A father and son have died following a crash on the M62 near Manchester which involved a car seen moments earlier driven at "high speeds", police said.
An Audi Quattro, which was reported speeding at 0550 BST, collided with a Fiat Punto at Birch services.
Gary Procter, 47, and son James, 16, who are from Wakefield and were in the Punto, suffered fatal injuries. A woman in the car suffered serious injuries.
The M62 was shut westbound between junctions 19 and 18 until 1615 BST.
A 31-year-old man has been arrested over the crash.
Police said he was being held on suspicion of dangerous driving and driving with excess alcohol and remains in police custody for questioning.
The 44-year-old woman who was injured in the Punto suffered broken ribs and a broken arm and is in a serious but stable condition in hospital.
All three occupants were on their way to Manchester airport to catch a flight on holiday when the crash happened.
Insp Andy Hudson said: "This is an absolute tragedy for this family who had been on their way to Manchester airport to start a summer holiday in America. My thoughts are with them all.
"We need anyone who saw this Audi being driven, possibly at speed, along the M62 to call us straight away. You might have information that is vital to our investigation."
