A lorry driver was caught on camera watching a Formula One documentary on his mobile phone while driving on the M5 motorway on May 12, police said.
The driver was caught as part of Operation Tramline, a HGV road safety project led by Highways England and Gloucestershire Constabulary.
This video shows officers in an unmarked lorry filming the lorry driver watching the documentary on his phone. Officers in the video can be heard saying the driver is also not wearing a seatbelt.
Police said they gave the driver a ticket for not being in proper control of the lorry and warned him about the potential consequences of his actions.
