Southern Police are urging motorists to drive with caution due to frosty conditions throughout Central this morning.

Police have reported freezing fog around Alexandra through to Cromwell, Upper Clutha and Tarras, leaving multiple roads icy with patches of black ice. Chec our daily Road updates here.

Motorists are asked to take the weather into account and drive to the conditions.

A spokesperson said the important thing was to slow down and be on the lookout for ice, fog or excess grit on the roads.

If a patch of road looks wet or damp, assume it’s black ice; let your car slow down on its own, and brake gently before you get to a curve.

Police also urge caution where there is freezing fog, which is when tiny, supercooled liquid water droplets in fog freeze instantly on exposed surfaces when surface temperatures are at or below freezing.

"Please drive with caution and do not take unnecessary risks."
