Gwent, was killed in a collision with a lorry at around 0440 GMT between junctions 24 and 25.
His parents, Stephen and Susan, said they would like him to be remembered as someone who "lived life to the full".
In a statement issued via Gwent Police, they thanked people for their support.
The westbound carriageway of the motorway was shut for nearly seven hours for the police investigation in to the collision.
Gwent Police said the incident involved two vehicles, a silver Seat hatchback car and a tanker lorry, and that a 24-year-old man travelling in the car was pronounced dead at the scene.
Mr Walker's parents said they would like Scott to be remembered by everybody who knew him as the kind and loving boy that he was and someone who always lived life to the full.
The statement read: "The only positive that can be gained from Scott's tragic and untimely death is that no one else was hurt or killed in the accident and that the way in which he died would act as a warning to all his friends who drive."
