When temperatures fall to sub-zero, the number of deaths from heart attacks peaks three days later, from strokes five days later and from respiratory infections ten days later.
When snow or icy roads are forecast you should adjust your driving to suit the conditions. Black ice isn't always visible and so can be an even greater hazard for both motorists and pedestrians. Black ice may be formed when rain or drizzle fall on a road surface which is at a temperature below zero.
