Hamilton firefighters are urging motorists to be cautious after two serious crashes in foggy conditions.
One crash has left a woman fighting for her life after a brush with a milk tanker, while a motorist at Whatawhata had a lucky escape after ploughing through a fence and over a ditch into a power pole.
Hamilton's Te Rapa station officer Brett Couper said both crashes had a familiar theme - fog.
He reminded drivers to take more care and drive to the conditions as there was now more traffic on the roads.
The first crash saw a car glance a milk tanker on Telephone Rd at Puketaha about 7pm yesterday.
