Ice, ice, maybe? Central North Island motorists asked to take care on icy roads


Waka Kotahi NZ Transport Agency is encouraging motorists to take care, drive to the conditions and allow more time for their journeys due to the possibility of ice on Central North Island state highways.

Waikato System Manager Cara Lauder says after a southerly blast and heavy snowfall like we’ve just had, the cold air and clearing skies often combine to create freezing conditions, which can lead to ice on the road.

“Winter roads require winter driving. Black ice can be hard to see and motorists should take particular care in shaded areas and on bridges.

“Consider leaving later in the morning to allow ice to thaw or earlier in the afternoon before ice has formed, and maintain a greater following distance between your vehicle and the one in front.

“Slow down and drive to the conditions.”

Waka Kotahi uses a combination of CMA (calcium magnesium acetate, a coating which reduces ice) and grit on the roads during winter to manage ice on the roads and our contractors are out applying this, often late at night and early in the morning, so motorists are asked to take care and look out for road workers.

Ms Lauder says a safe vehicle, equipped for the conditions, is also important.

“Ensure your car is safe, roadworthy and well equipped for winter driving, with a safe spare tyre, lights, brakes and windscreen-wipers all working, and a clean windscreen inside and out.

“It’s also a good idea to make sure your cell phone is well charged, and to carry a car phone charger or power bank. You should also carry blankets, snacks and bottle of water in case of an emergency or breakdown.”
