The icy conditions and black ice on a number of roads this past weekend are likely to continue throughout the week as temperatures remain low across the South Island.
The NZ Transport Agency reminds all drivers to be ready for ice and grit – both require people to reduce their speeds and maintain safe following distances.
Transport Agency Journey Manager Lee Wright says shaded areas may be icy until midday and later in some places.
All state highways in the South Island are open this afternoon.
However, the following Nelson Tasman roads have ice and snow warnings in place:
- SH63 St Arnaud to Rainbow Skifield
- SH60 Upper Takaka to Riwaka
- SH6 Hope Saddle
Winter driving safety tips:
Look out for shaded areas caused by road cuttings and tall trees where the roads freeze sooner and ice may not thaw during the day.
Frost is more severe at daybreak, so be prepared for this after it becomes light. While it may not be frosty at 6am, it could be an hour or two later.
Allow greater following distances.
Black ice, while often hard to spot, is extremely hazardous and increases the risk of losing control and losing traction.
Take extra care on bridges and overpasses as black ice forms first on these surfaces making the road surface particularly hazardous.
