Members of the Derbyshire Roads Policing Unit were called to the incident on the A61 in the town after one car had gone into the back of another.
Officers said that fortunately there were no injuries from the incident.
But drivers passing by the scene of the crash may still get hurt – in their wallets.
The roads policing unit said: “To the drivers on the opposite carriageway recording on their phones, not in full control of your vehicles, notices of intended prosecution are in the post.”
It’s illegal to hold a phone or sat nav while driving or riding a motorcycle. You must only use your phone if you have a hands-free device or dashboard mount.
You can get six penalty points and a £200 fine if you use a hand-held phone when driving.
