A 43-year-old man died this morning when the car in which he was a passenger crashed in icy conditions.
Humberside Police said the accident happened shortly before 5.20am on the B1248, close to the village of Tibthorpe, west of Driffield.
The Peugeot 406 was being driven by a 27-year-old Hull man who suffered minor injuries.
Three other men, aged 23, 25 and 52, suffered "non-life threatening" injuries.
The car came off the road and hit a tree, say police.
Inspector Mark Hughes said he believed the wintry weather was to blame.
He added: "At this time we have had no witnesses to the collision come forward and it is vital that anyone who saw the vehicle, prior to the collision, or who may have seen what happened, calls police immediately on 101."
