Earlier today police reminded drivers to follow basic road safety advice. National Manager of Road Policing Superintendent Carey Griffiths said: "We all want our friends and whanau to reach their destinations safely. There are very simple things you can say and do to help each other stay safe on roads at a busy and high risk time of year."
Mr Griffiths encouraged drivers to keep to the speed limit, not to drive under the influence of alcohol, to wear seatbelts and take breaks when driving long distances.
"These are all road safety basics. I urge motorists to turn their brains on when they set off, and keep them on until they get there. "We all make mistakes, but not thinking clearly when driving, including driving while tired or distracted can have terrible consequences."
One person was killed on the roads last Labour Day weekend, 2013, police said.This was the lowest number of road deaths recorded over a Labour Day weekend since records began. There were however, 83 reported injury crashes which left 20 other people with serious injuries, police said.
