This week has seen a return to the snow which plagued the country last winter.
It is widely accepted now that global warming could herald in a new ice age - so as the planet heats up we can expect much more in the way of sub-zero temperatures and arctic conditions.
In these temperatures it is essential to pay attention to safety when driving. This means observing a few basic precautions when you set out from your house.
A little maintenance will help to ensure that you are not stranded later. Before you go anywhere, open the bonnet.
