Motorists warned as thick fog and ice causes collision
Drivers are being warned of treacherous road conditions, after a six-vehicle crash in north Lincolnshire.
The collision on the southbound carriageway of the A15, just south of the Humber Bridge, closed the road for part of the morning.
Humberside Police said nobody was seriously injured.
In East Yorkshire, gritters worked through the weekend to clear hundreds of miles of roads after 5-10cm (2-4in) of snow fell.
East Riding Council said major routes had been kept clear but some minor roads were not treated.
