People are being urged not to film crashes caused by the snow this morning.

Police and emergency services have put out the warning after becoming aware that people are filming accidents on their mobile phones, putting themselves and others at risk of further crashes.

Harry Mitchell, head of news at the police, said: 'Filming road traffic incidents is extremely dangerous for both drivers and our officers and staff who are attending people in need.

'In these difficult driving conditions it is more important than ever that drivers stay in full control of their vehicles. Filming these incidents means drivers are distracted from watching the car in front and they could cause their own crash.'

A number of crashes has been reported in the county, including an accident on the A47 Norwich bound at Dereham, the A11 northbound at Wymondham, near the police headquarters at in Wymondham and in Bunwell Road, Besthorpe.

There have also been crashes in Attleborough Road, Rockland All Saints, Buxton Road, Spixworth, Rectory Road, Edgefield, and on the A149 at Rollesby.

Drivers are being reminded to make sure all their car lights are working, ensure all windows are fully cleared of snow, keep windscreen washer fluid topped up.

They are also being urged to make sure they have sufficient fuel for their journeys, give extra time for travelling and to take a fully charged mobile phone.

Anyone who gets stuck in the snow is asked to park it out of the way of traffic, leave a contact number on the inside of the windscreen and return to the car at the first opportunity.
