Nearly 600 people have been caught by police not wearing seatbelts on Devon and Cornwall roads since the end of September.
The incidents were detected by Aecom cameras, which use artificial intelligence (AI) to capture offences.
The cameras caught 590 people not wearing seatbelts and 40 people driving while using a mobile phone.
Police have described the figures as “alarming”.
They have been released by Devon and Cornwall Police to mark the end of national road safety week.
