Lower temperatures today and over the weekend mean that South Island drivers need to be aware of ice and black ice, particularly on bridge decks and shaded areas of the highway last to catch the sun.
Slow down accordingly, says Tresca Forrester, NZ Transport Agency Journey Manager. Crews will be gritting and applying de-icing compound to keep routes safely open as much as possible, however some highways with heavy snow may close if there is a risk of drivers getting stuck, particularly overnight.
Stay up to date and be prepared for the conditions. Latest updates and warnings here:
