Police are urging people to drive carefully this morning after chilly weather has caused icy conditions on the region's roads.

There have been at least four accidents early this morning, which police say has been caused by the cold conditions.

The A140 (Ipswich Road) was partially blocked at the Hall Road Junction due to an accident, while north of the city the B1149 (Holt Road) was also partially blocked at the Short-Thorn junction because of an accident.

Traffic is now flowing as usual at these two locations.

Earlier today a car overturned on Hills Road between the Ashill and Shipdham junctions.

The incident happened at around 6.15am, and crews from Watton and Swaffham fire stations helped clear the scene.

No one was trapped in the car, but there are minor delays on the road as a result of the accident.

One crew from Earlham Fire Station was also at the scene of a road traffic collision at Honingham.

The East of England Ambulance Service Trust provided treatment at the scene.

In a message on social networking site Twitter, Norfolk Police said: 'It's been snowing, it's cold, it's icy, and there have been several accidents this morning, Drive carefully to the conditions.' Police are also warning motorists to expect delays as officers escort the transportation of a yacht through the county.

It will be moved from Ailswoth, Cambridgeshire, at 9am to Windboats Marine, Wroxham.

The 5.2 metre wide, 28 metre long yacht, weiging 48 tons, will be transported along the A47, A1074, A140, A1042, A1151 Wroxham Road, Grange Walk, and Grange Walk.

Delays could occur on these routes while the yacht is transported.
