Whanganui Police are warning drivers to stay alert this month as they begin a crackdown on distracted motorists taking to the road.
Sergeant Colin Wright, officer in charge of the Whanganui Roading Policing Group, said police will be spending the next month focusing on driver impairment, particularly when it comes to mobile phones.
"The most prevalent distraction is drivers using their mobile phones while driving," Wright said.
"Using a mobile phone is wide and varied. It includes changing music, texting, checking a map, answering a call or having it in your hand for any other reason not already mentioned."
Wright said the reason the law exists is simple.
