The Proctors were about to start a "holiday of a lifetime"
The family of a father and son who were killed in a crash as they drove to Manchester Airport for their summer holiday have paid tribute to them.
Gary Proctor, 47, and his son James, 16, from Wakefield, West Yorkshire, suffered fatal injuries in the crash on the M62 in the early hours of Sunday.
Catherine Proctor, 44, Gary's wife and James's mother, suffered broken ribs and a broken arm.
Their family said they were about to set off for a "holiday of a lifetime."
The Proctors had been driving to Manchester Airport to fly to the United States.
The Fiat Punto they were travelling in collided with an Audi Quattro on the M62 eastbound just before 0600 BST on Sunday.
Gary and James were taken to hospital but their injuries were too severe to save them.
Police said the Audi had previously been seen driving at speed along the carriageway by drivers in the West Yorkshire area.
The driver of the Audi, a 31-year-old man, has since been arrested on suspicion of causing death by dangerous driving and driving with excess alcohol and is being questioned by police.
Members of Gary and James's family said: "They both really loved sport and they were both season tickets holders for the Leeds Rhinos rugby league team.
"James was a lovely, smashing lad. He was really thoughtful and very clever. He loved sport, in particular cricket, snowboarding and golf.
"He had saved his pocket money with the intention of buying a new set of golf clubs while on holiday in America.
"Gary and James regularly played golf together."
They added: "Gary was quiet and unassuming, with a good sense of humour and loved a laugh. Both he and Catherine idolised James. They were looking forward to the holiday of a lifetime.
"We are in total disbelief. You say the words, but it just does not seem real."
Insp Andy Hudson, of Greater Manchester Police, described the crash as an "absolute tragedy".
"We need anyone who saw this Audi being driven, possibly at speed, along the M62 westbound early this morning to call us straight away," he said.
"You might have information that is vital to our investigation."
