Officers are appealing for witnesses after a car and lorry crashed on the A1065 at Cockley Cley, near Swaffham.
The incident took place at around 5.30am on Wednesday, May 2 when a yellow HGV lorry was involved in a collision with a silver Citroen Xsara.
Both the driver and passenger of the car were uninjured but left very shaken.
The lorry driver, a man in his 70s from the Hunstanton area, was arrested on suspicion of dangerous driving.
He has since been released on police bail pending further enquiries.
Road policing officers would like to speak to the driver of a blue HGV lorry who was in the area at the time of the crash and are keen to trace the driver of a green or blue car which is believed to have been in the area just before it happened.
Anyone with information should contact PC Mark Howes at Swaffham Roads Policing on 101.
