Senior Sergeant Anthony Bond, of Dunedin, said officers saw a 19-year-old man driving through Dundas St around 9am with his head out the side window.
The driver was stopped and approached by officers and was fined $150 for driving with a darkened windshield, which was covered in ice.
The incident reminded motorists to drive to the conditions and take an extra five minutes to defrost their vehicles before hitting the road and increasing their following distance.
“If you slide on the ice you don’t stop and you bump into other vehicles,” said Sr Sgt Bond.
Officers also attended an accident in Malvern St.
A mother with two daughters in her car came around the corner, slipped on sleet and crashed into two parked cars. A car driven by a 19-year-old woman then rounded the corner, heading east.
She braked for the first scene of the accident and swerved to the other side of the road, hitting a fence at a construction site.
The first woman was breath tested and noted a breath alcohol content of 701mcg, Snr Sgt Bond said.
The legal breath alcohol limit for adult drivers is 250mcg.
Shady parts of the city usually didn’t thaw in cold weather and were icy, especially in the morning, he said.
A total of seven frosty morning accidents were witnessed by police, Snr Sgt Bond said, including one in Maori Rd at 10:40 am.
A car driven by an 85-year-old woman slipped on ice and landed on a bank.
She was taken to hospital as a precaution but received only a minor cut on her head, Snr Sgt Bond said.
Another occurred at 10:20 a.m. when a 20-year-old man was speeding for the conditions, Snr Sgt Bond said.
His car fishtailed, crossed the centerline and collided with another vehicle in George St, near Willowbank Dairy.
There were no major injuries, but passengers were taken to hospital as a precaution.
