Dunedin drivers have performed well in their first month of not using handheld cellphones while in control of a car.
The ban on using handheld cellphones while driving became law on November 1.
Southern district police roading manager, Inspector Andrew Burns yesterday said he was aware of just three or four infringement notices being issued since then, "although there could have been more".
A four-day operation last week, looking for offences at "high-risk" intersections along Dunedin's one-way system, detected just two people using handheld cellphones, Insp Burns said.
"Pretty much what we've been getting is that people are behaving."
Cellphone offenders can be fined $80 and be given 20 demerit points.
The same operation detected 33 intersection offences such as running red lights.
Another 43 people were caught not wearing seat belts.
Insp Burns expected the effect of the rule change on crashes would not be known for some time.
