We Say/You Say: Winter Driving

Reporter Hamilton Press

Hi Hamilton,

Have you had any close shaves because of hazardous winter road conditions?

There were several crashes on Monday morning in the Waikato region as a result of icy conditions.

Black ice is incredibly difficult to spot for the average motorist and the AA recommends drivers pay attention to the weather conditions the night before setting out.

Temperatures below zero, valleys and dips in the road and shaded areas where the road won't warm up as quickly are all factors in black ice formation.

"You don't want to slam on your brakes if you do get onto ice and feel the vehicle starting to slide. That's actually likely to make the vehicle go more out of control," AA spokesman Dylan Thomsen said.

Multiple precautions are taken by Waka Kotahi (NZTA) to improve the safety during the winter.

The agency contracts Downer workers to drive hundreds of kilometres along stretches to detect wet patches of road as they are freezing.

Calcium Magnesium Acetate (CMA) is sprayed on roads and bridges in very cold areas to stop ice from forming. The chemical acts by lowering the freezing temperature of the water.

Accidents are also mitigated when asphalt is sprinkled on at-risk stretches of road.
