Knees steering cars and inattentive driving is the kind of behaviour Western Bay of Plenty Police are trying to change.
Road policing manager senior sergeant Wayne Hunter is behind a "seatbelts and cellphones" initiative aiming to have drive securely fastened and to reduce the number of drives using their mobiles.
He said there would be staff out every day checking for the illegal behaviour.
This involved a "spotter", checking cars at one point of a road, who would then radio a colleague to pull the driver over.
While drivers had been generally good at wearing seatbelts, cellphone usage was not.
