A car and a motorbike came off the road and ended up in a field after a collision on the A149 north of Thorpe Market, near Cromer, this morning.

No-one was injured in the accident which happened on a stretch of the road notorious for its bends and which, this morning, was visibly icy.

A police spokesman warned drivers to take care. She said: 'On mornings like this, please be vigilant, as there might be ice on the road, and adapt your driving to the conditions.'

A spokesman for Norfolk County Council said the gritters went out at 6pm last night and would have gritted all A-roads. As there was no rain overnight, they had not gone out again this morning.
