The East of England Ambulance Service NHS Trust is asking drivers to be careful on the roads.
Glenn Young, head of the health and emergency operations centres, said: “Clearly people are heeding the advice that the police, ourselves and motoring organisations are giving out to take extra care and only to make journeys that are absolutely necessary.
"While the snowy and icy conditions continue to present a hazard, particularly on smaller roads and side streets, motorists should remain particularly careful."
Drivers should remember braking distances and be aware when emergency vehicles are approaching on blue lights; consider your driving speed to avoid sudden braking, and move safely out of the way of emergency vehicles.
Patients who do not have a serious or life threatening condition are asked to call NHS Direct on 0845 46 47 or their local GP or pharmacist.
