Charles Dawson: AutoSense CEO on the new data revealing school runs are the most dangerous times on the road - Heather du Plessis-Allan Drive

New Zealand roads are about to re-enter a dangerous window as schools return for term one.

A report from driver safety advocacy group AutoSense claims accidents linked to fatigue happen most between 7 and 8am, the hour children head to school.

CEO Charles Dawson says fatigue is driven by our body clock - and it can be dangerous.

"Any vehicle that has a human behind the wheel is going to be prone to this, it's all about our natural physiology."
