Drivers in Northern Ireland are the third worst in the UK for using mobile phones while on the road, new figures reveal.
More than 5,000 were caught on the phone behind the wheel last year.
Across the UK, 70,945 motorists broke the law by using a hand-held mobile while driving.
The worst police region by far was Thames Valley, with 9,242 offenders. Essex was second with 5,702, and Northern Ireland third with 5,013, according to figures compiled for insurer ingenie.
Figures obtained by this newspaper show police made 41,013 detections for mobile phone use while driving from January 2011 to December 2015.
Mobile phones were directly to blame for 37 accidents in which someone was injured.
Two people were killed and 11 others suffered a serious injury.
Drivers are given three penalty points and a £60 fine for using a phone at the wheel.
Ingenie CEO Mike Kettringham said: "We were shocked to see the breakdown of cases. It is clear that drivers haven't feared the punishment."
