McDonald's have been warned over an action that could lead to a £200 fine while using its drive thru services.
It comes after a new mobile phone law came into force earlier this year, which could also see motorists hit with six points on their licence. People cannot use their phone while behind the wheel while being stationary in traffic, such as at traffic lights or motorway queues.
Drivers are only exempt from the new rule if they are making an emergency call - or if paying for a meal at a drive-thru using their device.
