If you eat, drink or use your phone behind the wheel in Canterbury, chances are you'll soon see flashing lights.
For the remainder of the year, police in the district will regularly target drivers who are not paying full attention to the road.
The aim of the crackdown is to reduce the number of crashes caused by mobile phone use and other distractions, Sergeant Alex Pickover said.
"There have been tickets issued for using a cellphone while driving, we've been doing checkpoints around the Selwyn District in relation to cellphone usage."
For using a mobile phone while driving, drivers can get an $80 fine and 20 demerit points.
