Police in South Yorkshire have warned drivers about new tougher penalties now in force for drivers caught using their mobile phones.
From Wednesday, March 1, motorists caught using a mobile phone at the wheel face a £200 fine and six points on their licence.
That is double the existing penalty of a £100 fine and three points on your licence.
New drivers who have been on the road for less than two years risk having their licences revoked if they are caught on their phones.
Police in Sheffield tweeted on Tuesday to warn drivers before the new new legislation came into force.
Sheffield Central Local Policing Team tweeted that evening: "The countdown is on from midnight tonight - on your phone and driving = £200 & 6points! Buy a hands free #handsfree #DontRiskIt"
