Devon and Cornwall's road safety team have caught a driver filling out paperwork behind the wheel on a motorway.
The No Excuse safety team spotted the driver on the M5 this morning (4 September).
They posted the sighting on social media.
Police and Crime Commissioner Alison Hernandez praised the team for their actions and said: "I am shocked that people still think this kind of behaviour is acceptable."
In July and August the road safety team in Devon and Cornwall tweeted nine incidents of drivers using their phones behind the wheel.
